Construction Machinery Computer Diagnostics

Modern construction machinery is managed by advanced controllers (ECU, TCU, VECU). We offer professional computer diagnostics using dedicated service interfaces. We do not just read error codes; primarily, we interpret operating parameters, allowing for an accurate diagnosis without “trial-and-error” parts replacement.

Exhaust Aftertreatment (AdBlue/DPF)

The most common cause of “limp mode” (power reduction) in modern machines are faults in ecological systems.

SCR System (AdBlue)

Verification of the dosing pump, NOx sensors, and tank heaters (a frequent winter fault).

DPF Service

Forced particulate filter regeneration (service regeneration) via computer diagnostic tool.

Sensor Reset

Adaptation of new differential pressure and exhaust temperature sensors after replacement.


Calibrations and Adaptations

After replacing mechanical or hydraulic parts, it is necessary to “teach” the controller the new parameters. We perform:

Transmission Calibration

Setting clutch engagement points.

Injector Adaptation

Coding IMA/QR codes into the engine controller.

Working Hydraulics

Calibration of hydraulic pumps and joysticks.

“Live Data” Analysis

Real-time parameter monitoring allows us to detect faults not visible as error codes:

  • > Common Rail Pressure: LOW [800 bar]
  • > Turbo Boost: OK [1.2 bar]
  • > Hydr. Oil Temp: HIGH [92°C]

What do we do after diagnosis?

A diagnostic report is the basis for further repair. Depending on the verification result, we take appropriate steps:
