Electrical system Nissan Note has a high degree of reliability, but even in modern cars there are power outages. The most common cause of failure of lights, power windows or audio systems is burnout fuse. Owners Nissan Note Often faced with a situation where the usual functions stop working, and the first step in diagnosis is checking the protective elements.
Understanding the block design relay and location fuses allows you to quickly fix the problem without contacting a service center. In this article we will analyze in detail where the main and additional protection units are located, how to correctly interpret their markings and what tools you will need to independently repair the electronics of your Nissan Note.
Location of protection units in the car
In the car Nissan Note (both in the E11 and the updated E12 versions) there are two main places for placing electrical circuit protection elements. The first block is located in the engine compartment, directly under the hood, and is responsible for powering powerful consumers. The second unit is located in the cabin, usually on the left side of the dashboard, next to the driver's door.
The block under the hood is often called main distribution board. It is protected by a sealed lid and contains both fuses, and large relay. Access to this unit requires opening the hood and unlatching the plastic cover latches.
Salon block fuses easily accessible to the owner. To access it, you need to open the side panel of the dashboard on the driver's side or remove the decorative cover, which is often secured with latches. This block contains elements responsible for interior lighting, a cigarette lighter, an engine control unit and other comfort systems.
Fuses in the engine compartment
In the engine compartment Nissan Note are fuses high power, protecting the circuits of the starter, generator, cooling system and fuel pump. These elements are usually larger in size than their salon counterparts and are often designed as JCASE blocks or flat blades. Incorrect replacement can lead to serious consequences, so the denomination must strictly correspond to the original value.
Particular attention should be paid to the main relay nutrition and fuse ignition systems. If the engine does not start, but the starter turns, the problem may lie in these elements. For diagnostics, it is necessary to visually check the integrity of the conductive path inside the transparent body of the element. If the metal inside is melted or melted, the element must be replaced immediately.
List of main circuits protected in the engine compartment:
- 🔋 MAIN — protection of the main power line of the battery.
- 🌡️ FAN — power supply circuit for the engine cooling system fan.
- ⛽ FUEL PUMP — relay and fuse for the high pressure fuel pump.
⚠️ Attention: Never replace a blown fuse with an element with a higher rating (amperage). This may cause the wiring to overheat and cause the vehicle to catch fire.
If you find that fuse burned out again immediately after replacement, this indicates a short circuit in the circuit. In such a situation, independent repair is not recommended, since it requires searching for the location of the insulation breakdown. Continued operation with “constant” replacement of fuses can damage expensive electronic control units.
Interior fuse and relay box
Salon block fuses in Nissan Note Responsible for the operation of comfort systems and peripheral equipment. Here you will find elements that protect the audio system, power windows, climate control unit and interior lighting. This unit is accessed through a removable panel located on the dashboard to the left of the steering wheel.
Inside this block there are also relay, controlling the operation of the windows and central locking. It often happens that the window regulator stops working, but at the same time the fuse visually looks intact. In this case, the problem may be in the relay itself, which requires replacement or checking the contacts.
The layout of the elements inside the interior unit is often marked on the inside of the cover. If the sticker has worn off, you must use the technical documentation. Owners Nissan Note E12 should pay attention to the fact that the location may differ slightly from the E11 version depending on the year of manufacture and configuration.
- Fuses blown
- Relays don't work
- Difficult to find the diagram
- No problem
Table of denominations and purpose of elements
For accurate diagnosis, it is necessary to know the exact purpose of each fuse and relay. Below is a summary table for popular models Nissan Note. Please note that depending on the year of manufacture and the availability of options (for example, heated seats or leather upholstery), the list may vary slightly.
| Name / Designation | Denomination (A) | Purpose of the circuit |
|---|---|---|
| ECU-IG | 15 | Engine control unit (ECU) |
| RR WIPER | 20 | Rear wiper |
| HAZARD | 15 | Hazard alarms and turn signals |
| ROOM | 10 | Interior lighting and lighting |
| POWER | 30 | Power windows |
Using a table allows you to quickly determine which element is responsible for a broken system. For example, if it stopped working cigarette lighter, look for an element marked CIG or POWER OUTLET. It is important to check not only fuses, but also contact groups that can oxidize over time.
⚠️ Attention: It is recommended to check the integrity of the fuse with a multimeter in dial mode, since a visual inspection may not reveal microcracks in the fuse link.
Before replacing any fuse, be sure to turn off the ignition and disconnect all consumers in this circuit to avoid sparks and short circuits when removing the element.
Replacement and diagnostic rules
Replacement fuse - a procedure that does not require special skills, but requires care. The car usually comes with a special plastic tweezer key, which is attached to the unit cover or in a special compartment. If the key is lost, you can use thin tweezers with insulated handles.
The replacement process is as follows: first remove the burnt out element, making sure that it is faulty. Then insert the new one fuse of the same denomination until a characteristic click occurs. If the element does not fit tightly, check the seat for contamination or deformation of the contacts.
If after replacement fuse it burns out again within a few seconds, further operation is prohibited. This is a clear sign of a short circuit. In such cases, it is necessary to check the wiring for damage to the insulation, especially in bends and near metal body elements.
☑️ Preparing to replace the fuse
To check relay The swapping method is often used: a working relay from a circuit where it performs a similar function (for example, a horn relay) is temporarily swapped into the circuit being tested. If the system works, then the problem is in the relay and it needs to be replaced.
