As the hood goes over center, the damper auto-
matically slows its rate of descent. If needed, you
can also slow its rate of descent with your hand.
3. Make sure the hood is flush with the cowl, then
secure the hood by engaging both hood hold-
down latches.
IMPORTANT: Make sure that both hold-down
latches are fully engaged before operating the

Fuse Identification

Main Fuse Box/PDM

The main fuse box, also known as the power distri-
bution module, or PDM, is located under the hood on
the left front fender just forward of the bulkhead mod-
ule. See Fig. 2.11. To open the fuse box, pull down
on the wire clips holding the lid on the fuse box.
A sticker inside the lid of the fuse box shows the lo-
cations of the fuses and describes the circuit(s) that
each fuse protects (see
descriptions of a typical set of fuses. The fuses in the
main fuse box are mini blade-type fuses. Battery
power fuses, located near the batteries, are bolt-in
megafuses.
Because the electrical system is multiplexed, no re-
lays are needed. The multiplexing module performs
the functions normally provided by relays.

Trailer and Taillight Fuse Boxes

The trailer fuse box and the taillight fuse box, on ve-
hicles so equipped, are mounted on a bracket with
the chassis module on the left-hand frame rail aft of
the cab, or on a crossmember at the end of the
frame rail. These may be referred to as the chassis
fuse box or chassis PDM. See
