Field-Effect Transistor (FET) Protection
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The Field-Effect Transistor (FET) protection strategy prevents module damage in the event of excessive current flow. For additional information of the FET , refer to MULTIFUNCTION ELECTRONIC MODULES .
The BCM FET protected output circuits for the headlamp system are both low and high beam output circuits.
