Tesmec launches the Diagnostic App: instant error code decoding for trencher operators

The free mobile app helps field operators decode machine fault codes in seconds, reducing downtime and improving on-site efficiency.

Tesmec S.p.A. announces the official launch of the Tesmec Diagnostic App, a free mobile application developed to support trencher operators directly in the field. The app is now available for download on iOS, Android and Windows.

Modern Tesmec trenchers display numeric SPN and FMI fault codes on the machine screen. While this system allows for precise fault identification, the corresponding text descriptions were removed from the on-board display to accommodate the increasing complexity of TIER4 engine electronics and the growing number of sensor-generated error codes. Operators were required to consult the machine manual — a document not always available during field operations.

The Tesmec Diagnostic App solves this gap. By entering the SPN and FMI codes displayed on the machine, operators immediately receive the error description, the severity level, the probable cause and the recommended troubleshooting steps — in their preferred language.

Key features:
• Real-time SPN+FMI error code decoding with severity classification
• Guided troubleshooting with probable causes and suggested corrective actions
• Access to Tesmec machine and teeth catalogues
• Direct access to Tesmec Service and Spare Parts contacts
• Insert Request function: users can report missing codes directly to the Tesmec Service team for database update
• Multilingual interface: English, Italian, French, Spanish
• Available for free on iOS, Android and Windows

The app is available for free download on the App Store and Google Play. For technical support or further information, contact: service-trencher@tesmec.com.
