INSPECTION PROCEDURE
| 1.CHECK LIN COMMUNICATION SYSTEM |
Check for LIN communication system DTCs related to the power window control system ().
- OK:
- LIN communication system DTCs are not output.
| | GO TO LIN COMMUNICATION SYSTEM ()
|
|
|
Check if DTC B2312 is output ().
- OK:
- DTC B2312 is not output.
| 3.READ VALUE USING INTELLIGENT TESTER (REAR POWER WINDOW REGULATOR MOTOR LH) |
Use the Data List to check if the power window regulator motor is functioning properly ().
RL-Door Motor| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| RL Door P/W Up SW |
Rear power window LH manual up signal / ON or OFF |
ON: Rear power window LH manual up switch operated
OFF: Rear power window LH switch not operated | - |
| RL Door P/W Down SW |
Rear power window LH manual down signal / ON or OFF |
ON: Rear power window LH manual down switch operated
OFF: Rear power window LH switch not operated | - |
- OK:
- The display changes according to operation of the rear power window switch LH.
| OK | |
| |
| REPLACE REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH ()
|
|
| 4.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH LH - BODY GROUND) |
Disconnect the J10 switch connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| J10-1 (GND) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 5.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR MOTOR LH - BATTERY AND BODY GROUND) |
Disconnect the J11 motor connector.
Measure the voltage and resistance according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Condition | Specified Condition |
| J11-2 (B) - Body ground | Always | 11 to 14 V |
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| J11-1 (GND) - Body ground | Always | Below 1 Ω |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 6.CHECK HARNESS AND CONNECTOR (REAR POWER WINDOW REGULATOR SWITCH LH - REAR POWER WINDOW REGULATOR MOTOR LH) |
Disconnect the J10 switch connector.
Disconnect the J11 motor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| J10-6 (UP) - J11-10 (UP) | Always | Below 1 Ω |
| J10-7 (DOWN) - J11-7 (DOWN) | Always | Below 1 Ω |
| J10-8 (AUTO) - J11-4 (AUTO) | Always | Below 1 Ω |
| J10-6 (UP) or J11-10 (UP) - Body ground | Always | 10 kΩ or higher |
| J10-7 (DOWN) or J11-7 (DOWN) - Body ground | Always | 10 kΩ or higher |
| J10-8 (AUTO) or J11-4 (AUTO) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 7.INSPECT REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY LH |
Remove the rear power window regulator switch ().
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Switch Condition | Specified Condition |
| J10-6 (UP) - J10-1 (GND) | Manual up operation | Below 1 Ω |
| J10-7 (DOWN) - J10-1 (GND) | Manual down operation | Below 1 Ω |
| | REPLACE REAR POWER WINDOW REGULATOR SWITCH ASSEMBLY LH ()
|
|
|
| OK | |
| |
| REPLACE REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH ()
