Description
The optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to the BCM.
Component Function Check
1.CHECK OPTICAL SENSOR SIGNAL BY CONSULT
CONSULT
*: Illuminates the optical sensor. The value may be less than the standard value if brightness is weak.
Diagnosis Procedure
1.CHECK OPTICAL SENSOR POWER SUPPLY INPUT
2.CHECK OPTICAL SENSOR GROUND INPUT
Check the voltage between the optical sensor harness connector and ground
3.CHECK OPTICAL SENSOR SIGNAL OUTPUT
With the auto light system operating, check voltage between the optical sensor harness connector and ground.
4.CHECK OPTICAL SENSOR POWER SUPPLY FOR OPEN CIRCUIT
5.CHECK OPTICAL SENSOR POWER SUPPLY FOR SHORT CIRCUIT
Check the continuity between the optical sensor harness connector and the ground.
6.CHECK OPTICAL SENSOR GROUND FOR OPEN CIRCUIT
7.CHECK OPTICAL SENSOR SIGNAL FOR OPEN CIRCUIT
8.CHECK OPTICAL SENSOR SIGNAL FOR SHORT CIRCUIT
heck the continuity between the optical sensor harness connector and ground.
