|---|---|---|---|
| STEP | INSPECTION | ACTION | |
| 1 | CHECK CIRCUIT (GY/Y) FOR VOLTAGE
|
Yes | Carry out the driver window control switch component test. See table at the end of this pinpoint test. If the switch tests OK, go to step 3. |
| No | Go to next step. | ||
| 2 | CHECK CIRCUIT (GY/Y) FOR AN OPEN
|
Yes | Install a new SJB. See SMART JUNCTION BOX (SJB) , . Test the system for normal operation. |
| No | Repair circuit (GY/Y) for an open. Test the system for normal operation. | ||
| 3 | CHECK CIRCUIT (BR/L), (Y/V)AND (L/GY) FOR AN OPEN
|
Yes | Install a new driver power window motor. See FRONT DOOR WINDOW REGULATOR AND MOTOR . Test the system for normal operation. |
| No | Circuit (L/GY), repair circuit (L/GY) for an open. Test the system for normal operation. Circuit (BR/L), (Y/V), go to step 4. | ||
| 4 | CHECK CIRCUIT (Y/V) FOR AN OPEN
|
Yes | Go to next step. |
| No | Repair circuit (Y/V) for an open. Test the system for normal operation. | ||
| 5 | CHECK CIRCUIT (BR/L) FOR AN OPEN
|
Yes | Carry out the one-touch down relay component test. See table at the end of this pinpoint test. If the relay tests OK, install a new SJB. See SMART JUNCTION BOX (SJB) , . Test the system for normal operation. |
| No | Repair circuit (BR/L) for an open. Test the system for normal operation. | ||
