- Turn ignition off. Disconnect Body Controller Module (BCM) Bone connector. Module is located behind right kick panel. With DRB-II in voltmeter mode, check voltage on BCM Bone connector terminal No. 19, fused battery feed circuit (Pink wire). If voltage is less than 10 volts, repair open circuit in Pink wire back to fuse/junction block. Perform VERIFICATION PROCEDURE VER-1.
- If voltage is more than 10 volts, use DRB-II in ohmmeter mode to check resistance on BCM Bone connector terminal No. 21, ground circuit (Black wire). If resistance is more than 5 ohms, repair open circuit in Black (ground) wire. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, use DRB-II in ohmmeter mode to check resistance on BCM Bone connector terminal No. 14, signal ground circuit (Black/Light Green wire). If resistance is more than 100 ohms, repair open circuit in Black/Light Green wire to BCM. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 100 ohms, turn ignition on. With DRB-II in voltmeter mode, check voltage of Violet/Brown wire on BCM Bone connector terminal No. 8, Chrysler Collision Detection (CCD) bus (-) circuit. If voltage is less than one volt, repair open circuit in Violet/Brown wire to BCM. Perform VERIFICATION PROCEDURE VER-1.
- If voltage is more than one volt, use DRB-II in voltmeter mode to check voltage of White/Black wire on BCM Bone connector terminal No. 7, CCD bus (-) circuit. If voltage is less than one volt, repair open circuit in White/Black wire to BCM. Perform VERIFICATION PROCEDURE VER-1. If voltage is more than one volt, replace BCM. Perform VERIFICATION PROCEDURE VER-1.
