RELAY ON-VEHICLE INSPECTION


  1. INSPECT DIESEL ECU RELAY (EDU)


    1. A01CHI1E90

      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 diesel ECU relay.

  2. INSPECT ACTUATOR POWER RELAY (ENG ACT)


    1. A01CHI1E90

      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 actuator power relay.

    Note

    Before performing the relay inspections for the relays of the instrument panel junction block assembly, inspect the ECU IG NO. 1 and IG1 fuses.


    1. Inspect the ENG ECU relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2B-3 - 2B-40 Battery voltage is not applied to terminals 2B-15 and 2B-19 10 kΩ or higher
        Battery voltage is applied to terminals 2B-15 and 2B-19 Below 1 Ω

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

    2. Inspect the IG1-1 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2A-4 - 2C-19 Battery voltage is not applied to terminals 2B-29 and 2C-9 10 kΩ or higher
        Battery voltage is applied to terminals 2B-29 and 2C-9 Below 1 Ω

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

    3. Inspect the IG1-2 relay.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        2A-3 - 2B-8 Battery voltage is not applied to terminals 2B-29 and 2C-9 10 kΩ or higher
        Battery voltage is applied to terminals 2B-29 and 2C-9 Below 1 Ω

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