EXL-52

< COMPONENT DIAGNOSIS >

OPTICAL SENSOR

3.

CHECK OPTICAL SENSOR SIGNAL OUTPUT

 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 measurement value normal?

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-87, "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.
