FAULT CODE DIAGNOSTICS
Scan and clear DTC (Diagnostic Trouble Code) fault codes directly from your vehicle's ECU. Each code comes with a plain-English explanation, severity level (Critical / Warning / Info), and possible causes so you know exactly what is wrong before visiting a mechanic.
AI MECHANIC (Pro)

Unlock hidden features in your vehicle's ECU. Fold mirrors on lock, enable needle sweep animations, disable speed limiters, and more. Includes dedicated coding profiles for more than 15 popular vehicle brands.
VEHICLE AUTO-DETECTION
