The 2017 Freightliner M2 106 typically has fuse boxes located in the following areas:
- Under the hood: On the driver's side, often integrated with the power distribution center.
- Inside the cab (Dash/Kick-panel): Behind a panel on the passenger side kick panel or lower dash area.
Always verify the exact location and fuse/relay assignments by checking the fuse box legend printed on the inside of the fuse box cover, as configurations can vary based on specific vehicle options and trim levels.
<h2>Under-Hood Fuse Box (Power Distribution Center)</h2>The under-hood fuse box, often part of the Power Distribution Center (PDC), contains fuses and relays for critical systems such as the engine control module (ECM), fuel pump, ignition, starter, ABS, and high-current accessories. Refer to the lid for exact fuse numbers and descriptions.

Before you pull a fuse on the 2017 Freightliner M2 106
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Many heavy trucks have more than one power distribution point (cab, under-hood or near the batteries), and some circuits use circuit breakers instead of fuses. Some systems have 24-volt starting circuits; confirm the voltage before testing.
- Disconnect the battery before working near high-current fuses or cables.
