BCM : Diagnosis Procedure

INFOID:0000000004469737

1.

 CHECK FUSE AND FUSIBLE LINK

Check if the following BCM fuse or fusible link are blown.

Is the fuse or fusible link blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2

2.

 CHECK POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect BCM.

3. Check voltage between BCM harness connector and ground.

Is the measurement normal?

YES

>> GO TO 3

NO

>> Repair or replace harness.

3.

 CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> Inspection End.

NO

>> Repair or replace harness.

Provides the battery saver output/power supply. Also cuts the power supply when the interior room lamp bat-

tery saver is activating.

Component Function Check

INFOID:0000000004216471

1.

CHECK BATTERY SAVER OUTPUT/POWER SUPPLY FUNCTION

CONSULT-III

1. Turn ignition switch ON.

2. Turn each interior room lamp ON.

-

Front room/map lamps

-

Personal lamps rear

-

Step lamps

-

Vanity mirror lamps

-

Trunk room lamp

3. Select "BATTERY SAVER" of BCM (BATTERY SAVER) active test item.

4.  While operating the test item, check that each interior room lamp turns ON/OFF.

INTERIOR ROOM LAMP CONTROL CIRCUIT

INTERIOR ROOM LAMP CONTROL CIRCUIT

Description

INFOID:0000000004216473

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:0000000004216474

CAUTION:

 Before performing the diagnosis, check that the following is normal.

• Battery saver output/power supply

• Front room/map lamp assembly bulbs

• Personal lamp rear bulbs
