OPERATION
The PCM sends out a 5 Volt reference signal through PCM terminal No.30 to the Clutch Pedal Position Switch.

- With the clutch pedal DEPRESSED the 5 Volt reference signal flows through the Clutch Pedal Position Switch and returns to the PCM at a common ground at PCM terminal No.46.
- With the clutch pedal RELEASED current flow is interrupted and the PCM senses no current flow through PCM terminal No.30.
