- 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.
