    INSPECT ENGINE ROOM JUNCTION BLOCK ASSEMBLY


    1. Inspect the EFI No. 1 fuse.


      1. Remove the EFI No. 1 fuse.

      2. Using an ohmmeter, measure the resistance of the fuse.

        Standard resistance
        Tester Connection Condition Specified Condition
        EFI No. 1 fuse Always Below 1 Ω

    2. Inspect the A/F fuse.


      1. Remove the A/F fuse.

      2. Using an ohmmeter, measure the resistance of the fuse.

        Standard resistance
        Tester Connection Condition Specified Condition
        A/F fuse Always Below 1 Ω

    3. Inspect EFI relay.


      1. A017B8HE01

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

        Standard resistance
        Tester Connection Condition Specified Condition
        2E-12 - 2E-7 No battery voltage applied 10 kΩ or higher
        2E-12 - 2E-7 Battery voltage applied to terminals 2E-10 and 2E-9 Below 1 Ω
        Note:

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

    4. Inspect the C/OPN relay.


      1. A017B8HE02

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

        Standard resistance
        Tester Connection Condition Specified Condition
        2E-13 - 2E-7 No battery voltage applied 10 kΩ or higher
        2E-13 - 2E-7 Battery voltage applied to terminals 2E-8 and 2D-12 Below 1 Ω
        Note:

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

    5. Inspect the A/F relay.


      1. A017B8HE03

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

        Standard resistance
        Tester Connection Condition Specified Condition
        2A-4 - 2C-1 No battery voltage applied 10 kΩ or higher
        2A-4 - 2C-1 Battery voltage applied to terminals 2E-10 and 2E-7 Below 1 Ω
        Note:

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