Two main fuse boxes exist on the 2015 Civic: one under the hood in the engine compartment and another inside the cabin on the driver's side. Each box has a cover with a diagram showing fuse numbers and what they protect.
Engine compartment fuse box
The engine compartment fuse box is located on the driver’s side of the engine bay. It sits near the left front area of the engine compartment, close to the strut tower and away from the battery in most configurations.
Before you inspect or replace fuses, familiarize yourself with how to access this box and read its labeling. The following list explains the steps and what to expect.
- Open the hood and locate a black plastic fuse/relay box on the driver’s side of the engine bay. The lid is usually labeled “FUSE BOX” or “FUSES.”
- Remove the lid by lifting the tabs or clips; some lids have a pull-tab for easy removal. A fuse puller is often stored inside the box.
- Inside the lid, you’ll find a diagram listing fuse numbers and their respective circuits (e.g., ECU, ABS, headlights, etc.).
- Check or replace fuses with the same amperage rating as indicated on the diagram. If a fuse is blown, replace it and test the corresponding system.
- After replacement, re-seat the lid securely to protect the fuses from moisture and debris.
In brief, the engine compartment fuse box is under the hood on the driver’s side and is the primary location for most engine and powertrain-related circuits.
Interior fuse box
The interior fuse box is located inside the vehicle on the driver’s side, typically in the lower dash area near the knee and ankle region. Access may require removing a small trim panel or cover on the left side of the driver’s footwell.
Before you work with interior fuses, read the instructions and diagrams that accompany this box. The list below outlines how to locate and use this box.
- Look under the driver’s side dash or knee area and locate the interior fuse box cover. It may be tucked behind a small panel or trim piece.
- Remove the cover to reveal the fuse layout and amperage ratings printed on the underside or inside the lid.
- Use the fuse puller stored in the box (or a small needle-nose plier) to remove a blown fuse. Check the fuse for a broken metal strip inside.
- Replace with a fuse of the same amperage rating and reseat it firmly. Do not exceed the specified rating for safety.
- Close the cover and reattach any trim panels you removed.
In summary, the interior fuse box sits on the driver’s side inside the cabin and governs many interior and accessory circuits, such as lights, radios, and HVAC controls.
What to know before you start
Consult the owner’s manual for the exact fuse ratings and a precise mapping of each fuse to its function, as there can be slight variations by trim level or regional market. If a fuse repeatedly blows, there may be an underlying electrical fault that should be examined by a technician.
Safety tips
Always turn off the ignition and remove the key (or disconnect the battery if advised by the manual) before inspecting fuses. Use the correct amperage rating when replacing fuses, and avoid using substitutes like coins or jumpers to bypass a fuse.
Summary
The 2015 Honda Civic houses two fuse boxes: an engine compartment box under the hood on the driver’s side and an interior box inside the cabin on the driver’s side near the knee area. Each box has a labeled diagram to guide you to the right fuse, and a fuse puller is typically included in the box. Always match the replacement fuse to the listed amperage and refer to the owner’s manual for specifics related to your exact trim.
