Why Does Cruise Control Fail?
1 Answers
Causes of cruise control failure: Damaged cruise control switch, circuit malfunctions such as brake pedal sensor failure, wheel speed sensor failure, and related circuit faults, preventing the ECU from receiving signals from the cruise control solenoid valve. Solutions for cruise control failure: 1. Press the brake pedal to force the vehicle to decelerate, starting with a light press and gradually increasing pressure; 2. Utilize the transmission by forcibly shifting to neutral to slow down; 3. For vehicles with manual handbrakes, engage the handbrake one notch while rubbing against roadside barriers for friction-assisted deceleration - never use this method alone; 4. Deplete the fuel in the tank; 5. If all functions including handbrake, foot brake, engine shutdown, and gear shifting fail, drive along highway guardrails to utilize friction for stopping; 6. Turning the ignition key to shut off the engine is not recommended as it disables power steering, which may easily lead to high-speed loss of control when using this method.
