PINPOINT TEST D: THE WASHER PUMP IS INOPERATIVE

D1-D4:

D4-D6:

Normal Operation
The windshield washer pump is grounded at all times through circuit GD1230 (BK/GY). When WASH mode is selected, the smart junction box (SJB) receives input from the multi-function switch through circuit CRW07 (GY/BN). The SJB then activates the washer pump relay (integral to SJB) which supplies voltage to the washer pump through circuit CRW14 (BU/WH).

Possible Causes
- Open in circuit GD1230 (BK/GY), CRW07 (GY/BN) or CRW14 (BU/WH)
- Multi-function switch
- SJB module
- Windshield washer pump
