Sunroof Control Module
The sunroof control module is mounted on the rear of the frame, and is connected to the motor at one end as described above, and to the vehicle electrical system at the other. It takes the inputs from the vehicle, such as LIN (Local Interconnect Network) bus signals and switch signals, and controls motor movement appropriately. It also contains the algorithm for the anti-trap system.

NOTE:
Pin 6 is for use in an emergency only in the event of the vehicle LIN bus not being functional. It is not connected on the vehicle harness or in the connector.
NOTE:
Putting pin 6 to ground will enable the sunroof control module but without one touch operation or anti trap. The sunroof will not require re-calibrating unless the battery has been disconnected.
NOTE:
The sunroof control module will remain awake and enabled until pin 6 is disconnected again. Under no circumstances is this pin to be left grounded for long periods.
NOTE:
There is no emergency key access in the headlining for manual sunroof operation should the motor fail for any reason.
