CoreDiag — AI Diagnostics

Works on its own. No Tekmetric required.

CoreDiag is the AI diagnostic tool from AxleOS. It comes with its own repair-order management built in — so you can run the whole thing standalone. No shop management system to buy, no integration project, no IT lift. Open a repair order, describe the concern, and get ranked diagnostic suggestions backed by NHTSA recalls, complaints, and TSBs in seconds.

No integration to configure. A shop is live in minutes.

Standalone by design

Nothing to plug into.
It's the whole tool.

Most "AI add-ons" are bolted onto a shop management system you already pay for. CoreDiag isn't an add-on. It's a complete diagnostic workspace that stands on its own — and connects to Tekmetric only if you want it to.

📝
Built-in repair orders

CoreDiag manages its own ROs — vehicle, customer, concern, jobs. You don't need Tekmetric, Shop-Ware, or any other platform underneath it. Create the RO, get the diagnosis, work the ticket.

🔌
No integration project

Sign up, add your shop, invite your team. There's no API to wire up, no data migration, no vendor approval to wait on. A shop is live in minutes, not weeks.

🚗
Works at any shop

Whatever you run the front office on — even pen and paper — CoreDiag drops in alongside it. Type the vehicle and concern, and your tech gets a head start before the hood is even open.

How standalone works

Three steps.
Start to finish, inside CoreDiag.

01
Open a repair order

Create the RO right in CoreDiag. Enter the vehicle and the customer's concern — VIN decode fills in the rest. No second system to keep in sync.

02
AI analyzes

CoreDiag cross-references NHTSA recalls, complaints, and 949K+ technical service bulletins for that exact vehicle, then returns ranked diagnostic suggestions with confidence and recommended tests.

03
Tech confirms & rates

The tech reviews the suggestion on the RO, runs the tests, and rates the accuracy. That feedback is stored against your shop and makes CoreDiag sharper over time.

Two ways to run it

Standalone first.
Tekmetric when you want it.

Standalone is the default and a complete product on its own. If you already run Tekmetric, CoreDiag can connect — ROs sync automatically and suggestions post back as notes. Same diagnostic engine either way.

Common questions

The standalone questions,
answered.

Do I need Tekmetric to use CoreDiag?
No. CoreDiag includes its own repair-order management and runs completely on its own. Tekmetric Connect is an option for shops that already use Tekmetric — it's never a requirement.
What if my shop runs on something else, or on paper?
That's exactly what standalone is for. You create the repair order inside CoreDiag, get the diagnosis, and work the ticket. It sits alongside whatever your front office already uses.
Where does the diagnostic data come from?
Every suggestion is grounded in NHTSA government data — recalls, owner complaints, and a database of 949K+ technical service bulletins — matched to the exact year, make, and model on the lift, then reasoned over by AI.
Can I start standalone and connect Tekmetric later?
Yes. Start standalone today and switch on Tekmetric Connect whenever you're ready. Your shop, users, and suggestion history carry over — nothing is lost.
How long does setup take?
Minutes. Sign up, add your shop, invite your team, and open your first repair order. There's no integration to configure in standalone mode.
