EXL-52 < DTC/CIRCUIT DIAGNOSIS > [XENON TYPE] OPTICAL SENSOR OPTICAL SENSOR Description INFOID:0000000009722918 Optical sensor converts the outside brightness (lux) to voltage and transmits the optical sensor signal to BCM. Component Function Check INFOID:0000000009722919 1. CHECK OPTICAL SENSOR SIGNAL BY CONSULT CONSULT DATA MONITOR 1. Turn the ignition switch ON. 2. Select "OPTICAL SENSOR" of BCM (HEADLAMP) data monitor item. 3. Turn the lighting switch AUTO. 4. With the optical sensor illuminating, check the monitor status. *: Illuminates the optical sensor. The value may be less than the standard value if brightness is weak. Is the item status normal? YES >> Optical sensor is normal. NO >> Refer to . Diagnosis Procedure INFOID:0000000009722920 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. Monitor item Condition Voltage (Approx.)
