RELAY ON-VEHICLE INSPECTION

PROCEDURE


  1. INSPECT INTEGRATION RELAY (EFI MAIN)


    1. A002QDB

      Using a screwdriver, detach the 2 claws, and then disconnect the 3 connectors to remove the integration relay from the engine room junction block.

      Tech Tips

      Tape the screwdriver tip before use.

      *a Fuse Side:
      *b EFI MAIN
      *c Connector Side:

      Check the EFI MAIN fuse.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        EFI MAIN fuse Always Below 1 Ω

        If the result is not as specified, replace the EFI MAIN fuse.

    3. Check the EFI MAIN relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1B-4 Battery voltage not applied to terminals 1B-2 and 1B-3 10 kΩ or higher
        1B-1 - 1B-4
        1C-1 - 1B-4 Battery voltage applied to terminals 1B-2 and 1B-3 Below 1 Ω
        1B-1 - 1B-4

        If the result is not as specified, replace the integration relay.

    4. Install the integration relay.

  2. INSPECT INTEGRATION RELAY (IGT/INJ)


    1. Check the IGT/INJ fuse.


      1. A002QE1E02
        *a Fuse Side
        *b Connector Side

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        IGT/INJ fuse Always Below 1 Ω

        If the result is not as specified, replace the IGT/INJ fuse.

    2. Check the IGT/INJ relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1C-1 - 1B-8 Battery voltage not applied to terminals 1B-6 and 1B-7 10 kΩ or higher
        1B-1 - 1B-8
        1C-1 - 1B-8 Battery voltage applied to terminals 1B-6 and 1B-7 Below 1 Ω
        1B-1 - 1B-8

        If the result is not as specified, replace the integration relay.

  3. INSPECT NO. 1 IGNITION RELAY (IG1)

    Note

    The circuit opening relay is built into the main body ECU (instrument panel junction block).


    1. Remove the main body ECU (instrument panel junction block).

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

      *1

      Component without harness connected

      (Main body ECU)
      Standard Resistance
      Tester Connection Condition Specified Condition
      DF-8 - DG-1 Battery voltage not applied to DF-3 (+) and DE-28 (-) 10 kΩ or higher
      DF-8 - DG-1 Battery voltage applied to DF-3 (+) and DE-28 (-) 150 Ω to 200 Ω

      If the result is not as specified, replace the main body ECU (instrument panel junction block).

    3. Install the main body ECU (instrument panel junction block).

  4. INSPECT NO. 2 IGNITION RELAY (IG2)


    1. A002M4HE02
      *a Fuse Side:
      *b Connector Side:

      Check the IG2 fuse.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        IG2 fuse Always Below 1 Ω

        If the result is not as specified, replace the IG2 fuse.

    2. Check 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 - 1A-4 Battery voltage not applied to terminals 1A-2 and 1A-3 10 kΩ or higher
        1A-1 - 1A-4
        1C-1 - 1A-4 Battery voltage applied to terminals 1A-2 and 1A-3 Below 1 Ω
        1A-1 - 1A-4

        If the result is not as specified, replace the integration relay.

  5. INSPECT CIRCUIT OPENING RELAY (C/OPN)
