INTERIOR ROOM LAMP CONTROL CIRCUIT
INTERIOR ROOM LAMP CONTROL CIRCUIT
DescriptionINFOID:0000000006216068
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:0000000006216069
CAUTION:
Before performing the diagnosis, check that the following are normal.
Interior room lamp power supply
Map lamp bulb
Personal lamp bulb
Foot lamp bulb
1.CHECK INTERIOR ROOM LAMP CONTROL FUNCTION
CONSULT-III ACTIVE TEST
1. Switch the map lamp switch and personal 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, c heck 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-58, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000006216070
1.CHECK INTERIOR ROOM LAMP CONTROL OUTPUT
CONSULT-III ACTIVE TEST
1. Switch the map lamp switch and personal lamp switch to DOOR.
2. Turn ignition switch OFF.
3. Remove all the bulbs of map lamp, foot lamp and personal lamp.
4. Turn ignition switch ON.
5. Select “INT LAMP” of BCM (INT LAMP) active test item.
6. With operating the test item, check c ontinuity between BCM harness connector and ground.
Is the inspection result normal?
YES >> GO TO 2.
Fixed ON>>GO TO 3.
Fixed OFF>>Replace BCM. Refer to BCS-81, "
Removal and Installation".
2.CHECK INTERIOR ROOM LAMP CONTROL OPEN CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector, map lamp connector, personal lamp connector and foot lamp connector.
3. Check continuity between BCM harness connector and foot lamp harness connector.
On : Interior room lamp gradual brightening
Off : Interior room lamp gradual dimming
