INTEGRATION RELAY INSPECTION


  1. INSPECT INTEGRATION NO.1 RELAY


    1. A01BDBSE06

      Measure the resistance of the EFI MAIN relay.


      1. Using an ohmmeter, measure the resistance.

        Standard resistance
        Tester Connection Specified Condition
        1J-2 - 1J-3 Approx. 310 Ω
        1J-1 - 1J-4 10 kΩ or higher

      2. Connect the battery positive (+) lead to terminal 1J-2 and negative (-) lead to terminal 1J-3. Using an ohmmeter, measure the resistance.

        Standard resistance
        Tester Connection Specified Condition
        1J-1 - 1J-4

        Below 1 Ω

        (When battery voltage is applied to terminals 1J-2 and 1J-3)

        If the resistance is not as specified, replace the integration relay.

    2. A01BDBSE06

      Measure the resistance of the EDU relay.


      1. Using an ohmmeter, measure the resistance.

        Standard resistance
        Tester Connection Specified Condition
        1J-4 - 1J-7 Approx. 310 Ω

        If the resistance is not as specified, replace the integration relay.

    3. A01BDBSE06

      Measure the voltage of the EDU relay.


      1. Connect the battery positive (+) lead to terminal 1J-4.Using a voltmeter, measure the voltage according to the values in the table below.

        Note

        While using the battery for inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

        Standard voltage
        Tester Connection Specified Condition
        1J-5 (+) - Negative battery terminal (-) 11 to 14 V
        1J-8 (+) - Negative battery terminal (-) 0 V

        If the voltage is not as specified, replace the integration relay.

      2. Connect the battery positive (+) lead to terminal 1J-4 and battery negative (-) lead to terminal 1J-7. Using a voltmeter, measure the voltage.

        Note

        While using the battery for inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

        Standard voltage
        Tester Connection Specified Condition
        1J-8 (+) - Negative battery terminal (-)

        11 to 14 V

        (When battery voltage is applied to terminals 1J-4 and 1J-7)

        If the voltage is not as specified, replace the integration relay.
