Product Features:
1. Hardware Performance Upgrade
The adapter's performance has been significantly enhanced: its CPU has been upgraded from a single-core to a dual-core processor, with the clock speed increased to 1.7 GHz. The RAM has been expanded from 256 MB to 1 GB, greatly accelerating computational response speed and making instruction execution more efficient. The CAN bus has been upgraded to 4‑way CAN FD, comprehensively improving communication bandwidth and transmission capabilities to meet the diagnostic requirements of more new vehicle models.
2. Diagnostic Function Upgrades
Visualized Diagnostic Functions: Supports graphical display of special functions, topology diagrams, and data streams. Data trends are intuitively visible, enabling more precise and efficient fault pinpointing, and eliminating the tedious interpretation of plain text.
High-Speed Scanning: Adopts multi-channel synchronous scanning technology to process diagnostic tasks in parallel. Compared with traditional single-channel scanning, it significantly improves efficiency, delivers faster diagnostic speed, and saves repair time.
AI Fault Repair: Visually displays fault points and provides targeted, highly feasible optimization solutions.
Product Highlights:
Read Data Stream: Offers various data stream display modes and enables users to set custom standard data streams.

Graphical visualization of special functions: Covers D&P&F, APS system, urea injection, cylinder cut‑off detection, injector coding, suspension, clutch, and other functions, with intuitive display of dynamic vehicle data.
Special Functions: Supports commonly used special functions for most vehicle models, including D&P&F regeneration, parameter setting, cylinder cut‑off compression test, service reset, injector programming, speed limit adjustment, idle speed adjustment, fan calibration, remote throttle, urea injection drive, deep DTC clearing, transmission adaptation, NOx sensor, and others – covering a total of 18 special functions, with continuous updates.
AI Fault Repair: Intuitively pinpoint fault locations and deliver targeted, highly feasible optimization solutions
High‑Speed Diagnosis: Equipped with multi‑channel detection technology, it significantly improves operational efficiency and represents a major upgrade to vehicle diagnostic functions.
