• Vehicle Condition (BCM detected condition)

IGN Counter

IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
• The number is 0 when a malfunction is detected now.
• The number increases like 1

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connectors.

3.

Check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> INSPECTION END

NO

>> Repair harness or connector.
