- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connector for damaged, pushed-out or miswired terminals. Repair as necessary. Perform TEST VER-2. If connector is okay, go to next step.
- Using an external ohmmeter, check resistance of Idle Air Control (IAC) motor driver No. 3 circuit (Gray/Red wire) between IAC motor connector and PCM terminal No. 39. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2. If resistance is more than 5 ohms, repair open Gray/Red wire. Perform TEST VER-2.
