Window Motor Initialization

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 LH front window motor will not operate in one-touch up mode until initialized. If a new LH front window motor has been installed, proceed to the initialization procedure.

NOTE: The LH front window motor must be de-initialized, then initialized whenever the LH front window motor is removed from the window regulator assembly, 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: If diagnosing a LH front window switch concern, carry out the window initialization procedure before installing a new 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.

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 LH front 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 LH front window motor fuse and carry out the initialization procedure to turn the one-touch up feature on.

Initialization procedure

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

5. Turn the ignition key ON.

6. Activate the window control switch in the DOWN position and lower the window glass to the full OPEN position.

7. 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.

8. 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.

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