|
| ||||
OK | |
3.READ VALUE USING TECHSTREAM (DRIVER SIDE MOTOR) |
Use the Data List to check if the driver side motor is functioning properly.
D-Door Motor Tester Display Measurement Item/Range Normal Condition Diagnostic Note D Door P/W Up SW Driver side power window MANUAL UP switch signal / ON or OFF ON: Driver side switch operated
OFF: Driver side switch not operated- D Door P/W Down SW Driver side power window MANUAL DOWN switch signal / ON or OFF ON: Driver side switch operated
OFF: Driver side switch not operated-
- OK:
- The Techstream display changes normally when master switch is operated.
|
| ||||
OK | ||
|
4.CHECK HARNESS AND CONNECTOR (MASTER SWITCH - BATTERY AND BODY GROUND) |
Disconnect the N2 master switch connector.
Measure the voltage and resistance according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Switch Condition Specified Condition N2-3 (B) - Body ground Always 11 to 14 V N2-13 (B) - Body ground Ignition switch ON 11 to 14 V
- Standard Resistance:
Tester Connection Condition Specified Condition N2-1 (E) - Body ground Always Below 1 Ω
|
| ||||
OK | |
5.CHECK HARNESS AND CONNECTOR (DRIVER SIDE MOTOR - BATTERY AND BODY GROUND) |
Disconnect the N12 motor connector.
Measure the voltage and resistance according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition N12-2 (B) - Body ground Always 11 to 14 V
- Standard Resistance:
Tester Connection Condition Specified Condition N12-1 (GND) - Body ground Always Below 1 Ω
|
| ||||
OK | |
6.CHECK HARNESS AND CONNECTOR (MASTER SWITCH - DRIVER SIDE MOTOR) |
Disconnect the N2 master switch connector.
Disconnect the N12 motor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition N2-4 (UP) - N12-10 (UP) Always Below 1 Ω N2-5 (DOWN) - N12-7 (DOWN) Always Below 1 Ω N2-4 (UP) - Body ground Always 10 kΩ or higher N2-5 (DOWN) - Body ground Always 10 kΩ or higher
|
| ||||
OK | |
7.INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH |
Remove the driver side motor (Click here).
Apply positive (+) battery voltage to connector terminal 2 (B).
- NOTICE:
- Do not apply positive (+) battery voltage to any terminals except terminal 2 (B) to avoid damaging the pulse sensor inside the motor.
- Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly to the door.
Apply negative (-) battery voltage to connector terminals 1 (GND) and 7 (DOWN) / 10 (UP).
Check that the motor gear rotates smoothly as follows.
- OK:
Measurement Condition Specified Condition Battery positive (+) → 2 (B)
Battery negative (-): 1 (GND) (3 sec. or more) → 1 (GND) and 10 (UP) (within 1 sec.) → 1 (GND) (within 1 sec.) → 1 (GND) and 10 (UP)Motor gear rotates clockwise Battery positive (+) → 2 (B)
Battery negative (-): 1 (GND) (3 sec. or more) → 1 (GND) and 7 (DOWN) (within 1 sec.) → 1 (GND) (within 1 sec.) → 1 (GND) and 7 (DOWN)Motor gear rotates counterclockwise
