The Honda BRV fuse box diagram is more than just a technical drawing—it is your first line of defense against electrical headaches. By knowing the locations (engine bay and behind the driver’s side dash panel) and understanding how to read the labels, you can diagnose and fix 80% of minor electrical faults in under ten minutes.

Always keep a variety of blade fuses in your glove box (available for a few dollars at any auto parts store) and your owner’s manual handy. The next time your BRV’s power window or radio fails, you can confidently pop the fuse box, read the diagram, swap the fuse, and get back on the road.

Disclaimer: This guide is for informational purposes. While accurate for most Honda BRV models (2016–present), fuse assignments can change between manufacturing plants and model years. Always consult your vehicle’s owner’s manual as the primary source.

The Honda BR-V is a popular compact SUV known for its reliability and practicality. However, like any vehicle, it's not immune to electrical issues. Understanding the fuse box diagram can help you troubleshoot and resolve electrical problems efficiently.

Location of the Fuse Box

The fuse box in the Honda BR-V is located under the dashboard on the driver's side. It's also known as the "Integrated Control Unit" or "ICU". You can access it by pulling down the fuse box cover.

Relay Box

The Honda BR-V also has a relay box located near the fuse box. The relay box contains the following relays:

Tips and Precautions

Finding the fuse box in your Honda BR-V is straightforward once you know where to look. Most models feature two or three primary locations that house the electrical protectors for your vehicle’s components. Primary Fuse Box Locations

Engine Compartment (Under-Hood): This primary box is located at the back side of the engine compartment on the left side, often near the battery. To access it, simply push the tabs to release the cover.

Interior (Under-Dashboard): The interior fuse box is typically found underneath the dashboard on the driver’s lower left side. It may be located near the steering column and sometimes requires turning a knob to open the panel.

Secondary Under-Hood Box: Some configurations include a secondary box located next to the main battery. Engine Compartment Diagram Highlights

For many petrol models, the engine fuse box protects critical systems. Common fuse ratings include:

Headlights: Main low beam (20 A), with individual right and left low beams at 10 A each. Hazard Lights: 10 A. Wiper System: 30 A. Horn: 10 A.

Ignition & Starter: IG Coil (15 A), Starter SW (30 A), and Starter (7.5 A). Essential Maintenance Tips

Check the Lid First: Always refer to the diagram printed on the inside of the fuse box cover before pulling any fuses. This is the most accurate source for your specific trim.

Use the Proper Rating: Never replace a blown fuse with one of a higher amperage. This significantly increases the risk of damaging your car's electrical system or causing a fire. If you don't have the exact match, use a lower rating temporarily.

The "Finicky Trick": When reading diagrams, orient yourself by matching the series of amp ratings (e.g., a row of 5-15-10-15) on the physical fuses to the same sequence shown on the visual diagram.

For complex wiring tasks like hardwiring a dashcam, enthusiasts often use the S-HTR or ACC fuse slots for power. For more detailed circuit lists, you can view the Honda BRV Fuse Diagrams on Scribd.

Tools needed: Fuse puller (usually inside the under-hood fuse box) or needle-nose pliers.

Steps:

  • Push in a new fuse of the exact same amperage rating.
  • Close the cover and test the component.
