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


D1-D3:






Normal Operation
Vehicles equipped with a manual transmission have an additional clutch pedal position (CPP) switch. The CPP switch, normally closed, supplies a ground signal to the PCM through circuit 306 (TN/LB). When the clutch pedal is pressed, the CPP switch moves to the open position, causing the PCM to lose the ground signal and deactivate the speed control.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- CPP switch
- PCM
