The electrical system of any modern car is a complex network where every part plays an important role in ensuring safety and comfort. For owners Nissan Cube Knowing the location of protective elements becomes critical when sudden failures occur in the lighting, power windows or audio system. A fuse malfunction is often the only cause of failure of a particular unit, and its elimination does not require contacting a specialized service.
Unlike many competitors, the Japanese manufacturer Nissan places its protection units in standard places for the platform, however, the specifics of the body Cube (especially modifications Z11 and Z12) has its own nuances. Before you start disassembling the panels, you need to clearly understand where exactly to look for the required element, so as not to damage the plastic clips or wiring. Competent diagnostics will save time and money, allowing you to quickly return the car to service.
Basic layout of protection units
By car Nissan Cube There are two main locations for placing fuses. The first unit is located in the engine compartment, and the second is located directly in the cabin, on the driver’s side. Each zone is responsible for its own groups of electricity consumers, which allows you to localize the troubleshooting even before the physical inspection of the elements.
The block in the engine compartment is protected by a durable plastic case and is usually responsible for powerful units: the cooling system, generator, headlights and ignition system. This unit is located next to the battery, making it easier to supply high current to the main components. It is accessed by unlatching the cover latches, after which a number of fusible links and power relays can be seen.
The interior unit is located under the dashboard, most often to the left of the steering column. Elements responsible for comfort are hidden here: a cigarette lighter, a radio, interior lighting, power windows and electrically adjustable mirrors. To access this unit, you often need to remove a plastic decorative trim or open a special cover built into the instrument panel. It is important not to use excessive force when removing the panels to avoid breaking the fragile clips.
⚠️ Attention: Before starting any work on checking or replacing fuses, be sure to disconnect the negative terminal of the battery or turn off the ignition to avoid short circuits when touching metal tools.
Diagnosis of burnt out elements
A blown fuse can be identified visually if it is made in a transparent plastic case. Inside there is a thin metal jumper that melts when the permissible current is exceeded. If the jumper is torn or traces of carbon deposits are visible around it, the element must be replaced. In some cases, the fault is not visible to the naked eye, and then the use of a multimeter is required.
Testing with a multimeter is the most reliable diagnostic method. Set the device to continuity or resistance measurement mode. Apply probes to the metal contacts of the fuse on both sides. If the device beeps or shows zero resistance, the element is working. No signal and infinite resistance indicate an open circuit.
Sometimes the cause of electronic failure is not the fuse itself, but poor contact in the seat. Oxidation of contacts or loosening of contacts can simulate element combustion. In such cases, it is enough to clean the contacts with an eraser or lightly press them with pliers, after which installation of a new fuse will not be required.
- 🔍 Always check the integrity of the jumper before replacing, even if visually everything seems intact.
- 🔧 Use only tools with insulated handles when working near the battery.
- 📋 Have a spare set of fuses of different ratings on hand in case of a sudden breakdown.
Instructions for replacement and selection of denomination
The process of replacing the fuse Nissan Cube is extremely simple and does not require specialized equipment. The car often comes with special tweezers, which are attached to the block cover in the engine compartment or in the passenger compartment. If the tweezers are lost, you can use ordinary tweezers with thin jaws, but this must be done extremely carefully.
Pull out the faulty element strictly vertically, without swinging it to the sides, so as not to damage the sockets. The fuse body always indicates the current rating in amperes (A). The color of the case also corresponds to a certain value: red - 10A, blue - 15A, yellow - 20A, and so on. Selecting an element strictly at face value is a safety rule.
If a suitable fuse is not at hand, temporary installation of an element with a lower rating is allowed, but only to check the functionality of the circuit. Installing a fuse with a large rating is strictly prohibited, as this can lead to overheating of the wiring and a fire. Never replace a fuse with a piece of wire or foil - this is a direct path to fire.

Diagram and explanation of the main fuses
For ease of troubleshooting, below is a table with the main consumers protected by fuses in the cabin unit Nissan Cube. Please note that numbering may vary slightly depending on the year of manufacture and model configuration.
| Number (example) | Purpose | Denomination (A) | Color |
|---|---|---|---|
| FR FAN | Heater fan | 20 | Yellow |
| ACC | Audio system, cigarette lighter | 15 | Blue |
| TAIL | Side lights | 10 | Red |
| IGN SW | Ignition, dashboard | 10 | Red |
| ROOM | Interior lighting | 7.5 | Brown |
The block under the hood contains elements responsible for critical engine systems. For example, fuse MAIN or ECU protects the electronic engine control unit. If this element burns out, the car may not start. Also located here are fuses for the ABS system and airbags, which require special attention during diagnosis.
Relays often come with fuses and can also fail. Relay HEAD controls the headlights, and the relay HI is responsible for the high beam mode. If the headlights do not light, check not only the fuse, but also the condition of the relay contacts. Replacing a relay usually does not require disassembling the entire unit; simply remove the faulty one and insert a new one.
☑️ Checking fuses
Common problems and their solutions
One of the common problems in Nissan Cube The cigarette lighter fuse is blown. This often happens due to the use of low-quality chargers for phones or navigators that consume more current than permissible. If you constantly encounter this problem, it is worth checking the quality of the connection in the cigarette lighter socket.
Sometimes there is a situation where the fuse blows immediately after installation. This is a sure sign of a short circuit in the consumer wiring or the circuit itself. In this case, a simple replacement will not help, and in-depth wiring diagnostics will be required using an electrical connection diagram. Ignoring this factor may lead to melting of the wiring harness.
For owners of older models Nissan Cube (Z11) there is an urgent problem of oxidation of contacts in the block due to moisture ingress. If the interior is damp or the seal is not properly sealed, moisture may accumulate in the fuse box. Regularly checking for traces of water and drying the unit will help avoid corrosion and subsequent electronic failures.
What to do if there is no spare fuse?
In an emergency, you can temporarily use a lower-rated fuse from a less critical system (such as a radio or cigarette lighter) to start the engine or turn on the headlights. Under no circumstances take an item with a higher denomination.
⚠️ Attention: If after replacing the fuse it blows again within a few minutes, immediately stop using the vehicle and contact an auto electrician to find the short circuit.
Technical nuances of different generations
First generation Nissan Cube (Z11), produced before 2008, has a simpler fuse box design. In some trim levels, the interior unit may be hidden behind a removable panel that needs to be snapped off with a screwdriver. The second generation (Z12), which appeared in 2008, received a more modern layout, where access to the elements is simplified thanks to a convenient cover with tweezers.
In models with diesel engines (rare for the Russian market), the location of the relay may differ from gasoline versions. The diesel control system has additional relays for heating the spark plugs and the high-pressure fuel pump, which are also protected by fuses. When working with diesel versions, be sure to check the specific diagram for your VIN.
It is important to consider that on vehicles with rich equipment, such as Nissan Cube included 18S or 18Z, the number of current consumers is much higher. This means more fuses and more complex logistics for placing them. Always check the documentation that came with your vehicle, as the factory diagram may be attached to the back of the block cover.
Save the fuse diagram as a photo in your phone or print it out and put it in the glove compartment - this will save time when troubleshooting on the highway.
Prevention and Maintenance
Regularly checking the condition of the electrical system helps prevent sudden breakdowns. Once every six months it is worth inspecting the fuse boxes for oxidation, traces of moisture or overheating. Overheated plastic can become discolored or warped, a clear sign of contact or high current problems.
Cleaning the fuse box contacts is also important. Use special contact cleaning aerosols or regular alcohol. Do not use water or harsh chemical solvents, which may damage the wire insulation or plastic casing. Careful cleaning ensures long service life of the electrical system.
Proper use of electrical equipment reduces the load on the network. Do not connect devices with a consumption higher than 10-15 Amps to the cigarette lighter without installing a separate relay. Use high-quality chargers with surge protection. This will extend the life of your fuses and wiring. Nissan Cube.
- 🛡️ Use moisture-proof sprays to treat contacts in the engine compartment.
- ⚡ Do not overload the cigarette lighter with powerful inverters and compressors.
- 🔋 Monitor the condition of the battery, as voltage surges affect the entire electrical network.
Regular visual inspection and cleaning of fuse contacts prevents 80% of car electrical problems.
Where to find the exact diagram for your car
The most reliable information about the location of fuses can be found in the service documentation for your car. Owners Nissan Cube This possibility is often ignored, but it is the factory diagram that contains all the nuances associated with the year of manufacture and the sales market. You can find many diagrams on the Internet, but they may not match your configuration.
If you do not have a paper version of the manual, refer to official resources or owner forums Nissan Cube. Scans of pages with electrical circuits are often posted there. You can also obtain information from the dealership by stating the vehicle’s VIN code. Specialists have access to databases containing complete information on electrical equipment.
Remember that the markings on the fuse box cover often become erased or unreadable due to ultraviolet radiation and dust. In such cases, the table in this article is a good starting point, but the final test must be made on the actual connection. Use a multimeter to confirm the function of each pin.
How to quickly find a blown fuse without a multimeter?
If you don't have a multimeter at hand, you can use the elimination method. Sequentially remove the fuses associated with the non-working device and try to turn it on. If the device works after removing the fuse, then the problem is not with it. However, this method is less accurate and requires spare elements for testing.
Is it possible to replace the fuse with an analogue of a different color?
The color of the fuse strictly corresponds to its ampere rating. Replacing red (10A) with blue (15A) or yellow (20A) is strictly prohibited, as this will violate the circuit protection. It is permissible to install an element with a lower rating (for example, 7.5A instead of 10A), but only as a temporary measure for testing.
What should I do if the fuse blows immediately after replacement?
This indicates a short circuit in the consumer circuit or wiring. Do not try to solve the problem by installing a larger fuse. You need to find the location of the short circuit, check the insulation of the wires and the serviceability of the device itself (for example, a window regulator or headlight). In difficult cases, the help of a professional electrician will be required.
Where is the tweezers for removing fuses?
Most models Nissan Cube The tweezers are attached to the fuse box cover in the engine compartment. Sometimes it may be located in the cabin, in a special compartment, or inserted into one of the free slots. If you can't find it, check your glove compartment or under the steering column.
