Programming and Relearning




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. This procedure is only required for the LH front window motor.

NOTE: The master window control switch and the LH front window motor each contain integral electronics which must be initialized whenever:
- a new window control switch is installed.
- a new window regulator and motor is installed.
- a new window glass is installed.
- a glass top run removal and installation.
- carrying out any operation in which grease or lubricants are applied to the window system.
- battery voltage has been removed from the LH front window control switch for more than 3 minutes (for example, battery or window control switch disconnected).

NOTE: Before carrying out the initialization procedure, make sure all window components (window glass, window regulator, window motor, seals and glass top run) are installed and tightened to specifications.

1. Turn the ignition ON.

2. 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. While the window is up, repeat this step 2 more times.

3. 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.

4. Test for correct window operation by carrying out the one-touch up/down feature.
