< COMPONENT DIAGNOSIS >

TURN SIGNAL LAMP CIRCUIT

3.

CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN 

1. Turn the ignition switch OFF.

2. Disconnect BCM connector.

3. Check the continuity between the BCM harness connector and the front combination lamp, the rear com-

bination lamp harness connector or the door mirror connector (if equipped with turn signals in mirrors).

Does continuity exist?

YES

>> GO TO 4

NO

>> Repair the harnesses or connectors.

4.

CHECK TURN SIGNAL LAMP SHORT CIRCUIT

Check continuity between the BCM harness connector and the

ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> GO TO 5

5.

CHECK TURN SIGNAL LAMP GROUND CIRCUIT

Check continuity between the front combination lamp, the rear combination lamp or the door mirror and

ground (if equipped with turn signals in mirrors).

Does continuity exist?

YES

>> Replace the front combination lamp or the rear combination lamp.

NO

>> Repair the harnesses or connectors.

OPTICAL SENSOR

Description

INFOID:0000000004201507

The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to

the BCM.

Component Function Check

INFOID:0000000004201508

1.

CHECK OPTICAL SENSOR SIGNAL BY CONSULT-III

CONSULT-III

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. With the optical sensor illuminating, 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:0000000004201509

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

< COMPONENT DIAGNOSIS >

OPTICAL SENSOR

 With the optical sensor illuminating, check voltage between the opti-

cal sensor harness connector and ground.

*: Illuminate the optical sensor. The value may be less than the standard if brightness
is weak.

Is the voltage reading as specified?

YES

>> GO TO 7

NO

>> Replace the optical sensor.  

4.

CHECK OPTICAL SENSOR POWER SUPPLY FOR OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect the optical sensor connector and BCM connector.

3. Check continuity between the optical sensor harness connector

and the BCM harness connector.

Does continuity exist?

YES

>> GO TO 5

NO

>> Repair the harnesses or connectors.

5.

CHECK OPTICAL SENSOR POWER SUPPLY FOR SHORT CIRCUIT

Check the continuity between the optical sensor harness connector

and the ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> Replace BCM. Refer to 

BCS-96, "Removal and Installa-

tion"

 .

6.

CHECK OPTICAL SENSOR GROUND FOR OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect the optical sensor connector and BCM connector.

3. Check continuity between the optical sensor harness connector

and the BCM harness connector.

Does continuity exist?

YES

>> Replace BCM. Refer to 

BCS-96, "Removal and Installa-

tion"

 .

NO

>> Repair the harnesses or connectors.
