Diagnostic Engine

Most tools wait for you
to type in the code.
This one goes and gets it.

Plug in an OBD-II adapter and Lane Pilot works the vehicle itself — deciding what to read next, chasing the modules that answer slow, and telling you straight what it couldn't reach. Then five specialist agents reason over what it actually found and hand back a ranked plan with the one test worth running next.

Multi-Agent Architecture

Five agents. One diagnosis.

Every query triggers a parallel pipeline — not a single API call to a generic model.

CAN Bus Topology

See what’s on the bus. In seconds.

One tap rolls call across the CAN network and renders what answers — online, offline, or throwing errors — plus the modules a secure gateway kept it out of. You’ll know before you touch a wire.

Live Demo

Not a search engine. A specialist.

Every diagnosis shows the evidence it used and the test to run next.

It Runs the Scan Itself
Not a form you fill in. Lane Pilot decides what to read next — unions the capability masks when one module under-reports, escalates to a deeper mode when the first pass comes back thin, and moves on from an ECU that's stalling. Then it tells you which modules never answered.
Next-Best-Test Engine
Active test sequencing. Ranks every open hypothesis and names the physical test that eliminates the most causes per minute of labor. Post the result — the whole list re-ranks.
Waveform Intelligence
Drop a scope capture into the chat — CSV export or a straight screenshot. The engine classifies the signal and folds the evidence into the hypothesis ranking, same turn.
Diagnostic Decision Trees
Every diagnosis generates an interactive flowchart. Pinch-to-zoom on mobile, drag-to-pan, expand fullscreen, and export as PNG for the repair order.
CAN Network Topology
One-tap module roll call. Renders a live spiderweb of what answers on the bus — online, offline, or error — in seconds, and flags what a secure gateway kept it out of. Dead buses and ghost modules called out. No menu diving.
Recall & Repair Evidence
Draws on NHTSA recalls and complaint records, confirmed repair outcomes from other shops, and the scan itself. All makes supported — domestic, Asian, and European.
Web Bluetooth Scanner
Connect a Bluetooth LE ELM327-compatible adapter through the browser (USB and Bluetooth Classic adapters work from a computer). Stream live PIDs, run a Deep Scan, and hand it all to the Diagnostic Engine.
Visual Repair Intelligence
Upload a photo. Get bounding boxes on the components that matter to the diagnosis — severity graded red, yellow, green. Tap a box for the part name and its grade.
PDF Report Export
One-tap branded diagnostic reports with vehicle info, DTCs, analysis steps, and parts tables. Works completely offline. Attach to any repair order.
