      Component without harness connected

      (Windshield Wiper Motor Assembly)

      Check the LO operation.

      1. Connect the positive (+) lead of the battery to terminal 1 (+1) and the negative (-) lead to terminal 5 (E), and then check that the motor operates at low speed (LO).

        OK

        The motor operates at low speed (LO).

    3. E184712C02

      *a

      Component without harness connected

      (Windshield Wiper Motor Assembly)

      Check the HI operation.

      1. Connect the positive (+) lead of the battery to terminal 4 (+2) and the negative (-) lead to terminal 5 (E), and then check that the motor operates at high speed (HI).

        OK

        The motor operates at high speed (HI).

    4. E184712C03

      *a

      Component without harness connected

      (Windshield Wiper Motor Assembly)

      Check the automatic stop operation.

      1. Connect the positive (+) lead of the battery to terminal 1 (+1) and the negative (-) lead to terminal 5 (E). With the motor operating at low speed (LO), disconnect terminal 1 (+1) to stop the wiper motor operation at any position other than the automatic stop position.

      2. Using SST, connect terminals 3 (+S) and 1 (+1). Then connect the positive (+) lead of the battery to terminal 2 (B) and the negative (-) lead to terminal 5 (E) to restart the motor operation at low speed (LO).

      3. Check that the motor stops automatically at the position where the matchmarks align.

        OK

        The motor stops automatically at the position where the matchmarks align.

        If the result is not as specified, replace the windshield wiper motor assembly.
