Test C: Speed Control Switch Stuck Or Circuit Failure

PINPOINT TEST C: SPEED CONTROL SWITCH STUCK OR CIRCUIT FAILURE

Normal Operation
The PCM sends a signal through circuit 151 (LB/BK) to the speed control switches, which passes through the clockspring. The return signal is sent through circuit 848 (DG/OG) and the clockspring.

- Wiring, terminals, or connectors
- Clockspring
- Speed control switch
