01
Read the evidence
AutoAll starts with your code, symptoms, and vehicle details to explain what the data suggests—and what it does not prove.
AI-guided car diagnostics
Know what to test before buying parts.
Upload a check-engine code or scanner screenshot. AutoAll turns it into a prioritized diagnostic path—not another vague code definition.
Guidance first. Parts second. No invented certainty.
The AutoAll promise
Built to help you investigate, not panic-buy.
No fake precision
We distinguish likely causes from confirmed faults and explain what evidence is still missing.
Safety stays visible
Reports flag risky symptoms and tell you when diagnosis should move to a qualified professional.
From code to next test
A diagnostic path you can actually follow.
A code like P0171 says the system is running lean. AutoAll helps you find out why.
02
Test likely causes in order
Follow a practical sequence built to rule out common causes before you spend money on parts.
Example sequence for P0171
Review fuel trims → inspect intake leaks → verify MAF readings → check fuel pressure → inspect exhaust leaks → consider parts only after testing.
03

Use the report to keep diagnosing, plan a DIY repair, or have a more informed conversation with a technician.
