Intelligent Diagnostics Platform
Autel’s Intelligent Diagnostics transforms fault finding from code reading into structured troubleshooting.

Technical Service Bulletins
Manufacturer-issued bulletins are integrated directly into diagnostics.
Covers known issues, recall strategies, DTC patterns, and repair updates.

Repair Assist
Step-by-step guided troubleshooting.
Prioritises tests based on fault probability.
Links directly to wiring diagrams and pin data.

DTC Analysis
Expanded fault interpretation including possible causes and repair direction.

Relevant Cases
Cloud database recommending real-world repair cases matching current DTCs.

Next-Gen Topology 3.0 Diagnostics
Topology 3.0 is not just a CAN Bus tree view. It is a dynamic vehicle communication map.

It visually displays:

All modules on one screen
Network communication structure
Live module status
Color-coded fault status
Direct access to module diagnostics
Why this matters:

Modern vehicles can have 50+ modules communicating across multiple networks. A single fault can trigger secondary DTCs across unrelated systems.

Topology 3.0 allows you to:

Identify primary vs secondary faults
See communication breaks instantly
Detect gateway failures
Reduce diagnostic time significantly
Diagnose complex network faults with precision

ECU Programming & Coding
Offline Coding
Adapt new components such as injectors, keys, steering modules, radios and control units.

Online Coding
Access OEM-level coding and reprogramming when within active update period.

J2534 Pass-Thru Programming
Compatible with OEM subscriptions for flashing and reprogramming via PC/laptop.

Supported with:

BMW, Mercedes-Benz, VAG group, Porsche, Nissan, Infiniti

For other brands, use OEM subscriptions via J2534 interface.

Important: Always use an external battery stabilizer during programming to prevent damage from voltage drops.
