How do I know if my cruise control module is bad?
If your vehicle's cruise control system is not functioning properly, it could be a sign that the cruise control module is faulty. The cruise control module is a critical component that manages the cruise control system, and a malfunctioning module can cause various issues with the cruise control's operation. In this article, we'll explore the signs of a bad cruise control module and provide guidance on how to diagnose and address the problem.
Symptoms of a Bad Cruise Control Module
Here are some common signs that your cruise control module may be malfunctioning:
- Cruise control not engaging: If the cruise control system fails to activate when you try to engage it, it could indicate a problem with the cruise control module.
- Cruise control disengaging unexpectedly: If the cruise control system disengages on its own while driving, it may be a sign of a faulty cruise control module.
- Cruise control not maintaining speed: If the cruise control system is unable to maintain a consistent speed, it could be a result of a malfunctioning cruise control module.
- Cruise control warning light illuminated: Many vehicles have a dedicated warning light for the cruise control system, and if this light is illuminated, it may indicate an issue with the cruise control module.
If you experience any of these symptoms, it's essential to have your vehicle's cruise control system diagnosed by a qualified mechanic to determine the root cause of the problem.
Diagnosing a Bad Cruise Control Module
To diagnose a bad cruise control module, a mechanic will typically follow these steps:
- Scan for diagnostic trouble codes: The mechanic will use a diagnostic tool to scan the vehicle's computer system for any stored trouble codes related to the cruise control system. These codes can provide valuable information about the specific issue with the cruise control module.
- Perform a visual inspection: The mechanic will visually inspect the cruise control module and its associated wiring and connections to check for any signs of damage or wear.
- Test the cruise control module: The mechanic may use a multimeter or other diagnostic equipment to test the cruise control module's electrical signals and functionality to determine if it is the source of the problem.
If the diagnosis confirms that the cruise control module is faulty, the next step would be to replace the module with a new one to restore the proper operation of the cruise control system.
Replacing a Bad Cruise Control Module
Replacing a cruise control module can be a relatively straightforward process, but it's important to ensure that the replacement module is compatible with your vehicle's make, model, and year. The mechanic will typically follow these steps to replace the cruise control module:
- Disconnect the battery: To prevent any electrical issues during the replacement process, the mechanic will disconnect the vehicle's battery.
- Remove the old cruise control module: The mechanic will locate the cruise control module, typically under the dashboard or in the engine compartment, and disconnect it from the wiring harness.
- Install the new cruise control module: The mechanic will then install the new cruise control module, reconnect the wiring harness, and secure the module in its proper location.
- Reconnect the battery: Finally, the mechanic will reconnect the vehicle's battery and test the cruise control system to ensure it is functioning correctly.
By following these steps, the mechanic can effectively replace a faulty cruise control module and restore the proper operation of your vehicle's cruise control system.

What is the most common failure of a cruise control system?
6 of the Most Common Reasons Your Cruise Control Isn't Working
- Issues with the Speed Sensor.
- Issues with the Computer.
- Physical Damage to Components.
- See if You Have a Malfunctioning Brake Pedal Switch.
- Blown Fuse.
- Dirty or Malfunctioning Cameras (Adaptive Cruise Control)
How do you fix cruise control malfunction?
If your cruise control system is electronically controlled, it will have an associated fuse. If there's an electrical problem, the fuse will fail in order to keep other wiring from getting damaged. Try replacing the fuse. If it solves the problem and the cruise control keeps working, that's great!
What does a cruise control module do?
Instead, they contain a wireless system that communicates with the internal computer. The car's computer identifies the vehicle's speed and the cruise control module maintains the existing speed. The best time to utilize your cruise control feature is on highways where speed limits range from 55 to 75 miles per hour.
What sensor affects cruise control?
Your vehicle relies on speed sensors to provide data to the cruise control system. If the speed sensors are malfunctioning or not providing accurate information, your cruise control may not engage properly. Speed sensors can wear out over time or become dirty. Cleaning or replacing them may resolve the issue.
Where is the cruise control sensor located?
The Adaptive Cruise Control camera is located behind the windshield in front of the rearview mirror. It's important to keep the windshield clean for the camera to work properly. On some vehicles, the feature also uses radar sensors located in the front grille or bumper. Keep these areas of the vehicle clean.
How do I know if my cruise control is bad?
When you've set the cruise control, it should always maintain the speed you've set. If you notice that your speed fluctuates after setting it, your system may be malfunctioning. To determine if you have a problem, try resetting the system. To do this, turn the cruise control off by disengaging the switch in your car.
Is there a fuse that controls cruise control?
Since your car's cruise control is part of an electrical system, it needs a fuse to function properly. A short circuit in this system can cause a fuse to blow, which means that the cruise control will suddenly stop working. Fortunately, replacing a blown fuse is a cheap and easy repair for any auto mechanic.
