Test 8H - Bus Short To 5 Volts
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see appropriate article in ENGINE PERFORMANCE:
- WIRING DIAGRAMS - 3.3L
- WIRING DIAGRAMS - 3.5L
- After each repair, perform TEST VER-1.CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Using an external ohmmeter, check resistance between Body Control Module (BCM) Bone connector terminal No. 8 (Violet/Brown wire) and BCM Gray connector terminal No. 13 (Light Green/Black wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Light Green/Black wires.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 7 (White/Black wire) and BCM Gray connector terminal No. 13 (Light Green/Black wire). If resistance is less than 5 ohms, repair short between White/Black and Light Green/Black wires.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 8 (Violet/Brown wire) and BCM Gray connector terminal No. 5 (Light Green/Red wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Light Green/Red wires.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminal No. 7 (White/Black wire) and BCM Gray connector terminal No. 5 (Light Green/Red wire). If resistance is less than 5 ohms, repair short between White/Black and Light Green/Red wires.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminals No. 8 (Violet/Brown wire) and No. 20 (Light Blue wire). If resistance is less than 5 ohms, repair short between Violet/Brown and Light Blue wires.
- If resistance is more than 5 ohms, check resistance between BCM Bone connector terminals No. 7 (White/Black wire) and No. 20 (Light Blue wire). If resistance is less than 5 ohms, repair short between White/Black and Light Blue wires. If resistance is more than 5 ohms, replace BCM.
