General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Totally Integrated Power Module
The Totally Integrated Power Module is lo-
cated in the engine compartment near the
battery. This center contains cartridge fuses,
mini fuses, and relays. A label that identifies
each component is printed on the inside of
the cover.
