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