Turn complex faults into guided, standardized repairs — without depending on your most experienced technician.
Goes beyond reading a DTC. Gmate interprets the
meaning behind the code, drawing on the Vehicle
Fault Knowledge Graph to explain what actually
went wrong.
Pinpoints the true source of a fault instead of its
symptoms — reducing misdiagnosis, repeat repairs,
and wasted parts.
Delivers a step-by-step repair route built on
hundreds of thousands of real-world cases, so any
technician can work to expert-level standards.
Built on the X-Cloud global knowledge base and
large language model reasoning — consistent
results across every bay, every shift, every
skill level.
XTOOL's next-generation Integrated Diagnostic System embeds a dedicated AI Agent with Model Context Protocol (MCP) support — giving AI real-time access to diagnostic toolchains, vehicle data, and cloud knowledge, all under full contextual awareness.
One diagnostic platform across
R&D, production-line testing, and
aftersales — with a competitive
total cost of ownership and full
international standards
compliance (ODX, OTX, D-Server,
D-PDU, ISO 22900-2/3).
Industrial-grade diagnostic
capability on every device,
continuously updated
from the cloud — fewer
unsupported vehicles, faster
new-model coverage.
AI-assisted diagnostics, fault
trend prediction, and remote
expert collaboration, drawing
on 99% mainstream global
vehicle coverage.
Three industry-first innovations, now adopted as de facto standards across the global EV service market.
The challenge: Diagnosing a removed battery pack traditionally required reinstallation — time-consuming and costly.
XTOOL’s solution: Read fault codes, voltage, and temperature data directly from the battery in its off-vehicle state,
using XTOOL’s proprietary protocol parsing technology.
The result: Full battery diagnostics without reinstallation — significantly reducing repair time and cost.
The challenge: High-voltage component faults are hard to isolate; without pre-installation verification, rework is inevitable and expensive.
XTOOL’s solution: Built-in CC/CP signal simulation drives high-voltage components — compressors, DC/DC converters, OBC — to full
operation in their off-vehicle state for complete functional verification.
The result: Eliminate trial-and-error repairs. Verify before you install.
The challenge: After a power-loss event, the BMS locks the protection board. OEMs typically require full battery
pack replacement — at prohibitive cost.
XTOOL’s solution: Chip-level data rewriting using built-in standard battery data, a programmer, and visual wiring
diagrams. One-click recovery unlocks the protection board without pack replacement.
The result: Avoid full battery assembly replacement. Dramatically lower repair costs. Any technician can execute it.
Every certification below is a commitment — to quality, safety, and your confidence in XTOOL as a long-term technology partner.
