      Front view of wire harness connector

      (to Automatic Light Control Sensor)

      Disconnect the L1 automatic light control sensor connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      L1-1 (CLTB) - L1-2 (CLTE) Power switch off Below 1 V
      Power switch on (IG) 11 to 14 V
      Standard Resistance
      Tester Connection Condition Specified Condition
      L1-2 (CLTE) - Body ground Always Below 1 Ω

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

      Component with harness connected

      (Automatic Light Control Sensor)

      Reconnect the L1 automatic light control sensor connector.

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

    5. A00235GN01

      Check the waveform.

      OK
      Tester Connection Tool Setting Condition Specified Condition
      L1-4 (CLTS) - L1-2 (CLTE) 2 V/DIV., 10 ms./DIV. Power switch on (IG), light control switch in AUTO position Correct waveform is as shown

      Tech Tips

      The communication waveform changes according to the surrounding brightness.

      If the result is not as specified, the automatic light control sensor may be malfunctioning.
