2015 Honda Odyssey: Fuse Box Diagram & Amperage

Quick answer

On the 2015 Honda Odyssey, you will find three primary fuse box locations:

• Under-Hood Fuse Box: Located in the engine bay on the driver's side, near the battery.
• Driver's Side Interior Fuse Box: Located under the dashboard on the driver's side, near the kick panel.
• Passenger's Side Interior Fuse Box: Located behind the glove box.

Always verify fuse locations and ratings with the diagram printed on your vehicle's fuse box cover(s) before replacing any fuses.

Under-Hood Fuse Box

This fuse box contains larger, high-amperage fuses and relays that protect the most critical vehicle systems. To access it, release the clips on the black plastic cover.

Relay Locations (Under-Hood)

• R1: Starter Relay
• R2: PGM-FI Main Relay (Fuel Pump)
• R3: A/C Compressor Clutch Relay
• R4: Blower Motor Relay
• R5: Horn Relay

Driver's Side Interior Fuse Box

This fuse panel is located beneath the dashboard on the driver's side. It handles a wide range of interior circuits.

Passenger's Side Interior Fuse Box

To access this fuse box, you must first open and empty the glove box, then press in on the sides to release the retaining tabs and let it swing completely down and out of the way.

How to test a fuse

A fuse is a simple safety device. If a circuit overloads, a thin wire inside the fuse melts and breaks the connection, protecting expensive components from damage.

1. Turn the vehicle off.
2. Locate and remove the suspect fuse. A small fuse puller tool is often included in the fuse box lid.
3. Visually inspect the fuse. Look at the thin metal strip inside the plastic body. If it is broken or melted, the fuse is blown.
4. Use a multimeter (for certainty). Set your multimeter to the continuity setting (it often looks like a sound wave symbol). Touch the probes to the two metal prongs on the top of the fuse. If the multimeter beeps or reads close to zero ohms, the fuse is good. If it remains silent or reads "OL" (Over Limit), the fuse is blown.
5. Replace with the same amperage. Always replace a blown fuse with a new one of the exact same amperage rating. Using a higher-rated fuse can cause a fire.

Common blown fuses on this vehicle

• Front Accessory Power Socket (15A): This is the most common fuse to blow. It is often caused by a faulty phone charger, a coin falling into the socket, or a defective accessory. Before replacing the fuse, unplug whatever was in the socket and inspect the socket for foreign objects.
• Audio System / Radio (20A): If your radio and infotainment screen suddenly go dead, this fuse is the first place to look. It can blow from age or an internal fault in the radio unit itself.
• Blower Motor (40A): If your cabin climate fan stops working on all speeds, check this high-amperage fuse. If the fuse is blown, it can be a sign that the blower motor itself is wearing out and drawing too much current, or that the blower motor resistor has failed.
• PGM-FI Main / Fuel Pump (15A): If this fuse blows, the engine will crank but will not start because the fuel pump is not getting power. This is a critical fuse. A failure can be due to a short in the wiring or a failing fuel pump that is beginning to seize up and draw excess current.

If a fuse blows repeatedly, it indicates an underlying short or a component that is drawing too much power. Do not simply keep replacing fuses; have the circuit professionally diagnosed.
