INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST BY INTELLIGENT TESTER

  1. Cover the automatic light control sensor with a cloth to prevent it from sensing.

  1. Operate the intelligent tester according to the display and select the "Active Test".

    Combination meter:

    Item
    		Test Details
    		Diagnostic Note
    Indicat. ECD ON
    		Indicat. ECD ON (OFF/ON)
    		-

    OK:
    Cluster glass becomes tinted (minimum value) when the Active Test is ON.



NG
Go to step 5
OK


2.READ VALUE OF INTELLIGENT TESTER

  1. Operate the intelligent tester according to the display and select the "Data List".

    Combination meter:

    Item
    		Measurement Item/ Range (Display)
    		Normal Condition
    		Diagnostic Note
    ECD Sunlight Sensor
    		ECD sunlight sensor input value/
    Min.: 0, Max.: 255
    		Between 50 to 70
    		Light is not shined on automatic light control sensor
    Between "light is not shined on automatic light control sensor" value and 195*1
    		Shine light on automatic light control sensor

    HINT:
    *1: The value changes according to the intensity of the light.
