2020 Honda CR-V: Fuse Box Diagram & Amperage

Quick answer

The 2020 Honda CR-V has two primary fuse box locations:

1. Under-Hood Fuse Box: Located in the engine bay on the driver's side, near the battery.
2. Interior Fuse Box: Located inside the cabin, under the dashboard on the driver's side, near the kick panel.

Under-Hood Fuse Box

This fuse box contains fuses and relays for high-current components like the engine control module (ECM), cooling fans, starter motor, and ABS. To access it, open the hood and locate the black plastic box on the driver's side. Press the tabs on the lid to remove it. You'll find a diagram printed on the underside of the lid.

Note: Fuse configurations can vary based on your CR-V's trim level (LX, EX, EX-L, Touring) and options. Always cross-reference with the diagram on your fuse box lid.

Under-Hood Fuses & Relays

Relays in this box often include:

• Starter Motor Relay
• A/C Clutch Relay
• Fuel Pump Relay
• Blower Motor Relay
• Cooling Fan Relay

Interior Fuse Box

This fuse box handles most of the cabin electronics, including the radio, power outlets, interior lights, and instrument panel. It's located under the driver's side dashboard, high up against the firewall. Access can be tight, so a flashlight is recommended.

How to test a fuse

If a component suddenly stops working, a blown fuse is a likely culprit. Here's how to check:

1. Turn Off the Vehicle: Turn the ignition off and remove the key.
2. Locate the Fuse: Find the correct fuse for the faulty component using the tables above or your owner's manual.
3. Remove the Fuse: Most fuse boxes have a small plastic "fuse puller" tool clipped inside. Use it to gently pull the suspect fuse straight out of its slot.
4. Visual Inspection: Hold the fuse up to the light. Inside the plastic body, you should see a small metal strip. If this strip is intact and continuous, the fuse is good. If the strip is broken or looks burnt, the fuse is blown and needs to be replaced.
5. Replace the Fuse: Always replace a blown fuse with a new one of the exact same amperage rating. Using a higher-rated fuse can cause a fire. The amp rating is printed on top of the fuse.

Common blown fuses on this vehicle

A blown fuse is a symptom, not the root cause. The fuse blew to protect the circuit from excessive current.

• Fuse #1 or #2 (Power Outlets - 20A Yellow): This is the most common blown fuse. It's almost always caused by a faulty phone charger, a coin falling into the outlet, or a defective device plugged into the port. What to check first: Unplug all devices from your 12V outlets. Inspect the outlets for any foreign objects. Replace the fuse and test the outlet with a known-good charger.

• Fuse #24 (Audio / Infotainment System - 15A Blue): If your radio or touchscreen suddenly goes black, this fuse is a good place to start. Sometimes these fuses blow for no apparent reason, but it can also be a sign of a fault in the audio unit itself. What to check first: Try a simple reset by replacing the fuse. If it blows again immediately, there may be a short in the wiring or an internal fault in the radio head unit.

• Fuses #17 & #18 (Low Beam Headlights - 10A Red): If a single headlight goes out, the bulb is the most likely cause. However, if you replace the bulb and it still doesn't work, check the fuse for that specific side. If both headlights go out at once, it's more likely a relay or the headlight switch, but checking the fuses is a quick and easy first step. What to check first: Visually inspect the headlight bulbs. If a bulb looks good, check the corresponding fuse.

Remember to verify fuse locations with the diagram printed on your fuse box lid, as variations can exist. For complex electrical issues, it's always best to seek professional help.
