Wiper Motor and Switch
INSPECTION1. WINDSHIELD WIPER SWITCH ASSY
a. Continuity Check
1. Check the continuity of each terminal of the connector.
b. 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).
c. W/ 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).
d. Operation Check (Front Wiper)
1. Turn the wiper switch to the OFF position.
2. Connect the battery (+) to terminal 8 (+B) of the connector, the battery (-) to terminal 6 (+S) and 5 (EW) of the connecter.
3. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (-) terminal to terminal 5 (EW) of the connector. Turn the washer switch to ON and OFF and check voltage between terminal 7 (+1) and terminal 5 (EW).
2. WINDSHIELD WIPER MOTOR ASSY
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 at 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 at 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 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.
3. REAR WIPER MOTOR ASSY
a. 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.
b. Automatic Stop Position Operation Check
1. Connect the battery (+) to terminal 2 (+B) of the connector, the battery (-) to terminal 3 (5) 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.
