BCM : Diagnosis Procedure

INFOID:0000000001099291

1.

CHECK FUSES AND FUSIBLE LINK

Check that the following fuses and fusible link are not fusing.

Is the fuse fusing?

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.

Terminal No.

INTERIOR ROOM LAMP CONTROL CIRCUIT

INTERIOR ROOM LAMP CONTROL CIRCUIT

Description

INFOID:0000000001033378

Controls each interior room lamp (ground side) by PWM signal.
NOTE:
PWM signal control period is approximately 250 Hz (in the gradual brightening/dimming).

Component Function Check

INFOID:0000000001033379

CAUTION:

 Before the diagnosis, check that the following items are normal.
• Interior room lamp power supply
• Map lamp bulb
• Room lamp bulb
• Personal lamp bulb
• Luggage room lamp bulb

1.

CHECK INTERIOR ROOM LAMP CONTROL FUNCTION

CONSULT-III ACTIVE TEST

1.
