Wiper Motor Linkage: Testing and Inspection
FRONT WIPER MOTOR AND LINKINSPECTION
1. INSPECT WINDSHIELD WIPER MOTOR ASSEMBLY
(a) Check the LO operation
(1) Connect the battery's positive (+) lead to terminal 1 (+1) and the negative (-) lead to terminal 5 (E), and check that the motor operates at low speed (LO).
OK: Motor operates at low speed (LO).
(b) Check the HI operation.
(1) Connect the battery's positive (+) lead to terminal 4 (+2) and the negative lead to terminal 5 (E), and check that the motor operates at high speed (HI).
OK: Motor operates at high speed (HI).
(c) Check the automatic stop operation.
(1) Connect the battery's positive (+) lead to terminal 1 (+1) and the negative (-) lead to terminal 5 (E). With the motor rotating at low speed (LO), disconnect terminal 1 (+1) to stop the wiper motor operation at any position other than the automatic stop position.
(2) Using SST, connect terminal 1 (+1) and 3 (S). Then connect the battery's positive (+) lead to terminal 2 (+) 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: Refer to illustration.
If the result is not as specified, replace the motor assembly.
