Synchronization will be necessary anytime the sunroof motor is removed from
the unit. The sunroof module will be synchronized when the controller learns the
full vent position.
To synchronize the sunroof:
- Turn ON the ignition, with the engine OFF.
- Using the close/tilt up portion of the sunroof switch, operate the sunroof
glass until it reaches the full vent position. This may take 20 to 30 seconds.
- Continue to hold the switch in the close/tilt up position for an additional
20 seconds when the glass will make a slight movement indicating the module has been
synchronized.
- Verify that the system operates normally.
Once the sunroof glass reaches the full vent position, the actual position is
stored in the memory of the sunroof module. The module will retain this memory even
after power is removed and restored.
