Initialization And Obstacle Detection Calibration

Sunroof initialization & obstacle detection calibration is the process to teach the sunroof motor where to stop for the correct open, close & vent positions and calibrate the obstacle detection system.

There are two procedures for initialization & obstacle detection calibration. Select the appropriate procedure that fits the scenario. 

PROCEDURE 1: Initialization & Obstacle Detection Calibration 

Procedure 1 must be followed to initialize sunroof and calibrate obstacle detection when one of the following scenarios are true: 

• New replacement service motor has been installed. 
• No sunroof movement when sunroof VENT switch is pressed, express operation (one touch) is no longer functioning, glass only travels less than one inch and stops when OPEN switch is pressed and held, and sunroof glass will only close if sunroof CLOSE switch is pressed and held. 

1. Set vehicle ignition to ACCESSORY or start engine.
2. Press and hold the sunroof CLOSE switch until the sunroof glass panel moves into the vent position then stalls and stops motion.
3. Release the sunroof CLOSE switch, then press and hold it again within 5 seconds, do not release switch.
4. As the sunroof CLOSE switch is held, the sunroof glass panel will move to the fully closed position, then to the fully opened position and then fully closed again.
5. Once all sunroof motion has stopped release the sunroof CLOSE switch, initialization and obstacle detection calibration is complete. Note: If the switch is released prior to the sunroof completing all operations described the entire procedure must be repeated.
6. Confirm sunroof express operation (press & release switch) is functional for open, vent and close operations.
