Stihl Diagnostic Software 20 -
STIHL Diagnostic Software 20 (SDS 2.0) is the official PC-based tool used by authorized servicing dealers to communicate with electronic engine components on STIHL outdoor power equipment. This software connects to the machine's electronic control unit (ECU) via a specialized MDG 1 or MDG 2 hardware interface. It allows technicians to read operational data, diagnose faults, calibrate systems, and update firmware on modern M-Tronic engines and cordless battery tools. Core Capabilities of STIHL Diagnostic Software 20
+------------------------+ Bluetooth / USB +---------------------+ | Windows Computer | <=======================> | STIHL MDG 1 / ADG 2| | (Running SDS 2.0) | | Diagnostic Unit | +------------------------+ +---------------------+ || || Specialized || Harnesses \/ +---------------------+ | STIHL Power Tool | | (e.g., MS 500i, | | iMOW, BT 131) | +---------------------+ The MDG 1 Analyzer
When starting the software, you can manually check for updates by clicking on the "?" icon in the menu bar and selecting "Check for updates...". If the computer has an internet connection, the software will check for the latest version and, if available, perform the update automatically.
The MDG 1 connects via Bluetooth or USB to the laptop. With the software, it performs:
Turn on the machine's master switch (or wake up the battery) to establish communication. Key Benefits for Servicing Dealers
This is the diagnostic goldmine. While the equipment runs, the software displays:
Verify that your computer meets all the prerequisites listed above.
Displays total operating hours, fuel quality adaptations, and historical maximum RPM counts.
Used when a machine runs poorly after fuel changes or altitude shifts.
Implementing SDS 2.0 into a workshop workflow dramatically changes how equipment is repaired, moving technicians from guesswork to data-driven diagnostics.
