<em>Nissan Murano</em> fuses: location, diagram and DIY replacement

Nissan Murano is a popular crossover, but even in such a reliable car, electrical circuits periodically fail. Most often, fuses are to blame: they protect the on-board network from short circuits and overloads. If your radio stops working, your headlights don't light up, or your power window fails, first check fuse blocks.

In this article we will look at where the fuses are located on Murano different generations (Z50, Z51, Z52), how to check them with a multimeter, which circuits each element protects, and what to do if the new fuse immediately blows. You will also find unique block diagrams with decoding for Russian and European versions, which often differ from official manuals.

Where are the fuse boxes on Nissan Murano

B Murano There are two main fuse blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. It is accessible by turning the three latches counterclockwise.
• 🚗 Additional block under the hood — located next to the battery (on Z50/Z51) or in a special compartment near the left wing (on Z52). The lid is secured with latches.

On some versions (for example, for the US market) there may be a third block - in the trunk, but in Russian and European Murano it is rare. If your car is equipped with a system Intelligent Key, look for a separate fuse for it in the passenger compartment (usually F30 or F35).

Important: on restyled models (for example, Murano Z51 after 2010) the location of the blocks may differ slightly. If you do not find the fuse according to the diagram, check the sticker on the back of the unit cover - the current wiring is often indicated there.

Fuse diagram Nissan Murano Z50/Z51 (2003–2014)

Below is the transcript interior fuse box for the first two generations Murano. Please note: Fuse numbers may be the same as other circuits in different markets (eg. F10 in the USA it is responsible for the cigarette lighter, and in Europe - for seat heating).

Number	Ampere	Protected circuit	Notes
F2	10A	Body Control Module (BCM)	Responsible for central locking and alarm
F10	15A	Cigarette lighter, 12V socket	Often burns out when using powerful devices
F15	10A	Audio system, navigation	If the radio does not turn on, also check F20
F25	20A	Window lifters	If the mechanism jams, the fuse may burn out
F30	10A	Keyless Entry System	If it doesn't work Intelligent Key, check this fuse and relay K12

B engine compartment fuses for powerful consumers are located:

• ⚡ F30 (30A) - radiator cooling fan. If it burns out frequently, check the temperature sensor or the fan itself.
• 💡 F40 (15A) - right headlight (low beam). When replacing the lamp, do not touch the bulb - grease marks will shorten the service life.
• 🔋 F50 (100A) - generator main fuse. If it burns out, the car will not start - diagnostics of the generator is required.

Where can I find a diagram for Murano Z52 (2015+)?

For the third generation Murano Z52 The fuse diagram has changed. Main differences:

- The cigarette lighter fuse has been moved to the engine compartment (F15, 20A).

- There is a separate fuse for the system Around View Monitor (F22, 10A).

- Control unit I-Key is now protected by a fuse F33 (7.5A).

You can download the complete diagram for the Z52 on the website Nissan TechInfo (registration required).

How to check the fuse for Nissan Murano without a multimeter

If you don't have a tester at hand, you can check the fuse visually or using a simple light bulb. Here are the step-by-step instructions:

1. Remove the fuse tweezers (usually attached to the block cover). Do not use metal objects - the contacts may be damaged.
2. Inspect the thread: if it is torn or there is carbon deposits on the body, the fuse has burned out. Sometimes the crack is only visible at an angle.
3. Checking for spark:
   • 🔦 Turn on the non-functioning circuit (such as headlights).
   • 🔧 Close the fuse contacts with a screwdriver (for a short time!).
   • ✅ If the circuit works, the fuse is faulty. If not, the problem is in the wiring or the consumer.

⚠️ Attention: Never replace a fuse with a "bug" (wire or foil) - this may cause a fire in the wiring. If after replacement the new fuse immediately burns out, look for a short circuit in the circuit!

Why do fuses blow on Murano: top 5 reasons

Frequently blown fuses are a symptom of a malfunction. Here are the most common reasons for Nissan Murano:

1. Short circuit in wiring. Most often it occurs after unqualified repairs (for example, when installing an alarm or radio). Check places where wires rub against the body or fastenings.
2. Consumer fault. For example:
   • 🔊 Speakers with winding short circuit (burns out F15).
   • 💺 Window lift motor with wedging mechanism (F25).
   • 🔥 Rear window heating element (fuse F20, 25A).

Poor contact in fuse box. Oxidized or burnt sockets cause increased resistance and heat. Clean the contacts with alcohol or a special liquid Contact Cleaner.

Using the wrong fuse rating. For example, if you put 15A instead of 10A, the circuit will be overloaded until the more expensive component burns out.

Problems with the generator or battery. Voltage surges (above 14.5V) can damage electronics. Check the voltage at the terminals with the engine running.

On Murano Z52 with the system ProPILOT Assist A common problem is a blown fuse. F40 (10A), responsible for the adaptive cruise control radar. The cause is usually moisture getting into the radar connector (located behind the front bumper).

Step-by-step fuse replacement Nissan Murano

You can replace the fuse yourself in 5 minutes. You will need:

• 🔧 Tweezers (usually included with the car).
• 🔋 A set of spare fuses (preferably original ones) Nissan or high-quality analogues, for example, Littlefuse).
• 📱 Flashlight (for inspecting the block).

Instructions:

1. Turn off the ignition and disconnect the negative terminal of the battery (especially if you are working with the engine compartment).
2. Remove the fuse box cover. On Murano Z50/Z51 it is fixed with three latches, on Z52 - two.
3. Find the faulty fuse according to the diagram (see section above) and remove it with tweezers.
4. Install a new fuse same denomination. Do not use "strengthened" options!
5. Check the operation of the circuit. If the fuse has blown again, see the "Short Circuit Diagnosis" section.

⚠️ Attention: On Murano with a hybrid installation (for example, Murano Hybrid for the Japanese market) there are high-voltage circuit fuses (400V+) in the engine compartment. They can be replaced only wear gloves for electricians and after completely disconnecting the high-voltage battery!

1) Lamp - it could burn out at the same time as the fuse.

2) Relay - it can stick or fail.

3) Wiring - breakage or corrosion in connectors.-->

Short circuit diagnostics: what to do if the fuse burns out immediately

If the new fuse blows when the circuit is turned on, there is a short circuit in the wiring or consumer. To find the problem, follow the algorithm:

1. Disable all consumers this chain. For example, if it burns F25 (window regulators), disconnect the connectors from all four motors.
2. Check the circuit for short circuit:
   • 🔧 Install instead of fuse control lamp (12V, 5W) or multimeter in mode calls.
   • 🔍 If the lamp is on or the multimeter beeps with disconnected consumers - short circuit in the wiring.
   • 🔌 If the lamp does not light, connect consumers one by one until you find the culprit.
3. Inspect the wiring on the subject:
   • 🔥 Melted insulation (especially near connectors).
   • 🐭 Traces of rodents (mice love to chew wires Murano, especially in the area of the harness under the hood).
   • 💧 Corrosion in connectors (a common problem for Muranooperated in wet weather).

On Murano Z51 a common cause of short circuit in the cigarette lighter circuit (F10) becomes connector under the dashboard, which oxidizes over time. To get to it, you need to remove the lower panel on the passenger side (three clips and one bolt under the glove compartment).

If a short circuit is found, but you cannot fix it yourself (for example, the wiring harness inside the door is damaged), contact an auto electrician. For Murano with the system Bose It is especially important to avoid “makeshift” repairs - incorrect soldering can damage an amplifier costing 30,000 rubles or more.

Common mistakes when working with fuses on Nissan Murano

Even experienced car owners sometimes make mistakes that lead to serious damage. That's what can't do:

• 🔥 Use bugs instead of fuses. On Murano this often leads to a fire in the fuse box (especially in the generator circuit F50).
• 🔧 Replace the fuse with a higher rating. For example, instead of 10A set 15A. This may burn out the control unit (for example, BCM or IPDM).
• 💡 Ignore blown fuse F30 (cooling fan). If the fan does not work, the engine will overheat, and repairing the cylinder head will cost 100,000+ rubles.
• 🔋 Don't check relay. On Murano relays often “stick” (for example, K5 - starter relay). This may simulate a faulty fuse.
• 📋 Do not keep records of replacement. If a fuse blows regularly, write down the date of replacement - this will help identify a pattern (for example, after a car wash or rain).

Pay special attention to the fuse F1 (10A) in the cabin unit - it is responsible for NAT-system (audio/navigation). On Murano with Bose its burnout can block the radio with a code request. The code can only be obtained from an official dealer (the cost of the service is about 5,000 rubles).

FAQ: Frequently asked questions about fuses Nissan Murano

Where is the cigarette lighter fuse on Murano Z51?

On Murano Z51 (2008–2014) The cigarette lighter fuse is located in salon block under number F10 (15A). On some versions for the US market it may be in the engine compartment (F15, 20A). If the fuse is good but the cigarette lighter does not work, check the socket for oxidation (a common problem after using high-power devices).

Why on Murano Z52 Does the rear view camera stop working?

On Murano Z52 (2015+) rear view camera protected by fuse F22 (10A) in the cabin block. If it is OK, check:

1. Camera connector (located under the trunk trim, on the left).
2. Relay K15 in the engine compartment (responsible for powering the camera).
3. Radio settings - sometimes the image disappears after resetting the settings.

If the camera works but the image is blurry, clean the lens isopropyl alcohol (do not use aggressive solvents!).

Can fuses from other brands be used?

Yes, but only high-quality analogues. Recommended brands:

• Littlefuse — optimal price/quality ratio.
• Bussmann — premium segment, suitable for critical circuits (for example, IPDM).
• Hella - good for lighting circuits.

Avoid cheap fuses without markings - they may have a low cross-section of the thread, which will lead to false alarms. On Murano with the system ProPILOT It is better to use original fuses Nissan (article 28510-4M000 for dialing).

How to remove the fuse box cover if the latches are broken?

If the fuse box cover latches are broken (a common problem on Murano Z50 after 10 years of operation), proceed as follows:

1. Use a flat-head screwdriver to pry the cover off from the side (not near the latches, so as not to break them completely).
2. If the lid does not budge, heat it with a hairdryer - the plastic will become softer.
3. For temporary fastening, use plastic ties or double-sided tape.

A broken cover can only be replaced as an assembly with a block (article no. 28430-4M000 for Z51, price ~8,000 rubles).

What should I do if the alarm stops working after replacing the fuse?

If after replacing the fuse (usually F2 or F30) the alarm does not respond to the key fob, follow these steps:

1. Check the fuse F35 (10A) - it is responsible for the immobilizer.
2. Reset errors by disconnecting the battery for 10 minutes.
3. If the alarm is standard (Nissan NATS), try retraining the key fob:

   1. Вставьте ключ в замок зажигания.
   2. Поверните в положение ON 6 раз за 10 секунд.
   3. Сигнализация подаст звуковой сигнал — нажмите любую кнопку на брелке.

If the problem persists, the unit may have burned out BCM (located under the torpedo). Diagnostics requires a scanner Consult-III.
