      Disconnect the E20 connector.

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

      Standard voltage
      Tester Connection Condition Specified Condition
      E20-1 (B) - Body ground Always 11 to 14 V
      E20-3 (ILL+) - Body ground Ignition switch on (IG), light control switch OFF Below 1 V
      Ignition switch on (IG), light control switch TAIL/HEAD 11 to 14 V
      E20-4 (ACC) - Body ground Ignition switch off Below 1 V
      Ignition switch on (ACC) 11 to 14 V

      1. A017EKZE01

        Waveform (Reference): Using oscilloscope:

        Item Condition
        Tool setting 2 V/DIV., 1 ms./DIV.
        Vehicle condition Ignition switch on (IG), light control switch TAIL/HEAD

        Tech Tips


        • Duty ratio changes as the illumination becomes darker (the period "A" shown in the illustration becomes longer).

        • If the value is not as specified, repair or replace the wire harness or connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      E20-2 (E) - Body ground Always Below 1 Ω

      Tech Tips

      If the value is not as specified, repair or replace the wire harness or connector.

  2. INSPECT CLOCK ASSEMBLY (w/ Multi-information Display)


    1. A017C1XE19

      Disconnect the E9 connector.

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

      Standard voltage
      Tester Connection Condition Specified Condition
      E9-1 (IG) - Body ground Ignition switch off Below 1 V
      Ignition switch on (IG) 11 to 14 V
      E9-6 (+B) - Body ground Always 11 to 14 V

      Tech Tips

      If the value is not as specified, repair or replace the wire harness or connector.

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

      Standard resistance
      Tester Connection Condition Specified Condition
      E9-5 (GND) - Body ground Always Below 1 Ω

      Tech Tips

      If the value is not as specified, repair or replace the wire harness or connector.
