POWERED BY DYNAMIC DIAG · REASONING ENGINE
Diagnose faults
without the guesswork.
Enter the year, make, model, complaint and any DTCs. Dynamic Diag walks you through a targeted test procedure — step by step — until you have a root cause and a repair plan. Built for working technicians, not armchair mechanics.
AI Root-Cause Engine
Our reasoning engine works through the case like a shop foreman and ranks the likely causes before you touch a wrench.
Adaptive Flow Chart
Every answer you give reshapes the diagnostic path so you always test the highest-information-gain node next.
Real Test Procedures
Tools required, expected values, and safety warnings for every step. No fluff. Just what to check and how.

Confidence
HIGH
Customer Complaint
Engine misfires when warm, rough idle, check engine light on.
Observations / DTCs
DTC: P0302, P0316. Fuel trim +18% at idle. Plugs look OK.
03
Confirmed Root Cause
Faulty Cylinder 2 Ignition Coil
04
What This Means (Plain English)
The part that fires the spark plug on one of your engine's cylinders failed. That's why the engine shook at idle and the check engine light came on. Replacing that single coil restores smooth running.
