How the AI diagnostic assistant works
Describe the symptoms in plain English — year, make, model, engine, and what the vehicle is doing. The AI researches the specific vehicle, checking for open recalls and technical service bulletins before walking through a structured diagnostic process: information gathering, likely causes, tests to run, and a repair strategy.
Plug in an OBD-II trouble code and the tool explains what it means, common symptoms, probable causes, and verified fixes. Attach a photo or document to the chat and the assistant reviews it as part of the diagnosis.
Guardrails that prevent dangerous guesses
Automotive diagnostics is safety-critical work, so Performance Auto AI enforces strict guardrails: the AI never invents torque specs, part numbers, or repair procedures. Technical data is verified through web research before it reaches you, and anything unverified is clearly flagged so you can confirm it against factory service data.
When a VIN is provided, the diagnostician checks the NHTSA recall database first and surfaces any safety recalls before diagnosis begins — protecting your customer and your shop.
What technicians get
Every diagnostic session is a conversation you can print, save as a PDF, or listen to with text-to-speech — useful when your hands are full in the bay.
- Recall and TSB checks by VIN before diagnosis
- OBD-II code lookup with causes, symptoms, and fixes
- Step-by-step diagnostic procedures and testing order
- Parts lists, special tools, and labor-time estimates
- Voice input — describe the problem hands-free
From diagnosis to invoice
When the diagnosis is done, send the findings straight to the AI estimate generator to price the repair and build a customer-ready quote. The best diagnostic tool is the one that shortens the whole job — from first symptom to paid invoice.
