Know if it is minor or tow-now serious
Every result includes severity and driveability guidance so you can separate a monitor fault from a stop-driving risk. Get repair specs detailed enough to DIY or educate yourself before the shop visit.
Diagnostic-first platform
Upload your scan, get the issue in plain English.
Check Engine Help turns raw codes and symptoms into a clear action plan, a driveability answer, and a mechanic-ready summary without pretending every code means a part is bad.

How it works
Three steps to a clear diagnosis
1
Enter codes or symptoms
Type your trouble codes, describe what the vehicle is doing, or both. No scanner required for symptom-only diagnosis.
2
AI analyzes everything
The engine cross-references codes, symptom patterns, and vehicle-specific data to find the real root cause.
3
Get a clear action plan
Severity, driveability, likely causes, next steps, and a mechanic-ready brief. No guessing, no parts darts.
Start with evidence, not parts darts
Code clusters, symptom context, and ranked causes keep the conversation centered on confirmatory testing. Mechanic briefs give techs a head start.
No scanner? Describe what you hear and feel
Enter symptoms like "rough idle, gas smell, poor mileage" and the AI speculates likely codes and root causes. Works with or without a code reader.
