Question

I got the codes U0452 and B1676 on my 2012 Ford Fusion SE 3.0L, what could be the problem? Also, my airbag light is on all the time

Answer 1

The B1676 code is related to the ABS system or possibly the alternator, and the U0452 code is related to the Airbag System. I recommend starting by checking the battery charge and the charging system. If the battery is OK, try clearing the codes and see if any of them come back.
