2. Check that the window regulator motor moves smoothly as follows.
   NOTE:

   • Do not apply positive (+) battery voltage to any terminal other than 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 to the door.
   OK
   
   

   Measurement Condition	Specified Condition
   Connect the positive (+) battery terminal to terminal 2 (B), and connect the negative (-) battery terminal to terminal 1 (GND), and keep them connected for 3 seconds or more. With terminals 2 (B) and 1 (GND) connected to the battery, connect the negative (-) battery terminal to terminal 10 (UP). Disconnect and reconnect the negative (-) battery terminal to terminal 10 (UP) within 1 second.	Motor gear rotates clockwise (Up)
   Connect the positive (+) battery terminal to terminal 2 (B), and connect the negative (-) battery terminal to terminal 1 (GND), and keep them connected for 3 seconds or more. With terminals 2 (B) and 1 (GND) connected to the battery, connect the negative (-) battery terminal to terminal 7 (DOWN). Disconnect and reconnect the negative (-) battery terminal to terminal 7 (DOWN) within 1 second.	Motor gear rotates counterclockwise (Down)
