Perform this test when directed by QUICK TEST. This test is only intended to diagnose the following components and circuits:
- Clutch Pedal Position (CPP) Switch
- Powertrain Control Module (PCM)
- Neutral Start Switch (F650-750 W/Allison AT545)
- Wiring Harness Circuits (CPP & SIG RTN)
- Clutch Pedal Position Switch
Is a normally closed switch that detects when clutch pedal is depressed (manual transmissions) to disable speed control system and PTO, and raised-idle mode. CPP switch actuation occurs as clutch is initially depressed prior to disengaging transmission at top of travel. - Neutral Start Switch
Is a normally closed switch that is used by PCM to enable raised-idle modes and Auxiliary Powertrain Control Module (APCM) functions.
