2018 Honda Pilot – Fuse Box Diagram & Amperage

Quick Answer

The 2018 Honda Pilot has three main fuse box locations: under the hood, under the dashboard (driver's side kick panel), and in the cargo area (right side panel).

Under-Hood Fuse Box

This fuse box is located in the engine compartment on the driver's side, near the battery. It contains fuses for major electrical components and relays. Always refer to the diagram on the fuse box lid for the most accurate information for your specific trim level.

Relay Locations (Under-Hood):

• R1: Starter Relay
• R2: Fuel Pump Relay
• R3: Cooling Fan Relay
• R4: Condenser Fan Relay
• R5: A/C Clutch Relay
• R6: PGM-FI Main Relay
• R7: Headlight HI Relay (RH)
• R8: Headlight LO Relay (RH)
• R9: Headlight HI Relay (LH)
• R10: Headlight LO Relay (LH)

Interior Fuse Box (Driver's Side Dash Kick Panel)

This fuse box is located on the driver's side, behind a cover on the kick panel to the left of the footrest. You may need to remove a plastic trim piece to access it. Again, always check your vehicle's specific fuse legend.

Cargo Area Fuse Box (Right Side Panel)

This fuse box is typically located behind a removable panel on the right side of the cargo area, often near the spare tire access or storage compartment. This location usually handles power for specific rear accessories and power outlets.

How to Test a Fuse

1. Safety First: Turn off the ignition and any affected circuits.
2. Locate the Fuse: Use the fuse box diagram to identify the suspected fuse.
3. Remove the Fuse: Use the fuse puller (usually found in the under-hood fuse box) to carefully remove the fuse.
4. Visual Inspection: Hold the fuse up to the light. If the metal wire inside is broken or discolored, the fuse is blown.
5. Multimeter Test (for less obvious breaks): Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch the probes to the metal contact points on top of the fuse. A good fuse will show continuity (the multimeter will beep or show a reading close to zero ohms). A blown fuse will show no continuity ("OL" or infinity).
6. Replace with Correct Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage and type. Using a fuse with a higher amperage can cause serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more commonly encountered due to their circuits or usage.

• Cigar Lighter / 12V Power Outlets (Interior Fuse Box #7, #8, #24): These fuses often blow due to overcurrent from charging multiple devices or using high-power accessories. If your power outlets aren't working, check these first. Make sure nothing is short-circuited in the outlet itself.
• Brake Lights (Interior Fuse Box #3): A blown brake light fuse will cause your brake lights to stop working, which is a safety hazard. This can be caused by a short in the wiring or a faulty brake light switch. If your cruise control also stops working, it often points to this fuse or the brake switch.
• Headlights (Under-Hood Fuse Box #9, #10, also #22-A, #22-B for LED): If one or both of your headlights suddenly stop working (and the bulbs are confirmed good), check these fuses. Sometimes a bad bulb can cause the fuse to blow.
• Blower Motor (Under-Hood Fuse Box #8): If your cabin fan stops working entirely on all speeds, this large fuse is a primary suspect. Before replacing, ensure there isn't an obstruction in the blower motor itself.
• Radio / Infotainment (Interior Fuse Box #6): If your radio or display stops working, this is a good place to start. Sometimes, installing aftermarket accessories or a direct short within the unit can cause this.

Always remember that a blown fuse is often a symptom, not the root cause. If a fuse repeatedly blows, there's an underlying electrical issue that needs professional diagnosis.
