< COMPONENT DIAGNOSIS >

TURN SIGNAL LAMP CIRCUIT

Is voltage reading as specified?

YES

>> GO TO 3

NO

>> Replace BCM. Refer to 

BCS-59, "Removal and Installation"

.

3.

CHECK TURN SIGNAL LAMP CIRCUIT FOR OPEN 

1. Turn the ignition switch OFF.

2. Disconnect BCM connector M20.

3. Check continuity between the BCM harness connector M20 (A)

and the front combination lamps harness connector (B).

4. Check continuity between the BCM harness connector M20 (A)

and the rear combination lamp harness connectors (B). 

Are continuity results as specified?

YES

>> GO TO 4

NO

>> Repair the harnesses or connectors.

4.

CHECK TURN SIGNAL LAMP SHORT CIRCUIT

Check continuity between the BCM harness connector M20 and

ground.

Does continuity exist?

YES

>> Repair the harnesses or connectors.

NO

>> GO TO 5

OPTICAL SENSOR

OPTICAL SENSOR

Description

INFOID:0000000005259755

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

the BCM.

Component Function Check

INFOID:0000000005259756

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-52, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005259757

Regarding Wiring Diagram information, refer to 

EXL-66, "Wiring Diagram"

.

1.

CHECK OPTICAL SENSOR GROUND CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect BCM connector M18 and optical sensor connector

M145.

3. Check continuity between BCM harness connector M18 (A) ter-

minal 18 and optical sensor harness connector M145 (B) termi-

nal 3.

4. Check continuity between BCM harness connector M18 (A) ter-

minal 18 and ground. 

Are continuity results as specified?

YES

>> GO TO 2

NO

>> Repair harness or connector.
