The control unit with OE code 4461302040 is the control module of the EBS (Electronic Braking System) installed on the latest generation Mercedes-Benz industrial vehicles such as Actros MP4/MP5.

This 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

• Electronic manufacturer: WABCO.
• Type: EBS control unit / electronic brake ECU for heavy industrial vehicles.
• Power supply voltage: 24 V DC (truck electrical system).
• Housing: die-cast aluminum body with waterproof multipolar connectors.
• Main connections: power and ground, 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.

Functionality

• Complete management of the EBS system: electronic modulation of braking on the various axles of the vehicle.
• 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 logic switches (brake pedal, parking brake, etc.).
• Communication on CAN bus with engine ECU, chassis control unit, cabin control unit, and other safety modules.
• Management of emergency modes in case of failure, activating mechanical backup logic and turning on the EBS/ABS warning lights on the dashboard.

Model applications

• Mercedes Actros MP4/MP5

Typical defects

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

Error Codes

• 060601 - Unit A10B has detected under-voltage or short circuit to ground
• 060604 - Unit A10B has detected under-voltage or short circuit to ground
• 18F0FF - ESP function limitation
• 220303 - Short circuit to positive, ABS solenoids left/right front axle
• 730201 - The power supply of unit A10B is too low
• 75020C - Internal failure

Final conclusions

The EBS Mercedes 4461302040 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 entire electronic architecture of the vehicle. Its proper functioning is essential for safety and braking performance.
