WARNING: This page is about a different car, the 1996 Eagle Vision, 1996 Dodge Intrepid, and 1996 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For connector terminal idnetification, see CONNECTOR IDENTIFICATION DIRECTORY table. For wiring diagram, see WIRING DIAGRAMS article.

Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for damaged or pushed out terminals. Repair as necessary. Perform TEST VER-2A . If PCM connector terminals are okay, go to next step.
NOTE: For next step, see the IAC DRIVER IDENTIFICATION table for IAC motor wire color identification.
Using an external ohmmeter, check resistance of IAC motor driver No. 1 wire between IAC motor connector and PCM connector terminal No. 57. If resistance is 5 ohms or more, repair open in IAC motor driver No. 1 wire. Perform TEST VER-2A . If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A .
