Test D: The Washer Pump Is Inoperative
PINPOINT TEST D: THE WASHER PUMP IS INOPERATIVENormal Operation
The windshield washer pump is grounded at all times through circuit GD123 (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).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multi-function switch
- SJB module
- Windshield washer pump
