| No |
Repair W/B wire. Clear the DTCs. Test the system for normal operation. |
| 4 |
CHECK POWER TO WASHER PUMP
- Connect all disconnected connectors.
- Disconnect washer pump motor 0919-102.
- Key ON.
- Measure the voltage between washer pump motor connector 0919-102 pin 1, circuit B/W, harness side and ground, while pressing and releasing the washer switch.
- Is the voltage greater than 10 volts with the washer switch pressed, and 0 volts with the washer switch released?
|
Yes |
Go to step 5. |
| No |
Go to step 6. |
| 5 |
CHECK B WIRE AT WASHER PUMP MOTOR FOR AN OPEN
- Key OFF.
- Measure the resistance between washer pump motor connector 0919-102 pin 2, circuit B, harness side and ground.
- Is the resistance less than 5 ohms?
|
Yes |
Replace the washer pump motor.
See WASHER PUMP AND RESERVOIR REMOVAL/INSTALLATION
.
Clear the DTCs. Test the system for normal operation. |
| No |
Repair B wire. Clear the DTCs. Test the system for normal operation. |
| 6 |
CHECK THE WIPER/WASHER RELAY
- Key OFF.
- Disconnect wiper/washer relay from engine compartment fuse box.
- Check the wiper/washer relay. See WIPER/WASHER RELAY COMPONENT TEST
.
- Is the washer pump relay OK?
|
Yes |
Go to step 7. |
| No |
Replace the washer pump relay. Clear the DTCs. Test the system for normal operation. |
| 7 |
CHECK B/W WIRE AT WASHER PUMP MOTOR FOR AN OPEN OR A SHORT TO GROUND
- Measure the resistance between washer pump motor connector 0919-102 pin 1 circuit B/W, harness side and washer pump relay pin 3 circuit B/W, harness side.
- Measure the resistance between washer pump motor connector 0919-102 pin 1 circuit B/W, harness side and ground.
- Is the resistance less than 5 ohms between components, and greater than 10K ohms to ground?
|
Yes |
Go to step 8. |
| No |
Repair B/W wire. Clear the DTCs. Test the system for normal operation. |
| 8 |
CHECK THE VOLTAGE TO THE WASHER PUMP RELAY - R WIRE
- Measure the voltage between washer pump relay pin 5 circuit R, harness side and ground, and between washer pump relay pin 1 circuit R, harness side and ground.
- Are the voltages greater than 10 volts?
|
Yes |
Go to step 9. |
| No |
Repair the appropriate R wire. Clear the DTCs. Test the system for normal operation. |
| 9 |
CHECK CIRCUIT T/R FOR AN OPEN OR A SHORT TO GROUND
- Disconnect SJB connector J-2280a.
- Measure the resistance between washer pump relay pin 1 circuit T/R, harness side and SJB connector J-2280a pin 12 circuit T/R, harness side.
- Measure the resistance between washer pump relay pin 2 circuit T/R, harness side and ground.
- Is the resistance less than 5 ohms between components, and greater than 10K ohms to ground?
|
Yes |
Go to step 10. |
| No |
Repair T/R wire. Clear the DTCs. Test the system for normal operation. |
| 10 |
CHECK T/R WIRE FOR SHORT TO POWER
- Key ON.
- Measure the voltage between washer pump relay pin 1 circuit T/R, harness side and ground.
- Is any voltage indicated?
|
Yes |
Repair T/R wire. Clear the DTCs. Test the system for normal operation. |
| No |
Go to step 11. |
| 11 |
CHECK SMART JUNCTION BOX (SJB) FOR CORRECT OPERATION
- Key OFF.
- Disconnect all the SJB connectors.
- Check for:
- corrosion
- pushed-out pins
- Connect all the SJB connectors and make sure they are seated correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
|
Yes |
Replace the SJB.
See SMART JUNCTION BOX (SJB) REMOVAL/INSTALLATION
.
Clear the DTCs. Test the system for normal operation. |
| No |
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. Clear the DTCs. Test the system for normal operation. |
