NOTICE:

Do not apply positive (+) battery voltage to any terminals other than terminal 2 (B) to avoid damaging the pulse sensor inside the motor.

(b) Connect a ground lead to connector terminals 1 (GND) and 7 (DOWN) or 10 (UP).

(c) Check that the motor gear rotates smoothly as follows:

Measurement Condition

Specified Condition
  1. Connect a positive (+) battery lead to terminal 2 (B), connect a negative (-) battery lead to terminal 1 (GND), and keep them connected for 3 seconds or more.
  2. With terminals 2 (B) and 1 (GND) connected, connect a negative (-) battery lead to terminal 10 (UP).
  3. Disconnect and reconnect a negative (-) battery lead to terminal 10 (UP) within 1 second.

Motor gear rotates clockwise
  1. Connect a positive (+) battery lead to terminal 2 (B), connect a negative (-) battery lead to terminal 1 (GND), and keep them connected for 3 seconds or more.
  2. With terminals 2 (B) and 1 (GND) connected, connect a negative (-) battery lead to terminal 7 (DOWN).
  3. Disconnect and reconnect a negative (-) battery lead to terminal 7 (DOWN) within 1 second.

Motor gear rotates counterclockwise
  • If the result is not as specified, replace the power window regulator motor assembly LH.

CAUTION:

Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator onto the door.
