2024 Freightliner Cascadia Power Distribution

In the 2024 Freightliner Cascadia, there are primarily two fuse boxes:

  1. Battery Cable Access Box (BCA):
    • The BCA box serves as the primary interface for transferring battery power from outside the cab to the inside.
    • It is located on the passenger side of the engine compartment front wall.
    • On vehicles with optional high current receptacles or inverters, the BCA box includes circuit protection and power cables for those devices.
    • Fuse locations are specified on a label on the BCA cover.
  2. Vehicle Power Distribution Module (VPDM):
    • The VPDM acts as a fuse and relay power distribution box, providing power and circuit protection for powertrain needs, cab functions, and various standalone modules.
    • It also supplies power to emergency power supply circuits in case of module failure.
    • The VPDM is situated in the vehicle electronics bay, behind the passenger-side dash panel.

These fuse boxes play critical roles in managing power distribution and circuit protection throughout the Freightliner Cascadia.
