Self-Diagnostic System: Precautions

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2000 Plymouth Neon, 2000 Plymouth Breeze, 2000 Dodge Stratus, 2000 Dodge Neon, and 2000 Dodge Intrepid. However, it is still accessible from the selected car via links, so may be relevant.

Before proceeding with diagnosis, observe following precautions:

Ensure battery is fully charged.
Probe PCM connector from pin side. DO NOT backprobe PCM connector or probe wires through insulation.
DO NOT cause short circuits when performing electrical tests. This will set additional DTCs, making diagnosis of original problem more difficult.
DO NOT use a test light in place of a voltmeter.
Always begin repair with lowest DTC number (MIL) or first DTC displayed (scan tool).
Always perform verification test after repairs are made.
Always disconnect scan tool after use.
Always disconnect scan tool before charging battery.
