2022 Nissan Titan Fuse Box Diagram & Amperage Guide

As an ASE-certified master technician, I've spent plenty of time diagnosing electrical gremlins and tracing circuits. When your 2022 Nissan Titan suddenly loses power to the radio, the trailer lights stop working, or the fuel pump won't prime, the very first place you should check is the fuse box.

Modern trucks like the Titan have complex electrical systems, but checking and replacing a fuse is still one of the easiest maintenance tasks you can do. This guide breaks down the fuse box locations, diagrams, and amperage ratings for the 2022 Nissan Titan.

Disclaimer: Fuse configurations can vary slightly depending on your Titan's trim level (S, SV, PRO-4X, Platinum Reserve) and options (like the tow package or premium audio). Always verify against the printed legend on the inside of your fuse box lid before replacing a fuse.

Quick answer

On the 2022 Nissan Titan, the fuses and relays are split between two primary locations:

1. Passenger Compartment Fuse Box: Located inside the cabin, on the driver's side lower dashboard / kick panel area. You will need to pull off the plastic cover to access it.
2. Engine Compartment Fuse Box (IPDM E/R): Located under the hood on the passenger side near the battery. Nissan calls this the Intelligent Power Distribution Module Engine Room. There is also a secondary fuse block attached to the positive battery terminal containing high-amp fusible links.

Passenger Compartment Fuse Box

The interior fuse box handles most of your cabin electronics, including the infotainment system, climate control switches, 12V outlets, and safety restraints.

Relays for the accessory power and ignition are typically built into the BCM or located above the main fuse block inside the dash.

Engine Compartment Fuse Box (IPDM E/R)

The Intelligent Power Distribution Module (IPDM) under the hood manages the heavy-duty circuits. This includes engine management, exterior lighting, towing circuits, and the ABS system.

Note: The primary starter relay, cooling fan relays, and A/C clutch relays are integrated into the IPDM E/R circuit board on modern Nissans.

How to test a fuse

As a master tech, I always tell my apprentices: don't just rely on your eyes. A fuse can look perfectly fine but still be blown (a hairline fracture in the element). Here is the proper way to test a fuse:

1. Use a Multimeter or Test Light: Turn the ignition switch to the "ON" position (do not start the engine).
2. Probe the Test Points: Look at the top of the fuse. You will see two tiny exposed metal tabs.
3. Test Light Method: Clip the ground wire to a good bare metal chassis ground. Touch the probe to one tab, then the other. If the test light illuminates on both tabs, the fuse is good. If it lights up on only one side, the fuse is blown. If it doesn't light up on either side, that circuit isn't currently receiving power (switch might be off).
4. Multimeter Method: Set your meter to measure DC voltage. Touch the black probe to ground, and the red probe to each test tab on the fuse. Both sides should read roughly 12 volts. Alternatively, pull the fuse and test for continuity (Ohms) across the two blades.

Always replace a blown fuse with one of the exact same amperage rating and type (typically Low-Profile Mini or Micro2 fuses for the Titan). Never use a higher amp fuse to "solve" a blown fuse problem; you risk melting the wiring harness or starting a fire.

Common blown fuses on this vehicle

If you're dealing with electrical issues on a 2022 Nissan Titan, check these common culprits first:

• Trailer Fuses (Fuses 32, 33, 34): The Titan is a workhorse, which means it tows. Bad wiring on an old trailer is the number one cause of blown trailer light or brake controller fuses. If your trailer lights stop working, check the IPDM under the hood before assuming the truck's wiring is bad.
• 12V Power Outlets (Fuses 4 & 10): Dropping a coin into the center console cigar lighter/12V socket or plugging in a faulty phone charger will instantly pop the 20-amp interior fuses.
• Fuel Pump (Fuse 21): While not incredibly common on a nearly-new 2022 model, if the truck cranks robustly but refuses to start, always verify the 15A fuel pump fuse in the engine bay.
• A/C Compressor Clutch (Fuse 22): If your blower motor is pushing warm air but the refrigerant levels are fine, verify the A/C clutch fuse hasn't blown due to an electrical surge or failing clutch coil.

If you keep blowing the same fuse repeatedly, you have a short to ground in that circuit or a failed component drawing too much current. Stop replacing the fuse and have the circuit properly diagnosed.
