Normal Operation
The powertrain control module (PCM) sends a signal through circuit 848 (DG/OG) to the speed control switches which passes through the clockspring. The return signal is sent through circuit 151 (LB/BK) and the clockspring.
Possible Causes
- Parking brake switch circuitry
- Speed control switch
- Digital transmission range (TR) sensor
- Vehicle speed signal
- PCM
