Pinpoint Test 6
PINPOINT TEST 6: THE WASHER PUMP IS INOPERATIVENormal Operation
Under normal operation, when the washer is selected, the multifunction switch provides ground to the smart junction box (SJB) through circuit (W/B). Voltage is provided to the washer relay coil and switch through circuit (R). When the SJB commands the washer ON, ground is provided to the washer relay coil through circuit (T/R). When the washer relay is energized, voltage is sent from the washer relay to the washer motor through circuit (B/W). Ground for the washer motor is provided through circuit (B).
Possible Causes
- An open in circuit (B), (T/R), (B/W), (W/B) or (R)
- A short to voltage in circuit (T/R)
- Washer relay
- Washer pump
- Multi-function switch
- Smart junction box (SJB)
