Introduction If fuses burn out WARNING Replacement fuses and circuit breakers must always be the same rating as the original equipment shown. Never replace a fuse or circuit breaker with one of a higher rating. Higher rated fuses or circuit breakers could allow circuit overloading in the event of a circuit malfunction, resulting in severe vehicle damage or personal injury due to fire. Burned-out or blown fuses usually indicate an electrical short-circuit, although a fuse may occasionally burn out from vibration. Insert a second fuse. If this fuse immediately burns out and you cannot locate the cause, return your vehicle to your dealer for a circuit check. Refer to the Owner 's Manual for replacement of fuses. Selective catalytic reduction system speed limit and Idle-only modes If the vehicle's speed is limited or in an idle-only mode, the selective catalytic reduction system may be limiting the vehicle's functions due to low or contaminated DEF. Check the DEF. See Selective Catalytic Reduction System (page 21). 7 Super Duty (TFA) , enUSA

Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check.
Refer to the Owner’s Manual for
replacement of fuses.
