NOTICE:
  1. The IG2 relay, EFI relay and EFI MAIN relay are built into the No. 1 integration relay.
  2. Before performing the relay inspections for the relays of the No. 1 integration relay, inspect the IG2, EFI-MAIN NO. 1 and EFI-MAIN NO. 2 fuses.
  1. 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 - 1A-4
      Battery voltage not applied to terminals 1A-1 and 1A-3
      10 kΩ or higher
      Battery voltage applied to terminals 1A-1 and 1A-3
      Below 1 Ω
      If the result is not as specified, replace the No. 1 integration relay.
  1. Inspect the EFI 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
      Battery voltage applied to terminals 1B-2 and 1B-3
      Below 1 Ω
      If the result is not as specified, replace the No. 1 integration relay.
  1. Inspect 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-8
      Battery voltage not applied to terminals 1B-5 and 1B-7
      10 kΩ or higher
      Battery voltage applied to terminals 1B-5 and 1B-7
      Below 1 Ω
      If the result is not as specified, replace the No. 1 integration relay.


2. INSPECT EDU RELAY (EDU)

  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 EDU relay.


3. INSPECT FUEL PUMP RELAY (FUEL PMP) (for Double Tank Type)
