Power Window Motor: Testing and Inspection

Window Motor Initialization

NOTE: Refer to Description and Operation, Intelligent Access with Push Button Start in Antitheft and Alarm Systems to review the procedures for achieving the various ignition states (ignition OFF, ignition in ACCESSORY, ignition ON, ignition START) on vehicles with this feature.

NOTE: Initialization is required to learn both the full up and full down positions and the profile of the glass as it travels through the glass channel. Once initialized, obstacle detection is enabled.

NOTE: A new (original factory setting) or de-initialized window motor will not operate in one-touch up mode until initialized. If a new window motor has been installed, proceed to the initialization procedure.

NOTE: The window motors must be initialized whenever: a new window regulator and motor is installed, a new window glass is installed, a glass top run removal and installation or when carrying out any operation in which grease or lubricants are applied to the window system.

NOTE: If diagnosing a window switch concern, carry out the window initialization procedure before installing a new window switch.

NOTE: All window components (window glass, window regulator, window motor, seals and glass top run) must be installed and tightened to specification before carrying out the initialization procedure.

De-initialization procedure

NOTE: The window motor must be reset to its original factory settings first, then carry out the following de-initialization procedure.

1. Turn the ignition key ON.

2. Operate the window control switch in one-touch mode and remove power from the window motor while the window is moving by one of the following methods:
- Disconnect the vehicle battery cable while the window is moving.

- Disconnect the window motor connector while the window is moving.

- Remove the window motor fuse while the window is moving.

3. This will de-initialize the window motor and reset the window motor to its original factory settings.

4. Re-connect the battery cable, window motor connector or re-install the window motor fuse and carry out the initialization procedure to turn the one-touch up feature on.

Initialization procedure

WARNING: Keep objects and body parts clear of the glass panel when carrying out the initialization procedure. During the initialization procedure, the glass panel closes with high force and cannot detect objects in its path. Failure to follow this instruction may result in serious personal injury.

NOTE: The window must be in the full open position for this procedure to operate correctly.

NOTE: If the initialization procedure is only partially completed, the window motor will remain un-initialized and will not operate in one-touch up mode.

5. Turn the ignition key ON.

6. Activate and hold the window control switch in the up position at the second detent until the window glass stalls for 2 seconds into the glass top run and release the switch.

7. Activate and hold the window control switch in the down position at the second detent until the window glass stalls for 2 seconds at the bottom of its travel and release the switch.

8. Test for correct window operation by carrying out the one-touch up and one-touch down features.
