Nissan Murano Z51 - a premium crossover that combines power, comfort and advanced technology. However, even in such a reliable car, problems with electrical equipment periodically arise, and most often they are caused by blown fuses. Without knowledge of the block diagram and the purpose of each element, diagnostics turns into guessing at random - and this is fraught with short circuits or failure of expensive modules.

In this article you will find full decoding of fuses for Murano Z51 (including restyled versions 2018–2023), indicating the exact location of the blocks, ratings and protected circuits. We will also look at typical symptoms of a blown fuse, we’ll tell you how to check and replace them correctly, and warn against common mistakes that can lead to serious damage. We will pay special attention fuses responsible for system operation ProPILOT Assist and hybrid modifications (if applicable).

Where are the fuse boxes located in Nissan Murano Z51?

B Murano Z51 provided three main fuse boxes, as well as additional fusible links in the engine compartment. Their location depends on the year of manufacture and configuration, but in most cases the diagrams are unified:

  • 🔧 Main unit in the cabin — located to the left of the steering column, behind the decorative cover. Accessible without tools, just pull the cover towards you.
  • 🚗 Block in the engine compartment - located next to the battery (on some versions - under a plastic cover near the air filter). Requires removal of battery terminals before use!
  • ⚡ Additional relay block - often installed under the glove compartment or behind the glove box. In hybrid versions, a second unit can be duplicated under the rear seat.

On vehicles with ProPILOT Assist (2018+ years) added fourth block — he is responsible for driver assistance systems and is usually located behind the center console. Its fuses are marked yellow and have a lower rating (5–10 A) than standard ones.

📊 How often do you check the fuses in your car?
  • Only in case of obvious malfunctions
  • Once a year for prevention
  • Never checked
  • I diagnose myself at the slightest failure

Before proceeding with replacement, be sure to turn off the ignition and remove the negative terminal from the battery. In hybrid versions Murano You also need to deactivate the high-voltage system through the service menu or wait 10 minutes after turning off the ignition - this prevents the risk of electric shock.

Interpretation of fuses in the cabin block Nissan Murano Z51

The cabin unit contains fuses responsible for lighting, multimedia, climate control and security systems. Below is a table with current data for models 2015–2023. Please note: on vehicles with Bose Audio And ProPILOT Some items may vary!

Fuse no. Denomination (A) Purpose Signs of burnout
1 10 Body Control Module (BCM), Immobilizer The central locking does not work, the alarm does not work
7 15 Cigarette lighter, 12V socket (front) Charging devices does not work, adapter is burnt out
12 20 Audio system Bose, navigation, rear view camera No sound, black media screen, camera does not turn on
18 10 System sensors ProPILOT Assist (radar, cameras) The error message "Driver assistance system is faulty" is on.
23 25 Heated seats, steering wheel The seats do not heat, the heating indicator blinks

To access numbered fuses 15–20 You may need to remove the plastic trim underneath the steering wheel. In hybrid versions the fuse №18 duplicated in the engine compartment - this is done to back up critical systems.

⚠️ Attention: fuse №12 (audio system) often burns out when connecting non-standard devices through the cigarette lighter. If you are using a DVR or compressor, connect them directly to the battery via a separate fuse!

Fuses in the engine compartment: what do they protect and how to check?

Block under the hood Murano Z51 contains high rating fuses (from 30 to 120 A) responsible for power part of electrical equipment: alternator, starter, injection system, cooling fans and hybrid components (if applicable). Here are located fuse links, which cannot be replaced with standard fuses!

Block Features:

  • 🔋 Fuses F1–F5 (60–100 A) protect power circuits ECU and the main relay. Replacing them requires removing the battery.
  • ⚡ Fuse F10 (50 A) is responsible for operation inverter in hybrid versions. If it burns out, the car will not switch to electric mode.
  • 🚨 Fusible link F20 (120 A) is main fuse the entire on-board network. Its replacement is possible only in the service!

To check the fuses under the hood:

  1. Disconnect the battery (negative terminal first!).
  2. Remove the unit cover by pressing the latches on the sides.
  3. Use a multimeter in continuity mode or visually inspect the fuse for a broken thread.

Disconnect battery (minus → plus)|

Check for moisture in the block|

Inspect fuses for melting|

Test the circuit with a multimeter (resistance should be ~0 Ohm) |

Make sure there is no corrosion on the contacts -->

⚠️ Attention: If the fuse F10 (inverter) burns out again after replacement, this indicates a malfunction of the high-voltage battery or hybrid system controller. Operating the vehicle in this condition prohibited - service diagnostics required Nissan!

Typical problems and symptoms of blown fuses

B Murano Z51 There are several "weak points" associated with fuses. Their burnout is often disguised as other malfunctions, so it is important to know the characteristic signs:

  • 🔦 Headlights or tail lights do not work - check the fuses №3 (cabin block) and F7 (under the hood). A common reason is installing LED lamps without a load corrector.
  • 🎵 Multimedia does not turn on or resets - the fuse is at fault №12 or relay R5 in the salon block. Also check the voltage at the connector Bose (should be 12V).
  • 🚗 The car does not start, the starter does not turn - fuse burned out F3 (100 A) or starter relay. In hybrid versions, additionally check F10 (inverter).
  • ❄️ Climate control does not work - fuse №8 (10 A) or fan relay. If after replacing the fuse burns out again, check the damper motor - it may be jammed.

On vehicles with ProPILOT Assist pay special attention to the fuse №18. Its burnout leads to shutdown:

  • Adaptive cruise control;
  • Lane keeping systems;
  • Road sign recognition.

If after replacing the fuse the system is not restored, you need to reboot ECU through the diagnostic connector or resetting errors with a scanner.

How to reset ProPILOT errors without a scanner?

1. Turn off the ignition.

2. Press and hold the button PROPILOT on the steering wheel.

3. Turn on the ignition (without starting the engine).

4. Hold the button for 10 seconds until the indicator starts flashing green.

5. Release the button and turn off the ignition. Errors will be reset, but only if the problem is fixed (for example, the fuse is replaced).

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

Replacing the fuse in Murano Z51 seems like a simple procedure, but there are nuances here, especially for hybrid versions and cars with ProPILOT. Follow this algorithm to avoid errors:

  1. Turn off the power.
    • For petrol versions: remove the negative terminal of the battery.
    • For hybrids: turn off the ignition, press the button POWER without pressing the brake (mode ACC), then disconnect the 12V battery.
  • Find the faulty fuse. Use the diagram from the manual or the table above. In the interior block the fuses are numbered, in the engine compartment they are marked with letters (F - fuse, R - relay).
  • Remove the fuse. Use the plastic tweezers that came with the car. Do not use metal tools - this may cause a short circuit!
  • Check integrity. Inspect the thread with light or test it with a multimeter. If the fuse is swollen or melted, it must be replaced, even if the thread is intact.
  • Install a new fuse. He must be same denomination! Installing a fuse with a lower rating will lead to its instantaneous combustion, while installing a fuse with a larger rating will result in a risk of fire.
  • Check the operation of the circuit. Connect the battery and turn on the ignition. If the fuse is blown again, there is a short circuit in the circuit and diagnostics is required.

    • For hybrid versions Murano after replacing the fuses in the engine compartment, it may be necessary system initialization. To do this:

    1. Turn on the ignition (without starting the engine).
    2. Press the brake pedal and hold for 5 seconds.
    3. Click the button POWER twice in a row. The system will perform a self-test.
    💡

    If after replacing the fuse №12 (audio system) multimedia does not turn on, try pressing and holding the button POWER on the screen for 10 seconds. This will reset the settings Bose to factory ones.

    Common mistakes when working with fuses and how to avoid them

    Even experienced car owners make mistakes that lead to serious damage. Here are the most common ones and how to prevent them:

    • 🔥 Using "bugs". Replacing a fuse with a wire or foil may result in fire! B Murano Z51 it is especially dangerous to do this with chains ProPILOT and a hybrid system - the voltage there reaches 300 V.
    • 🔧 Replacing the fuse without finding the cause. If the fuse blows repeatedly, there is a short circuit in the circuit. For example, for a cigarette lighter fuse (№7) A common cause is a damaged wire in the cup holder.
    • ⚡ Ignoring fuses. Inserts F20 And F25 in the engine compartment cannot be replaced with standard fuses. Their burnout requires contacting service.
    • 📱 Diagnostics without disconnecting the battery. In hybrid versions, this may result in activation of the high voltage system and electric shock. Always follow the shutdown order: minus first, then plus.

    Pay special attention to fuses associated with system ProPILOT Assist. Replacing them without resetting errors may result in false emergency braking or disabling cruise control. If after replacement the icon lights up on the dashboard ! in the triangle, follow the initialization procedure (see spoiler above).

    ⚠️ Attention: On vehicles with NissanConnect (multimedia system) fuse replacement №12 may lead to reset of paired devices (phone, key fob). Save your pairing codes in advance or be prepared to set them up again!
    💡

    Never replace fuses in Murano Z51 to analogues with a different rating - this can damage control units, the cost of repairs of which reaches 100,000+ rubles.

    FAQ: Frequently asked questions about fuses Nissan Murano Z51

    Can fuses from other cars be used in Murano Z51?

    Yes, but only if they match three criteria:

    1. The same denomination (for example, 10 A instead of 10 A).
    2. The same type (knife, miniature or standard).
    3. Same quality of contacts (original ones preferred Nissan or brands Littlefuse, Bussmann).

    In hybrid versions, fuses for high voltage circuits (F10, F15) should be only original — they have a special coating for arc protection.

    Why is the cigarette lighter fuse (№7) burns out every month?

    Most often this is due to:

    • Using powerful devices (compressors, refrigerators) through the cigarette lighter. Their current consumption exceeds 15 A.
    • Short circuit in the cigarette lighter wire (often frays under the plastic cover).
    • Malfunction of the 12V socket (oxidation of contacts or moisture ingress).

    Solution: Install an additional outlet with a separate fuse (20-25 A) or use a power strip with overload protection.

    How to check a fuse without a multimeter?

    There are two ways:

    1. Visual inspection: remove the fuse and look at the light - if the thread inside is broken or the fuse is swollen, it is faulty.
    2. Replacing with a known good one: take a fuse of the same rating from another circuit (for example, №5 - spare) and install it instead of the one being tested. If the device worked, the fuse was blown.

    For fuses in the engine compartment, visual inspection is unreliable - it is better to check them.

    What to do if after replacing the fuse F10 (inverter) hybrid system not working?

    This indicates:

    • High voltage battery malfunction;
    • Problems with the inverter controller;
    • Open circuit in the power supply.

    DIY repair prohibited - service diagnostics required Nissan using a scanner Consult-III+. Operating the vehicle in this condition may result in battery damage (replacement cost - from 500,000 rubles).

    Where to find the fuse diagram for your version Murano Z51?

    Schemes differ depending on the year of manufacture and configuration. Sources:

    • Original instruction manual (section "Fuses").
    • Electronic catalog Nissan (nissan-techinfo.com) - registration required.
    • Sticker on the back of the fuse box cover (valid for 2018+ models).
