2017 Nissan Murano Fuse Box Diagram

Understanding your vehicle's electrical system is crucial for proper maintenance and troubleshooting. The fuse box diagram, in particular, acts as a roadmap to the complex network of circuits protecting your car's components. This article focuses specifically on the 2017 Nissan Murano's fuse box diagram, providing a detailed guide for intermediate car owners, DIY enthusiasts, and modders. Knowing how to interpret this diagram allows you to diagnose electrical issues, perform basic repairs, and even safely add aftermarket accessories without causing damage.

Purpose of the 2017 Nissan Murano Fuse Box Diagram

The primary purpose of the fuse box diagram is to identify the specific fuse or relay associated with a particular electrical circuit. This is invaluable for several reasons:

Troubleshooting Electrical Problems: When a component fails, the first step is often to check its corresponding fuse. The diagram tells you exactly which fuse to examine, saving you time and preventing unnecessary disassembly.
Performing Repairs: If a fuse is blown, the diagram confirms that you're replacing the correct one with the appropriate amperage rating. Using the wrong fuse can lead to further damage or even a fire.
Adding Aftermarket Accessories: When installing accessories like aftermarket stereos, lights, or remote starters, you'll often need to tap into existing circuits. The diagram helps you identify safe and appropriate points to connect without overloading any circuits.
General Understanding: Studying the diagram provides a deeper understanding of your vehicle's electrical system, empowering you to perform basic maintenance tasks and communicate more effectively with professional mechanics.

Key Specs and Main Parts of the Fuse Box

The 2017 Nissan Murano typically has multiple fuse boxes. The most commonly accessed are located:

Inside the Cabin: Usually located under the dashboard, often on the driver's side. This box generally houses fuses for interior components like the radio, lights, power windows, and climate control.
Under the Hood: Located in the engine compartment, near the battery. This box protects circuits related to engine management, headlights, power steering, and the ABS system.

Each fuse box contains a variety of fuses and relays. Key specs to consider include:

Amperage Rating: Fuses are rated in amps (A), indicating the maximum current they can handle before blowing. The diagram will specify the correct amperage for each fuse. Using a fuse with a higher amperage rating can be dangerous and should never be done.
Fuse Type: Common fuse types include blade fuses (ATO, Mini, Low-Profile Mini), cartridge fuses, and fusible links. The diagram will typically indicate the fuse type, though visually inspecting the fuse is always a good idea.
Relays: Relays are electromechanical switches that allow a low-current circuit to control a high-current circuit. They're often used to control things like headlights, horns, and starter motors. The diagram will show which relay controls which circuit.

Understanding the Symbols and Conventions

Fuse box diagrams use a variety of symbols and conventions to represent electrical components and their connections. Key elements include:

Lines: Solid lines represent wires connecting different components. Thicker lines may indicate heavier gauge wires used for higher current circuits.
Colors: Wire colors are often indicated on the diagram using abbreviations (e.g., BLK for black, RED for red, WHT for white). These colors help you trace wires within the vehicle.
Fuse Symbols: A fuse is typically represented by a jagged line or a rectangle with a wavy line inside. The amperage rating is usually printed next to the symbol.
Relay Symbols: A relay is often represented by a rectangle with a coil symbol inside, along with switch contacts.
Component Symbols: Simplified symbols represent various components like headlights, motors, and control modules. These symbols are usually labeled with abbreviations or descriptive names.

Pay close attention to the legend or key provided with the diagram. This key explains the meaning of each symbol and abbreviation used. Some diagrams also include connector locations and wiring harness routing information.

How It Works: From Diagram to Circuit

The fuse box diagram depicts the electrical circuits as they are laid out in the vehicle. Each circuit originates from the battery, passes through a fuse or relay (for protection and control), and then powers a specific component. Let's imagine a simple example: the circuit for the right headlight.

The diagram shows a line originating from the battery positive (+) terminal.
This line leads to a fuse in the under-hood fuse box, labeled "Headlight (RH)" with a specific amperage rating (e.g., 15A).
From the fuse, the line continues to the headlight switch, allowing the driver to control the headlight.
When the headlight switch is turned on, the circuit is completed, and current flows to the right headlight, causing it to illuminate.
If there's a short circuit in the headlight or its wiring, excessive current will flow, causing the fuse to blow and interrupting the circuit.

By following the lines and symbols on the diagram, you can trace the flow of electricity through each circuit and identify potential points of failure.

Real-World Use: Basic Troubleshooting Tips

Here's how you can use the fuse box diagram to troubleshoot common electrical problems:

Symptom: The radio doesn't turn on.
Action: Consult the fuse box diagram in the cabin fuse box. Locate the fuse labeled "Radio" or "Audio System."
Check: Inspect the fuse visually. If the filament inside the fuse is broken, it's blown. You can also use a multimeter to test the fuse for continuity. A reading of 0 ohms or close to it indicates a good fuse.
Replacement: Replace the blown fuse with a new fuse of the same amperage rating.
If the fuse blows again immediately: This indicates a short circuit in the radio or its wiring. Further investigation is required by a trained mechanic.

Important Note: Always disconnect the negative (-) battery terminal before working on any electrical components. This prevents accidental short circuits and potential injury.

Safety Considerations

Working with automotive electrical systems can be dangerous. Always follow these safety precautions:

Disconnect the Battery: As mentioned, disconnect the negative battery terminal before starting any electrical work.
Never Bypass a Fuse: Bypassing a fuse with a wire or higher amperage fuse can cause a fire.
Don't Work in Wet Conditions: Water conducts electricity and increases the risk of shock.
Be Careful with Airbags: Airbag systems contain capacitors that can store a charge even after the battery is disconnected. Consult a service manual for proper airbag deactivation procedures before working near airbag components.
Identify High-Voltage Circuits: Be especially cautious around components related to the ignition system (coils, spark plugs) and the charging system (alternator). These circuits can carry high voltages.

Certain components, like the ECU (Engine Control Unit) and the ABS (Anti-lock Braking System) module, are particularly sensitive to voltage fluctuations and should only be serviced by qualified technicians.

By understanding the 2017 Nissan Murano fuse box diagram and following proper safety precautions, you can confidently troubleshoot basic electrical issues and maintain your vehicle's electrical system.
