Preliminary CheckNKS003T6
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES AND FUSIBLE LINK
Check for blown fuses and fusible link.
Refer to LT-273, "Wiring Diagram — ROOM/L —" .
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
OK or NG
OK >> INSPECTION END
NG >> Repair harness or connector.
