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
experience�switch.
The�mirror�servomotors�are�activated�by�the�mirror�electronics.�The�request�for�adjusting�the�exterior
