    *1 Main Body ECU - -
    *a Component without harness connected
    (Junction Block)    		 *b Component without main body ECU connected
    (Junction Block)
    NOTE:

    Before performing the relay inspections for the relays of the junction block, inspect the ECU-IG NO. 2, ECU-IG NO. 4 and ECU-IG NO. 5 fuses.

    1. Inspect the IG1 NO. 1 relay.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        4F-1 - 4C-21 Battery voltage not applied to terminals 4B-46 and -4D-28 10 kΩ or higher
        Battery voltage applied to terminals 4B-46 and 4D-28 Below 1 Ω

        If the result is not as specified, replace the junction block.

    2. Inspect the IG1 NO. 2 relay.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        4F-1 - 4C-41 Battery voltage not applied to terminals 4B-46 and -4D-28 10 kΩ or higher
        Battery voltage applied to terminals 4B-46 and 4D-28 Below 1 Ω

        If the result is not as specified, replace the junction block.

    3. Inspect the IG1 NO. 3 relay.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        4F-1 - 4D-34 Battery voltage not applied to terminals 4B-46 and -4D-28 10 kΩ or higher
        Battery voltage applied to terminals 4B-46 and 4D-28 Below 1 Ω

        If the result is not as specified, replace the junction block.

  2. INSPECT EFI MAIN RELAY (EFI MAIN)

    1. 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 EFI main relay.

  3. INSPECT EFI MAIN NO. 2 RELAY (EFI MAIN NO. 2) 
    GTY373106Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    1. 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 EFI main No. 2 relay.

  4. INSPECT IGNITION NO. 2 MAIN RELAY (IG2-MAIN) 
    GTY373106Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
    1. 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 ignition No. 2 main relay.
