Module, Heated Seat: Description: Description
The Heated Seat Module (HSM) (1) is located under the front passenger seat. The HSM has multiple electrical connector outlets (2) and three retaining tabs (3 and 4) that secure it to a bracket that is mounted to the underside of the seat cushion frame.
The HSM is a microprocessor designed to use the Controller Area Network (CAN) data bus messages from the A/C-heater control to operate the front heated seats. When equipped with rear heated seats, the HSM receives request signals from the rear heated seat switches over hard-wired circuits.
