What to do if you have a hole in your cruise control?
A cruise control mechanism has a vacuum powered actuator connected to the control module by vacuum lines. Check for holes in the vacuum line of your cruise control by starting the engine and opening the car hood. Listen for signs of vacuum leaks.
What causes a cruise control to stop working?
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.
Can a brake light disengage cruise control?
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.
Where is the cruise control located on a car?
The throttle and the actuator mechanism are normally found at the throttle valve assembly on top of engine. Check if the metal chains connecting the actuator and the throttle have broken away. You can easily solve this cruise control problem by replacing the throttle linkage.

How can I troubleshoot my Jaguar cruise control?
First, inspect the sensor on the black wire for a ground signal from the module. Then, make sure the brown wire has a pulsed voltage on it when spinning the wheel. Finally, check the ring on the rear axle for any looseness or damage. What can prevent a Jaguar cruise control from working when the ‘Fail Safe Motor Mode’ orange light is on?
How does an adaptive cruise control system work?
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.
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.
