Preliminary Check

AIS001HC

POWER SUPPLY AND GROUND CIRCUIT CHECK

1. 

CHECK FUSE

Check that any of the following fuses in BCM and door mirror control unit are blown.

NOTE:
Refer to 

GW-78, "Component Parts and Harness Connector Location"

 .

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

78, "Component Parts and Harness Connector Location"

 .

2. 

POWER SUPPLY CIRCUIT INSPECTION (BCM)

1.

OK or NG?

OK

>> GO TO 3.

NG

>> Repair or replace the harnesses for BCM power supply

circuit.

3. 

GROUND CIRCUIT INSPECTION(BCM)

1.
