Test D: The Speed Control Does Not Disengage When The Clutch Is Applied

PINPOINT TEST D: THE SPEED CONTROL DOES NOT DISENGAGE WHEN THE CLUTCH IS APPLIED

Normal Operation
The speed control actuator sends a voltage reference signal through circuit CET21 (GN/WH). When the clutch is applied, the clutch pedal position (CPP) switch closes and routes the signal to ground through circuit RE407 (YE/VT). Ground is supplied by the PCM.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Obstructions to the accelerator pedal or linkage
- Speed control actuator
- CPP switch
- Speed control cable
- Accelerator cable
- PCM
