Scania Diagnos & Programmer 3 (SDP3) v2.65 is the official OEM diagnostic and programming software used by Scania service workshops worldwide. It communicates directly with all Scania vehicle control units via CAN, giving you full read/write access to every ECU system — fault codes, live data, calibrations, parameter adjustments, and ECU software updates.
What You Can Do
- Read & clear fault codes — active and inactive, primary and secondary, with full Fault / Cause / Notes / Action descriptions per code
- Live signal monitoring — real-time data from all sensors and actuators across all ECU systems simultaneously
- Checks & adjustments — activate components, run guided diagnostic wizards, adjust customer parameters
- Calibration — injector calibration, mass flow sensor adaptation, EGR system, variable geometry turbocharger, power take-off
- Built-in circuit diagrams — interactive wiring schematics for every circuit, right-click navigation to components and user functions
- ECU software updates — program new software into control units from local database (offline)
- Spare part programming — configure replacement ECUs with correct SOPS vehicle specification file
- Signal logging — record and export signal data from any ECU server for offline analysis
- Bodywork & conversion — body builder programming and parameter conversions affecting the electrical system
