Vehicle Power Distribution

The vehicle power distribution system provides bat-
tery power to the electrical and electronic systems.
The following components make up the vehicle
power distribution system:
Battery Cable Access (BCA)
Vehicle Power Distribution Module (VPDM)
Optional Cab Load Disconnect Switch (CLDS)
Vehicle power is supplied by the batteries to the bat-
tery cable access (BCA) box. The BCA front wall
pass-through is the primary interface through which
battery power gets transferred from outside the cab

to the inside. It is located on the passenger side of
the engine compartment front wall. See
On vehicles equipped with an optional high current
receptacle and/or optional inverter, the BCA will have
circuit protection and power cables supplying those
devices. Fuse locations will depend on the vehicle
and will be outlined on a label on the BCA cover. For
an example see
Fig. 11.6.
The power supplied by the batteries goes to the ve-
hicle power distribution module (VPDM) and the
single signal detect and actuation (sSAM) module.
The VPDM is a fuse and relay power distribution
box. It provides power and circuit protection for pow-
ertrain needs, cab functions, and various stand alone
modules. It also supplies power to the emergency
