b. Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector and the voltmeter (-) terminal to terminal 2 (EW) of the connector.
2. Connect the battery (+) to terminal 17 (+B) of the connector and the battery (-) to terminal 2 (EW) and 16 (+S) of the connector.
3. Turn the wiper switch to INT.
4. Connect the battery (+) to terminal 16 (+S) of the connector for 5 seconds.
5. Connect the battery (-) to terminal 16 (+S) of the connector. Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 2(EW).




c. Operation Check (Front Wiper)
1. Turn the wiper switch to OFF
2. Connect the battery (+) to terminal 17 (+B) of the connector and the battery (-) to terminal 16 (+S) and 2 (EW) of the connector.
3. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector and the voltmeter (-) terminal to terminal 2 (EW) of the connector. Turn the washer switch to ON and OFF, and check voltage between terminal 7 (+1) and terminal 2 (EW).

2. WINDSHIELD WIPER MOTOR ASSEMBLY




a. LO Operation Check
1. Connect the battery (+) to terminal 1 (+1) of the connector and the battery (-) to terminal 5 (E) of the connector, and check that the motor operates with low speed (LO).

b. HI Operation Check
1. Connect the battery (+) to terminal 4 (+2) of the connector and the battery (-) to terminal 5 (E) of the connector, and check that the motor operates with high speed (HI).

c. Automatic Stop Operation Check
1. Connect the battery (+) to terminal 1 (+1) of the connector and 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 a SST, connect terminal 1 (+1) to 3 (S) and the battery (+) to terminal 2 (B) to restart the motor operation at low speed.

SST 09843-18040




3. Check the automatic stop position.

Standard: See the illustration.

3. REAR WIPER MOTOR ASSEMBLY




a. Operation Check
1. Connect the battery (+) to terminal 1 (+B) of the connector and the battery (-) to terminal 3 (+1) of the connector, and check that the rear wiper motor operates.

NOTE: The body earth should be connected.




b. Automatic Stop Position Operation Check
1. Connect the battery (+) to terminal 1 (+B) of the connector and the battery (-) to terminal 3 (+1) of the connector.

NOTE: The body earth should be connected.

2. With the motor being rotated, disconnect terminal 1 (+B) and terminal 3 (+1) to stop the motor operation at any position except the automatic stop position.
3. Connect the battery (+) to terminal 1 (+B). Check that the motor is restarted and automatically stopped.
