RELAY ON-VEHICLE INSPECTION


  1. INSPECT DCU RELAY (DCU)


    1. B007RG1E01

      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.

  2. INSPECT EFI MAIN RELAY (EFI MAIN)


    1. B007QHGE04

      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 NO. 2 RELAY (EFI NO. 2)


    1. B007QHGE04

      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 NO. 2 relay.

  4. INSPECT EDU RELAY (EDU)


    1. B007QHGE04

      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.

  5. INSPECT NOX RELAY (NOX)


    1. B007QHGE04

      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 relay.

  6. INSPECT NO. 2 INTEGRATION RELAY

    Note


    • The IG2 relay is built into the No. 2 integration relay.

    • Before performing the relay inspection for the relay of the No. 2 integration relay, inspect the IG2-MAIN fuse.


    1. Inspect the IG2 relay.
