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





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

Normal Operation

The clutch pedal position (CPP) switch, normally closed, supplies a ground signal to the powertrain control module (PCM) through circuit 306 (TN/LB). When the clutch pedal is applied, the CPP switch moves to the open position causing the PCM to lose the ground signal and deactivate the speed control. Ground for the CPP is supplied by circuit 570 (BK/WH).

Possible Causes
- Circuit 306 (TN/LB) short to ground
- CPP switch
- PCM
