INTERIOR ROOM LAMP CONTROL CIRCUIT
INTERIOR ROOM LAMP CONTROL CIRCUIT
DescriptionINFOID:0000000003774558
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 CheckINFOID:0000000003774559
NOTE:
Replace the personal lamp assembly if the map lamp is turned ON but the personal lamp LH and RH are not
turn ON.
CAUTION:
Before performing the diagnosis, check that the following is normal.
• Interior room lamp power supply
 Map lamp bulb
 Personal lamp bulb
1.CHECK INTERIOR ROOM LAMP CONTROL FUNCTION
CONSULT-III ACTIVE TEST
1. Switch the map lamp switch to DOOR.
2. Turn ignition switch ON.
3. Select “INT LAMP” of BCM (INT LAMP) active test item.
4. With operating the test items, check that each interior room lamp turns ON/OFF (gradual brightening/dim-
ming).
Does the interior room lamp turns ON/OFF (gradual brightening/dimming)?
YES >> Interior room lamp control circuit is normal.
NO >> Refer to INL-22, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003774560
1.CHECK INTERIOR ROOM LAMP CONTROL OUTPUT
CONSULT-III ACTIVE TEST
1. Turn ignition switch OFF.
2. Remove all the bulbs of map lamp and personal lamp.
3. Select “INT LAMP” of BCM (INT LAMP) active test item.
4. With operating the test item, check continuity between BCM harness connector and ground.
Is the measurement value normal?
YES >> GO TO 2.
Fixed ON>>GO TO 3.
Fixed OFF>>Replace BCM.
2.CHECK INTERIOR ROOM LAMP CONTROL OPEN CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector and map lamp connector.
3. Check continuity between BCM harness connector and map lamp harness connector. On : Interior room lamp gradual brightening
Off : Interior room lamp gradual dimming
