Sunroof Motor And Module Initialization

SUNROOF MOTOR AND MODULE INITIALIZATION

INITIALIZATION

A new motor is shipped uncalibrated with no vehicle cycles having been run. After installation and connection of the wire harness, the following steps must be taken to initialize the new motor and module unit.

NOTE: Verify that the battery is in good condition prior to performing this procedure. Do not leave the vehicle on a battery charger while performing this procedure. If the voltage at the sunroof motor and module unit drops below 11 volts or exceeds 15 volts at anytime while this procedure is being performed, the motor and module initialization procedure will not be properly completed.

NOTE: If at any point during the following procedure the sunroof does not respond as expected, restart the procedure at Step 1.

1. Depress and hold the CLOSE push button of the sunroof switch until the sunroof sliding glass panel moves to the fully closed hard stop and then back to the tilt (VENT) position.
2. Release the CLOSE push button of the sunroof switch, then depress and hold the CLOSE push button again within 5 seconds.
3. As the CLOSE push button of the sunroof switch is held, the sunroof sliding glass panel will move to the fully closed position, then to the fully opened position and then fully closed again.
4. Initialization is complete. Release the sunroof switch push button.

REINITIALIZATION

The following procedure causes a previously calibrated and properly operating electronic motor module to relearn and update motor stall position and obstacle detection.

NOTE: If at any point during the following procedure the sunroof does not respond as expected, restart the procedure at Step 1.

1. Depress and hold the CLOSE push button of the sunroof switch until the sliding glass panel is fully closed.
2. Continue to hold the CLOSE push button of the sunroof switch. It will take at least 10 seconds for the initialization process to begin.
3. The sunroof sliding glass panel will move to the hard stop and then back to the tilt (VENT) position.
4. Release the CLOSE push button of the sunroof switch, then depress and hold the CLOSE push button again within 5 seconds.
5. As the CLOSE push button of the sunroof switch is held, the sunroof sliding glass panel will move to the fully closed position, then to the fully opened position and then fully closed again.
