2019 Honda Odyssey Fuse Box Diagram & Amperage

Quick Answer

The 2019 Honda Odyssey features three main fuse box locations: under the hood, behind the driver's side kick panel, and in the cargo area on the driver's side.

Under-Hood Fuse Box

The under-hood fuse box is located on the driver's side of the engine compartment, near the battery. It contains fuses and relays for critical engine components, headlights, and other high-current circuits. Always consult the lid of your specific Odyssey's fuse box for the most accurate diagram, as trim levels can have slight variations.

Relay Locations (Under-Hood):

• Fuel Pump Relay: Typically located near the fuel pump fuse.
• Starter Relay: Often found near the starter fuse.
• Main Relay: Powers various main electrical systems, typically larger than individual circuit relays.
• Headlight Relays: Separate relays for high and low beams, left and right sides.
• Cooling Fan Relays: Two relays for the main and sub cooling fans.
• A/C Clutch Relay: Controls the air conditioning compressor clutch.

Driver's Side Dash Fuse Box

This fuse box is located behind the driver's side kick panel, accessible by removing the cover. It typically houses fuses for interior accessories, power windows, and various control modules. Again, verify the legend on the cover for your specific vehicle.

Cargo Area Fuse Box

The cargo area fuse box is located on the driver's side, behind an access panel. This box often protects rear-specific components, such as power outlets, the rear entertainment system, and in some trims, the trailer brake controller.

*Note: The trailer brake controller fuse is typically for an aftermarket accessory. Vehicles with factory-installed towing packages might have dedicated circuits in the under-hood box.

How to Test a Fuse

Testing a fuse is a straightforward process and can save you a trip to the mechanic. Here's how:

1. Locate the Fuse Box: Identify the fuse box relevant to the component that's not working.
2. Identify the Suspect Fuse: Consult the fuse box diagram (either on the lid or in your owner's manual) to find the fuse for the non-functional component.
3. Remove the Fuse: Use the plastic fuse puller usually found in the fuse box lid or a pair of needle-nose pliers to carefully remove the suspect fuse. Gently pull it straight out.
4. Visually Inspect: Hold the fuse up to a light. A good fuse will have a continuous wire or metal strip inside. If the wire is broken, charred, or melted, the fuse is blown and needs to be replaced.
5. Use a Multimeter (for a more thorough test):
   • Set your multimeter to the continuity or ohms setting.
   • Touch the probes of the multimeter to the two metal prongs on top of the fuse (or the metal ends if it's a blade fuse). A good fuse will show a reading close to zero ohms (indicating continuity) or beep if your multimeter has an audible continuity test. A blown fuse will show an "OL" (open loop) or infinite resistance, and no beep.
6. Replace with the Correct 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 the nature of the circuits they protect or typical usage. If you're experiencing an electrical issue, start by checking these fuses:

• Cigar Lighter / 12V Outlets: These fuses (15A blue in the dash and cargo boxes) often blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or air compressor isn't working, check these first.
• Radio / Infotainment System: The 10A red fuse in the dash box protecting your radio can blow if there's a short circuit in the system or an aftermarket component was incorrectly installed. If your radio, navigation, or backup camera display is blank, this is a good place to start.
• Power Windows: The 15A blue fuses in the dash box for your power windows can blow if a window motor is straining or there's a short in the wiring. If a single window isn't working, check its specific fuse.
• Brake Lights: The 7.5A brown fuse in the dash box for the brake lights is crucial for safety. If your brake lights aren't illuminating when you press the pedal, this fuse is a prime suspect. Also check the brake light switch itself.
• Blower Motor: The 40A green fuse in the under-hood box protects your HVAC blower motor. If your heat or AC fan isn't working on any setting, this high-amperage fuse is a common culprit. A failing blower motor can draw too much current and cause this fuse to blow.

Remember to always verify the printed legend in the fuse box lid for the most accurate information regarding your specific 2019 Honda Odyssey trim level.
