Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cruise Control Disengaged
The ECM disengages the cruise control operation based on the signals from the following switches:
- The on/off switch
- The clutch start switch
- The cruise/brake switch
- The stoplamp switch
The cruise/brake switch, the clutch start switch, and the stoplamp switch are used to disengage the cruise control system. The stop lamp and cruise/brake switch are incorporated into an assembly and are mounted to the brake pedal bracket. When the brake pedal is pressed, the normally closed cruise/brake switch opens and the normally open stoplamp switch closes. The ECM detects a low signal voltage on the cruise/brake signal circuit and detects a high signal voltage on the stoplamp switch signal circuit. When the clutch pedal is pressed, the normally closed clutch start switch opens and the ECM detects a low signal voltage on the clutch start switch signal circuit. The cruise control system will disengage when the cruise control on/off switch is switched to Off. The vehicle speed stored in the memory of the ECM will be erased when the cruise control on/off switch is turned Off, or the ignition switch is turned off.
The cruise control system will disengage when the ECM detects that a driver override function has been active for approximately 60 seconds.
