Diagnosis Procedure

INFOID:0000000004219080

1.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Disconnect the battery cable from the negative terminal.

3. Check the terminals and connectors of the BCM for damage, bend and loose connection (unit side and

connector side).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1. Disconnect the connector of BCM.

2. Check the resistance between the BCM harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the BCM branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the BCM. Refer to 

BCS-42, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the BCM. Refer to 

BCS-87, "Removal and Installation"

.

YES (Past error)>>Error was detected in the BCM branch line.

NO

>> Repair the power supply and the ground circuit.
