3 Headunit
4 Controller�(CON)
5 K-CAN�terminator
6 Touchbox�(TBX)

The�CAN�buses�are�shown�in�the�overview�of�the�bus�systems.�The�actual�physical�layout�(topology)�is
shown�using�the�example�of�the�K-CAN2.
As�with�most�bus�systems,�terminating�resistors�are�also�used�for�protection�of�the�K-CAN�to�avoid
residual�voltages�on�the�data�lines.
The�terminating�resistors�for�the�termination�are�located�in�the:
• Body�Domain�Controller�and
• K-CAN�terminators.
All�other�control�units�are�connected�at�the�K-CAN�terminator�without�a�terminating�resistor.
