EBS Modulator Trailer Knorr Bremse

Typical Defects:
No communication/diagnosis with the ESP control unit possible
Loss of full functionality, intermittent or permanent
Detected incorrect battery voltage value

Error Codes:
75050C - Internal fault in EBS control unit

The code ES2095 identifies, in the field of commercial vehicles, the TEBS (Trailer Electronic Braking System) G2.2 Premium brake module (Knorr-Bremse) for trailers and semi-trailers. It is a compact unit that integrates the electronic control unit, management of wheel sensors, and the pneumatic section (valves and circuits), electronically controlling the trailer braking and providing functions such as anti-lock, load distribution and stability. It is used, among others, on Mercedes-Benz vehicles.

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

Functions

• Management of the trailer electronic braking with: integrated anti-lock and braking control logics more precise than conventional systems; load-dependent control (electronic load sensing) improving wear and tractor-trailer compatibility; RSP (Roll Stability Program) included as standard equipment in the TEBS G2.2 family
• Support for configurable auxiliary functions (depending on wiring and parameterization), including: management of lift axles (up to two lift-axle valves, depending on the system); speed / speed-switch signals and logics for steering axles; management of specific signals (e.g., tilt angle for tipper applications) via dedicated outputs
• Diagnostics and parameterization: parameter programming and diagnostics via dedicated software, with operator dataset during parameterization (depending on configuration)

Model applications

• Trailers and semi-trailers with the TEBS G2.2 (Premium) system
• Mercedes-Benz Actros MP4/MP5

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:
75050C - EBS control unit internal fault

Final conclusions

The component ES2095 is the TEBS (Trailer Electronic Braking System) G2.2 Premium assembly from Knorr-Bremse for trailers: a central component that combines electronics and pneumatics, enabling advanced configurations (up to 6S3M on suitable variants) and stability functions.
