PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (POWER SOURCE)


    1. Disconnect the stereo component amplifier assembly connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      H59-2 (GND) - Body ground Always Below 1 Ω
      H59-6 (GND2) - Body ground Always Below 1 Ω
      H55-10 (LRHD) - Body ground*1 Always Below 1 Ω

      • *1: for RHD

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      H59-1 (+B) - H59-2 (GND) Power switch off 11 to 14 V
      H59-3 (+B2) - H59-2 (GND) Power switch off 11 to 14 V
      H55-12 (ACC) - H59-2 (GND) Power switch on (ACC) 11 to 14 V
