- After each repair, perform TEST VER-1.
- Using an external ohmmeter, check resistance between Body Control Module (BCM) Gray connector terminal No. 6 (Tan wire) and BCM Bone connector terminal No. 8 (Violet/Brown wire). If resistance is less than 5 ohms, repair short between Tan wire and Violet/Brown wire.
- If resistance is more than 5 ohms, check resistance between BCM Gray connector terminal No. 6 (Tan wire) and BCM Bone connector terminal No. 7 (White/Black wire). If resistance is less than 5 ohms, repair short between Tan wire and White/Black wire.
- If resistance is more than 5 ohms, check resistance between BCM Gray connector terminal No. 3 (Tan/Red wire) and BCM Bone connector terminal No. 8 (Violet/Brown wire). If resistance is less than 5 ohms, repair short between Tan/Red wire and Violet/Brown wire.
- If resistance is more than 5 ohms, check resistance between BCM Gray connector terminal No. 3 (Tan/Red wire) and BCM Bone connector terminal No. 7 (White/Black wire). If resistance is less than 5 ohms, repair short between Tan/Red wire and White/Black wire.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminals No. 5 (Yellow/Red wire) and No. 8 (Violet/Brown wire). If resistance is less than 5 ohms, repair short between Yellow/Red wire and Violet/Brown wire.
- If resistance is more than 5 ohms, check resistance between BCM bone connector terminals No. 5 (Yellow/Red wire) and No. 7 (White/Black wire). If resistance is less than 5 ohms, repair short between Yellow/Red wire and White/Black wire.
- If resistance is more than 5 ohms, using scan tool in ohmmeter mode, check resistance of BCM Bone connector terminal No. 21 (Black wire). If resistance is more than 5 ohms, repair open Black/Light Green wire.
- If resistance is less than 5 ohms, check resistance of BCM bone connector terminal No. 14 (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, replace BCM.
