2. Turn each interior lamp to the ON position.

-

Interior room lamp

-

Map lamp (if equipped)

-

Cargo 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.

Is the inspection result normal?

YES

>> Battery saver output/power supply circuit is normal.

NO

>> Refer to 

INL-41, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009695420

Regarding Wiring Diagram information, refer to 

INL-21, "Wiring Diagram"

.

1.

CHECK BATTERY SAVER OUTPUT/POWER SUPPLY OUTPUT

CONSULT

1. Turn ignition switch ON.

2. Select BATTERY SAVER of BCM (BATTERY SAVER) active test item.

3. While operating the test item, check voltage between BCM connector and ground.

With Intelligent Key

Without Intelligent Key

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace BCM after making sure battery saver output/power supply circuit is not shorted to volt-

age. Refer to 

BCS-70, "Removal and Installation"

 (with Intelligent Key) or 

BCS-127, "Removal

and Installation"

 (without Intelligent Key).

INTERIOR ROOM LAMP CONTROL CIRCUIT

Description

INFOID:0000000009695421

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:0000000009695422

CAUTION:

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

• Interior room lamp power supply

• Map lamp bulb

• Room lamp bulb

1.

CHECK INTERIOR ROOM LAMP CONTROL FUNCTION

CONSULT

1. Switch the map lamp switch or interior room lamp switch to DOOR.

2. Turn ignition switch ON.

3. Select INT LAMP of BCM (INT LAMP) ACTIVE TEST item.

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

Does the interior room lamp turns ON/OFF (gradual brightening/dimming)?

YES

>> Interior room lamp control circuit is normal.

NO

>> Refer to 

INL-43, "Diagnosis Procedure"

.
