Heated Seat Module - Description






DESCRIPTION





The Heated Seat Module (HSM) (1), also known as the comfort seat wheel module, is a microprocessor designed to use Controller Area Network (CAN) data bus messages from the instrument cluster, also known as the Cabin Compartment Node (CCN). The CCN receives inputs from the heated seat switches and in turn, requests the HSM to operate the heated seat elements for both front seats.

The HSM has multiple electrical connector outlets (2) and three retaining tabs (3 and 4) that secure it to a bracket mounted to the underside of the front passenger seat.
