1
Hydraulic unit
N47-5
ESP control unit
Location
The ESP control unit is located on the hydraulic unit on the vehicle underfloor.
Task
The ESP control unit controls the following systems:
^
Electronic Stability Program (ESP)
^
Acceleration Slip Regulation (ASR)
^
Engine braking regulation (EBR)
^
Antilock brake system (ABS)
^
Electronic brake force distribution (EBV)
Communication and influence of ESP control unit on other systems in the vehicle:
^
The ESP control unit influences the engine management and power transmission in the case of an ESP control.
^
For driver information the control unit actuates the instrument cluster via the Controller Area Network (data bus/CAN bus) (CAN)A1), the
