Fuse box <em>Nissan Murano Z51</em>: diagram, location and replacement

Nissan Murano Z51 (2015–2021) is a crossover that combines comfort and technology, but even in such a reliable car, problems with electrical equipment periodically arise. Most often, the culprit is burnt out fuses or faulty relay. If your headlights don't work, the audio system fails, or the windows stop opening, the first thing you should do is check the fuse box.

In this article you will find precise diagrams of fuses and relays for Murano Z51, learn how to correctly diagnose and replace them, and also get answers to frequently asked questions from owners. We'll sort it out unique features of this generation's electrical circuitry, which are not described in standard manuals.

Where is the fuse box located in Nissan Murano Z51

B Murano Z51 provided two main fuse boxes:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. To access it, just open the driver's door and unlatch the cover latches.
• ⚡ Additional block under the hood — located next to the battery, in a plastic box with the inscription FUSE & RELAY BOX. High power fuses are located here (for example, for the ignition system or cooling fan).

Also in Murano Z51 There is third mini-block — it is hidden behind the glove compartment and is responsible for the multimedia system and climate control. Access to it is difficult, so it is worth checking it only in case of targeted malfunctions (for example, if the screen or air conditioner does not work).

Important! Before working with the block under the hood, be sure to remove the negative terminal from the batteryto avoid short circuit. Once inside, just turn off the ignition and remove the key.

Diagram and decoding of the cabin unit fuses

Salon block Murano Z51 contains fuses for most comfort and safety systems. Below is a table with a breakdown the most popular fuses (numbers may vary slightly depending on the year of manufacture and configuration).

Fuse no.	Denomination (A)	Purpose	Symptoms of a problem
F1	10A	Engine Management System (ECM)	Floating speed, error P0600
F10	15A	Audio system, navigation	Screen doesn't work, no sound
F15	20A	Window lifters (all 4 doors)	Windows do not open/close
F22	10A	Parking sensors (parking sensors)	Rear/front sensors do not work
F30	25A	Heated seats	The seats do not heat, the indicator blinks

The complete diagram can be found in instruction manual (section 8-30), but there is often no data available on fuses for optional systems (e.g. Bose or Around View Monitor). If your Murano equipped with such options, look for additional units behind the glove compartment or under the center console.

⚠️ Attention! fuse F15 (20A) is responsible for all windows. If only one blows, the problem may be with the specific door's motor or wiring, rather than the fuse.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse in the light - the blown thread will be broken. You can also use the “replacement method”: temporarily install a known-good fuse with the same rating from another slot (for example, from the cigarette lighter).

Decoding the relay in the block under the hood

Block under the hood Murano Z51 contains high power relays and fuses, responsible for critical systems: ignition, fans, fuel pump. Below is the list key relay with their purpose:

• 🔥 R1 — Fuel pump relay. If it fails, the engine will not start or will stall after a few seconds.
• 💨 R3 — Cooling fan relay. If there is a malfunction, the engine overheats, especially in traffic jams.
• 🔋 R5 — Starter relay. A characteristic sign of a breakdown is a clicking sound when you turn the key, but the engine does not turn over.
• 💡 R7 — Low/high beam relay. If one headlight stops working, the problem may be in the lamp or wiring, but if both fail, check the relay.

Feature Murano Z51: relay R3 (cooling fan) often burns out due to moisture entering the unit. If you notice that the fan is unstable, inspect the connectors for oxidation.

To test the relay you can use permutation method: Swap the suspect relay with a known good one (e.g. horn relay R9). If the problem disappears, the relay is faulty.

How to check and replace a fuse: step-by-step instructions

Replacing the fuse in Murano Z51 - a simple procedure, but there are nuances that will help you avoid mistakes:

1. Turn off the ignition and make sure that all electrical appliances (headlights, radio) are turned off.
2. Find the faulty fuse according to the diagram (see section above) or visually (burnt thread, melted body).
3. Remove the fuse with special tweezers from the block (usually it is attached to the block cover). Do not use metal tools - they can damage the contacts.
4. Install a new fuse same denomination. Using a fuse with a large amperage may cause a fire in the wiring!

Important point: If the new fuse blows immediately, do not replace it again - this indicates short circuit in the chain. In this case, you need to diagnose the wiring or device that is connected to this fuse.

⚠️ Attention! B Murano Z51 fuse F25 (10A) is responsible for immobilizer. If it burns out, the car will not start and the key indicator on the dashboard will light up. Do not confuse this malfunction with problems with the chip in the key!

💡

If the fuse blows repeatedly, check the circuit for a short circuit using a multimeter in continuity mode. Disconnect all consumers connected to this fuse and check the resistance between the positive wire and ground. If it is close to zero, there is a short circuit in the circuit.

Frequent problems with fuses in Murano Z51 and their solutions

Owners Murano Z51 often encounter typical faults related to fuses. Here are the most common cases and how to resolve them:

• 🔌 The cigarette lighter fuse has blown (F12, 20A) — usually the connected device is to blame (for example, a faulty DVR or compressor). Disconnect all gadgets and check the circuit.
• 🚗 Turn signals don't work (F5, 10A) - in addition to the fuse, check turn relay (it clicks when turned on) and the lamps in the headlights.
• 🎵 Audio system fails Bose (F10, 15A And F11, 10A) - if the fuses are intact, reset the radio settings (press and hold the button POWER for 10 seconds).
• 🔦 Dimensions do not light up (F8, 10A) - check also light switch on the steering column, it often oxidizes.

Unique problem Murano Z51: In cars produced in 2016–2017, the fuse sometimes blows F18 (7.5A)responsible for rear view camera. This is due to a factory defect in the wiring running through the trunk. The solution is to lay an additional wire with a 5A fuse parallel to the standard one.

If you encounter atypical malfunction (for example, several systems stopped working at the same time), check main fuse in the block under the hood (F100, 100A). Its failure can paralyze half of the car's electronics.

💡

If the problem persists after replacing the fuse, check the relay in the same circuit, as well as the integrity of the wiring. Often, oxidation of contacts in connectors simulates a fuse failure.

How to Extend Fuse Life: Expert Advice

Fuses in Murano Z51 are not eternal, but their resource can be significantly increased by following simple recommendations:

• 🔌 Don't overload the circuits — do not connect devices with a total power of more than 120 W to the cigarette lighter (for example, a compressor and a laptop charger at the same time).
• 💧 Protect blocks from moisture — in rainy weather, check the seals of the block covers, especially under the hood. Moisture causes corrosion of contacts.
• 🔧 Clean your contacts regularly - once a year, remove fuses and relays, clean the seats from oxidation (you can use WD-40 or alcohol).
• 🔋 Keep an eye on your battery — low voltage in the on-board network (less than 11.8 V) can cause false tripping of fuses.

If you often drive off-road, install additional protection on the unit under the hood - for example, a silicone case or a plastic casing. This will protect the contacts from dirt and moisture.

Preventive advice: check once every six months fuses for critical systems (fuel pump, ECM, starter) even if there are no signs of malfunction. This will help avoid sudden breakdowns on the road.

FAQ: Frequently asked questions about fuses Nissan Murano Z51

Is it possible to replace a fuse with a higher rating if it keeps blowing?

No! Installing a fuse with a large amperage may lead to wiring fire. If the fuse blows repeatedly, look for the cause - usually it is short circuit or a faulty consumer (for example, a window lift motor).

Where to buy fuses for Murano Z51?

Standard fuses will fit type ATO/ATC (flat, knife). You can buy them:

• In auto stores (Autodoc, Exist, Lada Image)
• In online stores (Wildberries, Ozon, AliExpress — search for "ATC fuses")
• At dealerships Nissan (original, but more expensive)

For relays it is better to take original ones (Nissan 25230-4M000 for the fuel pump) or proven analogues (Bosch, Hella).

Which fuse controls the heated steering wheel? Murano Z51?

The heated steering wheel is controlled by a fuse F28 (10A) in the salon block. If it is working, but the heating does not work, check:

• Power button on the steering wheel (often sticks)
• Connector under the steering wheel (may oxidize)
• Relay R6 in the block under the hood (responsible for comfort circuits)

What should I do if, after replacing the fuse, all devices stop working?

Most likely you installed a fuse wrong denomination or they connected it incorrectly (for example, the polarity in the block under the hood was reversed). Also possible main fuse fault (F100, 100A). Check:

1. The rating of the installed fuse (must match the original).
2. Continuity of the main fuse under the hood.
3. Presence of voltage at the contacts of the unit (with a multimeter).

If the problem persists, contact an auto electrician; it may have burned out. body control module (BCM).

Is it possible to repair fuses (soldering, twisting)?

Absolutely not! The fuse is disposable protective device, designed to operate when the current is exceeded. Any “repair” (twisting, soldering) violates its characteristics and can lead to:

• Overheating of wiring
• Fire
• Failure of expensive modules (for example, ECM or BCM)

If you don't have a replacement on hand, temporarily use a fuse from a less critical circuit (such as the cigarette lighter), but only same denomination!
