BCM Power Supply and Ground Circuit CheckEKS00I86
1. CHECK FUSES AND FUSIBLE LINK
Check 40A fusible link (letter g , located in the fuse and fusible link box).
Check 10A fuses [No. 6, 8 and 20, located in the fuse block (J/B)].
OK or NG
OK >> GO TO 2.
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
4, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK BCM POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM.
3. Check voltage between BCM connectors and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace the harness.
3. CHECK GROUND CIRCUIT
Check continuity between BCM connector M20 terminal 67 and
ground.
OK or NG
OK >> Power supply and ground circuit is OK.
NG >> Repair or replace harness.
