Nissan Note: fuse and relay diagrams with decoding (E11, E12)

Owners Nissan Note sooner or later you have to face the need to replace fuses - be it a blown element in the headlight circuit, cigarette lighter or power windows. But where are the fuse boxes on this model? How to check and replace them correctly without damaging the car's electrical system?

In this article you will find detailed diagrams of fuses and relays for Nissan Note first (E11, 2004–2012) and second (E12, 2012–2020) generations, deciphering their purpose, as well as unique nuances that are not written about in standard instructions - for example, why some relays may be missing in the unit under the hood on basic configurations.

We will also look at typical replacement errors that lead to short circuits and provide a checklist for diagnosing faults. If your Note The ignition key suddenly stops responding or the windshield wipers refuse to work - here you will find the answer to where to start looking for the problem.

Where are the fuse boxes in Nissan Note?

B Nissan Note There are two main fuse blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. Access to it opens after turning three clamps.
• 🚗 Additional block under the hood — located next to the battery (on models with gasoline engines) or in a niche near the air filter (on diesel versions). The block cover is secured with two latches.

By car E12 (2012–2020) there may be another mini-unit in the cabin - it is hidden under the glove compartment and is responsible for the system fuses NissanConnect (if installed). On basic configurations this block is often empty.

Important: on Nissan Note e-Power (hybrid version) the fuse diagram is different - there is a separate block for the high-voltage circuit, located under the rear seat. It is strictly not recommended to interfere with this block yourself. — the risk of electric shock is up to 300 V.

The cabin unit contains most of the fuses responsible for the car's comfort systems. Below is a universal scheme for both generations Note, but please note: on E12 There may be no fuses for options that are not included in your package (for example, F30 — heated seats).

Number	Ampere	Purpose (E11)	Purpose (E12)
F1	10A	Dimensions lamps (left side)	Side lamps (left side) + license plate light
F7	15A	Cigarette lighter	Cigarette lighter + USB port (if available)
F10	10A	Audio system	Audio system + rear view camera
F18	20A	Window lifters	Power windows + sunroof (if installed)
F25	10A	Engine control unit (ECU)	ECU + start-stop system (if equipped)

On E12 from 2016 fuse F32 (7.5A) responsible for the work NissanConnect - if it burns out, the screen of the multimedia system may not turn on or “glitch”. If the problem persists after replacing, check relay R12 in the engine compartment — it is responsible for powering the head unit.

⚠️ Attention: On vehicles with xenon headlights fuse F15 (15A) protects the ignition unit. If it burns out more than once every six months, this may indicate breakdown of high-voltage wires - service diagnostics required.

Underhood fuse and relay box: features

Block under the hood Nissan Note contains fuses and relays responsible for critical systems: ignition, fuel pump, cooling fans. There are several key nuances here:

• ⚡ Fuse F1 (100A, main) — it is forbidden to replace with “bugs”. Its burnout is often associated with a short circuit in the generator circuit.
• ❄️ Relay R3 controls the radiator fan. If it fails, the engine may overheat at idle speed.
• ⛽ Fuse F10 (15A) protects the fuel pump circuit. If it burns out, the engine will not start.

On Note e-Power added in this block:

• 🔋 Fuse F-HV (80A) - high voltage circuit.
• 🔄 Relay R-HV — inverter control.

To access the unit on petrol versions E11 required:

1. Open the hood and disconnect the negative terminal of the battery.
2. Press out the two latches on the unit cover (they often break - use a plastic spatula).
3. Before replacing the fuse be sure to check the voltage on the contacts with a multimeter.

How to check and replace the fuse correctly

Blown fuse in Nissan Note can be determined visually - the thread inside it will be broken or the body will melt. However, for accurate diagnosis it is better to use a multimeter:

1. Set the circuit test mode (diode or “continuity” icon).
2. Touch the probes to the fuse contacts. Beep or zero resistance means it is working properly.
3. If the resistance is infinite, the fuse has blown.

When replacing, follow the rules:

• 🔧 Use fuse same denomination. Setting it “more powerful” will lead to a risk of fire in the wiring.
• 🧲 To remove, use special plastic tweezers (usually attached to the block cover).
• 🔍 After replacing, check the operation of the circuit - if the fuse is blown again, look for short circuit.

⚠️ Attention: On Nissan Note with the system Intelligent Key (keyless entry) fuse F20 (10A) in the cabin unit is responsible for the immobilizer. If after replacing it the car does not start, keys need to be retrained through a diagnostic scanner.

Typical fuse problems and their causes

Owners Nissan Note often encounter repeated blown fuses in the same circuits. Let's look at the most common cases and their causes:

fuse	Symptom	Possible reason
F7 (15A)	Cigarette lighter doesn't work	Short circuit in the socket or connected device with high current (such as a compressor)
F18 (20A)	Power windows don't work	Worn glass guides or moisture getting into the motor
F25 (10A)	Engine stalls, ECU error	Breakdown in the oxygen sensor circuit or control unit malfunction
F10 (15A)	Fuel pump does not work	Short circuit in tank wiring or worn pump

If the fuse F1 (100A) in the engine compartment burns out for no apparent reason, this may indicate:

• 🔋 Generator malfunction (diode bridge breakdown).
• 🔌 Short circuit in the starter circuit.
• 🔥 Problems with the battery (internal short circuit).

In such cases it is required complete electrical system diagnostics — independent repairs without experience can lead to a fire in the wiring.

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

If the new fuse blows instantly when the circuit is turned on, there is a direct short circuit. Algorithm of actions:

1. Disconnect the battery.

2. Inspect the wiring in the area from the fuse box to the consumer (for example, to the cigarette lighter or headlight).

3. Check the integrity of the insulation - often the wires rub against the body in doorways or under the hood.

4. If nothing is visually found, use the “crushing” method: disconnect consumers one at a time until the fuse stops burning. This way you will find the problem area.

Relay in Nissan Note: assignment and verification

Relay in Nissan Note are responsible for turning on powerful consumers: starter, fans, headlights. Their malfunction manifests itself in different ways: from failure to start the engine to flickering lights. Below is a table of the main relays and their location:

Designation	Location	Purpose	Symptoms of a problem
R1	Engine compartment block	Main relay (ECU power supply)	Engine won't start, no spark
R3	Engine compartment block	Radiator fan	Engine overheating, fan does not turn on
R7	Salon block	Windshield wipers	The wipers are jerky or do not turn on
R12	Cabin unit (E12 only)	Multimedia system	The screen does not turn on, there is no sound

To check the relay:

1. Remove the relay from its socket and inspect the contacts for oxidation or melting.
2. Test the winding with a multimeter - the resistance should be within 50–120 Ohm.
3. Apply voltage 12V to control contacts (usually 85 And 86) - there should be a click.

If the relay does not click, it must be replaced. For Nissan Note Fits standard size relays ISO 280 (you can use analogues from Bosch or Hella).

Frequently asked questions about fuses and relays (FAQ)

Is it possible to install a fuse of a higher rating if it constantly blows?

No, it's dangerous! A fuse is designed to protect a specific circuit. Installation, for example, 20A instead of 10A can lead to melted wiring and even a fire. If the fuse blows frequently, look for the cause - usually a short circuit or a faulty consumer (for example, a window lift motor).

Where can I find a fuse diagram for my Nissan Note?

The diagram is usually pasted on the inside of the fuse box cover. If it is not there, download the instruction manual for your model on the website Nissan Global (section Owners → Manuals). For E12 from 2018, the schemes may differ - check by VIN code.

Why did it blow again after replacing the cigarette lighter fuse?

The most common reason is the use of high-consumption devices (for example, car vacuum cleaners or compressors). Also check:

• The integrity of the cigarette lighter socket (often the positive contact shorts to the housing).
• The wiring from the fuse box to the cigarette lighter may be frayed.
• Connected gadgets (for example, DVRs with faulty power supplies).

How to check the starter relay if the car does not start?

Starter relay in Nissan Note located in the engine compartment (R1). To check it:

1. Turn the key to position ON (but don't start it).
2. Listen for a click under the hood - if there is no click, the relay is not working.
3. Swap places R1 and any other identical relay (for example, R3 fan). If the starter starts working after this, the problem is in the relay.

If the relay is OK, but the starter does not turn, check:

• fuse F1 (100A).
• Ground connection on the engine.
• The starter itself (may require repair).

What to do if there is no diagram in the fuse box?

If the sticker with the diagram is worn off or missing, use the following methods:

• Take a photo of the block and find a similar circuit on the Internet upon request Nissan Note [your year] fuse box diagram.
• Compare with photos of blocks from other owners on forums (for example, Nissan-Club.ru).
• Use a multimeter in continuity mode to determine which fuse does what (by elimination).

For E12 from 2016, schemes may differ depending on the market (Europe/Japan) - please check this when searching.
