2009 F150 Fuse Box Diagram: Exploring the Fuse Boxes

2009 F150 Fuse Box Diagram: Find the correct fuse for the circuit you’re working on

The 2009 F150 fuse box diagram and the entire fuse setup for the 2009 F150 are completely different from the preceding years. In 2009, Ford began using two fuse boxes: an under-hood fuse box called the Battery Junction Box/Power Distribution Box and a passenger compartment fuse box called the Smart Junction Box/Passenger Compartment Fuse Panel. The passenger compartment Smart Junction Box is a precursor to what we now call a Body Control Module (BCM). In previous model years, Ford used a rudimentary BCM called a Generic Electronics Module (GEM). The GEM module controlled all the lights, door sensors, windshield wipers, and keyless entry.

In 2009, the GEM module got a new name

Starting in 2009, Ford changed the name of the GEM module to the Smart Junction Box and began mounting fuses for the controlled devices into it. In later years, Ford finally changed the name to the BCM.

The 2009 F150’s passenger compartment fuse box is under the instrument panel’s passenger side. The under-hood fuse box is called the Power Distribution Box or the Battery Junction Box (BJB). It is a rectangular box mounted in the center of the vehicle, under the hood, and above the radiator.

Find the most commonly replaced fuses and bulbs here

The fuse box diagram and table below show all 71 fuses and all the relays. But most DIYers are looking for fuses and relays for the lights, power ports, and the blower motor.  I’ve listed the most commonly checked/replaced fuses here to save time. I’ve also listed the most commonly replaced bulbs. A blown fuse or bulb are the two most common reasons for lighting issues

Backup Light: Fuse #39 (BJB) 10A, Bulb #3156 flareside, #921 styleside
Blower Motor: Fuse #51 30A (BJB)
Headlight Low Beam Passenger Side: Fuse #8 10A (SJB), Bulb #H13 (dual filament for high and low beams)
Headlight Low Beam Driver’s Side: Fuse #7 10A (SJB), Bulb #H13 (dual filament for high and low beams)

2009 F150 Fuse Box Diagram for Battery Junction Box/Power Distribution Box

The power distribution box/ battery junction box is located in the engine compartment, in the center, and above the radiator. The junction box houses the high-current fuses and relays that protect and operate your vehicle’s main electrical systems.

How to find your fuse and the devices served by that fuse

There are 82 fuse slots and relay slots in the underhood power distribution box. The chart shows only 10 to speed up load time. Here’s how to find the fuse and circuit you want.
1) Change the number of entries showing (in the Show Entries Box) to 100 and scroll the list.
2) Enter the name of the component you’re searching for in the Search box.
3) Use the Next/Previous buttons at the bottom of the table

A note about fuses, battery power and keep alive memory

If you disconnect the battery or remove the PCM fuses from the fuse box, the PCM will lose its adaptive memory and baseline throttle body position. You can avoid this by providing backup power using a jumper pack and an inexpensive OBDII cable. See this article for more information on providing backup power to prevent the loss of adaptive memory. Or, you can perform a throttle body relearn procedure and then drive the vehicle so it can relearn the new adaptive memory settings. See this article for instructions on how to perform a 2009 F150 throttle body relearn procedure.

2009 F150 Fuse Box Layout for Smart Junction Box

This fuse box is referred to by several names: Smart Junction Box, Body Control Module, and Passenger Compartment Fuse Panel. The passenger compartment fuse panel is under the instrument panel’s right-hand side, behind a trim panel. To remove the trim panel for access to the fuse box, pull the panel toward you, swing it out away from the side, and remove it. To reinstall it, line up the tabs with the grooves on the panel, then push it shut.

Tips to diagnose electrical issues on your 2009 F150

If your power windows don’t work
• The power windows don’t use fuses. They get power from a 30A circuit breaker #47 in the smart junction box.

If your blower motor doesn’t work
The blower motor gets its power from the blower motor relay #3 in the battery junction/power distribution box.

If the circuit you’re working on contains a relay
• A simple way to test a relay is to swap in a similarly shaped relay and see if the component works.
• If that doesn’t work, remove the relay and test for power to the relay control coil and contacts using a multimeter. For more information on relay testing, see this article.
