    2. w/o Intermittent time adjust:

      Intermittent Operation Check

      1. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (-) terminal to terminal 5 (EW) of the connector.
      2. Connect the battery (+) to terminal 8 (+B) of the connector, the battery (-) to terminal 5 (EW) and 6 (+S) of the connector.
      3. Turn the wiper switch to the INT position.
      4. Connect the battery (+) to terminal 6 (+S) of the connector for 5 seconds.
      5. Connect the battery (-) to terminal 6 (+S) of the connector. Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5 (EW).

    1. LO Operation Check
      1. Connect the battery (+) to terminal 1 (+1) of the connector, the battery (-) to terminal 5 (E) of the connector, and check that the motor operates at low speed (LO).
    2. HI Operation Check
      1. Connect the battery (+) to terminal 4 (+2) of the connector, the battery (-) to terminal 5 (E) of the connector, and check that the motor operates at high speed (HI).
    3. Automatic Stop Operation Check
      1. Connect the battery (+) to terminal 1 (+1) of the connector, the battery (-) to terminal 5 (E) of the connector. With the motor being rotated at low speed (LO), disconnect terminal 1 (+1) to stop the wiper motor operation at any position except the automatic stop position.
      2. Using SST, connect terminal 1 (+1) and 3 (S), and the battery (+) to terminal 2 (B) to restart the motor operation at low speed (LO).

        SST 09843-18040

      3. Check the automatic stop position.

        Standard: See the illustration.

    1. Operation Check
      1. Connect the battery (+) to terminal 4 (+1) of the connector, the battery (-) to terminal 1 (-) of the connector, and check that the rear wiper motor operates.
    2. Automatic Stop Position Operation Check
      1. Connect the battery (+) to terminal 2 (+B) of the connector, the battery (-) to terminal 3 (S) of the connector. With the motor being rotated, disconnect terminal 4 (+1) to stop the motor operation at any position except the automatic stop position.
      2. Connect the battery (+) to terminal 2 (+B) to restart the motor operation, then check that the wiper arm blade stops automatically at a certain position. (See REPLACEMENT  )
