EKK
In�the�eight-pin�signal�connector�the�connections�for�local�interconnect�network�bus,�ground�and�the
12 V�voltage�supply�(terminal�30)�are�integrated.
Special�silencing�in�the�pressure�line�provides�for�further�acoustic�comfort.�The�heating�and�air-
conditioning�is�barely�audible�even�when�the�vehicle�is�at�a�standstill.�The�mechanical�disconnection�of
the�EKK�from�the�electrical�machine�also�improves�the�acoustic�behavior.
