WASHER PUMP IS INOPERATIVE - PINPOINT TEST REFERENCE
| PINPOINT TEST 6 | THE WASHER PUMP IS INOPERATIVE | ||
|---|---|---|---|
| STEP | INSPECTION | ACTION | |
| 1 | RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCs)
|
Yes | If DTC B1458, carry out the washer relay component test. See table at the end of test. If the relay tests OK, go to next step. If DTC B1460, go to step 4. |
| No | Carry out the washer relay component test. See table at the end of test. If the relay tests OK, go to step 5. | ||
| 2 | CHECK THE VOLTAGE TO THE WASHER PUMP RELAY COIL
|
Yes | Go to next step. |
| No | Repair circuit (Y) for an open. Test the system for normal operation. | ||
| 3 | CHECK CIRCUIT (L/W) FOR AN OPEN
|
Yes | Go to step 10. |
| No | Repair circuit (L/W) for an open. Test the system for normal operation. | ||
| 4 | CHECK CIRCUIT (L/W) FOR A SHORT TO VOLTAGE
|
Yes | Repair circuit (L/W) for a short to voltage. Test the system for normal operation. |
| No | Go to step 10. | ||
| 5 | CHECK THE VOLTAGE TO THE WASHER PUMP RELAY SWITCH
|
Yes | Go to next step. |
| No | Repair circuit (Y) for an open. Test the system for normal operation. | ||
| 6 | CHECK THE WASHER PUMP
|
Yes | Carry out the multi-function switch component test. See table at the end of test. If the switch tests OK, go to step 9. |
| No | Go to next step. | ||
| 7 | CHECK THE GROUND TO THE WASHER PUMP MOTOR
|
Yes | Go to next step. |
| No | Repair circuit (B/GY) for an open. Test the system for normal operation. | ||
| 8 | CHECK CIRCUIT (GY) FOR AN OPEN
|
Yes | Install a new washer pump. See WINDSHIELD WASHER PUMP AND RESERVOIR -- 3.0L AND 4.0L or WINDSHIELD WASHER PUMP AND RESERVOIR -- 2.3L . Test the system for normal operation. |
| No | Repair circuit (GY) for an open. Test the system for normal operation. | ||
| 9 | CHECK CIRCUIT (W/B) FOR AN OPEN
|
Yes | Go to next step. |
| No | Repair circuit (GY/BR) for an open. Test the system for normal operation. | ||
| 10 | CHECK FOR CORRECT SJB OPERATION
|
Yes | Install a new SJB. See
SMART JUNCTION BOX (SJB)
,
. Clear the DTCs, Repeat the self-test. |
| No | The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test. | ||
