INSPECTION1. WINDSHIELD WIPER SWITCH ASSEMBLY
a. Continuity Check
1. Check the continuity of each terminal of the connector.
Front Wiper Switch
Rear Wiper Switch
Front Washer Switch
Rear Washer Switch
b. Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (-) terminal to terminal 2 (EW) of the connector.
2. Connect the battery (+) to terminal 17 (+B) of the connector, 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, the battery (-) to terminal 16 (+5) 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, 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, 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, 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) and 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 4 of the rear wiper motor assembly, the battery (-) to terminal 5 of the rear wiper motor assembly. Check that the motor turns clockwise.
2. Reverse the polarity, and check that the motor turns counterclockwise.
