PA4 - Check Spout For Short to VREF, Ground and PIP
- Key "OFF".
- Breakout box installed, Powertrain Control Module (PCM) disconnected.
- Ignition Control Module (ICM) disconnected.
For Short to VREF:
- Measure resistance between test pin 36 and test pin 26 at the breakout box. For Short to Ground:
- Measure resistance between test pin 36 and test pins 16, 20, 40, 46 and 60 at the breakout box.
For Short to Profile Ignition Pickup (PIP):
- Measure resistance between test pin 36 and test pin 56 at the breakout box.
- Is each resistance greater than 10,000 ohms?
Yes -- Reconnect all components. Go to Ignition Systems.
No -- Service short circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
