Hello, i have a stilo 1.2 2002. The airbag lamp is light. Fiat ecuscan error code is: 3C Front crash sensor - Interference detected / Faulty signal ( Intermittent ). I change sensor with new one and nothing );. i buy another airbag ecu with working car and nothing... any ideas?

PS. Sorry for my english );
 
This is a higher class fault. After changing a crash sensor, the fault must be erased with the Examiner or other software. I used FES when I changed the side impact sensor some years ago. The fault will not erase itself, even after eternal startups.

Error code: 3C - Front crash sensor - The reason for this fault is open circuit / short circuit at +V batt
