Field-Effect Transistor (FET) Protection

Field-Effect Transistor (FET) protection is used to protect the BCM  output drivers from damage in the event that an excessive current draw is detected on a BCM  output. Each illumination circuit connected to the BCM  is separately protected. Refer to the SYSTEM DIAGRAM  in this service information to view the different groups of BCM  non-networked illumination outputs. For a full description of Field-Effect Transistor (FET) protection,
