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

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.

Final Thoughts

Your cruise control includes a fuse, which may sometimes break and cause the system to fail. In the same way, there is a brake switch that also impacts the performance of your cruise control system. This sends signal to the system, which activates it when you apply the brakes. Thus, it is aware of when accelerating should cease. 

When your check engine light is turned on, this disables the cruise control system’s function. This is designed for safety purposes. So it is best to get your Honda Adaptive cruise control problem fixed sooner than later. By doing so, you can prevent performance issues and make sure no further damages occur over time.

  1. What if along with the adaptive cruise control failing, the road mitigation departure as well as brake system light also turns on?

    • Hi Tom,

      If the adaptive cruise control (ACC) fails and you also notice the road mitigation departure and brake system lights turning on, it could indicate a more significant issue with your vehicle’s safety systems. In this case, it is recommended to take the following steps:

      1. Check the Owner’s Manual: Refer to your vehicle’s owner’s manual to understand the specific meaning of these warning lights. It may provide you with specific instructions or information about the problem.

      2. Inspection: Take your vehicle to an authorized Honda service center or a qualified mechanic for a comprehensive inspection. They will be able to diagnose the issue using specialized diagnostic equipment and software.

      3. System Reset: Sometimes, a temporary glitch or error in the system can cause multiple warning lights to illuminate. Try performing a system reset by disconnecting the vehicle’s battery for a few minutes and then reconnecting it. This may clear the fault codes and reset the systems. However, keep in mind that this is a temporary solution, and the underlying issue needs to be addressed.

      4. Addressing Faulty Components: Depending on the diagnosis, the faulty components related to the ACC, road mitigation departure, and brake system will need to be repaired or replaced. This could involve issues with sensors, wiring, actuators, or control modules. Only a qualified technician can accurately identify and resolve these problems.

      It is crucial to address these issues promptly, as they directly affect the safety and functionality of your vehicle’s advanced driver assistance systems. Following the manufacturer’s recommendations and seeking professional assistance is the best course of action in such situations.
