Heated/Cooled Systems
DESCRIPTION
The heated seat module (HSM) (1) is located under the front passenger seat. It has a single electrical connector (2) and a push-pin retainer that secures it to the seat pan (3). The HSM can be accessed from under the seat.
The HSM is a microprocessor designed to use the Local Interface Network (LIN) data bus messages from the instrument cluster, also referred to as the Cab Compartment Node (CCN). The CCN receives inputs from the heated seat switches and in turn, signals the HSM to operate the heated seat elements for both front seats.
