2023 Honda CR-V — Fuse Box Diagram & Amperage

Quick Answer

The 2023 Honda CR-V features multiple fuse box locations to protect its electrical systems: one under the hood, one in the driver's side dashboard kick panel, and another in the cargo area/trunk.

Under-hood Fuse Box

The under-hood fuse box is located in the engine compartment, typically near the battery. It houses fuses and relays for critical engine functions, headlights, and other high-current components. Always consult the diagram on the fuse box lid for the most accurate information as configurations can vary slightly by trim level.

Relay Locations (Under-hood):

The under-hood fuse box also contains several relays. Common relays found here include:

• Fuel Pump Relay: Controls power to the fuel pump.
• Starter Relay: Engages the starter motor when the ignition is turned.
• A/C Compressor Clutch Relay: Activates the A/C compressor clutch.
• Headlight Relays: Controls power to the high and low beam headlights.
• Cooling Fan Relays: Manages the engine cooling fans.

Driver's Side Dashboard Kick Panel Fuse Box

This fuse box is typically located behind a panel on the driver's side, near the kick panel or under the steering column. It protects various interior electrical components, accessories, and some control modules. Always refer to the sticker on the back of the panel or the owner's manual for the exact fuse layout for your specific trim.

Cargo Area/Trunk Fuse Box

Some 2023 Honda CR-V models may feature an additional fuse box in the cargo area or trunk. This fuse box typically handles power for rear accessories, such as the rear power outlet, trailer wiring, or certain rear-mounted electronic modules. Check your owner's manual or the panels in the cargo area for its exact location and fuse assignments.

How to Test a Fuse

Fuses are designed to be the weakest link in an electrical circuit, protecting more expensive components from damage due to overcurrent. If an electrical component stops working, checking the relevant fuse is often the first step in diagnosing the issue.

1. Locate the Fuse Box: Identify the fuse box corresponding to the non-functioning component using the diagrams above or your owner's manual.
2. Identify the Suspect Fuse: Using the tables, find the fuse number and circuit description for the component that isn't working.
3. Remove the Fuse: Use the plastic fuse puller usually found in the fuse box lid (or needle-nose pliers) to carefully extract the suspect fuse. Always ensure the ignition is off before removing fuses.
4. Inspect the Fuse: Visually inspect the fuse. A good fuse will have a continuous wire filament inside. If the filament is broken or burned, the fuse is blown. For opaque fuses, you'll need a multimeter.
5. Test with a Multimeter (Optional but Recommended): Set your multimeter to the continuity or ohms setting. Touch one probe to each metal blade of the fuse. A good fuse will show a reading close to zero ohms or continuity (the multimeter will beep). A blown fuse will show no reading or open circuit.
6. Replace the Fuse: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and type. Using a fuse with a higher amperage can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more common than others due to frequent use or transient electrical spikes. If you experience an issue, consider checking these first:

• Cigar Lighter/12V Power Outlets: These fuses often blow due to short circuits from faulty accessories or overloading the outlet.
• Radio/Infotainment System: Issues with aftermarket installations or electrical glitches can sometimes cause this fuse to blow.
• Blower Motor: A failing blower motor or obstructions can cause it to draw excessive current, blowing its fuse.
• Headlights: While less common with modern systems, a persistent headlamp outage might warrant checking its specific fuse.
• Trailer Brake Controller (if equipped): Faulty trailer wiring or an overloaded trailer electrical system can cause this fuse to blow.

Always remember to check the associated component after replacing a blown fuse. If the new fuse blows immediately, there's likely a short circuit or a faulty component that needs professional attention.
