Why does the Ford Fiesta immobilizer light come on?
Years 2008-2017

Answer

The cause of this warning light coming on is very often linked to a defect or breakage of the transponder coil, or to the immobilizer box itself, which despite having received the authentication code correctly, does not allow the engine to be started.
