Locating Your 2002 Honda Accord Fuse Boxes
Your 2002 Honda Accord, like most modern vehicles, doesn’t just have one fuse box; it typically has two main locations. Each box controls different sets of electrical circuits, and knowing where to find them is the first step in any electrical diagnosis.
Under-Hood Fuse/Relay Box
This is often the primary power distribution hub, housing fuses and relays for high-current components like your headlights, cooling fan, anti-lock brake system (ABS), and engine control unit (ECU). You’ll typically find this box on the driver’s side of the engine bay, near the battery.
- Location: Open the hood and look towards the driver’s side fender, often tucked away behind the battery or near the strut tower.
- Access: It’s usually a black plastic box with a snap-on or clip-on lid. You might need to press a tab or unclip a few latches to open it.
- Identification: The inside of the lid often contains a mini 2002 Honda Accord fuse box diagram printed directly on it, showing the fuse layout and their corresponding circuits.
Interior Fuse Box (Under-Dash)
This box handles fuses for your cabin electronics and accessories. Think radio, power windows, dashboard lights, turn signals, and the cigarette lighter/power outlets. These are generally lower-amperage circuits.
- Location: In your 2002 Honda Accord, the interior fuse box is most commonly found under the driver’s side dashboard. You might need to get on your hands and knees and look up towards the firewall.
- Access: It’s often hidden behind a small plastic cover that can be pried off with a flat-head screwdriver or your fingers. Sometimes, it’s just exposed.
- Identification: Similar to the under-hood box, there’s usually a sticker or embossed diagram on the cover or nearby panel that serves as your interior 2002 Honda Accord fuse box diagram.
Always ensure your vehicle is turned off and the key is out of the ignition before you start poking around in any fuse box. Safety first, always!
Understanding the 2002 Honda Accord Fuse Box Diagram
Once you’ve located the fuse boxes, the real work begins: interpreting the diagrams. The 2002 Honda Accord fuse box diagram can look like a foreign language at first, but with a few pointers, you’ll be reading it like a pro. This is how to effectively use your 2002 Honda Accord fuse box diagram to pinpoint issues.
Deciphering the Symbols and Amperage
Each diagram uses symbols and numbers to represent circuits and fuse ratings. Here’s what to look for:
- Symbols: These are usually small icons representing the component the fuse protects. For example, a headlight symbol, a radio symbol, or a cigarette lighter icon. If symbols aren’t present, there will be abbreviations.
- Abbreviations: Common abbreviations include “HEAD” for headlights, “ACC” for accessories, “RADIO,” “WIPER,” “ABS,” “ECU,” etc.
- Amperage (Amps): This is the most crucial number, indicating the maximum current the fuse can handle. It’s always printed on the fuse itself and listed in the diagram. Fuses come in various colors, which correspond to their amperage rating (e.g., 10A is red, 15A is blue, 20A is yellow).
Never replace a fuse with one of a higher amperage rating. This is a critical safety rule. Doing so can lead to overheating wires, electrical fires, and severe damage to your vehicle’s electrical system.
Types of Fuses You’ll Encounter
Your Accord uses several types of fuses, but the most common are:
- Blade Fuses: These are the most common, small plastic fuses with two metal prongs that plug into the fuse box. They come in mini, standard, and maxi sizes.
- Cartridge Fuses: Larger, typically found in the under-hood box for high-current circuits.
- Relays: While not fuses, relays are often housed in the same box and are crucial for switching higher current circuits (e.g., starter, fuel pump). They look like small black or grey plastic cubes.
Your diagram will clearly show which slot corresponds to which circuit and what amperage fuse it requires. Take a picture of the diagram with your phone for easy reference when you’re at the auto parts store.
Troubleshooting Common Electrical Issues with Your Fuse Box
Now that you know where the fuse boxes are and how to read the diagram, let’s tackle some common problems with 2002 Honda Accord fuse box diagram interpretation and electrical diagnosis. This systematic approach is key to effective troubleshooting.
When an electrical component stops working, follow these steps:
- Identify the Affected Component: Is it the radio, headlights, power windows, or something else?
- Consult the Fuse Box Diagram: Locate the fuse (or fuses) corresponding to that specific component using your 2002 Honda Accord fuse box diagram. Remember to check both the under-hood and interior diagrams.
- Locate the Fuse in the Box: Match the position on the diagram to the physical fuse in the box.
- Visually Inspect the Fuse: Carefully pull the suspect fuse straight out using a plastic fuse puller (usually found clipped inside the fuse box lid or purchased cheaply). Hold it up to the light.
- A good fuse will have an intact metal wire or strip connecting the two prongs.
- A blown fuse will have a broken, burnt, or melted wire/strip inside.
- A good fuse will show continuity (a beep or a reading close to zero ohms).
- A blown fuse will show no continuity (no beep or an “OL” reading).
If you find a blown fuse, you’ve likely found your problem! If the fuse is good, the issue lies elsewhere, perhaps with the component itself, the wiring, or a relay.
What if a New Fuse Blows Immediately?
This is a critical sign of a deeper issue. If you replace a blown fuse and the new one blows instantly, it indicates a short circuit in the wiring or the component it powers. Do not keep replacing fuses; this can cause further damage or even a fire. At this point, it’s often best to consult a professional mechanic or automotive electrician.

Frequently Asked Questions About Your 2002 Honda Accord Fuse Box Diagram
Where can I find a complete 2002 Honda Accord fuse box diagram?
The most accurate diagrams are usually printed on the inside of the fuse box covers themselves (both under-hood and interior). If yours is missing or illegible, check your owner’s manual. Many online forums and dedicated Honda Accord enthusiast sites also have digital copies, or you can often find them on a service manual website like Honda-Tech or similar resources.
Why do my fuses keep blowing even after I replace them?
If a new fuse blows immediately, it’s almost certainly due to a short circuit in the wiring or the component it powers. This means the electrical current is finding an unintended path, drawing too much amperage, and blowing the fuse to protect the circuit. Continuing to replace fuses without addressing the short can cause serious damage or fire. Seek professional diagnosis.
Can I use a higher amperage fuse temporarily?
Absolutely not. This is extremely dangerous and can lead to overheating wires, melting components, and potentially an electrical fire. Fuses are designed to be the weakest link in a circuit, protecting the more expensive and critical components. Always replace a blown fuse with one of the *exact same amperage rating*.
What’s the difference between a fuse and a relay?
A fuse is a safety device designed to break a circuit if too much current flows through it, protecting components from damage. A relay is an electromagnetic switch that uses a small current to control a larger current. For example, a small current from your ignition switch might activate a relay, which then allows a much larger current to flow to your starter motor or fuel pump.
What if my owner’s manual doesn’t have a clear fuse diagram?
While uncommon, if your physical owner’s manual is lacking, check Honda’s official website for a digital copy of the manual for your specific year and model. Alternatively, many reputable online automotive repair resources and forums dedicated to the 6th generation Honda Accord (1998-2002) can provide detailed diagrams and community support.
