5 Reasons Why Your Cruise Control Stopped Working

• Updated: March 15, 2023

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

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!

View all Citroen C4 Problems

Cruise control

This driving assistance function allows you to drive at the speed of your choice without the need to action the accelerator. This system is available above 40 km/h (25 mph), with 4th gear or higher on a manual gearbox or 2nd gear or higher on an automatic gearbox.

Note: Information relating to the cruise control is displayed in zone A of the instrument panel.

To select the function

Turn control 1 to position "REG".

To select a cruising speed

At the time you select the function via the control 1, there is no cruise speed previously memorised:

Accelerate to the desired speed, then press button 2 or button 4. The cruise speed will then be memorised and displayed in zone A on the instrument panel.

You can then release the accelerator pedal. The vehicle will automatically keep to that chosen speed.

Note: The vehicle speed may vary slightly from that memorised.

Adjustment of the memorised speed while cruise control is in operation

To adjust the memorised speed, displayed in zone A, press on:

- button 4 to increase the speed, - button 2 to decrease the speed.

Note: you can use successive presses to modify the cruise speed in steps of 1 mph and a continuous press to jump in steps of 5 mph.

To exceed the cruise speed temporarily

While cruise control is in use, it is always possible to go above the cruise speed simply by pressing the accelerator pedal (for example to overtake another vehicle). The speed displayed in zone A flashes. You have only to release the accelator pedal to return to your cruise speed.

Note: if during cruise control the system cannot keep to the cruise speed (e.g. on a steep descent), then the speed flashes. If necessary, brake to curb your speed.

Deactivation of cruise control with memorised speed

- Either by pressing the brake pedal or the clutch pedal. - Or with a press on button 3. - Or when ESP or ASR is active.

Note: cruise control is disengaged when the gear lever is in neutral position. These actions bring up the display "OFF" in zone A in the instrument panel. These actions do not cancel your cruise speed which remains displayed on the instrument panel.

Reactivation of cruise control

- by recalling the memorised speed:

Following a deactivation, press on button 3. Your vehicle automatically resumes the memorised cruise speed displayed in zone A.

- by selecting the current speed:

Press on button 2 or 4 as soon as the desired speed is reached. The information "OFF" will then disappear from zone A.

To cancel the function

- by moving the control from position "REG" to position 0. - by stopping the engine.

The cruise speed chosen previously is no longer memorised.

In the event of a malfunction, a message is displayed, accompanied by a sound signal and lighting of the SERVICE warning lamp. Consult your CITROËN dealer.

Cruise control must only be used where road conditions permit driving at a constant speed. Do not use it on congested roads or when weather and road conditions are poor. The driver must still remain attentive and in complete control of the vehicle. You are recommended to keep your feet within range of the pedals. To avoid any interference with the pedals:

- ensure that any over-mats are correctly fitted, - never superimpose one overmat on another.

cruise control

Hi Does anybody else have problems with cruise control and speed limiter which can not be turned ON or falling out sometimes:?: Sometimes I can not turn on cruise control to matter what I do, can only turn it on when I had the ignition off , Citroën Denmark can not find the error, they expect that this is something communication goes wrong, the car has been at a workshop all most once every week since we got the car 8/7 2016  

Mine both work perfectly.  

Just a thought, but your situation reminded me of a similar problem I had with my C5 a few years ago. It turned out to be a sticky micro-switch on the clutch pedal. What I found was that if I put my toe behind the clutch pedal and lifted it up the cruise control would activate. The more permanent solution was to give the micro-switch a squirt with WD40 and I didn't experience any further issues  

Thanks DavidP, but I have no clutch pedal, My Cactus is a 100 BlueHDI S & S ETG6 CoolComfort. and my car have a new brake micro-switch :-(  

If the brake microswitch is faulty, it could be cancelling the cruise control....

I was coming into motorway road works with a 50 MPH limit and went to set the Cruise Control but couldn't. Nothing was coming onto the dashboard despite turning the thumb wheel. I was a bit surprised! However, the car was in neutral as I was "coasting" into the road works. When I engaged a gear Cruise Control was fine. The technology in the cars is a bit or a surprise, clearly it is checking lots of parameters before allowing cruise to be enabled. I appreciate your car is auto, but am sure the basics are the same, your car is busy checking many variables before enabling cruise. Hope they track it down.... K

Think that the ETG version has a little more intelligence, when joining a clear motorway I will tend to set the cruise control speed on pause to 70 then once I am happy that the road is clear engage it, the car will then accelerate up from the speed that I am doing with gear changes as necessary.  

Have now got a new gear shift computer, about 14 days ago, has not had any problems since.  

On a previous C4 with ETG I had a cruise control error that was fixed by replacing the brake pedal micro switch. Also once the stalk control got some dirt in it and was fixed by WD40. I hope they manage to trace it for you.

problem for activating cruise control

Don't mess around take it in to get fixed under warranty its a 2021 car and your car is not reporting a ACC Fault  

Attachments

Thank you. It's very annoying. As you told there are not any ACC Fault report but I can not activate it. I guessed there might be settings that I didn't realize.  

It would be interesting to hear what the fault is. I have a 297 and something similar keeps on happening. To fix mine I switch the car of Remove the stalk, switch the ignition on and off and then replace the stalk. After that it works fine for a while, so I would love to know what Peugeot say is wrong with yours.  

I have an appointment on the 12 May and I'll let you know the result.  

Unfortunately, it does not work on dry roads too. it doesn't work at all. I takeed an appointment on the 12th of May and I hope this problem will be solved easily. I will write the result here.  

Yes, I tried many times  

Don't mess around take it in to get fixed under warranty its a 2021 car and your car is not reporting a ACC Fault Nox Vidmate VLC ​

VAN/CAN appeared on the Picasso around 2002.
