Cruise Control Not Working

It would be difficult to find a vehicle on the road today without cruise control. This invaluable feature makes driving long distances easier but can also cause trouble when it malfunctions. Understanding the reasons your cruise control stopped working ensures that you can get the problem fixed quickly for a more enjoyable ride. 

While this fault can cause issues with the cruise control system itself, there could also be an effect on the acceleration of your vehicle. That’s why you want to have it looked at as soon as you notice a problem. Let’s take a quick look at the reasons your cruise control may have stopped working.

Reasons Why Your Cruise Control Stopped Working

The most common reason a cruise control stops working is due to a blown fuse or a defective brake pedal switch . It can also be caused by issues with the throttle control system or the ABS. In older cruise control systems, it can be caused by a broken vacuum line.

Here is a more detailed list of the possible reasons your cruise control is not working:

1. Blown Fuse

broken fuse

All electrical systems in the vehicle are controlled by fuses. Your cruise control system is attached to a fuse that can blow if there is a short circuit or fault. Without a good fuse, the cruise control system can’t work at all.

Thankfully, it’s not difficult to find and replace a blown fuse. Look in the owner’s manual to find the fuse that corresponds with the cruise control technology. 

2. Defective Brake Pedal Switch

The brake pedal switch is responsible for turning the brake lights on and off based on the pedal position. Cruise control systems are designed to disengage whenever your brake pedal gets pressed. 

Because the cruise control is wired into the brake pedal switch, any fault can cause it to stop working. When the brake pedal switch malfunctions, the car believes the brakes are engaged, causing the system to turn off automatically. Not only that, but your car’s brake light might also be stuck on, leaving confused drivers in your wake. 

3. Malfunctioning Speed Sensor

Speed sensors are located on every wheel or differential. The purpose of these sensors is to monitor the speed of the wheels to determine if traction control is needed. 

The speed sensors are also part of the cruise control system. When a sensor fails, the cruise control can stop working and the speedometer might act strange as well. 

If there is an issue with a speed sensor, it will often show with an ABS warning light or a check engine light on the dashboard.

4. Electrical Issues

The cruise control system is electronic, with many components working together to make the system operate. If the cruise control fails to work, you want to check the wiring harness and associated connectors for a fault.

You also need to ensure that the voltage source is supplying enough power to the system. Even the smallest fault can cause defects with the cruise control. In many cases, there can be an issue with the cruise control lever or buttons causing the cruise control to not engage.

If your cruise control buttons are located on the steering wheel it could also be caused by a bad clock spring, which is located behind the steering wheel.

Check the system with an OBD2 scanner to look for any trouble codes related to the cruise control.

5. Damaged Vacuum Actuator, Hoses or Cable (Older cruise control)

If you drive an older vehicle with cruise control, you might have an issue with the vacuum actuator or the cable that connects to the throttle. If there has been damage done to the vacuum hoses or the actuator, the cruise control will stop working altogether.

Additionally, the cable linking the actuator to the throttle must be in good shape. If it has been broken, the cruise control will fail. 

What is Cruise Control?

Cruise control is a feature that is used when you are traveling at a consistent speed. Cruise control was first introduced for automobiles in the 1950s. However, it took many years before it became a staple in the modern vehicle.

This electrical system allows you to set a predetermined speed and take your foot off of the gas pedal. If you are on a long drive, there is less fatigue because you don’t have to try to maintain your speed. Cruise control can also benefit fuel economy because the vehicle uses less fuel when traveling steadily. 

In newer cars, you might be able to find adaptive cruise control , which is a smart technology. Adaptive cruise control allows you to travel at a predetermined speed, but it also helps to maintain a safe distance from the vehicles in front of you with the help of sensors. With conventional cruise control, you need to take over when the car in front of you slows down, but that’s not the case with adaptive cruise control. 

There are also vehicles nowadays with not only cruise control, but fully self-driving vehicles . We will most likely see much more of this in the future.

Cruise Control Repair Cost

The cost to repair your cruise control system depends on what caused it to fail. If you need to replace a cruise control or brake switch, you might spend between $125 and $350, including parts and labor. However, the cost to change a fuse is only a few dollars and you can perform the replacement yourself in just a matter of seconds. 

On the other hand, when something major fails, such as the actuator, you could be looking at a much higher repair bill. In some vehicles, the cost to replace a cruise control actuator can cost more than $700. These costs rise if you drive a luxury vehicle or one that is difficult to get parts for. 

It might not seem immediately important for you to fix the broken cruise control, but this defective system can affect other performance aspects. You could start to notice issues with acceleration or have trouble with the speedometer. To play it safe, it’s always best to have the cruise control repaired as soon as you notice a problem.

Is there a fuse for the cruise control?

Yes. If the cruise control is installed from the factory, you should check your car’s owner’s manual for the fuse location. If it’s an aftermarket cruise control, you’ll need to follow the wires to find the fuse.

Does the brake switch affect the cruise control system?

Yes. The brake switch affects the cruise control system. The brake switch sends a signal to the cruise control system to let it know when the brakes are being applied for the engine to know when it should stop accelerating.

Will the cruise control work if the check engine light is on?

The cruise control function will be disabled when the check engine light is on in most car models, even if the cause of the check engine light is not the cruise control itself. This is mainly due to safety reasons.

Can a vacuum leak affect cruise control?

Older vehicles use vacuum to control the throttle for the cruise control, and in this case a vacuum leak can heavily affect the cruise control. However, modern cruise controls are fully electric and in most cases will not be affected by a vacuum leak if the check engine light is not illuminated.

Although many people may think that the cruise control system is unimportant and not worth spending money to repair, the problem can be caused by a faulty part that will affect the engine’s performance or durability. Therefore, it is best not to ignore the problem if your cruise control is not working without first diagnosing the car properly.

If your cruise control still isn’t working after trying all the tips in this article, it’s probably time to take it in for a professional opinion from a mechanic. It may be a more serious problem that requires replacement parts or repairs. In the meantime, drive safe and enjoy the open road!

14 Reasons Why your Cruise Control may NOT Be Working

The reason for your cruise control not working could be as simple as a blown fuse to really complex electrical problems. Defective switches, sensors, and even “check engine” light, all could contribute to this problem.

If you like to travel and own a car fitted with cruise control, you know how comfortable it can be to maintain a constant speed! When a cruise control system gets damaged, it is just as annoying as it is dangerous.

Cruise control is connected to several components of the car, and when it fails it can mean that something could be wrong with the CC itself. It could also be a signal that something wrong is happening with any other component of the car.

Why is my cruise control not working?

In this article, I am going to show you the main reasons why your cruise control may not be working (from the simplest to the more complex ones):

Reason #1. Bad or blown fuse

The cruise control’s circuit (like many other electronic components of your car), is protected by a fuse that will blow to protect the system from short circuits and overloads. If your vehicle’s cruise control fuse is blown, the system will stop working.

You can replace the fuse with a new one of the correct amperage, according to your vehicle’s owner manual. If the new fuse doesn’t blow again, everything will be ok; if the fuse blows again, you have to keep searching for what is making that fuse blow.

Reason #2. Burnt brake lamp

Some cruise control systems are disabled when the brake lamp is blown. Check your brake lights. If you find a burnt brake light, just replace it and test the system again.

Reason #3. Defective brake light switch

A defective pedal switch can also make your cruise control stop working. Remember that all cruise control systems are automatically disengaged as soon as the brake pedal is pressed down.

If the cruise control didn’t stop working when a fault in the brake light or brake pedal switch is detected, it could be dangerous; that’s why the CC control unit constantly monitors the status of this switch.

Reason #4. Clutch pedal switch deactivation (for manual transmission vehicles)

Cruise control is deactivated when the clutch is pressed by the driver in manual transmission cars. The CC control unit monitors this switch as it does the brake light switch.

Reason #5. The vehicle speed sensor is not working

A vehicle’s cruise control needs to be able to determine the vehicle’s actual speed. This enables the system to determine how much throttle needs to be applied in order to keep a certain speed, among other things.

The speedometer speed sensor is not always the sensor used by cruise control. Some systems rely on the ABS speed sensors, others do an average and some have a dedicated speed sensor.

If the system can’t detect the vehicle’s speed or detects a problem with the speed sensor, it will stop working.

Reason #6. Faulty throttle body or accelerator pedal

In modern engines, the throttle body is driven electronically by the engine control unit (ECU), and the accelerator pedal works like a potentiometer. The processor managing the cruise control system will act as the accelerator pedal, sending more or less voltage to the throttle body to open or close the throttle body’s butterfly valve.

If there is a problem with your vehicle’s throttle body, your cruise control won’t work.

Reason #7. Check Engine light is “ON”

If your vehicle instrument panel has the “Check Engine Light” ON and the fault stored in the ECU’s memory is related to some component vital for the cruise control system, you will not be able to use your cruise control until you have fixed that problem.

Reason #8. Faulty steering wheel’s spiral cable/clock spring

The spiral cable connects all the switches from the steering wheel (in case your steering wheel has switches) to their respective modules. This includes the connection of the driver’s airbag.

These wires (also called clock springs) are prone to get cut. A faulty spiral cable may have an open circuit making it unable to reach the vehicle’s cruise control module (CCM).

Reason #9. Bad Cruise Control Switch

Your vehicle’s cruise control switches have internal contacts that wear out. If that happens, the switches won’t be able to contact the CCM.

Depending on which buttons are faulty, your whole cruise control can stop working or just some functions won’t work.

Reason #10. Electrical problems with different modules and wiring

Modern cruise control systems use electrical and electronic components, and they are connected to other modules and systems of the vehicle. Some of these systems are the ECU, ABS, and/or Stability Control Systems like ESP.

The CCM makes a check of these systems once the key is switched to ON, and if some of these components are not working in optimal conditions, the CCM won’t engage. If none of the above items seem to be the problem, the vehicle needs to be taken to a professional who can perform a full scan of all the components, check that all the voltages, wiring harnesses, and connectors are ok.

The professional is going to detect if there are any connection problems between modules and will be able to find the reason why the cruise control is not working.

Reason #11. Dirty or faulty camera or sensor (only for vehicles fitted with adaptive cruise controls)

Newer vehicles have adaptive cruise control systems. These devices not only keep a fixed speed by the driver; they also can detect other vehicles ahead and behind and are able to keep a safe fixed distance to avoid collisions.

Some of these new systems have laser sensors while others have cameras to calculate the right distance to follow considering the vehicle’s speed and acceleration. Any problem with the sensors will prevent adaptive cruise control from working.

Problems with older cruise control systems

Before electronic injection and electronic throttle bodies, some cars had the cruise control function. In fact, the first cruise controls were introduced in the early 1950s.

These electromechanical cruise controls are pretty simple. They have a vacuum actuator connected to the throttle linkage that opens and closes the throttle to maintain the vehicle’s speed.

In early injection cars, the throttle linkage was replaced by a cable. Some common faults of these old cruise control systems are:

  • A faulty vacuum actuator. Vacuum actuators have a diaphragm inside that can break. Any vacuum leak will lead to failure.
  • Faulty vacuum control solenoid. It can prevent the actuator from operating normally.
  • Broken throttle cable. If the throttle cable or linkage is broken, it needs to be replaced.

I hope you enjoyed my guide to cruise control problems. Even though it doesn’t explain how to fix your cruise control, it gives you an idea of where to start looking if you are going to do it yourself.

Now you will have an idea about how the system works and what are the possible reasons why it’s failing (in case you have to take your vehicle to a shop to be repaired).

7 Reasons Why Cruise Control is Not Working

cruise control not working

Cruise control has been around since the late 1950s. There was a time when you could only find this convenient feature in a few model vehicles. Nowadays, it seems like virtually every model vehicle on the road has a cruise control feature.

Cruise control not engaging seems like a trivial issue, but the inability to activate this convenient feature can certainly dampen any road trip. While cruise control failures “rarely” pose safety risks, determining the root cause is necessary to restore its use. Let’s look at the common causes of cruise control malfunction.

Table of Contents

Cruise Control Problems (Accelerating or Maintaining Speed)

If your cruise control feature malfunctions and stops working altogether, you may not think it’s an immediate concern. You’ll probably figure that you just can’t use cruise control anymore until you get the problem fixed.

However, the problem with your cruise control might be related to an acceleration issue too. In fact, there are components of cruise control which can have an adverse effect on the acceleration if those components are bad. That is why you need to be aware of what causes cruise control issues.

Common Causes of Cruise Control Not Working

There are several possible causes of cruise control not working. Below are the top 6 most common causes. Check each of these areas and see if they’re the cause of your cruise control issue. In many cases, the remedy to the problem is not that complicated or expensive.

1) Cruise Control Switch

cruise control switch

The cruise control switch is what you use to set your cruising speed. This information is transmitted to the engine control unit and cruise control module in order to sustain the acceleration speed.

If the contacts inside the cruise control switch were to wear out, then the module and unit might not receive the necessary speed information it needs to keep the acceleration going. In response, the system will deactivate entirely and cancel the current cruise acceleration set.

2) Brake Light Switch

bad brake light switch

Normally, you press the brake pedal to turn off cruise control. The brake light switch must be detected by the cruise control system for this to happen.

If it cannot detect the switch, then cruise control will disable itself automatically until the brake light switch issue is fixed.

A faulty brake light switch can also cause your brake lights to stay on .

3) Blown Fuse

fuse box

The electrical components of the cruise control system are protected by fuses. Like inside your house, it is possible to blow a fuse. This will cause the cruise control system to turn off until the fuse is replaced.

4) Check Engine Warning Light

oil pressure check engine light

If the check engine warning light comes on, it usually means there is a problem with your transmission or engine. Once the engine control unit detects this problem, it may disable your cruise control system in response as a safety precaution.

Until you fix the engine issue, the cruise control will stay disabled.

5) Vehicle Speed Sensor

transmission speed sensor

Most vehicles have a few vehicle speed sensors to transmit speed information about the vehicle to the engine control unit and the cruise control module. The only way your cruise control module is going to know how fast the vehicle is moving is if the vehicle speed sensors feed this information to it.

If the module cannot detect the speed because of faulty speed sensors, then the cruise control system will automatically deactivate.

6) Electrical Issues

car wiring low voltage

There are several electrical components connected to the cruise control system. The connectors and wiring harnesses, and ground straps are definitely components that you need to check when the cruise control stops working.

Make sure the source of the voltage is still supplying power to the system as well. If any of these components are loose or damaged, then it would explain why the cruise control isn’t functioning.

7) Loose or Broken Cruise Control Cable

cruise control cable

Older vehicles that are equipped with cruise control have two throttle cables – one for the gas pedal and one for the cruise control system.

These cables may stretch over time. If the cruise control cable has stretched or is broken, the cruise control system will not be able to operate the throttle plate properly.

Adaptive Cruise Control Specific Problems

adaptive cruise control

Adaptive cruise control gives an extra layer of convenience while driving, as it adjusts your vehicle’s speed based on the distance to the car in front of you. However, this presents additional causes of cruise control failure.

One issue you might face is obstructed sensors. Both radar and cameras are important components of the adaptive cruise control system. When there’s dirt, debris, or ice covering these sensors, your cruise control can stop functioning. To prevent this, regularly clean your vehicle’s sensors, making sure they’re unobstructed.

Separately, failed cameras can also be a culprit. If the cameras aren’t working correctly, you may see an error warning. It’s best to get this checked by a professional to determine whether the cameras need repair or replacement. Hopefully it’s not as they are an expensive replacement.

Apart from cameras, adaptive cruise control relies heavily on radar technology for proper functioning. A misaligned or malfunctioning radar sensor can cause your system to behave irregularly. Again, consult a qualified technician to diagnose the issue and, if needed, recalibrate or replace the radar system.

Safe Driving Without Cruise Control

When cruise control systems fail, it presents challenges adjusting to speed management without the consistent pacing it provides. But there are a few things you can do.

  • Focus on scanning gauges more frequently to stay actively aware of mph.
  • Avoid zoning out on long hauls.
  • Set phone alerts every few miles to remind checking current travel speed.
  • Know highway speed limits well so mentally benchmarking against them continues subconsciously.
  • Take frequent breaks stretching legs to re-energize alertness until able to diagnose cruise faults.
  • Consider alternative adaptive cruise technologies equipped on newer vehicles if financially viable, providing automated incremental slowing when closing distances on lead cars.
  • Remain vigilant of lead car distances and your own speed fluctuations.
  • Utilize open lanes with fewer surrounding vehicles if possible, reducing needs for continual minor adjustments.
  • Stay alert with renewed attention and defensive awareness absent cruise controls automated convenience until repairs are completed.

Intermittent Fault Identification

When cruise controls experience occasional yet repeating failures, meticulously logging every instance of malfunction helps uncover patterns guiding toward root causes.

Date and time each cutoff or disengagement that happens while activated. Detail any environmental or operational conditions present such as: weather, bumpy vs smooth roads, stop & go traffic versus highway speeds.

Reviewing complete repair histories alongside these event logs indicates if previously replaced components only provided temporary fixes before subsequent re-failure later on. Share documented patterns of when and how interruptions occur with shop technicians to guide their pathway tracing and component testing.

The goal is determining if specific elements like an old switch, wire insulation or solder joint chronically breaks down only under certain temperature, vibration or usage strain thresholds.

Cruise Control Repair Costs

So, your cruise control decided to take a break, and now you’re wondering how much it’ll cost to fix it. Well, repair costs vary depending on the specific issue and your vehicle’s make and model. This section will provide you with an idea of what to expect in terms of expenses.

Let’s look at the common reasons for cruise control problems and their approximate price range for replacement or repair:

  • Faulty Cruise Control Switch – $100 – $200. A bit more expensive than a brake light switch.
  • Blown Fuse  – $5 – $30. Quick and affordable to replace.
  • Faulty Brake Light Switch  – $50 – $150. Can be a bit pricier but still manageable.
  • Defective Speed Sensor – $100 – $300. Falls somewhere in the middle of the price spectrum.
  • Throttle Control System Issues – $200 – $600. More expensive to diagnose and fix.
  • ABS-related Problems  – $200 – $1,000. Can also be quite costly to repair.
  • Broken Vacuum Line  – $50 – $150. Applicable to older systems and typically inexpensive to fix.

How Does Cruise Control Work?

If you normally drive long distances, especially on the interstate, then cruise control lets you take your foot off the gas while the car maintains the same speed, giving your leg a rest. This may seem like merely a luxurious feature rather than a necessity, but many people depend on it for safe driving.

There are several different types of cruise control systems, but all implementations share similar basic components. There is a sensor to measure vehicle speed, a throttle position sensor , and some mechanism to control the throttle plate without the use of the gas pedal.

Outputs from the speed and throttle position sensors allow the engine computer to determine how much the throttle plate needs to open or close to maintain speed.

Cruise control systems may also use sensors in the transmission, taking the current gear and engine vacuum into account. Throttle position will be different in each gear at a given speed, especially when driving over hills.

13 thoughts on “7 Reasons Why Cruise Control is Not Working”

have a 2006 VW new Beetle my cruise works fine until i go to pass some one ,any idea what would cause it to do this? ?

When you hit the gas pedal to overtake, you might be disengaging cruise control.

i’ve heard that bad fuel can create such issue. As stated above, the Check Engine light will come on as part of the safety features to inform you something is not right. Cruise control picks up on this and shuts down.

The engine light was flashing then it stopped then started again, the cruise control is disabled but did come on a couple of times but went off when the engine needed to accelerate, the engine shakes when I. Accelerate too.

my aftermarket cruise on a 2013 Kio Rio LX wont light up

You’re going to have a hard time with finding help for that without providing the name and model of the aftermarket system. It might be best to take it to someone so they can troubleshoot in person.

My cruise indicator light will turn on but when I try to set the speed the light will shut off and not turn back on until I restart the engine. Any ideas what it might be?

Did you ever figure this one out. I got 99 Durango does this too

Cruise control goes rite into high speed when turned on,what could the problem be?

This helped me a lot. I got more out of your 6 reasons a cruise control may not work, than when I inquired about the same situation and got nothing. Thank You, Janet M.

Thanks for the feedback, Janet!

Cruise control not working — causes and fixes

Troubleshoot and fix non-functioning cruise control in your vehicle..

a close up of a car steering wheel.

Cruise control is one of the most useful modern driving features which makes every longer journey easier. It lets you travel at a constant speed and reduces the pressure on your foot caused by frequent gas pedal pressing.

However, in case of the cruise control not working , it’s important to deal with the problem right away. If you turn the system on while it malfunctions, you might not be able to turn it off during the drive. So, you can follow this guide to get all the information about the most common reasons for failing cruise control and get advice on how to fix it.

What’s cruise control and how does it work?

cruise control system problems

To get a better understanding of possible reasons behind malfunctioning cruise control, it’s time to deal with the basics behind the system. Cruise control is an electronic system that helps you maintain a certain speed level for extended periods without holding your foot on the gas pedal.

While driving regularly, the pressure with which you push the gas pedal is transmitted to the throttle position sensor which controls the throttle valve. If you press the pedal further down, the valve gets open, and more air flows into the engine.

On the other hand, if you apply less pressure, the valve is nearly closed, slightly letting air in. The engine control unit (ECU) uses these measurements to calculate fuel injection and translate the pressure into driving power and speed.

The modern cruise control system controls the throttle position sensor and other sensors and electronically simulates the pressure on the gas pedal. Even some older vehicles have cruise control, but in these cars, cruise control used a cable that physically maintained pressure on the accelerator.

With modern improvements, there’s also the introduction of adaptive cruise control which uses several drive assist systems to maintain your speed. These include lane assist and the possibility to increase and lower the speed by pressing the button.

Modern cruise control also measures the speed of the car in front of you in the lane to maintain a safe distance. If you are a car guy, you probably enjoy having control over the machine yourself. However, cruise control is extremely useful during a long highway ride, since it reduces the fatigue and pain of pressing hte4 accelerator for hours.

Reasons behind cruise control not working

cruise control system problems

Now that you know how the cruise control system works, it’s time to dig deep into the possible reasons behind its malfunction. First, we come by electrical issues since this is an electrical feature after all. However, there are also other possible reasons, so let’s take a look at a few of the most common ones:

  • Problems with the throttle body
  • Malfunctioning sensors
  • Blown fuse and electrical issues
  • Faulty brake pedal switch
  • Bad mechanical cruise control cable

All of these reasons can make your cruise control ineffective and the worst thing is if it malfunctions while you are using it. It’s also a bad thing since cruise control saves gas while on long journeys down the highway, so you’ll want to fix the problem based on the listed reasons as soon as possible.

How do throttle body issues affect cruise control?

In case the throttle body valve gets stuck, or the throttle body gets clogged, you’ll have a hard time using your cruise control system. The worst thing that could happen in this case is if the gas pedal gets stuck in position, which also affects your driving regardless of the cruise control.

You can clean your throttle body with specific products to be able to use cruise control again and to ensure proper air intake into your engine. Modern cruise control systems lock the throttle valve in a position to ensure even air intake, so if the valve malfunctions, you won’t be able to use it.

Bad or malfunctioning sensors

As mentioned, cruise control is an electrical system and it uses the readings of multiple sensors to adjust and maintain your driving speed. Out of these sensors, the throttle position sensor and the speed sensor are most relevant for the system’s operation.

We already mentioned how the throttle position sensor affects the control of the throttle valve, and the speed sensor monitors the driving speed. It sends information to the ECU regarding the traction control system by the speed readings. If the sensor fails, you’ll likely experience some strange speedometer action and an anti-lock braking system ( ABS ) warning light on the dashboard .

So, the cruise control system might also fail, as it uses the readings of these sensors as well as the data of the ECU regarding traction control and ABS usage.

Blown fuse or electrical issues

One of the easiest fixes for a bad cruise control system is to just replace a blown fuse. If this happens, you can just take a look at the fuse box by referring to the owner’s manual of your vehicle for the exact location. Usually, there’s a fuse box under the hood or just the left of the steering wheel in the car’s interior.

If there’s a circuit short, the fuse might blow, and simply replacing it will bring the system back on again. Also, other electrical issues can occur such as a bad connection with the control buttons on the steering wheel or electrical connections

Bad brake pedal switch

The cruise control system in your car is connected to the brake pedal switch. It’s the switch that communicates with your tail lights and turns them on as you press the brake pedal. If the switch goes bad, the signal gets interrupted, and it can reflect on your cruise control system as well.

Most cruise control systems are designed to disengage as you press the brake. So, if the computer believes the brakes are pressed due to a faulty switch, it will turn off the cruise control system.

Worn mechanical cable for older cruise control systems

As mentioned, old cars with cruise control often use a cable that locks the accelerator in place as you activate the system. This ensures that the accelerator pressure stays the same during the time the system is active.

The mechanical system also uses an actuator and hoses, and these could all wear off due to frequent usage. So, if any of the mechanical components malfunction, you won’t be able to use the cruise control system.

Fixing a failed cruise control system

If your cruise control system works on some occasions, while it fails on others, don’t use it while driving. It’s not safe and the best thing you can do is inspect the system based on the reasons behind a malfunctioning cruise control.

You can do some repairs yourself, including testing and replacing a blown fuse. On the other hand, you’ll need the help of the mechanic to replace a bad actuator in mechanical systems or to fix the brake pedal switch.

Overall, if you spot your cruise control not working, you shouldn’t use it while driving until you make the repairs. Some systems will fail on some occasions, while you’ll sometimes be able to use them regularly. It’s still better to inspect the system based on the common reasons behind its failure listed in this guide and make proper repairs.

This way, you can save yourself some trouble, along with gas and effort while driving with the cruise control system active.

What could cause the cruise control to stop working?

A blown fuse or a faulty brake pedal switch could cause the cruise control to stop working, along with malfunctioning sensors.

How do I know if my cruise control fuse is blown?

You can know if your cruise control fuse is blown by taking a look at the fuse box, and you can find the fuse box location in the owner’s manual.

Where is the fuse for the cruise control?

The fuse for cruise control is located within the fuse box under the hood or at the left of the steering wheel.

How much money does it cost to fix cruise control?

It costs anywhere from $10 for a replacement fuse, to $500 for the actuator or the throttle body repair to fix the cruise control system.

Cruise control reduces stress and fatigue on long drives, but if the system isn't working properly, it can become dangerous. If your vehicle's cruise control isn't working, one of the following nine issues may be the root cause.

How Cruise Control Works

Cruise control is a system to maintain vehicle speed without direct driver input. When you want to engage cruise control, you first turn the system “On” with a button or switch. However, this alone does not start the cruise control. When you “Set” cruising speed, the cruise control module (CCM) records the current speed, then takes control of the throttle body to maintain vehicle speed. When vehicle speed increases or decreases (due to wind or hills, for example), the CCM decreases or increases throttle body opening accordingly.

By modulating engine speed, the CCM can maintain your desired cruising speed on the highway. You can increase or decrease cruise speed by tapping a button or lever, and you can cancel cruise control by hitting the “Cancel” or “Off” buttons or stepping on the brake.

Throttle body control has changed over the years. Early systems used a vacuum motor and cable, but these eventually changed over to electric motors. Most recently, with the development of drive-by-wire or electronic throttle control systems (ETCS), cruise control is built into the engine control module (ECM), which controls the throttle body electronically.

Basic cruise control systems still require the driver to pay attention to changing road and traffic conditions. Adaptive cruise control systems, sometimes called "smart" cruise, use radar or laser detection to maintain safe distances from vehicles ahead. Some adaptive cruise control systems merely reduce engine speed to maintain distance, but some of the newest adaptive cruise control systems can also engage the brakes to slow or stop the vehicle. Still, even with adaptive cruise control, it's important that drivers never take their eyes off the road.

Why Is My Cruise Control Not Working?

There are a few basic ways that cruise control can fail, depending on how the system is designed. You may not be able to do much about ETCS cruise control systems, but there are a few things you can check:

Brake Light Switch – As cruise control is automatically cancelled by depressing the brake, some vehicles may disengage cruise control if it cannot detect the brake light switch.

Brake Lights – In some systems, cruise control is disabled when a brake light is blown. Aftermarket lighting, such as LED brake light conversion, might trick the CCM into thinking a brake light is blown, as LED bulbs draw less current than incandescent bulbs.

Fuses and Relays – On some vehicles, fuses and relays are used to protect the cruise control actuator circuit . If the fuse is blown or the relay is faulty, the system won’t work.

Spiral Cable – Many vehicles mount the cruise control switch on the steering wheel. A faulty spiral cable may have an open circuit, preventing the switch from contacting the CCM.

Control Switch – If the internal contacts wear out, the cruise control switch may not be able to contact the CCM. This might disable cruise control completely, or it might not react to the cancel or accelerate functions.

Check Engine Light – On some modern vehicles, particularly those equipped with ETCS, cruise control may be disabled if there is an engine or transmission problem .

Vacuum Leak – Some older vehicles used vacuum actuators to control the throttle body during cruise control operation. If there is a leak, such as a cracked hose or tube, the system won’t work. A vacuum leak might cause the engine to idler higher or set a fuel trim code.

Vehicle Speed Sensor – There are usually multiple vehicle speed sensors (VSS) on any given vehicle. The CCM might use a VSS feed from the ECM, instrument cluster, or transmission. If that signal is lost, the CCM can’t detect vehicle speed, disabling cruise control.

Electrical Problems – As most cruise control systems use electrical or electronic components, any diagnosis should include a thorough check of source voltage, wiring harnesses, and connectors. Anything loose or broken could disable the system entirely.

If your cruise control isn’t working properly, avoid using it until it is repaired. A faulty cruise control system may not cancel on demand, which will create a safety hazard for you and those around you. After assessing your cruise control yourself, take your vehicle to a trusted mechanic for a check or a couple diagnosis and repair.

Why Is My Cruise Control Not Working? 6 Common Reasons

When your cruise control stops working, it can be quite an inconvenience. In this expert guide, we’ll talk about the most common reasons it can fail.

If you’re old enough, you can probably remember driving on road trips , or even just on your daily commute to work, before cruise control was a thing. It can be downright exhausting.

Unfortunately, even modern-day cars can have a failing cruise control system and it can seem like you’ve been thrown back into the stone ages.

Okay, that might be a bit dramatic, but it really can be annoying when cruise control stops working. But why does that happen?

The most common reasons that your cruise control might stop working include a bad cruise control switch, a blown fuse or relay, problems with the engine or transmission, a faulty vehicle speed sensor, a bad brake pedal switch, or a broken cruise control cable.

If your car’s cruise control isn’t working, it can be a major pain.

What do you do if your cruise control stops working? Here are some of the most common reasons why it might not be working, and how to fix it!

To fully understand why cruise control stops working on a car, we researched the most common reasons so that you know exactly what’s wrong with it.

Since we’ve already done the research for you, all you need to do is run through the list of common reasons below and you’ll be able to get your cruise control figured out in no time.

How Does Cruise Control Work?

Before we get into the reasons that cruise control might not be working in your car, it’s important that we first explain how the cruise control system works in the first place.

By understanding how cruise control works and what components are involved, you’ll have a much better understanding of why the issues below can prevent cruise control from working.

So, how does cruise control work?

The cruise control system in your car is made up of a few different parts. There’s a cruise control switch, which is usually located on the steering wheel, that turns the system on and off.

There are also fuses and relays that power the system, and a speed sensor that tells the system how fast the car is going. These sensors report back to the cruise control module, which controls a cruise control servo.

This servo is what actually controls the throttle of your car , and it’s what tells the car to speed up or slow down to maintain the cruise control speed.

Finally, there’s a brake pedal switch that tells the system when you’re braking and a cruise control cable that connects the accelerator pedal to the cruise control system.

All of these parts and pieces work together to enable your car to maintain a set speed without you having to constantly adjust the accelerator.

Now that we know how the cruise control system works, let’s take a look at some of the most common reasons why it might not be working in your car.

Cruise controls

Most Common Reasons That Cruise Control Isn’t Working

1. bad cruise control switch.

One of the first things to check if your cruise control isn’t working is the switch. This is usually located on the steering wheel or stalk. If it’s a bad switch, then it might need to be replaced.

This is usually pretty easy to check because you can just try to turn the system on and see if it engages.

In most cars, a light will illuminate somewhere on your dash (or on the button itself) once you press the switch to turn on cruise control.

So if you hit the button or switch but you don’t see a light illuminate anywhere, it could be an indication that the button or switch itself is bad. But that’s not the only reason you might not see the light turn on.

2. Blown Fuse or Relay

Another pretty common reason that cruise control might not be working is because of a blown fuse or relay.

These are usually located in the fuse box under the hood. If you think this might be the case, then you can just check the fuse box to see if there’s a blown fuse or relay.

If you don’t see a blown fuse or relay, it could still be the problem. Sometimes the fuse or relay might not look blown but could still be bad.

In this case, you might need to use a multimeter to test the fuse or relay to see if it’s still good. Typically, a relay will audibly “click” when it’s activated, so if you don’t hear the clicking noise, the cruise control relay might be bad.

3. Engine or Transmission Problems (Check Engine Light)

If the cruise control system is engaged but the car doesn’t seem to be responding, it could be because of engine or transmission problems.

These types of problems can be pretty serious, so it’s definitely something you’ll want to get checked out by an experienced mechanic or technician. Often, this will be accompanied by your check engine light turning on.

Furthermore, sometimes the cruise control system won’t even engage if there are overarching issues with the engine or transmission that would prevent it from working.

This is more commonly seen in newer cars where the electronics and computer system are so advanced and integrated that it will prevent you from using cruise until you fix the underlying issues.

4. Faulty Vehicle Speed Sensor

One of the most common reasons that cruise control might not be working is because of a faulty vehicle speed sensor. This is the sensor that tells the cruise control system how fast you’re going.

If it’s not working correctly, then the cruise control system won’t be able to maintain the correct speed.

In most cases, a faulty speed sensor will need to be replaced. However, sometimes you can clean the sensor and fix the problem. This is usually pretty easy to do and you can find instructions online or in your car’s owner’s manual.

You usually have to jack your car up and remove the wheel to get to the sensor, so make sure you’re being careful and following the owner’s manual!

5. Bad Brake Pedal Switch

Another common reason for cruise control not working is a bad brake pedal switch. This switch is located on the brake pedal itself and tells the cruise control system when you’re pressing the brakes.

If it’s not working correctly, then the cruise control system won’t know when you’re trying to stop and it could cause some serious accidents .

In most cases, you’ll need to replace the switch if it’s not working correctly. However, if you’re lucky, you might be able to clean it and get it working again.

Sometimes it can even just come unplugged and all you need to do is plug it back in. Either way, this is a pretty easy fix that you should be able to do on your own.

6. Broken Cruise Control Cable

Last up on our list of the most common reasons cruise control might not be working is a broken cruise control cable. This is the cable that runs from the cruise control module to the throttle body.

If it’s broken, then the cruise control system won’t be able to tell how much gas to give the engine and it won’t work correctly.

The vast majority of the time, you need to replace the cruise control cable if it’s broken. However, sometimes it might have just come loose or come off the track at the throttle body and you just need to reattach it correctly.

This cable has to have the correct amount of tension in order to operate properly, so you might want to leave this one up to the professionals if you aren’t confident about it!

How Hard is it to Fix Cruise Control on Your Car?

Now that you know why your cruise control might not be working, you’re probably wondering if it’s something you can handle on your own. That really depends on what the problem is.

As you can see from the list above, some of the issues are pretty easy to fix, like a blown fuse or bad brake pedal switch, while others are pretty difficult, like engine or transmission problems.

If you’re having trouble with your cruise control, the best thing to do is take it to a qualified mechanic or technician and have them diagnose the problem.

They’ll be able to tell you exactly what’s wrong and how difficult (and expensive) it will be to fix. Most of the issues with cruise control are fairly simple and inexpensive, and the convenience of the feature usually makes the repair worth it!

How Does Cruise Control Work?

Cruise control systems work by utilizing a combination of components to maintain a set speed in your vehicle. Understanding how cruise control systems function is crucial for diagnosing and troubleshooting any potential issues.

When you activate the cruise control system by pressing the ‘on’ button, it enters into a standby mode, awaiting your instructions to set the desired cruising speed. Once you have reached the desired speed, you can set it by using the control buttons typically located on the steering wheel or stalk.

Now, let’s delve into the inner workings of a cruise control system. Once the cruising speed is set, the cruise control module takes control of the throttle body , which regulates the amount of air entering the engine. By adjusting the throttle body opening, the system maintains the desired speed, compensating for changes in incline and external factors.

During operation, various sensors constantly monitor the vehicle’s speed, throttle position, and other relevant parameters. These sensors provide continuous inputs to the cruise control module, which in turn adjusts the throttle body opening accordingly to maintain the desired speed.

If you need to cancel the cruise control function, you can do so by pressing the ‘cancel’ or ‘off’ button or applying the brakes. These actions deactivate the cruise control module, allowing you to regain control of the throttle and return to normal driving mode.

It’s important to note that cruise control systems are not fully autonomous. They assist the driver in maintaining a constant speed but still require attentive driving and awareness of the road conditions. Cruise control should never be used as a substitute for actively monitoring the road ahead and reacting to unexpected situations.

Cruise Control In Cars Explained (And How To Safely Use It)

cruise control system problems

Have you ever wished you could set your car's speed and just sit back and relax while driving on a long stretch of highway? If that's the case, then cruise control is just the ticket you've been searching for—and the good news is, it's a standard feature in most cars these days!

Cruise control is a handy feature for drivers that allows you to maintain a constant speed without having to keep your foot on the gas pedal. In this post, we'll explore how cruise control works, its benefits, and how to use it safely to make your driving experience more comfortable.

Understanding Cruise Control

Cruise control, also known as speed control, is an electronic system that allows you to maintain a specific speed without manually controlling the accelerator pedal. The system uses sensors and electronic components to control the throttle and keep your car moving at a desired speed. First introduced in the late 1950s, cruise control has since become a standard feature in most modern vehicles you see on the road today.

How Does It Work?

At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed. If the car begins to slow down because of an incline (e.g. going up a hill), the system will open the throttle to accelerate. Conversely, if the car starts to speed up due to a declin (e.g. going downhill), the system will close the throttle to decelerate.

Modern cruise control systems also come with additional features like adaptive cruise control (ACC), which uses radar or cameras to detect vehicles ahead and automatically adjusts the speed to maintain a safe following distance (more on this BELOW).

The History of Cruise Control

The invention of cruise control can be traced back to the late 1940s and early 1950s, when engineer Ralph Teetor developed the first-speed control system. This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control.

Types of Cruise Control Systems

Today, drivers can choose from a range of cruise control systems, each with its own unique features and functionalities.

Conventional Cruise Control

Conventional cruise control is like your old reliable friend. It's pretty basic and doesn't have any fancy bells and whistles. You just set the speed you want, and it'll keep your car cruising along at that speed, no problem. It's perfect for those long drives on open highways, but it doesn’t automatically react to other cars on the road.

So, if the car in front of you slows down, you'll need to step in and adjust your speed manually. This trusty system comes standard on most cars and is great for saving some fuel on those long road trips .

Adaptive Cruise Control (ACC)

Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance .

It's like having an extra set of eyes on the road, making highway driving a breeze. Plus, some ACC systems can even handle stop-and-go traffic, bringing your car to a full stop and then picking up speed again when traffic gets moving.

Predictive Cruise Control

Predictive Cruise Control is like the fortune teller of cruise control systems. It uses GPS and map data to see into the future and predict what's coming up on the road, like hills or curves, and adjusts your speed accordingly. This means you get a smoother ride and better fuel efficiency, but it all depends on the quality of the GPS and map data. If that's a bit out of date, your fortune-telling cruise control might not be so accurate. It's usually found in more high-end vehicles where top-notch fuel efficiency is a focus for the engineers.

Cooperative Adaptive Cruise Control (CACC)

And then we have Cooperative Adaptive Cruise Control, or CACC. This is like the team player of cruise control systems. It allows cars to talk to each other, coordinating their speeds to maintain a safe distance. It's like having a well-coordinated team of cars all working together to make the traffic flow smoother and reduce congestion. Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. This tech is still pretty new, but it's got a lot of potential. Imagine a future where traffic jams could be a thing of the past.

Remember, these systems are here to make your drive smoother and safer, but they're not a replacement for your attention. No matter how fancy your cruise control is, these systems can be greatly influenced by external conditions like weather and traffic, and they should always be used as aids, not replacements, for attentive driving.

Common Cruise Control Symbols and Indicators

Understanding the various symbols and indicators associated with cruise control is important for safe and effective usage. These symbols typically appear on the dashboard (or on the side of the steering wheel) and may include a speedometer icon, "SET," "RES" (resume), and "CANCEL". Be sure to consult your vehicle's owner's manual for specific details and explanations of these symbols.

Benefits of Using Cruise Control

Cruise control offers several benefits to drivers, especially during long road trips or highway driving.

Fuel Efficiency

One of the main advantages of using cruise control is improved fuel efficiency. By maintaining a constant speed, cruise control helps reduce fuel consumption, leading to better gas mileage. Rapid acceleration and deceleration, on the other hand, can lead to increased fuel consumption.

Comfort and Convenience

Cruise control allows drivers to take their foot off the accelerator pedal, reducing fatigue and improving comfort during long drives. It also helps drivers avoid unintentionally exceeding the speed limit by setting a maximum speed.

When used correctly, cruise control can contribute to safer driving. By maintaining a steady speed, it reduces the likelihood of erratic driving behavior and potential accidents. However, it is important to note that cruise control shouldn't be used in certain conditions, such as heavy traffic or slippery roads .

Troubleshooting Common Cruise Control Issues

Occasionally, you may encounter issues with your cruise control systems. Common problems include cruise control not engaging or disengaging unexpectedly. Possible causes may include a faulty brake light switch, malfunctioning sensors, or issues with the control module. If you experience any problems with your cruise control, it's best to have a qualified technician diagnose and repair the issue for you.

Cruise Control and Road Etiquette

Practicing proper road etiquette while using cruise control is essential for a safe and pleasant driving experience. Here are some tips on how to use cruise control courteously:

  • Avoid using cruise control in heavy or congested traffic, as it may hinder your ability to react quickly to changing conditions.
  • Be mindful of other drivers when setting your speed. Avoid setting a speed that's significantly slower or faster than the flow of traffic.
  • If you are in the passing lane and using cruise control, be sure to adjust your speed or temporarily disengage the system to allow faster-moving vehicles to pass.
  • Always signal your intentions, such as lane changes or exiting the highway, even when using cruise control.

The Future of Cruise Control Technology

Cruise control technology plays a vital role in the development of autonomous vehicles, or self-driving cars . In autonomous vehicles, cruise control systems work together with other advanced driver assistance systems (ADAS) to enable the vehicle to operate without direct driver input. These systems include lane-keeping assist, automatic emergency braking, and collision avoidance systems.

As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. For example, some autonomous vehicles are equipped with advanced cruise control systems that can navigate complex traffic scenarios, merge onto highways, and even change lanes autonomously.

While fully autonomous vehicles are still in the developmental stages, the integration of cruise control technology is a big step toward creating safer and more efficient transportation systems.

As automotive tech continues to advance, cruise control systems are becoming more intelligent and capable. Here are some potential developments we can expect to see in the future of cruise control technology:

What Causes A Honda Adaptive Cruise Control Problem

Generally, this issue is linked with your cruise control system. But there are also other common causes that you need to be aware of. 

Here are the more common culprits behind this issue and what you can do about it.

1. Blown fuse

Fuses control all electrical components in your vehicle. Hence, if you have a blown fuse that is connected to the cruise control system, then it can most definitely fail. And if the fuse is already damaged, your cruise control system will not function at all.

The good news is that you should be able to buy and replace your blown fuse. Check the manual to learn more about the fuse connected to your cruise control system and purchase a compatible component for a replacement.

2. Faulty brake pedal switch

Another possible cause of a cruise control problem is an issue with your brake pedal. This component turns your brake lights off and on, depending on the position of your pedal. When you press on the brake pedal, this disengages the cruise control system. 

Hence, if there are issues with your brake pedal switch, this causes the cruise control system to turn off. It may also cause the brake light to get stuck in the on position, which can confuse the drivers behind you. 

3. Speed sensor problems

Your speed sensors are on every differential or wheel. These monitor your speed to determine if there is a need for traction control. Your cruise control system has the speed sensors as one of its key components. So, when there is an issue with the sensor, this may cause the cruise control to malfunction, in addition to your speedometer acting up.

You can easily tell if there is a problem with your speed sensor by checking the dashboard. When you see the check engine light or the ABS warning light turn on, it means that your speed sensor is faulty.

4. Electrical Problems

Your cruise control is electronic. There are various parts that allow the system to function. So, if there is a problem with your cruise control, you should inspect the wiring harness, as well as related connectors, that may be having issues.

The voltage source also needs to be providing ample power to your cruise control system. Small faults can contribute to defects, so you may need to check on this. Sometimes a malfunction to the clock spring, a component behind your steering wheel, can also cause the cruise control to act strange.

Use your OBD II scanner to determine any error codes linked with your cruise control that may be responsible for these issues.

5. Damaged cable or hoses

And lastly, a cruise control problem may be linked with damages to the vacuum actuator or even the cable connecting to your throttle. This is the case with older vehicles. Damages to these parts will cause the cruise control to stop working completely. 

Further Information On The Honda Adaptive Cruise Control Problem

honda adaptive cruise control problem

The cruise control initially appeared in vehicles back in the 1950s. Now, it is a staple component in modern vehicles. It is designed for maintaining a consistent speed when driving, which is useful especially in long distances.

With a cruise control, you can set your preferred speed and not have to step on your gas pedal. So, this reduces fatigue when you are driving for such a long distance. It also helps with fuel economy since you are able to maintain a steady flow of fuel.

If your cruise control system is having issues, then you need to determine what causes the failure. The repair cost depends on the affected parts and the extent of damage to the system. 

In the case of a broken brake switch or cruise control, the price can vary from $125 to as much as $350 . This includes the cost of replacement parts and labor. But if you only need to have the fuse changed, it should only cost you a few dollars. You may even replace the fuse yourself very quickly.

But if you have bigger problems with the cruise control such as a faulty actuator, the repair cost can be a bit steeper. For instance, replacing your actuator can set you back up to $700 or sometimes even more . 

While it may not appear to be an urgent fix when you have a cruise control problem, you most definitely want to get it addressed sooner than later. Otherwise, some other relevant issues affecting the performance may occur such as speedometer or acceleration problems.
