ACC control unit

The front power distribution box supplies the ACC control unit with terminal 15N. The ACC control unit is connected to the S-CAN via the Integrated Chassis Management (ICM). The S-CAN transfers the signals at a speed of 500 kBit/s. There are 2 terminating resistors of 120 ohms each for the S-CAN. One terminating resistor is located in the Integrated Chassis Management (ICM). The second terminating resistor is integrated into the ACC control unit.
