      Front view of wire harness connector

      (to Automatic Light Control Sensor (Solar Sensor))

      Disconnect the J6 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
      J6-1 (CLTB) - J6-2 (CLTE) Engine switch off, dimmer switch off, 2 minutes after all doors closed Below 1 V
      Engine switch on (IG) 11 to 14 V
      Standard Resistance
      Tester Connection Condition Specified Condition
      J6-2 (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 (Solar Sensor))

      Reconnect the J6 automatic light control sensor connector.

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

    5. A01HIEKN01

      Check the waveform.

      OK
      Tester Connection Tool Setting Condition Specified Condition
      J6-4 (CLTS) - J6-2 (CLTE) 2 V/DIV., 10 ms./DIV. Engine switch on (IG) 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.
