2014 Nissan Titan Fuse Box Diagram & Amperage Guide

Quick Answer

The 2014 Nissan Titan features three primary fuse box locations: under the hood, behind the driver's side kick panel, and in the cargo area/trunk.

Under-Hood Fuse Box (IPDM E/R)

This fuse box, also known as the Intelligent Power Distribution Module Engine Room (IPDM E/R), is located in the engine compartment, typically near the vehicle battery on the driver's side. It houses high-amperage fuses and relays for major systems.

Common Relays in this box include: Fuel Pump Relay, Starter Relay, Headlight Relays, Blower Motor Relay, and ABS Relays. Always refer to the diagram on the inside of your fuse box lid for exact relay identification, as configurations can vary slightly.

Cabin Fuse Box (Behind Driver's Side Kick Panel)

This fuse box is located inside the cabin, typically behind a removable panel on the driver's side, near the kick panel by your left foot. It protects various interior electrical components.

Cargo Area / Trunk Fuse Box

For the 2014 Nissan Titan, particularly models equipped with a Tow Package or certain premium features, an auxiliary fuse box may be located in the cargo area or under the rear bench seat. This box often handles power for trailer wiring, rear power outlets, or other accessories. Due to trim variations, the best practice is always to consult your owner's manual and the diagram on the fuse box cover.

How to Test a Fuse

1. Locate the fuse box: Refer to the "Quick Answer" section and the diagrams above to find the correct fuse box for the circuit you're troubleshooting.
2. Identify the suspected fuse: Use the tables and your vehicle's fuse box lid diagram to find the fuse associated with the problematic component.
3. Visual inspection: Many modern fuses have a visible wire element. If the wire is broken or melted, the fuse is blown and needs replacement.
4. Use a fuse tester or multimeter: For a more precise test, remove the fuse and use a fuse tester or set a multimeter to the continuity setting. Touch the probes to the metal contact points on the fuse. A good fuse will show continuity (a beep or a reading of zero ohms). A blown fuse will show no continuity.
5. Always replace with the correct amperage: Never substitute a fuse with one of a higher or lower amperage rating. This can cause damage to the electrical system or even a fire. The color of the fuse typically indicates its amperage (e.g., red for 10A, blue for 15A).

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more prone than others due to the nature of the components they protect. For the 2014 Nissan Titan, common culprits include:

• Cigarette Lighter / 12V Outlets (15A/20A): These often blow due to overloads from charging multiple devices or using high-power accessories. If yours isn't working, check the corresponding fuse in the cabin fuse box first.
• Headlight Fuses (10A/15A): If one or both of your headlights suddenly stop working, check the respective fuses in the under-hood fuse box. While less common, a short in the wiring or a failing bulb can sometimes cause these to blow.
• Brake Light Fuse (15A): If your brake lights aren't illuminating, this fuse in the under-hood box is a prime suspect. Before replacing, ensure your brake light switch isn't stuck.
• Trailer Brake Control / Towing Fuses (various): If your trailer lights or brakes aren't functioning, inspect the trailer-related fuses in both the under-hood and potentially the cargo area fuse boxes. Often, a short in the trailer's wiring or an overloaded accessory can cause these to blow.
• Radio / Infotainment Fuse (10A): If your stereo suddenly goes silent or won't power on, a blown fuse in the cabin fuse box is a very common cause.

Always remember to check the simplest solutions first. Before diving into complex diagnostics, verify that the fuse is indeed blown and that the component itself is not faulty.
