Service Precautions

WARNING: This page is about a different car, the 1995 Dodge Ram Wagon and 1995 Dodge Ram Van. 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 before disconnecting battery.
Vehicle must have a fully charged battery and functional charging system.
Probe PCM 60-pin connector from pin side. DO NOT backprobe PCM connector.
DO NOT cause short circuits when performing electrical tests. This will set additional fault codes, making diagnosis of original problem more difficult.
DO NOT use a test light instead of a voltmeter.
Always repair lowest fault code number (CHECK ENGINE light) or first fault message displayed (DRB) before repairing others.
Always perform VERIFICATION TEST SC-VER after repairs are made.
Always disconnect DRB after use.
Always disconnect DRB before charging battery.
