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.
Before proceeding with diagnosis, the following precautions must be observed:
- When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION section before disconnecting battery.
- Vehicle must have a fully charged battery and functional charging system.
- Probe PCM connector from pin side. DO NOT backprobe PCM connector.
- DO NOT cause short circuits when performing electrical tests. This will set additional trouble codes, making diagnosis of original problem more difficult.
- DO NOT use a test light instead of a voltmeter.
- Always repair lowest trouble code number (CHECK ENGINE light) or first trouble code message displayed (DRB) before repairing other codes.
- Always perform VERIFICATION TEST SC-VER after repairs are made.
- Always disconnect DRB after use.
- Always disconnect DRB before charging battery.
