Nissan Note E12: location of fuses and relays (2013–2020) with decoding

Introduction: Why Know the Fuse Diagram Nissan Note E12

Fuses in Nissan Note E12 (2013–2020 model year) are small but critical elements that protect the vehicle's electrical circuits from overloads and short circuits. Without them, even a minor short circuit in the wiring could lead to a fire or failure of expensive electronic modules. Owners Note E12 Often you have to deal with blown fuses due to malfunctions of the lighting, climate control or multimedia system - and here knowing their location saves time and money.

Unlike previous generations Nissan Note, model E12 received an updated electrical architecture with two main fuse blocks: one in the cabin (under the steering wheel), the other in the engine compartment. In this case, the fuse diagram may differ slightly depending on the configuration (Visia, Acenta, Tekna) and year of manufacture. For example, in cars from 2016–2020, additional fuses for systems appeared NissanConnect and rear view cameras.

This article will help you figure out which fuse is responsible for which function, how to replace it correctly, and what to look for when diagnosing electrical faults. We will also look at common mistakes that owners make when working with fuse blocks, and give recommendations on choosing quality spare parts.

Where are the fuse boxes located in Nissan Note E12

B Nissan Note E12 There are two main locations for fuses and relays:

• 🔧 Salon block — located to the left of the steering column, behind the plastic cover. To gain access, simply turn the three latches counterclockwise and remove the cover.
• 🚗 Engine compartment block — located next to the battery, under the black plastic cover. To gain access you will need to release two latches on the sides.

In some configurations (for example, Tekna with the system Around View Monitor) there may be an additional mini fuse box behind the glove compartment or under the center console. Its presence depends on the year of manufacture: in cars before 2017 it is less common.

It is important to consider that the fuse diagram in Note E12 with gasoline engines (HR12DE, HR16DE) and diesel (K9K) may vary. For example, diesel versions have added fuses for the fuel heating system and valve EGR.

Decoding the fuses of the cabin unit

Cabin fuse box in Nissan Note E12 contains most of the elements responsible for the car’s comfortable systems: lighting, audio system, power windows, etc. Below is a table with a breakdown of the main fuses for the 2013–2020 version (valid for most trim levels).

Number	Denomination (A)	Purpose	Notes
F1	10	Body control unit (BCM)	Responsible for the operation of the central locking and alarm system
F7	15	Cigarette lighter	Often burns out when using powerful devices (for example, car vacuum cleaners)
F10	10	Audio system (NissanConnect)	In complete sets Tekna also responsible for navigation
F15	20	Window lifters	When it burns out, all the glass stops working at the same time.
F23	15	Interior and trunk lighting	Includes door lamps and dome light

Please note that in machines with the system Intelligent Key (keyless entry) fuse added F18 (10A), responsible for the operation of the immobilizer. Its failure may result in the car not starting, despite a working battery.

Engine compartment: fuses and relays

Engine compartment block Nissan Note E12 contains fuses and relays responsible for critical systems: engine, ignition system, cooling fans, etc. Here the fuse ratings are higher (up to 100A), so when replacing it is important to use only original or certified analogues.

Particular attention should be paid to the following elements:

• ⚡ Fuse F30 (30A) - responsible for the work ECU (electronic engine control unit). Its burnout can lead to failure to start the engine.
• 🔥 Relay K5 — controls the operation of the fuel pump. If there is a malfunction, the engine will stall or not start.
• 💨 Fuse F40 (40A) — powers the radiator cooling fans. Burnout causes the engine to overheat.

In diesel versions Note E12 added:

• 🛢️ Fuse F35 (20A) — fuel heating system.
• 🔄 Relay K12 - valve EGR (exhaust gas recirculation).

Important: in the engine compartment fuse F25 (100A) is responsible for the generator. Replacing it requires disconnecting the battery, since high current can lead to burns if handled carelessly.

How to check the relay for functionality?

To check the relay, just listen to its operation: when you turn on the ignition, a working relay makes a slight click. You can also replace a suspicious relay with a known good one (for example, with the same numbers from the block).

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

Replacing the fuse in Nissan Note E12 - a simple procedure, but requiring accuracy. Here is the sequence of actions:

1. Turn off the ignition and turn off all electrical appliances (headlights, radio, etc.).
2. Remove the fuse box cover (in the passenger compartment or under the hood).
3. Find the faulty fuse. Usually it has a burnt-out thread (visible in the light) or a melted body.
4. Remove the fuse with special pliers (included with the car) or tweezers. Never use metal tools - this may cause a short circuit!
5. Install a new fuse same denomination. Using a high current fuse may cause a fire.
6. Check the operation of the system for which the fuse was responsible.

If the fuse blows again after replacement, this indicates a short circuit in the circuit. In this case, you need to contact an auto electrician to diagnose the wiring. Common reasons:

• 🔌 Damage to wire insulation (especially in doorways).
• 💡 Consumer malfunction (for example, short circuit in the window lift motor).
• 🌧️ Moisture getting into the connectors (relevant for trunk lighting fuses).

Typical faults and their causes

Owners Nissan Note E12 often encounter recurring problems with fuses. Here are the most common cases:

⚠️ Attention: If your car's fuse frequently blows F7 (15A) (cigarette lighter), check the socket for oxidation or connected devices. Using uncertified chargers may result in voltage surges.

1. Power windows don't work

Most often the fuse is to blame F15 (20A) or relay K3 in the salon block. If replacing the fuse does not help, check:

• 🔧 Condition of the wiring in the doors (the wires in the corrugation are often frayed).
• 🔄 The performance of the window lift motors (you can hear clicks when you press the button).

2. Cooling fan does not turn on

The problem may lie in the fuse F40 (40A) or relay K9 in the engine compartment. Also worth checking:

• 🌡️ Coolant temperature sensor (if faulty) ECU does not give a signal to turn on the fan).
• 🔌 Fan connectors for corrosion.

3. The audio system does not work (NissanConnect)

If the radio does not turn on, check the fuse F10 (10A) and relay K6. In configurations with navigation, the fuse may also be at fault. F11 (7.5A)responsible for the module GPS.

Valeo	720208	Impact-resistant housing, suitable for extreme temperatures	350–550 ₽

When purchasing analogues, pay attention to:

• 🔍 Rated current - must exactly match the original.
• 🔧 Fuse type - in Note E12 miniature fuses are used (ATO/ATC) and maximum (MAXI).
• 📌 Quality of contacts - cheap fuses may have poor contact, which leads to heating.

⚠️ Attention: Fuses labeled "Fuse"without indicating the brand often turn out to be fakes with an underrated value. Such parts can burn out at the slightest load or, conversely, fail to operate in the event of a short circuit.

Frequently asked questions (FAQ)

Is it possible to use a higher rated fuse if the original one blows frequently?

No, this is extremely dangerous! The fuse is designed for a certain current, and increasing it can lead to a wiring fire. If a fuse frequently blows, you need to look for the cause (short circuit or faulty consumer), and not increase the rating.

Where to find a fuse diagram for your configuration Nissan Note E12?

The fuse diagram is usually indicated on the back of the block cover. If it is not there, you can download the official instruction manual for your equipment on the website Nissan or use online spare parts catalogs (for example, Elcats or EPC).

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

Possible reasons:

1. The device itself is faulty (for example, the window lift motor has burned out).
2. The problem is in the relay - try replacing it with a known good one.
3. Broken wiring or oxidation of contacts.

For diagnostics, you will need a multimeter or the help of an auto electrician.

How to check a fuse without removing it from the block?

You can use a multimeter in continuity mode: touch the probes to the fuse contacts. If a beep sounds, the fuse is good. Also, some fuses have an indicator (red dot) that dims when it blows.

Do I need to disconnect the battery when replacing fuses?

To replace fuses in salon block It is not necessary to disconnect the battery (just turn off the ignition). However, when working with engine compartment block (especially with high rated fuses) it is recommended to remove the negative terminal for safety.
