The system for the seat heaters consists of three different parts:

The seat heating module (SHM) is under the left and right-hand front seat. The heater pads are in the seat and backrest. The temperature sensor is in the seat.

The seat heating module (SHM) is directly connected to the heater pad and temperature sensor. 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).
