The Power Sunroof and Sunshade System consists of the following components:

Battery positive voltage is supplied at all times to the sunroof control module and sunshade control module from the 30 A S/ROOF/SUNSHADE Fuse located in the underhood fuse block. Ground is supplied to the sunroof and sunshade module through the body ground circuit G402.

Ground is supplied to the sunroof and sunshade switch through the body ground circuit G402.

The Power Sunroof System will operate only with the ignition turned to the RUN or Accessory positions, this allows for retained accessory power (RAP) control of the sunroof and sunshade through the body control module (BCM). With the ignition in the run or accessory positions, the BCM supplies the sunroof and sunshade with ignition voltage which allows sunroof and sunshade operation. Once the ignition switch is turned to OFF the sunroof will continue to operate until any door is opened or when the RAP timer reaches its shut-off limit. For a description and operation of the RAP operation, refer to Retained Accessory Power (RAP) Description and Operation.

The sunroof and sunshade switch assembly contains two rocker type switches that are used to control the following functions:

The sunroof and sunshade module assemblies have bi-directional motors. The motors ground is removed when the sunroof or sunshade reaches the soft stop end of travel position. This is based on the learned position that was performed during the initialization process. The internal hall effect sensors within the sunroof and sunshade control module assemblies create pulses that are counted by the modules until the end of travel position is reached.
