[HALOGEN TYPE]

OPTICAL SENSOR

3.

CHECK OPTICAL SENSOR SIGNAL OUTPUT

 With the auto light system operating, check voltage between the

optical 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. Refer to 

EXL-322, "Removal and Installation"

.

4.

CHECK OPTICAL SENSOR POWER SUPPLY FOR OPEN CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect the optical sensor connector and BCM connector M18.

3. Check continuity between the optical sensor harness connector

(A) and the BCM harness connector (B).

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-79, "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 M18.

3. Check continuity between the optical sensor harness connector

(A) and the BCM harness connector (B).

Does continuity exist?

YES

>> Replace BCM. Refer to 

BCS-79, "Removal and Installa-

tion"

.

NO

>> Repair the harnesses or connectors.
