Introduction
SANY Diagnostic Tool (SDT) is the official OEM diagnostic platform developed by SANY Heavy Industry for dealers, service engineers and fleet maintenance departments. The software communicates directly with the electronic control units installed on modern SANY machines, allowing technicians to diagnose electronic faults, monitor machine performance, calibrate hydraulic systems, configure controllers and perform software updates using factory-approved procedures.
Modern SANY construction equipment integrates sophisticated electronic control systems for the engine, hydraulics, transmission, safety systems and emissions. SDT provides dealer-level access to these systems, helping technicians reduce troubleshooting time while maintaining equipment according to factory specifications.
What is SANY Diagnostic Tool?
SANY Diagnostic Tool (SDT) is an integrated service application designed for electronic diagnostics and maintenance. Using the official SANY Vehicle Communication Interface (VCI), the software establishes communication with machine controllers, retrieves diagnostic trouble codes, displays live sensor information, performs calibration procedures and supports controller programming.
It is used globally by SANY dealerships, construction companies, rental fleets and professional maintenance workshops responsible for servicing SANY equipment.
