Heated Seat Module - Description

DESCRIPTION





The Heated Seat Module (HSM) (2), also know as the comfort seat wheel module, is located under the driver side front seat. It has a single electrical connector (1) and a push pin style retainer that secures it to the seat pan. The module can be accessed for service from under the driver seat.

The HSM is a microprocessor designed to use the Local Interface Network (LIN) 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 rear door modules over the Controller Area Network (CAN) bus, and in turn, signals the HSM to operate the heating elements for the selected seats.
