PROCEDURE


  1. INSPECT INJ RELAY (INJ)


    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 INJ relay.

  2. INSPECT A/F HTR RELAY (A/F HTR)

    B0026S9E05

    1. 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 A/F HTR relay.

  3. INSPECT INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY

    B00258ZC01
    *a

    Components without harness connected

    (Instrument Panel Junction Block Assembly)

    		 - -

    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.

      Note

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


      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-9 and 2J-5 10 kΩ or higher
        Battery voltage applied to terminals 2P-9 and 2J-5 Below 1 Ω
        2B-1 - 2K-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
        2B-1 - 2K-4 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
        2B-1 - 2N-1 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.

    4. Inspect the C/OPN NO. 1 relay.

      Note

      Before performing the relay inspections for the relays of instrument panel junction block assembly, inspect the EFI-MAIN NO. 1 and IG2 NO. 1 fuses and 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 - 2K-5 Battery voltage applied to terminals 2P-9 and 2J-5 and battery voltage not applied to terminals 2G-1 and 2P-8 10 kΩ or higher
        Battery voltage applied to terminals 2P-9 and 2J-5, and 2G-1 and 2P-8 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.
