PROCEDURE


  1. INSPECT EDU RELAY (EDU)


    1. B0026S9E05

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Battery voltage not applied to terminals 1 and 2 10 kΩ or higher
      Battery voltage applied to terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the EDU relay.

  2. INSPECT IG2 RELAY (IG2)


    1. B0026S9E05

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 - 5 Battery voltage not applied to terminals 1 and 2 10 kΩ or higher
      Battery voltage applied to terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the IG2 relay.

  3. INSPECT INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY

    B00278FC01
    *a

    Component without harness connected

    (Instrument Panel Junction Block Assembly)

    		 - -

    Note

    Before performing the relay inspections for the relays of the instrument panel junction block assembly, inspect the EFI-MAIN NO. 1, EFI-MAIN NO. 2 and EFI NO. 1 fuses.


    1. Remove the instrument panel junction block assembly.


    2. Remove the body ECU from the instrument panel junction block assembly.


    3. Inspect the EFI-MAIN NO. 1 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2B-1 - 2G-5 Battery voltage not applied to terminals 2P-8 and 2K-3 10 kΩ or higher
        Battery voltage applied to terminals 2P-8 and 2K-3 Below 1 Ω

        If the result is not as specified, replace the instrument panel junction block assembly.

    4. Inspect the EFI-MAIN NO. 2 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2B-1 - 2G-3 Battery voltage not applied to terminals 2P-9 and 2J-5 10 kΩ or higher
        Battery voltage applied to terminals 2P-9 and 2J-5 Below 1 Ω

        If the result is not as specified, replace the instrument panel junction block assembly.

    5. Install the body ECU to the instrument panel junction block assembly.


    6. Install the instrument panel junction block assembly.
