Owners of compact hatchbacks Nissan Note often encounter a situation when one of the electronic devices suddenly stops working: from the radio to the engine control system. In 90% of cases, the problem lies in a burnt-out fuse link or faulty relay, and not in a serious electronic failure. Knowledge of the exact fuse pinouts allows you to quickly localize the fault and return the vehicle to service without a visit to the service center.
Electrical diagram Nissan Note (both the first generation E11 and the updated E12 model) has its own characteristics characteristic of the Japanese automobile industry. The protection units are divided into two main units: one is located in the engine compartment, the second in the driver’s compartment. Each of them is responsible for certain groups of consumers, and they should absolutely not be confused. Incorrect selection of the nominal value can lead to failure of expensive electronic control units.
Localization of protection units in a car
Before starting diagnostics, it is necessary to determine exactly where the main current distribution nodes are located. In the model Nissan Note There are two places for mounting safety blocks. The first block, responsible for high-power circuits and power units, is located under the hood. The second unit, which serves the interior electronics and instrument panel, is located in the dashboard.
The engine compartment protection unit is usually hidden under a black plastic cover located closer to the mudguard or body bulkhead. The cover of this block is often marked with a symbol fuse diagram, however, it may be erased or not contain a transcript in Russian. To access the elements, simply unclip the plastic clips and remove the cover.
The interior block is located on the left side of the steering column, behind the decorative plastic trim. To access it, you need to open the driver's door and find a special plug that is secured with latches. Sometimes removing this cover requires the use of a flat-head screwdriver, but you must act extremely carefully so as not to damage the interior plastic. Inside you will see rows of fuses and relays, numbered in strict order.
⚠️ Attention: Before starting any work to remove fuses, be sure to disconnect the negative terminal from the battery if you plan to manipulate power circuits under the hood. In the cabin, simply turn off the ignition.
It is important to consider that the location of the elements may vary slightly depending on the year of manufacture of the vehicle and the level of equipment. For example, in versions with climate control, the unit may contain additional relays that are not available in basic versions with manually controlled heater. Always check the latest operating instructions for your specific VIN.
Diagram and purpose of the engine compartment block
Engine compartment block Nissan Note is a critically important unit, since high currents pass through it, powering the engine, ignition system and main cooling components. The pinout here is more dense, and the fuses themselves are large in size, designed for high loads. Errors in testing this unit may result in a short circuit in the wiring.
In this block you will find fuses responsible for fuel pump, injection system, engine control unit (ECU) and generator. This is also where the main relays are located, such as the radiator fan relay and the starter relay. The check should begin with a visual inspection of the fuse links: the integrity of the metal jumper inside the transparent body is the main criterion for performance.
To find a faulty element, it is convenient to use a multimeter in continuity mode or a special fuse tester. If you do not want to remove parts, you can measure the voltage at the fuse contacts with the ignition on. The presence of voltage on one contact and its absence on the other with a working load will indicate burnout.

Pinout of interior fuse box
Salon block Nissan Note Contains elements that protect the comfort circuits and the instrument panel. Here are the fuses for window lifters, audio system, cigarette lighter, parking lights and immobilizer system. Owners often pay attention to this particular unit when the radio stops working or the rear window heating does not turn on.
Fuse ratings in the cabin are usually lower than those under the hood, ranging from 5A to 30A. Color coding helps you quickly determine the current strength: yellow - 10A, red - 15A, blue - 20A, green - 30A. However, you should not rely only on color, since over time the plastic can fade in the sun and change shade.
Particular attention should be paid to the cigarette lighter fuse, as this is the most common place for blowouts due to the use of low-quality adapters or chargers. The fuse is also located here ABS and stabilization systems that are critical to traffic safety. If the error light on the instrument panel comes on, check this particular element.

☑️ Checking the interior unit
Nissan Note main fuses table
For ease of diagnosis, below is a summary table with the most commonly used fuses in the car Nissan Note. This information will help you quickly find the right element if the diagram on the block cover is erased or inaccessible.
| Name (Marking) | Denomination (A) | Color | Purpose |
|---|---|---|---|
| IGN1 | 10 | Red | Ignition and sensors |
| FAN | 30 | Green | Cooling fan (cabin) |
| STOP | 10 | Red | Brake lights and brake pedal sensor |

Please note that in different modifications Nissan Note numbering may vary. For example, in early versions of the E11, some circuits were combined, while in facelifted models they are separated to improve reliability. If you do not find the correct fuse in the table, check additional blocks or relays that can be placed separately.
When replacing a fuse, it is extremely important to use a fuse with the exact same rating. Installing a fuse with a larger rating can lead to overheating of the wiring and a fire, while a smaller one can lead to permanent burnout and the inability to operate the car normally. Never short-circuit contacts or use wire in place of a fuse link.
Why does the new fuse blow?
If the new fuse blows immediately after installation, this indicates a short circuit in the circuit. It is necessary to look for damaged insulation, a short to ground, or a malfunction of the consumer itself (for example, a jammed window lift motor). Ignoring this problem and constantly replacing fuses will lead to a fire in the wiring.
Replacement rules and fault diagnosis
The process of replacing the fuse in Nissan Note does not require special tools, with the exception of a plastic tong, which is often attached to the block cover. If the pliers are lost, you can use thin tweezers or carefully pry the element with your fingernail, but this must be done slowly so as not to damage adjacent contacts.
Make sure the load is disconnected before removing the fuse. For ignition driven circuits, turn the key off. For power circuits under the hood, disconnect the battery. Remove the element and carefully inspect it against the light. A blown fuse has a broken metal bridge inside a plastic casing.
If the fuse is visually intact, but the circuit does not work, check it with a multimeter. Set the device to resistance measurement or continuity testing mode and touch the probes to the contacts. An audible signal or a reading close to zero means serviceability. The absence of a signal indicates an internal break, even if it is not visually noticeable.
- 🛠️ Use only original or high-quality analog fuses
- 🔍 Always check the cause of the burnout, and don’t just change the element
- 🔋 Disconnect power before replacing power fuses
- 🧹 Clean contacts from oxides before installing a new element
Keep several spare fuses of different ratings in the glove compartment. This will allow you to quickly fix the problem on the road without searching for the nearest auto repair shop.
⚠️ Warning: Do not attempt to repair the fuse by soldering or twisting. This violates the design protection characteristics and poses a direct threat to the safety of the vehicle and passengers.
Sometimes the problem may not be with the fuse, but with the relay itself. Relays tend to stick or fail electrically. If you suspect a relay malfunction, try replacing it with a similar one from another circuit (if the ratings are the same) to check its functionality. This is a quick way to diagnose without purchasing a new part.
Correctly diagnosing a circuit using a multimeter allows you to avoid false conclusions and save time on finding the true cause of an electrical system malfunction.
Frequent problems and specifics of models
Owners Nissan Note first generation (E11) often encounter the problem of oxidation of contacts in the engine compartment due to moisture ingress. This leads to the fact that even a working fuse may not pass current. It is recommended to periodically inspect the unit and, if necessary, treat the contacts with contact spray or lubricant.
In models with QG15DE or K9K diesel engines, the electrical circuit has additional fuses for the glow plug heating system. These elements often burn out during cold starts in winter. If the engine does not start in cold weather, check these particular fuses, since the heating system is critical for the operation of the diesel engine.
In newer versions Nissan Note (E12 and E13) a CAN bus system is used, where electrical errors can be duplicated on the dashboard in the form of messages. If you see a "Check Engine" message or electrical error, use a diagnostic scan tool to read trouble codes. This will help narrow your search to a specific node.
Symptoms of a faulty relay
If the relay is faulty, you may hear a clicking sound from the fuse box when you turn the ignition on, but the equipment does not operate. It is also possible that consumers (for example, a fan) will switch on spontaneously when the engine is turned off.
Sometimes fuses blow due to power surges in the on-board network. This may be caused by a faulty alternator or voltage regulator. If you notice that fuses are blowing regularly and for no apparent reason, check the voltage at the battery terminals with the engine running. The normal value should be between 13.5–14.5 volts.
Don't forget that some chains in Nissan Note are protected not only by fuses, but also by circuit breakers (automatic circuit breakers) that trip when overloaded. They do not burn out, but simply open and can be reset manually by pressing a button or turning off the power for a short time. Such elements are often found in window lifter circuits.
FAQ: Frequently asked questions
Where is the fuse box located in Nissan Note E12?
The interior block is located to the left of the steering wheel under a decorative cover. The engine compartment is located in the engine compartment, usually on the right (passenger side) or near the mudguard, depending on the year of manufacture.
What should I do if the new fuse burns out immediately?
This is a sign of a short circuit in the circuit. It is necessary to check the wiring for insulation damage, a short to ground, or a malfunction of the consumer itself (motor, lamp). Do not install a fuse of a larger rating.
How to determine the rating of a fuse without an inscription?
The denomination can be determined by the color of the case: red - 10A, blue - 15A, yellow - 20A. You can also measure the resistance or look at the markings on the diagram in the instructions.
Can I use a different color fuse?
No, the color corresponds to the current rating. Using a fuse with a different rating (for example, 20A instead of 10A) may result in overheating and fire in the wiring.
Why doesn't the radio in my Nissan Note work?
Most often this is due to a blown fuse. RADIO or ACC in the salon block. Check their integrity. There may also be a problem with the contacts of the radio connector or in the device itself.
