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

the front combination lamp connector (B).

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 

EXL-53, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000010050235

Regarding Wiring Diagram information, refer to 

EXL-106, "Wiring Diagram"

.

1.

CHECK OPTICAL SENSOR POWER SUPPLY INPUT

1. Turn the ignition switch ON.

2. Turn the lighting switch to AUTO.

3. Check the voltage between the optical sensor harness connec-

tor and ground.

Is the voltage reading as specified?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK OPTICAL SENSOR GROUND INPUT

Check the voltage between the optical sensor harness connector

and ground.

Is the voltage reading as specified?

YES

>> GO TO 3.

NO

>> GO TO 6.
