The￿instrument￿cluster￿receives￿the￿value￿of￿the￿ambient￿temperature￿from￿the￿outside￿temperature
sensor￿and￿makes￿this￿available￿via￿the￿PT-CAN.￿The￿Body￿Domain￿Controller￿evaluates￿the￿signal
and￿triggers￿the￿activation￿of￿the￿mirror￿heating￿via￿the￿local￿interconnect￿network￿bus.￿The￿control
of￿the￿heater￿output￿is￿dependent￿on￿the￿ambient￿temperature￿and￿the￿switch￿position￿of￿the￿driving
