Distronic (DTR) input and output signals - GF30.30-P-0002-02K
The Distronic control unit receives all the information it requires for its calculations over the CAN data bus.
The Distronic uses the engine torque and braking torque interface in the ESP control unit. All requests are first collected in the ESP control unit so that there are no conflicts with engine and brake interventions between the Distronic and ESP systems. The interventions are then executed according to their importance.
