STIHL Diagnostic Software 2.0 (often abbreviated SDS 2.0) is an OEM-level diagnostic and configuration application used by authorized dealers and technicians to interface with modern STIHL professional handheld and power equipment. It provides fault reading/clearing, live data monitoring, ECU programming, firmware updates, parameter adjustments, and guided service procedures for electronically controlled STIHL engines and power heads.

A notable upgrade in SDS 2.0 is its advanced error-handling during firmware updates. If a connection drops during an update, older software versions risked permanently corrupting ("bricking") the control module. SDS 2.0 includes robust fail-safes that can access corrupted, non-responsive electronic modules, rewrite the corrupted sectors, and restore the equipment to working order.
