TA2 - Check PNP/CPP Input
- Key "OFF".
- Verify A/C is "OFF", if so equipped.
- Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.
- Install breakout box, leave PCM disconnected.
Testing Schematic:
- Measure resistance between test pin 30 and test pin 46 at the breakout box:
1. With transmission in "Neutral" and the clutch pedal "UP".
2. With transmission in "GEAR" and the clutch pedal "DOWN".
- Is each resistance less than 5.0 ohms?
Yes -- Go to TA3. TA3 - Check CPP/PNP Switch Integrity
No -- Go to TA5. TA5 - Check PNP/CPP Switch
