    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.

    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.
