GF42.45-P-5118MCU ESP Control Unit, Component Description







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 instrument cluster actuates the ABS indicator lamp (A1e17) and ESP warning lamp (A1e41).
