Diagnosis Procedure

INFOID:0000000009160345

1.

CHECK LICENSE PLATE LAMP BULB

Check the applicable lamp bulb.
Is the bulb normal?

YES

>> GO TO 2.

NO

>> Replace the bulb.

2.

CHECK LICENSE PLATE LAMP OPEN CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect IPDM E/R connector and the license plate lamp connector.

OPTICAL SENSOR

OPTICAL SENSOR

Description

INFOID:0000000009160346

Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.

Diagnosis Procedure

INFOID:0000000009160348

1.

CHECK OPTICAL SENSOR POWER SUPPLY INPUT

1.

Turn the ignition switch ON.

2.

Turn the lighting switch AUTO.

3.

Check the voltage between the optical sensor harness connector and the ground.

Is the measurement value normal?

YES

>> GO TO 2.

NO

>> GO TO 4.

2.

CHECK OPTICAL SENSOR GROUND INPUT

Check the voltage between the optical sensor harness connector and the ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> GO TO 6.

3.

CHECK OPTICAL SENSOR SIGNAL OUTPUT

 With illuminating the optical sensor, check the voltage between the optical sensor harness connector and the
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 OPEN CIRCUIT

1.

Turn the ignition switch OFF.
