Sunroof Initialization And Obstacle Detection Calibration
Sunroof initialization and 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.
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.
PROCEDURE 1 - Re-initialization and 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 Assy, Glass Assy, Wind Deflector or Seals have been replaced.
- Sunroof glass or sunshade closed position setting incorrect
- Sunroof Assy, Glass Assys, 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.
If at any point during the following procedures the sunroof does not respond as expected, or the procedure is interrupted, restart the procedure at Step 1.
- Set vehicle ignition to ON/Run.
- Ensure sunroof is in closed position.
- Open front driver side door.
- Switch vehicle ignition to OFF.
- Within 5 seconds set vehicle ignition back to ACCESSORY (ACC) or ON/Run.
- Within 10 seconds push and hold the sunroof glass CLOSE switch (1a) forward. 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).
- 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.
- 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.
- Confirm sunroof glass and sunshade express operation (press & release switch) is functional for open and close operations.
PROCEDURE 2 - Initialization & Obstacle Detection Calibration
The sunroof motors must have the same parameters. This means that parts will send these motors together in a matching set and both need to be replaced together as a set. If the two sunroof motors do not have common parameters, the initialization procedure will not complete.
The following procedure must be followed when one of the below are true:
- One or both 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.
If at any point during the following procedures the sunroof does not respond as expected, or the procedure is interrupted, restart the procedure at Step 1.
- Set the vehicle ignition to ON/Run or start engine.
- Push and hold the sunroof glass CLOSE switch (1a) forward. 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.
- 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.
- 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.
