- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for damaged or pushed out terminals. Repair as necessary. Perform TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES . If PCM connector terminals are okay, go to next step.NOTE: For next step, see IAC DRIVER CIRCUIT ID table for IAC motor connector wire color identification and PCM CONNECTOR WIRE IDENTIFICATION table.
- Using an ohmmeter, check resistance of IAC motor driver No. 2 circuit between IAC motor connector and PCM connector terminal No. 49. If resistance is 5 ohms or more, repair open in IAC motor driver No. 2 circuit. Perform TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES . If resistance is less than 5 ohms, replace PCM. Perform TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES .
