    Component without harness connected

    (No. 1 Integration Relay)

    		 - -

    Note


    • The EDU relay, IG2 relay, EFI MAIN1 relay and EFI MAIN2 relay are built into the No. 1 integration relay.

    • Before performing the relay inspections for the relays of the No. 1 integration relay, inspect the EDU, IG2, EFI-MAIN NO. 1 and EFI-MAIN NO. 2 fuses.


    1. Inspect the EDU relay.


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

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

        If the result is not as specified, replace the No. 1 integration relay.

    2. Inspect the IG2 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1J-7 Battery voltage not applied to terminals 1J-6 and 1J-3 10 kΩ or higher
        Battery voltage applied to terminals 1J-6 and 1J-3 Below 1 Ω

        If the result is not as specified, replace the No. 1 integration relay.

    3. Inspect the EFI MAIN1 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1J-10 Battery voltage not applied to terminals 1K-7 and 1J-3 10 kΩ or higher
        Battery voltage applied to terminals 1K-7 and 1J-3 Below 1 Ω

        If the result is not as specified, replace the No. 1 integration relay.

    4. Inspect the EFI MAIN2 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1J-12 Battery voltage not applied to terminals 1J-10 and 1J-3 10 kΩ or higher
        Battery voltage applied to terminals 1J-10 and 1J-3 Below 1 Ω

        If the result is not as specified, replace the No. 1 integration relay.

  2. INSPECT DCU RELAY (DCU)


    1. A01XFWZE03

      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 DCU relay.

  3. INSPECT NOx PM RELAY (NOx PM)


    1. B001CVZE10

      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 NOx PM relay.
