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.
Normal Operation
The speed control actuator sends a signal through circuit VES10 (WH) to the speed control switches, which passes through the clockspring. The return signal is sent back through the clockspring to circuit RES08 (GN/BN). When 2 buttons are pressed simultaneously, the speed control system enters a stand-by mode.
This pinpoint test is intended to diagnose the following:
