The normally closed clutch pedal position (CPP) switch detects when the clutch pedal is pressed (manual transmissions) to disable the speed control system and PTO and raised-idle mode. Switch actuation occurs as the clutch is initially pressed prior to disengaging the transmission at the top of travel.
CAUTION:
The powertrain control module (PCM) harness connectors must be properly seated and the connector latch properly attached to eliminate possible driveability concerns or a no start condition. Installing PCM connectors on an angle may cause an improper connection, misdiagnosis and damaged components. Install the connector until the lever pivots and seats itself. Apply light pressure to get the connector into position on the PCM and then fully seat the connector.
NOTE:
Visually inspect the harness connectors for corrosion, damage, proper mating and correct pin tension.
NOTE:
When the PCM is disconnected additional DTCs will be set. Clear all DTCs after restoring the vehicle.
