Description:

  • Cruise Control Decrease Distance Signal

Possible Symptoms:

  • Check and replace the cruise control module if faulty

  • Inspect and repair any damaged wiring or connections related to the cruise control system

  • Verify and correct any issues with the speed sensors or wheel speed sensors

  • Inspect and potentially replace the cruise control switch or buttons

Possible Causes:

  • Faulty cruise control module: The cruise control module may be malfunctioning, causing the decrease distance signal to not be properly transmitted to the vehicle.

  • Defective distance sensor: A faulty distance sensor can lead to erroneous signals being sent to the cruise control system, resulting in the decrease distance signal issue.

  • Wiring issues: Damaged or loose wiring connections between the cruise control module and the distance sensor can disrupt the signal transmission and cause the problem.

  • Faulty brake light switch: A malfunctioning brake light switch can interfere with the cruise control system's ability to receive the decrease distance signal when the brakes are engaged.

  • Problematic throttle actuator: A faulty throttle actuator may fail to respond correctly to the decrease distance signal, leading to difficulties in maintaining the desired distance while using cruise control.
