Dual Pane Sunroof Calibrations

Sunroof initialization & obstacle detection calibration is a process to teach the sunroof/sunshade motor(s) 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 

The following procedure must be followed when one of the below are true:

• Motors have been replaced with new replacement service motors.
• Sunroof will only respond to CLOSE switch (audible motor clicking noise with no motion, sunroof close motion or sunshade close motion when CLOSE switch pressed) & no response to sunroof open/vent & sunshade open/close switch actuation.

1. Set the vehicle ignition to ON/Run or start engine.
2. Push and hold the sunroof glass CLOSE switch. Hold the switch through the following events: sunroof glass will cycle to the closed position (an audible click noise from motor will be heard when full close position achieved), power sunshade will then cycle to closed position (an audible click noise from motor will be heard when full close position achieved), then all motion will stop. Note: If glass and sunshade are already at full closed position at beginning of this procedure only a clicking noise from the sunroof motor followed a clicking noise from the sunshade motor will be heard.
3. Release the sunroof CLOSE switch after all motion has stopped then push and hold it again within 5 seconds. The following sequence of sunroof operations will occur, do not release the switch until the operations are fully completed; the power sunshade will cycle to the full open position, sunroof glass will cycle to full open position and back to closed position, power sunshade will cycle to closed position.
4. Release the switch once all operation stops; initialization and calibration of motors is complete. If the switch is released prior to full completion of the operations described the entire initialization & obstacle detection calibration must be repeated.

Procedure 2: Re-initialization & Obstacle Detection Calibration 

The following procedure must be followed when one of the below are true:

• Original existing motors have been removed and re-installed on the sunroof module.
• Sunshade Assembly, Glass Assembly, Wind Deflector or Seals have been replaced.
• Sunroof glass or sunshade closed position setting incorrect.
• Sunroof Assembly, Glass Assembly, Wind Deflector or Seals have been removed and reinstalled in vehicle.
• Express operation "one touch" is not functioning.
• Sunroof glass or power sunshade is auto-reversing during express close operation with no obstruction blocking sunroof.

1. Set vehicle ignition to ON/Run.
2. Make sure the sunroof is in the closed position.
3. Open front driver side door.
4. Switch vehicle ignition to OFF.
5. Within 5 seconds set vehicle ignition back to ON/Run.
6. Within 10 seconds push and hold the sunroof glass CLOSE switch. After 10 seconds of holding the switch the re-calibration process will be begin. Continue to hold the switch through the following events: the glass will cycle slightly forward into a hard stop then stop (an audible click noise from motor will be heard), the power sunshade will then cycle to CLOSE position and stop (an audible click noise from motor will be heard when full close position achieved).
7. Once the sunroof glass and power sunshade have stopped motion release the sunroof glass CLOSE switch then push and hold it again within 5 seconds. Continue to hold the switch through the following sequence of events, do not release the switch until all operations are fully completed; the power sunshade will cycle to the full open position, sunroof glass will cycle to open position and back to closed position, power sunshade will cycle to closed position.
8. Release the CLOSE switch once all operation stops; re-calibration of motors is complete. If the switch is released prior to full completion of the operations described the entire re-calibration procedure must be repeated from step 1.
9. Confirm sunroof glass and sunshade express operation (press & release switch) is functional for open and close operations.
