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 powertrain control module (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.

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