The control unit with OE code A0014460536 is the control module of the EBS (Electronic Braking System) installed on Mercedes-Benz Actros 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 multi-pin 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.

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 logic switches (brake pedal, parking brake, etc.).
• Communication over CAN bus with the engine ECU, chassis control unit, cab control unit and other safety modules.
• Management of emergency modes in case of failure, activating mechanical backup logic and illuminating EBS/ABS warning lights on the instrument cluster.

Model applications

• Mercedes Actros MP4/MP5

Typical faults

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

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 solenoid valves left/right front axle
730201 – Power supply of unit A10B is too low
75020C - Internal fault

Final conclusions

The Mercedes EBS control unit A0014460536 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.
