PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - BATTERY AND BODY GROUND)


    1. A00YU42C02
      *a

      Front vie of wire harness connector

      (to Instrument Panel Junction Block Assembly)

      Disconnect the instrument panel junction block assembly connectors.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3D-9 - Body ground Always Below 1 Ω

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

      Standard Voltage
      Tester Connection Condition Specified Condition
      3A-1 - Body ground Always 11 to 14 V
      3C-44 - Body ground Ignition switch ON 11 to 14 V
      Ignition switch off Below 1 V
      Result
      Proceed to
