TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2005 July 2005 FX
2. CHECK POWER SUPPLY CIRCUIT (BATTERY)
Make sure voltage between BCM harness connector M4 terminals 42 (GY), 55 (R) and ground.
OK or NG
OK >> GO TO 3.
NG >> Check BCM power supply circuit for open or short.
3. CHECK POWER SUPPLY CIRCUIT (IGN)
1. Turn ignition switch ON.
2. Make sure voltage between BCM harness connector M3 terminal 38 (W/L) and ground.
OK or NG
OK >> GO TO 4.
NG >> Check BCM power supply circuit for open or short.
4. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector M4 terminal 49(B), 52 (B) and ground.
OK or NG
OK >> Replace BCM. Refer to BCS-16, "Removal and Installa-
tion of BCM" .
NG >> Repair or replace BCM ground circuit. Te r m i n a l
