Location 

The regenerative braking system control unit is located on the hydraulic unit traction system in the left front of the engine compartment.

Task 

General 

The regenerative braking system is a modular designed brake and vehicle dynamics control system (in case of errors only affected functions are switched off). The regenerative braking system is a further development of the Electronic Stability Program (ESP) and also contains the ESP functions.

Flashing 

The regenerative braking system control unit is flashable i.e. the complete software in the control unit can be updated (replaced). The software required to update the control units is stored on the STAR DIAGNOSIS DAS Update DVD.

CAN data bus 

The regenerative braking system control unit is connected through the engine compartment CAN (CAN C) and the vehicle dynamics CAN (CAN H) to the vehicle's CAN network and exchanges data with other control units.

Input and output signals 

The following input signals are evaluated by the regenerative braking system control unit and the corresponding output signals issued:

Direct input signals
