article in ENGINE PERFORMANCE. Perform TEST VER-1 after each repair.
- Disconnect Body Control Module (BCM) Black connector. Check, clean and repair connections as needed. Using scan tool in ohmmeter mode, check resistance of BCM Black connector terminal No. 3 (Yellow/Black wire). If resistance is more than 5 ohms, replace BCM. If resistance is less than 5 ohms, go to next step.
- Disconnect left pod switch assembly connector. See Figure. Check, clean and repair connections as needed. If resistance is more than 5 ohms, replace dimmer switch, located in left pod switch. If resistance is less than 5 ohms, go to next step.
- Disconnect radio connector. Check, clean and repair connections as needed. If resistance is more than 5 ohms, replace radio. If resistance is less than 5 ohms, go to next step.
- Disconnect Automatic Temperature Control (ATC) head (located behind A/C-heater control panel), if equipped. Check, clean and repair connections as needed. If resistance is more than 5 ohms, replace ATC head. If resistance is less than 5 ohms, repair Yellow/Black wire between BCM Black connector and dimmer switch connector for short to ground.
