2014 Ford Fusion Se Fuse Box Diagram

Okay, let's dive into the fuse box diagram for the 2014 Ford Fusion SE. This isn't just a pretty picture; it's your roadmap to understanding and troubleshooting your car's electrical system. Whether you're dealing with a blown fuse, installing aftermarket accessories, or just trying to learn more about your vehicle, this diagram is an invaluable resource. We’ve got the complete diagram available for download – more on that later.

Why You Need This Diagram

Think of your car's electrical system as a complex network of roads. Fuses are the traffic lights and stop signs, preventing electrical surges from causing major damage. The fuse box diagram is the map of that network. You'll need it for:

• Troubleshooting Electrical Issues: Identifying the correct fuse for a malfunctioning component (e.g., radio, headlights, power windows) is the first step in diagnosing the problem.
• Installing Aftermarket Accessories: Properly tapping into the electrical system for accessories like aftermarket lights, stereos, or dash cams requires knowing which circuits are safe to use and their amperage ratings.
• General Car Maintenance: Understanding the fuse layout helps you maintain your vehicle and prevent potential problems before they escalate.
• Learning about your car's electrical system: Even if you’re not doing a specific repair, understanding the electrical layout will make you a more confident car owner.

Key Specs and Main Parts

The 2014 Ford Fusion SE has two main fuse boxes:

• Battery Junction Box (BJB): Located in the engine compartment, typically near the battery. This box houses fuses and relays for high-current components like the starter motor, alternator, and cooling fan. It’s also sometimes referred to as the Power Distribution Box (PDB).
• Smart Junction Box (SJB): Located inside the passenger compartment, usually behind a kick panel or under the dashboard. This box controls lower-current circuits like interior lights, power windows, and the radio.

Key Specifications:

• Voltage: The Fusion operates on a 12-volt DC electrical system. This is the standard for most modern cars.
• Amperage Ratings: Fuses are rated in amps (A). The rating indicates the maximum current the fuse can handle before blowing. Replacing a fuse with one of a higher amperage is extremely dangerous and can lead to electrical fires. Always use the correct amperage.
• Fuse Types: The 2014 Fusion SE uses various fuse types, including blade fuses (ATO/ATC), mini blade fuses, and cartridge fuses. The diagram will specify which type is used for each circuit.

Understanding the Symbols on the Diagram

Fuse box diagrams aren't always the easiest to read, but once you understand the basic symbols, they become much clearer.

Lines and Colors

• Solid Lines: Represent direct electrical connections between components.
• Dotted Lines: Indicate connections through a wiring harness or a component that isn't directly part of the fuse box. They might also indicate a shared ground.
• Colors: Wiring colors are often indicated on the diagram with abbreviations (e.g., RD for red, BLK for black, YEL for yellow). These colors correspond to the actual wires in your car.

Icons and Abbreviations

• Fuse Symbol: Typically a rectangle with a wavy line running through it.
• Relay Symbol: Usually a square or rectangle with internal markings representing the coil and switch contacts. A relay is an electrically operated switch that allows a low-current circuit to control a high-current circuit.
• Component Abbreviations: Common abbreviations include:
  • PCM: Powertrain Control Module (engine computer)
  • BCM: Body Control Module
  • ABS: Anti-lock Braking System
  • SRS: Supplemental Restraint System (airbags)
  • GEM: Generic Electronic Module

Important: The fuse diagram will have a legend or key that explains all the symbols and abbreviations used. Refer to this legend for clarification.

How It Works: A Simplified Explanation

Let’s say your radio suddenly stops working. Here's how you'd use the fuse box diagram:

1. Consult the Diagram: Locate the SJB fuse box diagram. The diagrams are typically found in the owner's manual or on a sticker inside the fuse box cover.
2. Identify the Radio Fuse: Look for the fuse labeled "Radio" or "Audio System." The diagram will show the fuse number and amperage rating.
3. Locate the Fuse in the Fuse Box: Open the SJB and find the fuse corresponding to the number identified in the diagram.
4. Inspect the Fuse: Visually inspect the fuse. If the thin wire inside the fuse is broken, the fuse is blown and needs to be replaced.
5. Replace the Fuse: Replace the blown fuse with a new fuse of the exact same amperage rating.

If the radio still doesn't work after replacing the fuse, the problem may be more complex, such as a wiring issue or a faulty radio unit.

Real-World Use: Basic Troubleshooting Tips

Here are some common troubleshooting scenarios and how to use the fuse box diagram to solve them:

• Blown Fuse Keeps Reappearing: If a fuse blows repeatedly, there's likely a short circuit or an overload in the circuit. Don't just keep replacing the fuse. You need to find and fix the underlying problem. This might involve checking the wiring for damage or replacing a faulty component.
• Incorrect Fuse Installed: Using the wrong amperage fuse can cause problems. A fuse with too low amperage will blow prematurely, while a fuse with too high amperage may not protect the circuit and could lead to damage or fire. Always use the correct amperage.
• No Power to Multiple Components: If several components aren't working, check for a common fuse or relay that supplies power to all of them. The diagram can help you identify these shared components.
• Accessory Installation Issues: When installing aftermarket accessories, use the diagram to identify a suitable circuit to tap into. Choose a circuit with sufficient amperage and one that's not critical to the vehicle's operation. Always use a fuse tap or add-a-circuit to protect the original circuit.

Safety Considerations

Working with electrical systems can be dangerous. Keep these safety tips in mind:

• Disconnect the Battery: Before working on any electrical components, disconnect the negative terminal of the battery to prevent accidental shorts or shocks.
• Use Insulated Tools: Use tools with insulated handles to protect yourself from electrical shock.
• Avoid Wet Conditions: Never work on electrical systems in wet or damp conditions.
• Be Careful with High-Current Components: Components like the starter motor, alternator, and airbag system operate at high currents and can be dangerous if not handled properly. If you're not comfortable working with these components, seek professional assistance. The SRS (airbag) system should ONLY be worked on by qualified technicians. Improper handling can cause accidental airbag deployment, resulting in serious injury.
