How it works

From raw scan to a clear decision.

Whether you have trouble codes, symptoms, or both, the system walks you through a structured diagnostic process and gives you an actionable answer in seconds.

Diagnostic process

Six steps to a diagnosis

1

Add the vehicle

Start with year, make, model, and VIN when available, so the result has the right context.

2

Enter codes or describe symptoms

Single codes, multiple codes, raw text, or symptom-only mode. No scanner required.

3

Describe what you notice

Rough idle, no-start, overheating, poor shifting, reduced power, or intermittent behavior all matter.

4

Get a severity answer

Safe to drive, short trip only, avoid highway, tow recommended, or do not drive.

5

Follow the next steps

Owner checks and shop checks are separated, so you don't replace the first sensor blindly.

6

Share the mechanic brief

Shops see the codes, symptom timeline, likely causes, and test path in one place.

No scanner needed

Symptom-only diagnosis

Don't have a code reader? Just describe what your vehicle is doing. Our AI cross-references symptom patterns against thousands of diagnostic cases to speculate likely root causes, suggest probable codes, and give you comprehensive repair specs.
