Liebherr ECU Manufacturers & Electronic Control Systems

When sourcing a Liebherr ECU, it is important to distinguish between the machine manufacturer and the actual ECU manufacturer.

Liebherr Electronics and Drives

Liebherr-Electronics and Drives GmbH develops and manufactures electronic solutions and control systems for demanding mobile and industrial applications.

Liebherr’s official engine-control range includes:

ECU3
ECU2-HD
Engine control electronics
Injection control systems
Exhaust aftertreatment control
Diagnostic and communication functions

Liebherr identifies its Lindau production site as a specialist facility for customised electronic solutions and electronics for demanding machines.

Bosch

Bosch electronic control units are also encountered in selected Liebherr engine applications. Depending on the machine and engine configuration, Bosch ECU families such as EDC17 may be used.

The actual controller must be identified from the physical unit and machine data before a replacement is supplied.

Liebherr Engine ECU Functions

A Liebherr engine ECU can perform several critical functions depending on the application.

Fuel Injection

The ECU receives information from engine sensors and controls fuel injection to achieve the required engine performance.

Engine Speed & Torque Management

The controller processes engine operating information and manages engine speed and torque according to the machine’s operating requirements.

Engine Protection

The ECU can monitor parameters such as:

Coolant temperature
Oil pressure
Fuel pressure
Engine speed
Intake pressure
Exhaust parameters
Sensor signals
System faults

Exhaust Aftertreatment

Modern Liebherr ECUs can control exhaust aftertreatment systems, including SCR systems and AdBlue/DEF dosing.

CAN-Bus Communication

Electronic controllers communicate with other machine systems through communication networks such as CAN-Bus.

A faulty ECU can therefore create symptoms in several machine systems rather than only causing an engine fault.

ECUs that look similar may have different connector arrangements or internal configurations.

TIP 4 – Check the Engine

Provide the engine model and engine serial number whenever possible.

TIP 5 – Ask Whether Programming Is Required

A replacement ECU may require software, calibration, coding or configuration before the machine will operate correctly.

TIP 6 – Do Not Assume a Used ECU Is Plug-and-Play

A used ECU may contain configuration data from another machine.

TIP 7 – Compare Hardware and Software Numbers

Where possible, compare both the hardware identification and software/calibration information.

TIP 8 – Investigate the Original ECU Failure

If the original ECU failed because of a wiring short, power-supply problem, water ingress or sensor fault, the underlying problem should be investigated before installing another controller.
