Seat Heaters
The system for the seat heaters consists of three different parts:
- a Seat Heating Module (SHM) which controls the heater pads and the ventilation fans as well as the function for communicating with the Climate Control Module (CCM) via LIN communication.
- two heater pads
- a temperature sensor.
The Seat Heating Module (SHM) is under the left and right-hand front seat. In some versions, seat heating and seat ventilation rear are also available, in which instance the Seat Heating Module (SHM) is located under the left, respectively, right-hand rear seat. The heater pads are in the seat and backrest. The temperature sensor is in the seat.
The heater pad and temperature sensor are directly connected to the Seat Heating Module (SHM). The Seat Heating Module (SHM) communicates with the Climate Control Module (CCM) via a LIN bus.
There are diagnostics for the seat heating module (SHM).
