Pull the lock [A] and open the lid [B].
•
Pull out the DFI fuse [C] from the case with needle nose
pliers.

If a fuse fails during operation, inspect the DFI system to
determine the cause, and then replace it with a new fuse
of proper amperage.
DFI Fuse Inspection
•
Remove the fuse (see DFI Fuse Removal).
•
Inspect the fuse element.
If it is open, replace the fuse. Before replacing a blown
fuse, always check the amperage in the affected circuit.
If the amperage is equal to or greater than the fuse rat-
ing, check the wiring and related components for a short
circuit.

CAUTION
When replacing a fuse, be sure the new fuse
matches the specified fuse rating for that circuit.
Do not use a fuse rated for other than amperage
and voltage specified in the Wiring Diagram.
