PROCEDURE


  1. INSPECT NO. 1 INTEGRATION RELAY

    B001CKCC01
    *a

    Component without harness connected

    (No. 1 Integration Relay)

    		 - -

    Note


    • The EDU relay, IG2 relay, EFI MAIN NO. 1 relay, EFI MAIN NO. 2 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 EDU, IG2, EFI MAIN NO. 1, EFI MAIN NO. 2 and FUEL PMP 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
        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.

    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-10 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 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
        1S-1 - 1W-3 Battery voltage not applied to terminals 1W-1 and 1W-4 10 kΩ or higher
        Battery voltage applied to terminals 1W-1 and 1W-4 Below 1 Ω

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

    5. 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.
