Land Rover Defender: Door Window Motor Initialization

GENERAL PROCEDURES

NOTES:

• Make sure that the vehicle battery is fully charged before carrying out this procedure.
• After the battery has been disconnected or a new window regulator and motor or door module has been installed, it is necessary to initialize each door window motor separately to operate the one-touch and anti-trap function.
• In addition to this manual procedure, the approved diagnostic tool can also be used to initialize the door window motor.

1. Start the engine.

2. Operate the window control switch until the door window glass is in the fully closed position, continue to operate the window control switch for a further two seconds.

3. Release the window control switch.

4. Operate the window control switch in the closed position and continue to operate the window control switch for a further two seconds.

5. Operate the window control switch until the door window glass is in the fully open position ( one-touch down).

6.

NOTES:

• If the door window motor initialization has been completed correctly, when the window control switch is operated, the door window glass should move to the fully closed position ( one-touch up) automatically.
• If the door window glass does not fully close automatically ( one-touch up), repeat the complete procedure.

Operate the window control switch once to the close position.

If multiple attempts have failed to initialize the door window motor, refer the diagnosis and testing procedure.

7. Repeat the door window motor initialization for each door window motor.
