WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, 1995 Dodge Caravan, and 1995 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Check connector, and clean and repair as necessary. Ensure gear selector is in Drive. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 30, Park/Neutral (P/N) position switch sense circuit (Black/Orange wire).
- If resistance is greater than 5 ohms, replace PCM. Perform TEST SC-VER . If resistance is less than 5 ohms, disconnect P/N position switch connector. Check connector, and clean and repair as necessary. Perform TEST SC-VER .
- If connector is okay, check resistance of PCM connector terminal No. 30, P/N switch sense circuit (Black/Orange wire). If resistance is greater than 5 ohms, replace P/N position switch. Perform TEST SC-VER . If resistance is less than 5 ohms, repair short to ground in Black/Orange wire. Perform TEST SC-VER .
