Freightliner Business Class M2 Fuse Box Diagram

The main fuse box, also known as the power distribution module, or PDM, is located under the hood onthe left front fender just forward of the bulkhead module.
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 relays are needed. The multiplexing module performs the functions normally provided by relays.

The trailer fuse box and the taillight fuse box, on vehicles 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.
