1. Check for LIN communication system DTCs related to the power window control system. Refer to HOW TO PROCEED WITH TROUBLESHOOTING .

   OK

   LIN communication system DTCs are not output.

NG → See step   10 

OK: Go to next step 

1. Check if DTC B2312 is output. Refer to DTC CHECK / CLEAR .

   OK

   DTC B2312 is not output.

NG → See step   11 

OK: Go to next step 

1. Use the Data List to check if the driver side motor is functioning properly.

2. 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

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the N12 motor connector.

2. 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

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR

2. Disconnect the N12 motor connector.
3. 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

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the driver side motor. Refer to REMOVAL .

2. Apply positive (+) battery voltage to connector terminal 2 (B).
   NOTE:

   • 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.
3. Apply negative (-) battery voltage to connector terminals 1 (GND) and 7 (DOWN) / 10 (UP).
4. 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

OK → See step   9
