An introduction to EOBD Facile on mobile devices and computers.
How the software works
EOBD Facile is automotive electronic diagnostic software that works with ELM327-compatible adapters. It is developed entirely in France by our own team, and its fault code definitions are written in plain English.
Through your vehicle's OBD port, it provides access to diagnostic information such as stored fault codes. The full version also lets you clear eligible codes and reset the check engine light after repairs.
Our software works on all makes of vehicle (Renault, Peugeot, Citroën, Volkswagen, Fiat, Ford, Opel, BMW, Audi, etc.).
Standard OBD does not cover ABS, airbag or ESP systems
With an ELM327 adapter, the software diagnoses engine and transmission control units. To read fault codes and reset ABS, airbag and ESP warning lights on supported vehicles, choose the klavkarr 310.
