RELAY ON-VEHICLE INSPECTION

PROCEDURE

  1. INSPECT GLOW PLUG RELAY ASSEMBLY

    1. A372754

      Disconnect the glow plug relay connector.

    2. Detach the clamp and remove the glow plug relay.

    3. A201709N01

      Check the resistance.

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

        Standard Resistance

        Tester Connection

        Condition

        Specified Condition

        1 - 2

        Battery voltage not applied to terminals 3 and 4

        10 kΩ or higher

        Battery voltage applied to terminals 3 and 4

        Below 1 Ω

        If the result is not as specified, replace the glow plug relay assembly.

  2. INSPECT STRTER RELAY (ST)

    1. A291372N01

      Check the resistance.

      1. 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 ST NO. 1 relay.
