TURN SIGNAL LAMP CIRCUIT
5. With turn signal switch operating, check the voltage between the rear combination lamp harness connec-
tor and ground.
6. With turn signal switch operating, check the voltage between the door mirror (if equipped with turn signals
in the mirrors) harness connector and ground.
Is the measurement value normal?
YES
>> GO TO 5.
NO
>> GO TO 3.
3.
CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN
1. Turn ignition switch OFF.
2. Disconnect BCM connector M17.
3. Check continuity between the BCM harness connector (A) and

OPTICAL SENSOR
Description
INFOID:0000000010050233
The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to
the BCM.
Component Function Check
INFOID:0000000010050234
1.
CHECK OPTICAL SENSOR SIGNAL BY CONSULT
CONSULT
1. Turn the ignition switch ON.
2. Select “OPTICAL SENSOR” of BCM (HEAD LAMP) DATA MONITOR item.
3. Turn the lighting switch to AUTO.
4. While the auto light system is operating, check the monitor status.
*: Illuminates the optical sensor. The value may be less than the standard value if brightness is weak.
Is the item status normal?
YES
>> Optical sensor is normal.
NO
>> Refer to
.
Diagnosis Procedure
INFOID:0000000010050235
Regarding Wiring Diagram information, refer to
.
1.
