Window Motor Initialization - Front

Window Motor Initialization - Front

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: The front window motor must be de-initialized, then initialized whenever the LH front window motor is removed from the window regulator drum housing, a new window regulator is installed, a new window glass is installed, a new top run is installed or for any operation in which grease or lubricants are applied to the window regulator or glass run.

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

NOTE: If diagnosing a LH front window switch problem, perform the window initialization procedure before replacing the window switch.

NOTE: All LH front 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.

NOTE: Excessive bounce-back (window reverses direction with no obstructions present) may indicate that a de-initialization procedure may need to be performed.

De-initialization procedure

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

1. Hold the LH front door open.

2. NOTE: Steps 2 and 3 must be performed within 8 seconds.

Cycle the ignition key from OFF and back to ON 5 times.

3. NOTE: The glass will stop moving after a short distance during this step.

Press the LH front window control switch to the one-touch DOWN position (second detent) and release.

4. Verify that the LH front window does not operate in one-touch up or one-touch down modes. If the window still performs one-touch up/down operations, carefully repeat this procedure.

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 LH front window must be in the full OPEN position for this procedure to operate correctly.

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

5. Hold the LH front door open.

6. Cycle the ignition key from OFF and back to ON 5 times.

7. Press and hold the LH front window control switch until the window glass stalls for one second at the bottom of its travel and release the switch.

8. NOTE: If this operation is interrupted at any time before the window glass stalls into the glass top run, repeat Steps 6 through 8.

Pull and hold the LH front window control switch until the window glass stalls for one second into the glass top run and release the switch.

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