PINPOINT TEST 9: FLASH CODE 4 - CLUTCH/NEUTRAL SWITCH CIRCUIT FAILURE

Normal Operation

When the speed control actuator carries out the self-test, it checks for continuity to ground through circuit (BR/W). This is accomplished by sending a voltage reference signal to the clutch pedal position (CPP) switch (manual transaxle) or the transmission range (TR) sensor (automatic transaxle).
For manual transaxle, the clutch is applied, the signal is routed through circuit (Y/V) to the PCM and the speed control actuator. The PCM provides an internal ground.When the automatic transaxle is in NEUTRAL, the signal is routed through circuit (B/G) to ground.

Possible Causes
- Wiring, terminals or connectors
- CPP switch (manual transaxle)
- TR sensor (automatic transaxle)
- Speed control actuator
- PCM

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
