The Mercedes OE 374368 is an electronic module WABCO belonging to the EBS4 (Electronic Braking System 4) for industrial vehicles and Mercedes-Benz buses. It is a brake/vehicle dynamics control unit responsible for electronically managing braking, ABS/EBS logic, and communication with other modules on Actros vehicles. The module's function is central to the braking system, as it coordinates the processing of signals from wheel sensors and other inputs in the EBS circuit, commanding the braking response more quickly and accurately than a traditional pneumatic system.

Technical Features

• Electronic control unit: WABCO
• Technical designation: EBS4 Electronic Control Unit
• Electronic management of service braking
• Integration of ABS functions
• Management of stability and traction logic based on vehicle configuration
• Communication with other control units via vehicle data network

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

Functionality

• Electronic management of vehicle braking
• Processing of signals from wheel speed sensors
• Control of ABS functions
• Management of EBS logic with more precise modulation of braking pressure
• Supervision of solenoids and modulators in the braking system
• Interaction with the engine brake or other auxiliary deceleration logics, where provided
• Data exchange with other vehicle systems via electronic network
• Storage of system anomalies
• Support for diagnostics of the electronic braking circuit
• Control of braking behavior based on axle configuration and installed system

Model Applications

• Mercedes-Benz Actros MP4/MP5
