        Tester Connection Specified Condition
        1I-5 ←→ negative battery terminal (-) battery voltage
        1I-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 HAZ-HORN fuse 2 (+) and battery negative (-) lead to terminal 1I-7.Using a voltmeter, measure the voltage according to the value 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
        1I-8 (+) ←→ negative battery terminal (-)

        battery voltage

        (When battery voltage is applied to terminals HAZ-HORN fuse 2 (+) and 1I-7)

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

    4. A01BDBSE06

      Measure the resistance of the EFI MAIN relay.


      1. Using an ohmmeter, measure the resistance according to the values in the table below.
