The control unit with OE code 4461300290 is the control module of the EBS (Electronic Braking System) installed on Mercedes-Benz Arocs commercial vehicles.

It is a brake control unit that electronically manages braking, the ABS/ASR functions, the trailer brake EBS and communication with other vehicle control units via the CAN network.

Technical specifications

• Type: EBS control unit / electronic brake ECU for heavy commercial vehicles.
• Supply voltage: 24 V DC (truck electrical system).
• Housing: die-cast aluminum body with sealed multipolar connectors.
• Main connections: power and grounds, ABS wheel speed sensors, pressure sensors, brake circuit solenoid valves, EBS trailer control valve, CAN line to other ECUs.

DIPA can intervene to overhaul these components thanks to its experience and expertise.

Functions

• Complete management of the EBS system: electronic modulation of braking across the vehicle's axles.
• Integrated ABS/ASR functions: wheel-lock and traction control via wheel speed sensors and brake solenoid valves.
• Control of the EBS trailer brake via a dedicated control valve and signal lines to the semi-trailer.
• Acquisition of signals from wheel sensors, pressure sensors and logical switches (brake pedal, parking brake, etc.).
• Communication on the CAN bus with the engine ECU, chassis control unit, cab control unit and other safety modules.
• Management of emergency modes in case of fault, with activation of mechanical backup logics and illumination of EBS/ABS warning lights on the instrument panel.

Model applications

• Mercedes Arocs

Typical faults

• No communication/diagnosis with the ESP control unit possible
• Loss of complete functionality, intermittent or permanent
• Detected incorrect battery voltage value

Error Codes:
060601 – Unit A10B detected undervoltage or short to ground
060604 – Unit A10B detected undervoltage or short to ground
18F0FF - ESP function limitation
220303 - Short to positive, ABS solenoids left/right front axle
730201 – The power supply of unit A10B is too low
75020C - Internal fault

Final conclusions

The EBS Mercedes 4461300290 control unit is the heart of the electronic braking system on modern Mercedes trucks: it integrates ABS, EBS, trailer brake management and communication with the vehicle's entire electronic architecture. Its correct operation is essential for braking safety and performance.
