    *a

    Component without harness connected

    (No. 1 Integration Relay)

    		 - -

    Note


    • The EDU relay, IG2 relay, EFI MAIN NO. 1 relay and FUEL PMP 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 IG2, EFI MAIN NO. 1 and FUEL PMP fuses.


    1. Inspect the FUEL PMP relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1S-1 - 1V-6 Battery voltage not applied to terminals 1S-1 and 1V-7 10 kΩ or higher
        Battery voltage applied to terminals 1S-1 and 1V-7 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
        1S-1 - 1V-1 Battery voltage not applied to terminals 1V-2 and 1W-4 10 kΩ or higher
        Battery voltage applied to terminals 1V-2 and 1W-4 Below 1 Ω

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

    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
        1S-1 - 1W-11 Battery voltage not applied to terminals 1W-8 and 1W-4 10 kΩ or higher
        Battery voltage applied to terminals 1W-8 and 1W-4 Below 1 Ω

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

    4. Inspect the EDU relay.


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

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

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

  4. INSPECT MAIN BODY ECU (DRIVER SIDE JUNCTION BLOCK)

    B001EBIC01
    *a

    Component without harness connected

    (Main Body ECU)

    		 - -

    Note


    • The ACC relay are built into the main body ECU (driver side junction block).

    • Before performing the relay inspections for the relay of the main body ECU (driver side junction block), inspect the ACC fuse.


    1. Inspect the ACC relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2K-1 - 2O-50 Battery voltage not applied to terminals 2N-1 and 2O-23 10 kΩ or higher
        Battery voltage applied to terminals 2N-1 and 2O-23 Below 1 Ω

        If the result is not as specified, replace the main body ECU.
