If your headlights, power windows or radio suddenly stop working, do not rush to go to service: in 80% of cases the problem is solved by replacing the fuse in 5 minutes.

In this article you will find detailed fuse box diagrams for Serena C26 (2012–2022), their location, denominations and purpose of each element. We'll also tell you how to correctly diagnose a fault, avoid replacement mistakes, and what to do if the new fuse blows again. The information is relevant for all modifications, including versions with petrol (MR20DD) and hybrid (2NR-FKE) engines.

Where are the fuse boxes in the Nissan Serena C26

B Nissan Serena C26 provided three main fuse boxes:

• 🔧 Main unit in the cabin — located to the left of the steering column, under the decorative cover. Responsible for most electrical circuits: lighting, climate control, audio system.
• 🚗 Block under the hood — located next to the battery, in a plastic box. High power fuses are concentrated here: starter, generator, cooling fans.
• ⚡ Additional unit in the trunk - found in hybrid versions. Controls the inverter circuits and energy recovery system.

To gain access to the cabin unit, it is enough pull the lid towards you (it is fixed with latches). In the engine compartment, the cover is secured with two plastic clips - they need to be carefully snapped off with a screwdriver. In hybrid versions, the additional unit in the trunk is closed with Torx T20 screws - do not lose them during dismantling!

Diagram and assignment of fuses for the cabin unit

Salon block Serena C26 contains 40–45 fuses (depending on the configuration). Below is a table with the most important elements that most often fail:

Fuse no.	Denomination (A)	Purpose	Symptoms of a problem
F1	10	Body Control Module (BCM), Immobilizer	Central locking does not work, engine does not start
F10	15	Audio system, navigation	The radio does not turn on, there is no sound
F20	20	Window lifters (all 4 doors)	The windows don't work, you can hear the relay clicking
F30	10	Cigarette lighter, 12V socket	Phone charging and cigarette lighter not working
F40	15	Low beam (left headlight)	One headlight does not light, the lamp is working

A complete diagram for your configuration can be found in instruction manual (section "Electrical equipment"). If the manual is not at hand, download it in PDF from the official website Nissan by car VIN code.

⚠️ Attention: fuse F25 (10A) responsible for the work ESP And ABS. If it burns out, the brake warning light on the dashboard will come on and the car may become unstable on slippery roads. Don't ignore this signal!

How to check a fuse with a multimeter or visually

There are three ways to diagnose fuses in Serena C26:

1. Visual inspection. Remove the fuse and look at the light: if the metal thread inside is torn or melted, it is faulty. Disadvantage of the method: Sometimes a thread break is invisible to the naked eye.
2. Check with a multimeter. Switch the device to mode "Provozvonka" (diode icon) and touch the fuse contacts with the probes. If you hear a beep, the circuit is OK.
3. Replace with a known working one. Insert a new one with the same rating instead of the suspicious fuse. If the device works, the problem is solved.

To check with a multimeter, follow the instructions:

1. Выключите зажигание и отсоедините клемму аккумулятора.
2. Извлеките предохранитель пинцетом (он встроен в крышку блока).
3. Подключите чёрный щуп мультиметра к минусовой клемме АКБ (или массе кузова).
4. Красным щупом поочерёдно коснитесь выводов предохранителя.
- Если на обоих выводах напряжение ~12V — предохранитель исправен.
- Если на одном из выводов 0V — предохранитель перегорел.

Turn off the ignition and remove the battery terminal

Wear gloves (fuses may be hot)

Use tweezers from the block cover

Check the voltage with a multimeter or replace it with a new one.

Why fuses blow and how to prevent it

The main reasons for the failure of fuses in Nissan Serena C26:

• ⚡ Short circuit. Most often it occurs due to damage to the wire insulation (for example, after unsuccessful repairs or an accident). Typical risk areas: harnesses under seats and in doorways.
• 🔥 Circuit overload. Occurs when powerful consumers (for example, a compressor for inflating wheels) are connected to the cigarette lighter. fuse F30 (10A) not designed for loads above 120 W.
• 💧 Contact corrosion. Moisture or road salt gets into the fuse box, causing oxidation. This increases resistance and leads to heating.
• 🔄 Poor quality fuses. Cheap Chinese analogues often have too high resistance and burn out even under normal load.

To extend the life of fuses:

• 🛠️ Regularly clean the contacts of the unit from oxides (use WD-40 or specialized cleaners).
• 🔌 Do not connect devices with a power of over 100 W to the cigarette lighter. For compressors and refrigerators, use direct access to the battery through OBD-II connector.
• 🔍 Before replacing the fuse, check the circuit for short circuit. If the new fuse blows immediately after installation, the problem is in the wiring!

Step-by-step instructions for replacing the fuse

To replace the fuse in Nissan Serena C26 you will need:

• Tweezers (found in the fuse box cover).
• New fuse same denomination.
• Flashlight (for inspecting contacts).
• Multimeter (optional, for checking the circuit).

Algorithm of actions:

1. Turn off the ignition and disconnect the negative terminal of the battery.
2. Remove the fuse box cover (in the cabin - pull it towards you, under the hood - unclip the clips).
3. Find the faulty fuse according to the diagram (see section above) and remove it with tweezers.
4. Install a new fuse. Make sure it fits snugly into the socket.
5. Connect the battery terminal and check the operation of the device.

⚠️ Attention: In hybrid versions Serena C26 when replacing fuses in the luggage compartment (e.g. F-HV1, 15A for inverter) required wait 5 minutes after disconnecting the battery. This time is needed to discharge high-voltage capacitors. Failure to do so may result in electric shock!

Common mistakes when working with fuses

Even experienced car owners make mistakes that can lead to serious damage. That's what can't do when replacing fuses in Serena C26:

• 🔥 Use bugs. Replacing a fuse with wire or foil may cause a fire. B Serena C26 it is especially dangerous to do this in chains starter And generator.
• 🔄 Install a fuse of a higher rating. For example, instead of 10A, install 15A. This will not solve the problem, but will only postpone it until the wiring burns out.
• 💡 Ignore contact oxidation. If the fuse keeps blowing, check the block for corrosion. Clean your contacts sandpaper (1000 grit) or special liquid.
• 🔧 Do not check the chain after replacement. If the new fuse blows immediately, there is a short circuit in the circuit. It is necessary to carry out diagnostics with a multimeter or contact service.

Typical error example: owners Serena C26 often placed in the cigarette lighter socket (F30) a 20A fuse instead of the standard 10A, so as not to “change constantly”. As a result, the cigarette lighter connector melts, and it has to be replaced entirely (the cost of a new outlet starts from 3,000 rubles).

FAQ: Frequently asked questions about Nissan Serena C26 fuses

Can fuses from other cars be used?

Yes, if they match Mini Blade size and denomination. Fuses are universal for all brands, but in Serena C26 It is important to observe the current characteristics. For example, a fuse Toyota Corolla 10A suitable for replacement F10 (audio system), but not for F20 (window lifters), where 20A is needed.

Why did all the devices stop working after replacing the fuse?

Most likely you accidentally touched main fuse block (usually F-Main, 80A–100A). It is located in the engine compartment and is responsible for powering all circuits. Check its integrity and tightness of contacts. Also make sure that the battery terminals are connected correctly (plus to plus, minus to ground).

Which fuse controls the heated seats?

B Nissan Serena C26 The fuse controls the heated seats F25 (15A) in the salon block. If it is working, but the heating does not work, check:

• Relay R8 in the same block.
• fuse F35 (10A) — he is responsible for the climate control unit.
• Condition of the wiring under the seats (wires often fray).

What should I do if the fuse blows immediately after replacement?

This is a sign short circuit in the chain. Follow the algorithm:

1. Turn off all consumers (radio, lights, etc.).
2. Check the circuit with a multimeter in "Provozvonka" — if the device emits a signal when the consumers are disconnected, it means there is a short circuit.
3. Visually inspect the wiring from the fuse box to the device. Look for melted insulation or exposed wires.
4. If you don’t find the problem yourself, contact the service for diagnostics. CAN buses (in Serena C26 many circuits are controlled by it).

Do I need to change the relay along with the fuse?

Not always. The relay fails less often, but if the fuse blows frequently, check corresponding relay:

• Click the relay - if you hear a weak click or no click at all, the relay is faulty.
• Swap the relay with a known working one (for example, a cooling fan relay).
• If the device works after replacing the relay, buy a new one (cost: 300–800 ₽).

B Serena C26 Most often relays fail R5 (window lifters) and R10 (audio system).
