WARNING: This page is about a different car, the 1995 Dodge Ram Wagon, 1995 Dodge Ram Van, 1995 Dodge Pickup, 1995 Dodge Dakota, and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS section at the end of this article.

Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connectors for damaged, pushed-out or miswired terminals. Repair as required. Perform TEST VER-1. If PCM terminals are okay, go to next step.
Using an external ohmmeter, check resistance of driver No. 4 circuit (Violet/Black wire) between IAC motor connector and PCM connector terminal No. 59. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-1. If resistance is more than 5 ohms, repair open Violet/Black or Gray/Red wire. Perform TEST VER-1.
