Main Fuse Box

Freightliner Business Class M2 fuse box diagram: main fuse

The main fuse box, also known as the Power Distribution Module, or PDM, is located under the hood on the left front fender just ahead of the bulkhead module.

The fuses in the main fuse box are paddle type mini fuses. The battery power fuses located next to the batteries are screw-in mega fuses.

Because the electrical system is multiplexed, no relays are needed. The multiplexing module performs the functions that relays normally perform.
