WIPER / WASHER: FRONT WIPER MOTOR: INSPECTION

1. INSPECT WINDSHIELD WIPER MOTOR ASSEMBLY





(a) Check LO operation.

(1) Connect a battery positive (+) lead to terminal 5 (+1) and a negative (-) lead to terminal 4 (E), and check that the motor operates at low speed (LO).

OK:

Motor operates at low speed (LO).

(b) Check HI operation.

(1) Connect a battery positive (+) lead to terminal 3 (+2) and a negative (-) lead to terminal 4 (E), and check that the motor operates at high speed (HI).

OK:

Motor operates at high speed (HI).

(c) Check automatic stop operation.

(1) Connect a battery positive (+) lead to terminal 5 (+1) and a negative (-) lead to terminal 4 (E). With the motor rotating at low speed (LO), disconnect terminal 5 (+1) to stop the wiper motor operation at any position other than the automatic stop position.

(2) Using SST, connect terminals 1 (+S) and 5 (+1). Then connect a battery positive (+) lead to terminal 2 (B) and a negative (-) lead to terminal 4 (E) to restart the motor operation at low speed (LO).

SST : 09843-18040

(3) Check that the motor stops automatically at the automatic stop position.





OK:

Motor stops automatically at the automatic stop position.

If the result is not as specified, replace the motor assembly.
