WARNING: This page is about a different car, the 1998 Dodge Intrepid and 1998 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST 1B: IDENTIFYING ATC SYSTEM BCM DIAGNOSTIC TROUBLE CODES before proceeding with this test. DTC 40 will set if BCM detects mode door drive output shorted to ground.
- Locate Body Control Module (BCM), attached to junction block, at left end of instrument panel. Turn ignition off. Disconnect BCM Gray 14-pin connector (C1). Ensure connector terminals are clean and tight. Repair as necessary.
- Turn ignition off. Close all doors and ensure courtesy lights are off. Using an ohmmeter, measure resistance between ground and BCM connector C1 terminal No. 9 (Dark Green/Yellow wire). If resistance is less than 5.0 ohms, repair short to ground in Dark Green/Yellow wire. If resistance is more than 5.0 ohms, replace BCM. Perform VERIFICATION TEST .
