  1. Disconnect the E11 automatic light control sensor connector.

  1. Measure the voltage and resistance according to the value(s) in the table below.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    E11-6 (CLTB) - E11-3 (CLTE)
    		Ignition switch OFF
    		Below 1 V
    Ignition switch ON
    		10 to 14 V
    Standard resistance:
    Tester Connection
    		Specified Condition
    E11-3 (CLTE) - Body ground
    		Below 1 Ω
    If the result is not as specified, there may be a malfunction on the wire harness side.

  1. Reconnect the automatic light control sensor connector.

  1. Connect an oscilloscope to the automatic light control sensor connector.

  1. Check the waveform.

    OK:
    Tester Connection
    		Tool Setting
    		Condition
    		Specified Condition
    E11-3 (CLTE) - E11-5 (CLTS)
    		5 V/DIV., 5 ms./DIV
    		Ignition switch ON, light control switch in AUTO
    		Correct waveform is as shown
    HINT:
    If the ambient light becomes brighter, width A becomes narrower.
    If the result is not as specified, replace the automatic light control sensor.
