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.
Principles of Operation
The stoplamp switch is normally open. When the brake pedal is applied with the speed control system engaged, the stoplamp switch closes (to battery voltage), putting the speed control in the stand-by mode.
The clockspring provides the electrical interface between the steering column wiring and the speed control switches in the steering wheel.
The inputs to the speed control actuator required to operate the speed control system are the:
- Speed control switches
- Digital transmission range (TR) sensor (automatic transaxle)
- Clutch pedal position (CPP) sensor (manual transaxle)
- Stoplamp switch
- Speed control deactivator switch
- Speed signal from the anti-lock brake system (ABS) module
