Diagnostic trouble code P0567 indicates a malfunction with the cruise control resume signal in your vehicle. The cruise control resume signal is a signal sent to the powertrain control module (PCM) when the driver wants to resume the cruise control function.
Here are the steps to diagnose and fix the problem:
Check the cruise control switch: The cruise control switch is located on the steering wheel. Check to make sure the switch is functioning properly and not stuck in the on position.
Check the cruise control fuse: The cruise control system has a dedicated fuse. Check the fuse to make sure it is not blown.
Inspect the cruise control wiring: Inspect the wiring and connectors for any signs of damage or corrosion. Repair or replace any damaged components.
Check the brake switch: The brake switch is used to disengage the cruise control system when the brake pedal is pressed. Test the switch to make sure it is functioning properly.
Check the clutch switch: If your vehicle is equipped with a manual transmission, the clutch switch is used to disengage the cruise control system when the clutch pedal is depressed. Test the switch to make sure it is functioning properly.
Inspect the cruise control servo: The cruise control servo is responsible for adjusting the throttle position to maintain a constant vehicle speed. Inspect the servo to make sure it is functioning properly.
Check the PCM: If all the above components are functioning properly, it is possible that the problem is with the PCM. Test the PCM to make sure it is functioning correctly.
Reset the Check Engine Light: After repairing the problem, reset the Check Engine Light using an OBD-II scanner.
If you are not confident in your ability to diagnose and fix the problem, it is recommended that you take your vehicle to a qualified mechanic or dealership for repair. A certified technician will have the expertise and diagnostic tools necessary to properly diagnose and fix the issue.
