LIGHT & RAIN SENSOR
DescriptionINFOID:0000000001523274
The light and rain sensor converts outside light (lux) to voltage and transmits the light and rain sensor signal to
the BCM.
Component Function CheckINFOID:0000000001523275
1.CHECK LIGHT AND RAIN SENSOR SIGNAL BY CONSULT-III
CONSULT-III
1. Turn the ignition switch ON.
2. Select "LIT-SEN FAIL" of BCM (HEAD LAMP) DATA MONITOR item.
3. Check the monitor status.
Is the item status OK?
YES >> Light and rain sensor is OK.
NO >> Refer to EXL-55, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001523276
1.CHECK LIGHT AND RAIN SENSOR POWER SUPPLY
1. Turn the ignition switch ON.
2. Check the voltage between the light and rain sensor harness connector and ground.
Is the voltage as specified?
YES >> GO TO 2
NO >> GO TO 4
2.CHECK LIGHT AND RAIN SENSOR GROUND CIRCUIT
Check the voltage between the light and rain sensor harness connector R11 terminal 3 and ground.
Is the voltage as specified?
YES >> GO TO 3
NO >> Repair the harness or connector.
3.CHECK LIGHT AND RAIN SENSOR SIGNAL FOR OPEN OR SHORT CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect the light and rain sensor connector R11 and BCM connector M19.
3. Check continuity between the light and rain sensor harness connector R11 (A) terminal 2 and the BCM
harness connector M19 (B) terminal 63.
