Theory Of Operation
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The Comfort Seat Wheel Module (CSWM) controls the Vented Seat motor in each seat cushion and seat back. It receives requests via CAN - IHS Bus from the Body Control Module (BCM) and provides outputs to the designated Vented Seat motor. The Vented Seat motors are powered by a fuse located in the Power Distribution Center (PDC) assembly. The Vented Seat motors operate with a low side driver supplied by the CSWM.
