RELAY(w/ Urea SCR System) ON-VEHICLE INSPECTION

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 and EFI MAIN NO. 2 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 and EFI MAIN NO. 2 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.

  2. INSPECT DCU RELAY (DCU)


    1. B001GRNN10

      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 DCU relay.

  3. INSPECT NOx PM RELAY (NOx PM)


    1. B001CVZN33

      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 NOx PM relay.
