Nissan Nv200 Fuse Box Diagram

The Nissan NV200, a versatile compact cargo van, relies on a network of fuses to protect its electrical circuits. Understanding the fuse box diagram is crucial for troubleshooting electrical issues, replacing blown fuses, and even tapping into power for aftermarket accessories. This article will provide a comprehensive guide to the NV200's fuse boxes, covering their locations, layouts, and functions.

Fuse Box Locations

The NV200 typically has two primary fuse box locations:

Interior Fuse Box: Located inside the cabin, usually under the dashboard on the driver's side. You may need to remove a small access panel to reveal it. This box primarily houses fuses for interior components such as the radio, lights, power windows, and other convenience features.
Engine Compartment Fuse Box: Situated within the engine bay, often near the battery or the air filter housing. This box protects critical engine management systems, headlights, and other components vital for vehicle operation.

The exact location might vary slightly depending on the model year and trim level, so always consult your owner's manual for the most accurate information. Safety first! Before working on any electrical system, disconnect the negative terminal of the battery to prevent accidental shorts or electrical shock.

Understanding Fuse Box Diagrams

Each fuse box has a corresponding diagram that identifies the function of each fuse. This diagram is usually located on the inside of the fuse box cover. If it's missing, you can often find it in your owner's manual or online. The diagram will show a schematic representation of the fuse box, with each fuse labeled with a number and a description of the circuit it protects.

Interpreting the Diagram

Here's a breakdown of the common elements you'll find on a fuse box diagram:

Fuse Number/Identifier: Each fuse is assigned a unique number or identifier (e.g., "Fuse 1," "F1," "IGN1"). This number corresponds to a specific location in the fuse box.
Circuit Description: This provides a brief description of the component or system the fuse protects (e.g., "Radio," "Headlights," "Power Windows," "ABS").
Amperage Rating: This indicates the maximum current (measured in Amperes, or Amps) that the fuse can safely handle before it blows. Fuses come in different amperage ratings (e.g., 5A, 10A, 15A, 20A, 30A).
Fuse Type: Most NV200s use blade-type fuses, which are color-coded according to their amperage rating. The color coding helps you quickly identify the correct replacement fuse.

Important: Always replace a blown fuse with one of the same amperage rating. Using a fuse with a higher amperage can overload the circuit and potentially cause damage to wiring or components, or even start a fire. Using a lower amperage fuse may cause it to blow prematurely.

Common Fuse Functions and Examples

While the exact layout and fuse assignments may vary, here are some common fuse functions you'll likely find in the NV200's fuse boxes:

Interior Fuse Box

Radio/Audio System: Protects the power supply to the radio, CD player, and other audio components.
Interior Lights: Covers the dome light, map lights, and other interior illumination.
Power Windows/Locks: Protects the circuits for the power windows and door locks.
Cigarette Lighter/Accessory Power Outlet: Supplies power to the cigarette lighter socket or accessory power outlet.
Instrument Cluster: Protects the power supply to the instrument panel gauges and displays.
HVAC System: Protects the blower motor and other components of the heating and air conditioning system.
Wipers: Provides power to front and rear windshield wipers.

Engine Compartment Fuse Box

Headlights: Protects the circuits for the low beams, high beams, and daytime running lights.
Taillights/Brake Lights: Covers the rear taillights, brake lights, and turn signals.
Fuel Pump: Protects the fuel pump, which delivers fuel to the engine.
Engine Control Unit (ECU): Provides power to the ECU, the brain of the engine management system.
Anti-Lock Braking System (ABS): Protects the ABS module, which controls the anti-lock braking function.
Starter Motor: Protects the starter motor circuit.
Ignition System: Provides power to the ignition coils and other components of the ignition system.
Cooling Fan: Protects the radiator cooling fan motor.

These are just a few examples, and the specific functions and amperage ratings may vary depending on the NV200's equipment and model year. Always refer to your vehicle's fuse box diagram for accurate information.

Troubleshooting Blown Fuses

If an electrical component in your NV200 stops working, the first thing to check is the corresponding fuse. Here's a step-by-step guide to troubleshooting blown fuses:

Identify the Affected Component: Determine which component is not working.
Locate the Correct Fuse: Consult the fuse box diagram to identify the fuse that protects the affected component.
Inspect the Fuse: Carefully remove the fuse from the fuse box. You can use a fuse puller tool (usually included in the fuse box) or a pair of needle-nose pliers. Examine the fuse closely. A blown fuse will typically have a broken or melted filament.
Test the Fuse (Optional): For a more accurate diagnosis, you can use a multimeter to test the fuse for continuity. Set the multimeter to the continuity setting (usually indicated by a diode symbol or a sound wave symbol). Touch the probes to the two terminals of the fuse. If the multimeter shows continuity (usually indicated by a beep or a reading of 0 ohms), the fuse is good. If the multimeter shows no continuity (usually indicated by an open circuit or a very high resistance reading), the fuse is blown.
Replace the Fuse: Replace the blown fuse with a new fuse of the same amperage rating. Do not use a higher amperage fuse.
Test the Component: After replacing the fuse, test the affected component to see if it is working properly.
If the Fuse Blows Again: If the new fuse blows immediately or shortly after being replaced, there is likely a short circuit or other electrical problem in the circuit. Further diagnosis by a qualified mechanic is recommended. Do not keep replacing the fuse without addressing the underlying problem.

Modifying and Adding Circuits

Some DIYers may want to tap into the NV200's electrical system to add aftermarket accessories such as auxiliary lights, a dashcam, or a power inverter. While this is possible, it's crucial to do it safely and correctly to avoid damaging the vehicle's electrical system. Here are some guidelines:

Use a Fuse Tap: A fuse tap (also known as an Add-a-Circuit) allows you to safely tap into an existing fuse slot without cutting or splicing wires. It plugs into the existing fuse slot and provides a new fuse slot for the aftermarket accessory.
Choose the Correct Fuse Slot: Select a fuse slot that is appropriate for the accessory you are adding. Consider the amperage rating of the accessory and choose a fuse slot that can handle the load. An ignition-switched fuse is usually preferred for accessories you only want to operate when the vehicle is running.
Proper Wiring and Connections: Use high-quality wiring and connectors that are properly sized for the current draw of the accessory. Ensure that all connections are secure and insulated to prevent shorts.
Grounding: A good ground connection is essential for proper operation and safety. Connect the accessory's ground wire to a clean, bare metal surface on the vehicle's chassis.
Consult a Professional: If you are not comfortable working with electrical wiring, it's best to consult a qualified mechanic or automotive electrician.

Disclaimer: Modifying your vehicle's electrical system can void your warranty and may have unintended consequences if not done correctly. Proceed with caution and at your own risk.

Conclusion

Understanding the Nissan NV200's fuse box diagram is an essential skill for any owner. It allows you to troubleshoot electrical issues, replace blown fuses, and even add aftermarket accessories safely. By following the guidelines outlined in this article, you can confidently maintain and modify your NV200's electrical system. Remember to always consult your owner's manual for the most accurate and up-to-date information.
