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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    M2-6 (CLTB) - M2-3 (CLTE)
    		Engine switch on (IG)
    		11 to 14 V

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

    Standard Resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    M2-3 (CLTE) - Body ground
    		Always
    		Below 1 Ω

  1. Reconnect the M2 sensor connector.

  1. Check the waveform of the M2 sensor connector.

    Waveform:
    Tester Connection
    		Tool Setting
    		Switch Condition
    		Specified Condition
    M2-3 (CLTE) - M2-5 (CLTS)
    		5 V/DIV., 5 msec./ DIV.
    		Engine switch on (IG), Headlight dimmer switch on AUTO
    		Correct waveform is as shown
    HINT:
    If the ambient light becomes brighter, width A becomes narrower.
    If the result is not as specified, there may be a malfunction in the sensor.
