On-Vehicle Inspection

  1. INSPECT AUTOMATIC LIGHT CONTROL SENSOR (for Manual Air Conditioning System) 
    1. Disconnect the E11 automatic light control sensor connector.
    2. Measure the voltage and resistance according to the value(s) in the table below.

      Standard voltage 

      VOLTAGE SPECIFICATION

      Tester Connection Condition Specified Condition
      E11-3 (CLTB) - E11-6 (CLTE) Ignition switch off Below 1 V
      Ignition switch on (IG) 10 to 14 V

      Standard resistance 

      RESISTANCE REFERENCE

      Tester Connection Specified Condition
      E11-6 (CLTE) - Body ground Below 1 Ω

      If the result is not as specified, there may be a malfunction on the wire harness side.

    3. Reconnect the automatic light control sensor connector.
    4. Connect an oscilloscope to the automatic light control sensor connector.

    5. Check the waveform.

      OK 

      WAVEFORM REFERENCE

      Tester Connection Tool Setting Condition Specified Condition
      E11-6 (CLTE) - E11-4 (CLTS) 5 V/DIV., 5 ms./DIV Ignition switch on (IG), 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.

      WAVEFORM REFERENCE

      Tester Connection Tool Setting Condition Specified Condition
      E11-3 (CLTE) - E11-5 (CLTS) 5 V/DIV., 5 ms./DIV Ignition switch on (IG), 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.
