via the OBD-II port. It is widely used by mechanics for reading fault codes, live data streaming, and performing system adaptations on a variety of European, Asian, and American vehicles. Key Specifications & Features Device Type : Single-board diagnostic interface (New VCI). Connectivity : Dual connection options via (for wireless use with tablets/laptops) and Compatibility : Supports most vehicles manufactured after (OBD-II standard). Core Functions Reading and clearing Diagnostic Trouble Codes (DTCs) ISS (Intelligent System Scan) : Automatically scans all vehicle systems. : Real-time monitoring of sensor parameters. Service Resets : Resetting service lights and maintenance intervals. Advanced Tasks : ECU programming, key coding, and component activation. Setup & Bluetooth Pairing
Keeps data parsing fast. Real-time logging requires continuous packet exchanges; the processing core organizes traffic efficiently to avoid timeout drops.
Monitoring sensor data (e.g., engine speed, temperature) via the "Flight Recorder" function. Advanced Procedures:
