TA17 - Check PNP Circuit Continuity
- Key "OFF".
- Breakout box installed, Powertrain Control Module (PCM) disconnected.
- Disconnect Park Neutral Position (PNP) switch (3 pin at transmission).
Testing Schematic:
- Measure resistance between test pin 30 at the breakout box and PNP/IGN Start circuit at PNP switch vehicle harness connector.
- Is resistance less than 5.0 ohms?
Yes -- Replace PCM. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
No -- Service open between PCM and PNP circuit connection to Start circuit. Remove breakout box. Reconnect all components. Rerun quick test. Quick Test Appendix (Detailed Testing Instructions)
