How to test a fuse
A blown fuse can be identified in two ways. The first is a visual inspection. Remove the suspect fuse and hold it up to the light. Inside the plastic housing is a small metal strip. If this strip is broken, the fuse is blown. If you can't see the strip clearly, you can also use a multimeter or a 12V test light. With a multimeter, set it to continuity or ohms. Touch the probes to each of the fuse's metal tabs. A good fuse will show continuity or a very low resistance reading. An open circuit or infinite resistance indicates a blown fuse. With a test light, connect the ground clip to a known good ground point on the vehicle's chassis. Probe both metal tabs on the top of the fuse. A good fuse will have power on both sides. A blown fuse will only have power on one side.
Common blown fuses on this vehicle
-
Power Outlet Fuses (Under-Dashboard Fuses #1 & #2): These are some of the most common fuses to blow. The most frequent cause is a faulty phone charger or other device plugged into the power outlet. Before replacing the fuse, unplug any devices and inspect the outlet for foreign debris.
-
Headlight Fuses (Under-Hood Fuses #7 & #8): If a headlight goes out, the fuse is a good first check. If the fuse is blown, it could be a sign that the headlight bulb is about to fail completely. Replace the fuse and the bulb at the same time for best results.
-
Infotainment/Radio Fuse (Under-Dashboard Fuse #5): If your radio or infotainment screen suddenly goes black, this fuse is the likely culprit. This can sometimes be caused by a software glitch. Try replacing the fuse first. If the problem persists, you may need a software update from your Subaru dealer.
Please note that fuse layouts can vary slightly based on your vehicle's trim level and options. Always confirm the fuse locations and ratings with the diagram printed on the inside of your fuse box cover.

Before you pull a fuse on the 2020 Subaru Outback
- 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.
- Disconnect the battery before working near high-current fuses or cables.
