  1. Remove driver's front door inner trim panel. Disconnect Driver's Door Module (DDM) C1 connector. Using DVOM, measure resistance between ground and DDM C1 connector terminal No. 5 (Orange/Black wire). See Figure . If resistance is 20 ohms or greater, go to next step. If resistance is less than 20 ohms, repair short to ground in Orange/Black wire. Perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
