2018 Edge Fuse Box Diagram

2018 Edge Fuse Box Diagram: Exploring the Fuse Boxes

The 2012 Edge has three fuse boxes; an underhood fuse box, a passenger compartment fuse box, and a high current fuse box. The passenger compartment fuse box is also called the Body Control Module (BCM). This post shows the 2018 Edge  fuse box diagram for both boxes, and the circuits covered for each fuse

Find the most commonly replaced fuses here

The fuse box diagram and table below show all 62 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.

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 2018 Edge throttle body relearn procedure.

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

There are 87 fuse/relay slots in the Battery Junction 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

Tips to diagnose electrical issues on your 2018 Edge

Headlight operation

Unlike in older models, the multifunction headlight switch does not switch power to the headlights. It is simply a request for headlights. The multifunction switch has a series of resistors that drop voltage as you turn the stalk. The Body Control Module determines whether you’re requesting parking lights, headlights, or high-beam lights based on the voltage drop. The actual power switching of power from the headlight fuse to the headlights is done inside the smart junction box.

If your headlights aren’t working, the easiest way to diagnose the problem is to use a bidirectional scan too to view live data from the smart junction box. You will see that on the scan tool if it’s receiving the headlights ON request. However, if you’ve turned the stalk to headlights and the smart junction box isn’t seeing the request, then the problem is in the multifunction switch or the wiring from the MF switch to the SHB

If your power windows don’t work
• The front power windows are controlled by a door module in each of the front doors. Each door module has its own fuse in the PCFB (Body Control Module). The rear windows are powered by a 30A circuit breaker in the PCFB

If your blower motor doesn’t work
The blower motor gets its power from the blower motor relay #79 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.
