LIGHTING: AUTOMATIC LIGHT CONTROL SENSOR: ON-VEHICLE INSPECTION

1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR





(a) Connect the voltmeter's positive (+) lead to terminal M2-6 and the negative (-) lead to terminal M2-3.

(b) Measure the voltage of the connector.

Standard voltage:





(c) Measure the resistance of the connector.

Standard resistance:





(d) Check the waveform of the M2 sensor connector.





Wave form:





HINT
If the ambient light becomes brighter, width A becomes narrower.

If the result is not as specified, replace the automatic light control sensor.
