Nissan Murano Z51: complete fuse diagram with decoding and replacement tips

Owners Nissan Murano Z51 (third generation, 2015–2026) sooner or later you have to face the need to check or replace fuses. These small but critical elements protect the vehicle's electrical circuits from overloads and short circuits. However, finding accurate information about the location and purpose of each fuse in the manual is not always easy - especially when we are talking about versions for different markets (USA, Europe, Japan) or restyled models from 2019–2026.

In this article we have collected current fuse block diagrams for Murano Z51, including unique fuse data for hybrid versions (if applicable) and driver assistance systems (ProPILOT). You will learn where the main and additional units are located, how to dismantle them correctly, and also receive practical advice on troubleshooting. We will pay special attention to “problem” fuses that most often fail - for example, those responsible for the multimedia system or heated seats.

Where are the fuse boxes in the Nissan Murano Z51

B Murano Z51 There are two main fuse blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the protective cover. Access to it opens by turning the lock counterclockwise.
• 🚗 Additional block under the hood — located next to the battery (in models with a gasoline engine) or in a special compartment (in hybrid versions). The cover of this unit is usually marked with the symbol "FUSE».

It is important to consider that in cars for North American market (USA/Canada) and European market (EU) not only the fuse ratings may differ, but also their location in the blocks. For example, fuse #32 (15A) in the American version is responsible for NissanConnect, and in European - for Bose Audio System.

Also in some trim levels (for example, with the option Intelligent Around View Monitor) may be present third fuse block — it is located behind the glove compartment and is responsible for driver assistance systems. Few people know about this, but this is what is checked when cameras or parking sensors malfunction.

7	15	Audio system (Bose or standard)	Often burns out when there is a short circuit in the speakers
12	10	Parking sensors (Intelligent Park Assist)	If the rear sensors do not work, check this fuse
23	20	Heated seats and steering wheel	In hybrid versions the denomination may be 25A
30	10	All-round cameras (Around View Monitor)	If the cameras fail, also check the relay R17

Please note: on models with ProPILOT Assist (semi-autonomous driving system) fuse #35 (10A) responsible for the operation of the radar and forward-looking camera. Its failure can lead to system shutdown and an error. P17F0 on the dashboard.

Fuse diagram under the hood: what you need to know

Fuse box under the hood Nissan Murano Z51 responsible for high-power circuits: starter, generator, injection system, cooling fans, etc. The fuses used here are MAXI (large) and standard ATO/ATC.

Features of this block:

• ⚡ Fuse #40 (100A) — main fuse of the power system. Replacing it requires special care (risk of electric shock!).
• ❄️ Fuse #45 (30A) - responsible for climate control and air conditioning compressor. It often fails when the system overheats.
• 🔋 Fuse #50 (50A) - generator circuit. When it burns out, the indicator on the dashboard lights up CHARGE.

In hybrid versions Murano Z51 this block adds fuses for the high voltage system (#60, 120A And #61, 80A). These fuses should only be replaced by a certified technician! Errors in handling high voltage circuits can result in serious injury.

What should I do if fuse #40 (100A) is blown?

If the main fuse is blown #40 (100A), this indicates a serious problem with the power system (such as a short circuit in the wiring harness or a faulty alternator). In this case:

1. Do not try to replace it yourself - diagnostics with a multimeter is required.

2. Check the voltage at the battery terminals (should be 12.6V with the ignition off).

3. Pay attention to the condition of the terminals - oxidation or corrosion may be causing the problem.

If after replacement the fuse blows again, the car must be transported by tow truck to a service center.

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Nissan Murano Z51 - a procedure that you can perform yourself if you follow safety rules. Here are the detailed instructions:

1. Turn off the power: turn off the ignition and remove the negative terminal from the battery (use the key on 10 mm).
2. Find the faulty fuse: Visually inspect fuses for burnt or melted contacts. You can also use the multimeter in continuity test mode.
3. Remove the fuse: Use special tweezers (usually attached to the block cover) or pliers with insulated handles.
4. Install a new fuse: he must have same denomination, just like the original one. Installing a fuse with a smaller or larger rating will result in repeated blowing or damage to the circuit.
5. Check the system operation: Connect the battery and turn on the ignition. Verify that the problem is resolved.

If the fuse blows again after replacement, this indicates short circuit in the circuit. In this case it is necessary:

1. Check wiring for damaged insulation (especially at kinks or near moving parts).
2. Disconnect consumers connected to this circuit (for example, a radio or additional equipment).
3. If the problem persists, contact the service for diagnosis using the wiring diagram.

Common problems and their solutions

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

• 🔊 The audio system does not work (Bose or standard):
  • Check the fuse #7 (15A) in the salon block.
  • If the fuse is good, check the relay R5 (responsible for sound amplification).
  • In models with Apple CarPlay/Android Auto also check the fuse #18 (10A).
• 🔥 Heated seats or steering wheel do not work:
  • fuse #23 (20A) - the most likely reason.
  • If the fuse is good, check the thermostat in the seats (access through the bottom of the upholstery).
  • On hybrid versions also check the fuse #55 (10A) in the block under the hood.
• 📹 All-round cameras do not work (Around View Monitor):
  • fuse #30 (10A) in the salon block.
  • Relay R17 (may “stick” when exposed to moisture).
  • Check the chamber connectors for corrosion (especially after high pressure washing).

If in your Murano Z51 system installed ProPILOT Assist, and an error appears on the dashboard P17F0 (“Driver assistance system malfunction”), in 80% of cases the fuse is to blame #35 (10A) or relay R22. However, before replacing, it is recommended to reset the error via a diagnostic scanner (for example, Launch X431 or Autel MaxiCOM), since sometimes the failure is software in nature.

• MAXI - large-sized (size 34.3 × 8.7 × 29.2 mm).

Incorrect selection may result in poor contact or overheating.

⚠️ Attention: “Universal” fuse sets are often sold on the Internet at a low price. However, such products are often made from low-quality alloys that melt at lower currents than indicated on the case. This can lead to false alarms or, conversely, to a lack of circuit protection during overload.

Troubleshooting: when the fuse is not to blame

The lack of power in a circuit is not always due to a blown fuse. Here are signs that the problem lies deeper:

• 🔌 The fuse is intact, but the system does not work:
  • Check relayresponsible for this circuit (for example, a relay R10 for the system NissanConnect).
  • Use a multimeter to check the voltage at the fuse terminals (should be 12V on one of the contacts when the ignition is on).
  • Check fuse links (located in the wiring harness near the battery).
• ⚡ The fuse blows immediately after replacement:
  • This is a clear sign short circuit in the chain.
  • Disconnect all consumers connected to this circuit and check them one by one.
  • Please note wiring — the insulation often frays in places of contact with the body (for example, under rugs or in doorways).
• 🛠️ The system is unstable (it turns on and off):
  • The problem may be oxidized contacts fuse or relay.
  • Remove the fuse and clean the contacts in the block using contact cleaner (For example, CRC Contact Cleaner).
  • Check mass — poor contact with the body can cause voltage surges.

If you suspect a problem with electronic control unit (ECU), do not attempt to repair it yourself. Modern Murano Z51 are equipped with complex microprocessor systems, and unprofessional intervention can lead to complete failure of the unit. In this case, it is recommended to contact a service center with diagnostic equipment (for example, Nissan Consult III Plus).

⚠️ Attention: In hybrid versions Murano Z51 Some circuits are not protected by fuses, but automatic switches (For example, Hybrid System Main Relay). These elements cannot be replaced; when they are triggered, diagnostics of the high-voltage system is required in a specialized service.

FAQ: answers to frequently asked questions

Is it possible to use a higher rated fuse if the original one keeps blowing?

No, this is extremely dangerous! The fuse is designed for a certain current, and replacing it with a more powerful one can lead to overheating of the wiring and a fire. If a fuse keeps blowing, there is a short circuit or overload in the circuit. It is necessary to find and eliminate the cause, and not mask the problem.

How to check a fuse without a multimeter?

A visual inspection can be used: a blown fuse will have burnt or melted contacts. You can also check the fuse “by light”: bring it to a light source - if the wire inside is broken, the fuse is faulty. However, this method is not always accurate, especially for fuses with transparent housings.

What should I do if after replacing the fuse the system still does not work?

In this case, check:

1. The state of the relay responsible for this circuit.
2. Voltage at the fuse contacts (should be 12V when the ignition is on).
3. Integrity of wiring and connectors (especially if the problem occurred after washing or rain).
4. On-board computer settings (sometimes after replacing a fuse, errors must be reset via a diagnostic scanner).

If the problem persists, contact the service for in-depth diagnostics.

Where can I find the fuse diagram for my version of the Murano Z51?

The official diagram can be found:

• B user manual (section “Fuses”).
• On the cover of the fuse box (usually there is a diagram showing the purpose of each fuse).
• On the website Nissan TechInfo (vehicle registration and VIN required).
• In specialized forums (for example, Nissan Murano Forum).

Please note that patterns may vary by year and market (USA/EU/JP).

Is it possible to change the fuse in the hybrid version of the Murano Z51 yourself?

In hybrid versions It is forbidden to independently interfere with high-voltage circuits (marked in orange). However, fuses for standard circuits (lighting, audio system, etc.) can be replaced independently, following the same rules as for gasoline versions. The main thing is not to touch the orange wires and components with markings HIGH VOLTAGE!
