This simple diagnostic is billed around 50 dollars, in addition of potential repairs which it is difficult to evaluate the real cost and the necessity. However, sometimes a simple reset of the on-board computer can solve many "electronic problems", a feature available in the "CarDiag" application.

* Have an OBD-II compatible car : OBD-II is compatible with all US vehicle models since 1996, European since 2001 (diesel since 2003), Japanize since 2006.
