Nissan Atlas: location of fuses and relays with explanation by year

Owners Nissan Atlas - commercial minibuses, popular in Japan and Asian countries - are often faced with the need to independently diagnose electrical equipment. The fuses and relays in this vehicle are responsible for protecting circuits from overloads, but their location and purpose may vary depending on the year of manufacture and configuration. Unlike European models Nissan, where fuse blocks are standardized, in Atlas the pattern can vary even within one generation.

This article will help you figure out where to look for fuses in Nissan Atlas (including models H25, H26 and restyled versions), how to replace them correctly, and also prevent common mistakes. We have collected current diagrams, transcripts and tips from auto electricians working with Japanese commercial vehicles. Particular attention is paid blocks under the hood and in the cabin, as well as nuances that are not indicated in the standard manual.

Where are the fuse boxes in the Nissan Atlas?

B Nissan Atlas fuses and relays are distributed across three main blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, under the instrument panel. In some versions it is closed with a plastic cover with the inscription FUSE.
• 🚗 Block under the hood - next to the battery, often in a black plastic box with markings FUSE & RELAY BOX.
• ⚡ Additional relay block — may be located behind the glove compartment or under the center console (depending on the year of manufacture).

In models Atlas H25 (2000–2007) the main fuse box is often combined with a relay, while in H26 (2007–2015) relays are placed in a separate module. For exact location check marking on the block cover — the diagram is usually indicated there. If the cover is missing or worn, use a flashlight: fuses in Atlas often marked with colored markers (for example, red - 10A, blue - 15A).

Important: In some export versions (for example, for the Southeast Asian market), blocks may be moved. If you do not find a fuse according to the standard diagram, check service book — alternative locations are sometimes indicated there.

Interpretation of fuses in the cabin block

The interior block is the most accessible for inspection. The table below shows a typical description for Nissan Atlas H26 (2007-2015), but check the label on the top of your unit for denominations!

Fuse no.	Rating (A)	Purpose	Symptoms of a problem
1	10	Interior lighting, instrument lighting	The lamps do not work, the panel lamps are dim
5	15	Cigarette lighter, 12V socket	The cigarette lighter does not work, the radio settings are reset
10	20	Window lifters (all doors)	The windows do not go up/down, a relay click is heard
14	7.5	Engine control unit (ECU)	The engine stalls, the Check Engine lights up, errors P0600–P0606
18	10	Audio system, navigation	The radio does not turn on, the settings are reset

Pay attention to the fuse №14 (7.5A) - he is responsible for nutrition ECU. If it burns out, the engine may stall while driving without being able to restart. In this case, check the circuit for a short circuit, especially if there has been recent work on the wiring or installation of additional equipment (for example, an alarm).

⚠️ Attention: Never replace fuse #14 with a rating higher than 7.5A! This can lead to damage to the engine control unit, the repair cost of which exceeds 50,000 rubles.

Fuse box under the hood: diagram and features

Engine compartment block Nissan Atlas usually contains fuses and relays for power electronics: starter, generator, cooling fans, etc. Its location depends on the engine type:

• 🔋 Gasoline engines (QR20, QR25) — the unit is located to the right of the battery, under the plastic cover.
• ⚡ Diesel engines (YD25, ZD30) — the block is moved closer to the windshield, next to the washer reservoir.

Typical problems with the engine compartment:

• 💦 Corrosion of contacts due to moisture (especially in diesel versions).
• 🔥 Melting of the cooling fan relay connectors (fuse 30A).
• 🔌 Oxidation of starter and generator fuse terminals.

To check the fuses under the hood, use multimeter in dialing mode or visually inspect the filament. If the fuse is blown, do not rush to replace it - first find the cause (for example, a short circuit in the fan circuit).

Disconnect the battery (negative terminal first)|

Clean the block contacts from dirt and oxidation|

Check fuses for integrity (visually or with a multimeter)|

Make sure the relays click when voltage is applied (eg fan relay)|

Relay in Nissan Atlas: purpose and diagnostics

Relay in Nissan Atlas control high current circuits such as the starter, fuel pump, lights and fans. Their failure is often disguised as other faults. For example, if a car does not start, not only the starter may be to blame, but also fuel pump relay or main injection relay.

Relay location:

• 🔑 Starter relay - usually in the engine compartment, marked as STARTER RELAY.
• ⛽ Fuel pump relay — in the cabin unit or under the rear seat (in diesel versions).
• 💡 Low/high beam relay — in the cabin unit, next to the lighting fuses.

To check the relay:

1. Remove the relay from the socket (by gently pulling up).
2. Call contacts 85 And 86 (coil) - the resistance should be 50–120 Ohm.
3. Apply 12V to the contacts 85 And 86 - there should be a click and the contacts 30 And 87 shut up.

If the relay does not click, it must be replaced. For Nissan Atlas Fits standard size relays ISO 280, but it's better to use the original ones Nissan 25230-3M200 or analogues from Panasonic.

⚠️ Attention: In diesel versions Atlas The glow plug relay often fails due to overheating. If the engine has trouble starting when cold, check this relay first - it is located on a bracket next to the fuse box under the hood.

Typical faults and their causes

Owners Nissan Atlas often encounter recurring problems with fuses and relays. Here are the most common cases:

• 🔥 Cigarette lighter fuse blown (15A) - usually caused by connecting powerful devices (for example, a compressor or inverter). Solution: Use a power strip with its own fuse.
• 🚨 Spontaneous shutdown of the radio - the fuse is at fault №18 (10A) or oxidation of contacts in the block. Also check the ground on the body next to the radio.
• 🔋 Power windows don't work - fuse №10 (20A) or a relay in the engine compartment. In the rain it may appear due to moisture getting into the door connectors.
• 💡 Headlights flash or do not light up - check the light relay (HEADLAMP RELAY) and fuses №7 (10A) And №8 (10A).

The problem is especially insidious with ECU fuse (No. 14). If it burns out, the engine may stall while driving, and several errors will light up on the panel at the same time (for example, P0335 And P0605). In this case:

What to do if the ECU fuse is blown?

1. Don't try to replace the fuse right away - first disconnect the battery for 10 minutes.

2. Check the circuit for a short circuit (especially if an alarm or other equipment has recently been installed).

3. Inspect the ECU connector (located under the hood, next to the battery) for oxidation or damage to the wires.

4. If the fuse blows again after replacement, contact an auto electrician - the control unit itself may be damaged.

Another common problem is short circuit in the cooling fan circuit. If the fuse 30A in the engine compartment burns out immediately after replacement, check:

• Condition of the fan connector (often oxidized).
• The integrity of the wiring from the relay to the fan (may rub against the housing).
• The fan itself - if it is jammed, this leads to increased current.

How to properly replace a fuse or relay

Replacing the fuse in Nissan Atlas It seems like a simple procedure, but there are nuances that will help you avoid serious problems:

1. Turn off the power. Always remove the negative terminal from the battery before working on fuses, especially when dealing with circuits ECU or ABS.
2. Use only fuses of the correct rating. For example, if in the nest 10A insert 15A, this may lead to melting of the wiring.
3. Check the cause of the burnout. If a fuse is blown, don't stop at replacing it - look for a short or overload in the circuit.
4. For relays, use original parts. Non-original relays (especially Chinese ones) may not operate due to differences in coil voltage.

To remove fuses in Atlas convenient to use plastic tweezers, which is usually located in the fuse box. If there is none, you can carefully pry the fuse off with a small screwdriver, but do not use excessive force - the plastic latches in the block are fragile.

When replacing the relay, pay attention to contact markings. For example, the fan relay and starter relay are similar in appearance, but have different pinouts. If they are swapped, the fan will run constantly, but the starter will not work.

Where to buy fuses and relays for Nissan Atlas

For Nissan Atlas Both original and similar fuses and relays are suitable. The main thing is to comply with the ratings and sizes.

Part type	Original article	Analogues	Where to buy
Fuses (mini blade)	Nissan 24060-VA000 (set)	Bosch 1987432001, Hella 8ZF 008 136-001	Auto stores, AliExpress, Exist.ru
Relay (ISO 280)	Nissan 25230-3M200	Panasonic VX-40001, Omron G8RN-1A48	eBay, car dismantling yards, electronics stores
Fuse box (cover)	Nissan 28550-4M000	Universal lids from Hella	Japanese car wreckers, Amayama

For rare relays (for example, glow plug relays in diesel versions), it is better to order originals through Amayama or Buyee. An alternative is to search by VIN code on Japanese car wrecker sites.

If you urgently need to replace a fuse, but there is no original one, you can temporarily use a similar one from another socket (for example, a radio fuse instead of a cigarette lighter). However Do not use wire bugs - this may cause a fire!

FAQ: Frequently asked questions about fuses in Nissan Atlas

Can I use higher rated fuses if they keep blowing?

No! Increasing the fuse rating may result in melted wiring or failure of the device it protects. If the fuse blows repeatedly, look for the cause - usually a short circuit or circuit overload (for example, due to additional equipment).

Where is the fuel pump fuse on a diesel Atlas?

In diesel versions Nissan Atlas The fuel pump fuse is usually located in the engine compartment (fuse 15A, marked as FUEL PUMP). The fuel pump relay may be located under the rear seat or in the interior unit.

Why does it blow again after replacing the cigarette lighter fuse?

This is due to the circuit being overloaded. Possible reasons:

• Connecting powerful devices (compressor, inverter).
• There is a short circuit in the outlet or wiring.
• Malfunction of the cigarette lighter itself (short circuit inside the socket).

Solution: Use a power strip with a separate fuse or connect high-power devices directly to the battery through an additional fuse.

How to test the cooling fan relay without a multimeter?

You can temporarily swap it with a known working relay (for example, a horn relay). If the fan starts working after replacement, it means the old relay was faulty. Also when 12V is supplied to the contacts 85 And 86 a click should be heard.

Where can I download the fuse diagram for my version of Atlas?

Official diagrams can be found:

• In the service book (if it is saved).
• On sites with manuals (for example, Nicoclub or CarManualsOnline).
• In owner groups Nissan Atlas on Telegram or Facebook (photos of blocks are often posted there).

If you can't find a diagram, take a photo of your fuse box cover and ask for a transcript on the forums (for example, Drive2).
