2022 Nissan Frontier Fuse Box Diagram & Amperage

Quick answer

The 2022 Nissan Frontier has three primary fuse box locations:

• Under-hood fuse box (IPDM E/R): Located in the engine bay, on the passenger side, near the battery.
• In-cabin fuse box: Located inside the cab, under the driver’s side of the dashboard.
• Battery-mounted fuse block: A smaller set of fuses directly attached to the positive battery terminal.

Under-hood Fuse Box (IPDM E/R) Location & Diagram

This main fuse box, which Nissan calls the Intelligent Power Distribution Module Engine Room (IPDM E/R), is located in the engine compartment on the passenger side. It houses the high-amperage fuses and relays that control most of the primary vehicle systems. You will need to remove the black plastic cover to access them.

Always verify the fuse layout with the diagram printed on the underside of your fuse box cover, as variations can exist based on your vehicle's specific trim and options.

Main Fuse Block

Relays

• R1: Starter Relay
• R2: Fuel Pump Relay
• R3: ECM/PCM Main Relay
• R4: A/C Clutch Relay
• R6: Blower Motor Relay
• R7: Fog Lamp Relay

In-Cabin Fuse Box Location & Diagram

This fuse box is located inside the truck, behind a small panel on the lower part of the dashboard to the left of the steering column. It contains the smaller fuses for interior components and various electronic modules.

Battery-Mounted Fuse Block

Attached directly to the positive terminal clamp of your battery is a small, high-amperage fuse block. These are fusible links that protect the most critical and high-draw systems on the truck.

How to Test a Fuse

A blown fuse can be identified in two ways:

1. Visual Inspection: Carefully pull the fuse from its slot using a fuse puller (often found in the fuse box cover). Hold it up to the light. Inside the plastic body is a thin metal strip. If that strip is broken or melted, the fuse is blown.
2. Multimeter Test: For a more definitive test, set a multimeter to the continuity setting (often looks like a sound wave symbol). Touch the two metal prongs of the fuse with the multimeter probes. If the multimeter beeps, the fuse is good. If it remains silent, the fuse is blown and has no continuity.

When replacing a fuse, always use a new fuse with the exact same amperage rating. Using a higher-rated fuse can cause severe damage to the electrical system and create a fire hazard.

Common Blown Fuses on the 2022 Nissan Frontier

• 12V Power Outlet (Cigar Lighter) Fuse: This is one of the most common fuses to blow. It is often caused by a faulty phone charger, a loose coin falling into the outlet, or an accessory that draws too much power. If the 15A "Power Outlet" fuse is blown, check the outlet for debris before replacing the fuse.
• Fuel Pump Fuse: If your Frontier cranks but won't start, the fuel pump fuse is a good first place to check. A blown fuse could indicate a problem with the fuel pump relay or the pump itself. Listen for a faint humming or buzzing sound from the gas tank area when you first turn the key to the "on" position; if it's silent, the fuel pump isn't running.
• Trailer Light Fuses: When towing, faulty trailer wiring is a frequent cause of blown fuses for tail lights or turn signals. If you notice a light on your truck goes out only when a trailer is connected, the issue is likely with the trailer's wiring, not the truck's.

If a fuse blows a second time immediately after you replace it, you have an underlying short circuit in that system that needs to be diagnosed and repaired.
