Intelligent and Traditional Diagnosis

Intelligent Diagnosis reads VIN, accesses diagnostic sessions and reviews history. It supports full-system functions for 97+ brands: version info, fault codes read/clear, data stream, actuator tests, coding and adaptation.

New Energy Diagnostics

Optimized software covers BYD, XPeng, Leapmotor, NETA, Roewe, GAC, BAIC New Energy, Zeekr and more, with over 95% model coverage and continuous updates.

Whole-Vehicle Diagnostics

Battery pack data streams identify fault causes to improve inspection and repair efficiency.

Battery Pack Diagnostics

Reads battery pack info including module count, SOC, SOH and temperature, and deeply reads per-cell voltage and temperature. Supports report generation, sharing and printing.

Remote Diagnosis

SmartLink C is compatible with launch tools, OEM dealer equipment and third-party devices for remote diagnosis. X-431 Remote Diagnosis enables real-time web-based remote vehicle diagnosis with low bandwidth use.

48 Special Functions

Supports 48 common functions including new energy A/C compressor test, coolant replacement, high-voltage power-off, OBC offline test, DC-DC converter test, 48V MHEV test, chip data repair, maintenance light reset, throttle matching, steering angle reset and brake pad reset. The immobilizer programmer is in the toolbox; RESETMVIN multi-VIN detection is in the diagnosis kit.

Toolbox and Diagnosis Kit

The Toolbox integrates 14+ expansion modules such as TPMS tools, ADAS calibration, oscilloscopes, sensors, endoscopes, battery testers, current clamps, insulation testers and key programmers. The Diagnosis Kit provides CAN BUS Pin Detect, CANScope, Firmware Fix, Data Stream Sample, RESET MSVIN, Diagnostic History and more.

Vehicle Coverage, History and Feedback

Supported brands, models, systems and functions can be queried online. Each session auto-generates a diagnostic record. Diagnostic Feedback lets users report issues to LAUNCH for timely support. Know Your Customer helps with opportunity analysis and customer management.

Mall, User Info and Settings

The Mall handles software package purchases, configuration renewals and gateway unlock permissions. User Info manages reports, VCI activation and password reset. SGW gateway unlock for Fiat, Chrysler, Renault and Mercedes-Benz is purchased via the Mall. Settings configure the voice assistant, X key, printing and diagnostic preferences.

AI Features

AI Voice Diagnostics (coming soon, free for a limited time) uses voice intent recognition to reach functions quickly. AI Smart Diagnosis generates a Vehicle Test Report (VTR) with AI fault-code analysis. The AI Workbench provides smart DTC grouping, root-cause analysis and step-by-step repair guidance. Appearance Inspection uses image analysis to detect body damage and auto-generate reports.

Diagnostic Utilities

CAN BUS Pin Detection checks OBD-II pin voltage and protocols. CANScope visually monitors CAN bus data. Diagnostic Plan gives step-by-step fault-guided prompts. Topology Diagram shows the ECU network with communication status and fault codes. High-speed Scan uses multi-channel parallel scanning (integrated into Smart Detection on supported models). VW/Audi Guided Functions require the corresponding passenger vehicle software purchase. Data Stream supports one-click reading, graphical visualization, sampling, marking and playback.
