Test 7F - Short To Battery
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagram, see WIRING DIAGRAMS
article in this section.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Using an external ohmmeter, check resistance between BCM Blue connector terminals No. 14, CCD BUS positive circuit (Violet/Brown wire), and No. 19, key-in light driver circuit (Yellow/Red wire). If resistance is less than 5 ohms, repair Violet/Brown wire shorted to Yellow/Red wire. Perform TEST VER-1 .
- If resistance is more than 5 ohms, check resistance between Blue BCM connector terminals No. 15, CCD BUS negative circuit (White/Black wire), and No. 19, key-in light driver circuit (Yellow/Red wire). If resistance is less than 5 ohms, repair White/Black wire shorted to Yellow/Red wire. Perform 6TEST VER-1 .
- If resistance is more than 5 ohms, check resistance between Blue BCM connector terminals No. 14, CCD BUS positive circuit (Violet/Brown wire), and No. 21, seat belt light output circuit (Dark Blue/Red wire). If resistance is less than 5 ohms, repair Violet/Brown shorted to Dark Blue/Red wires. Perform TEST VER-1 .
- If resistance is more than 5 ohms, check resistance between Blue BCM connector terminals No. 15, CCD BUS negative circuit (White/Black wire), and No. 21, seat belt light driver circuit (Dark Blue/Red wire). If resistance is less than 5 ohms, repair White/Black shorted to Dark Blue/Red wires. Perform TEST VER-1 .
- If resistance is more than 5 ohms, use DRB in ohmmeter mode to check resistance between BCM case and ground. If resistance is more than 5 ohms, repair BCM case ground. Perform TEST VER-1 .
- If resistance is less than 5 ohms, check resistance of Blue BCM connector terminal No. 13, ground circuit (Black/Light Green wire). If resistance is more than 15 ohms, repair open Black/Light Green wire. Perform TEST VER-1 . If resistance is less than 15 ohms, replace BCM. Perform TEST VER-1 .
