It is primarily used for security code extraction, key programming, and instrument cluster maintenance via the vehicle's OBD-II port. Key Features and Functionality
The software allows users to perform tasks that typically require disassembly or expensive dealership tools. PIN Code Reading
: Extracts security PINs from immobilizers and dashboards to facilitate new key programming. EEPROM Management
: Enables reading and writing to the EEPROM of instrument clusters, useful for repairing corrupted dashboard data. Key Programming
: Users can program new transponder keys directly through the software interface after retrieving the correct PIN. Odometer Correction
: Provides the ability to change mileage counters on supported instrument clusters (Kombiinstruments). Airbag Reset
: Includes a tool for clearing error codes in Airbag control units for specific Opel and VAG models. Автодиагностик Груп Vehicle Compatibility
The tool's effectiveness is highly dependent on the specific electronic control unit (ECU) and dashboard manufacturer. VAG Group (VW/Audi/Seat/Skoda)
