WINDSHIELD WIPER MOTOR ASSEMBLY
a. LO Operation Check
1. Connect the battery (+) to the terminal 1 (+1) of the connector, the battery (-) to the 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 the terminal 4 (+2) of the connector, the battery (-) to the 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 the terminal 1 (+1) of the connector, the battery (-) to the 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 the terminal 1 (+1) and 3 (S), and the battery (+) to the terminal 2 (B) to restart the motor operation at low speed (LO).

REAR WIPER MOTOR AND BRACKET ASSEMBLY




a. Operation check
1. Connect the battery (+) to the terminal 1 (+B) of the connector, the battery (-) to the terminal 3 (LS) of the connector and wire harness terminal of the rear wiper motor and bracket assembly, then check that the rear wiper motor and bracket operate.




b. Automatic Stop Position Operation Check
1. Connect the battery (+) to the terminal 1 (+B) of the connector, the battery (-) to the terminal 3 (LS) of the connector and wire harness terminal of the rear wiper motor and bracket assembly. With the motor being rotated disconnect the terminal 3 (LS) from the battery (-), then check that the wiper motor stops automatically to the automatic stop position.
