Electrical system of a Japanese hatchback Nissan Cube The first generation (Z10 body) is reliable, but over time it may require the owner’s attention. Most often, problems arise in the form of a sudden failure of the power windows, radio or lighting system. In such cases, the root cause is almost always a burnt out fuse, which acts as a protective barrier for expensive wiring.
You need to know the exact location of the blocks and the ratings of the elements in order to quickly restore the car’s functionality without a service visit. Ignoring signs of failure can result in a short circuit that will damage the controllers and require extensive repairs. Let's figure out how the electrical protection system on the model works Nissan Cube Z10.
Location of fuse boxes in the passenger compartment
By car Nissan Cube In the main Z10 type, you will find two main units responsible for distributing current in the cabin. The first block is located in the dashboard, on the left side of the steering column, on the driver's side. To access it, just open the plastic cover, which is secured with latches.
The second block is located in the engine compartment, but it is often confused with the relay block. It is important to distinguish them, since in the cabin there are elements responsible for comfort and multimedia, and under the hood - for power units and lighting. Electrical unit The interior contains fuses that protect the cigarette lighter, audio system and window control unit.
To search for a specific item you will need fuse diagram, which is usually glued to the inside of the block cover. If the sticker is lost, do not guess by eye - it is better to use the official manual or a proven repair manual.
Features of the engine compartment protection unit
Block located in the engine compartment Nissan Cube Z10, performs the function of protecting the main energy consumers. Here are the elements responsible for the operation of the generator, cooling system, ABS and radiator fans. This unit is accessed by snapping latches on the black plastic housing.
Inside you will see both flat standard fuses and more powerful elements in the form of cylinders or bolt-on blocks. Relay in this zone they are often responsible for turning on the starter and operating the high beam headlights. Checking the contacts here requires greater care due to the high risk of damage to adjacent connectors.
Please note that the engine compartment unit may contain elements designed for high currents (up to 30-40 Amperes). Their burnout most often indicates a serious fault in the circuit, and not just a random power surge.
⚠️ Attention: Before starting any work on the electrical system Nissan Cube Z10 you need to disconnect the negative terminal of the battery. This will eliminate the risk of short circuiting when removing fuses or relays.
Diagnostics and visual inspection of elements
You can identify a burnt element without special equipment, simply by performing a visual inspection. Hold the fuse under a light and look at the metal jumper inside the plastic housing. If it is intact and looks like a continuous arc or line, then the element is working.
If the jumper is torn, melted or has traces of soot, it means fuse burnt out and requires immediate replacement. Do not attempt to repair it by soldering or twisting - this will compromise the circuit protection and may cause a wiring fire.
Sometimes the problem lies not in the fusible element itself, but in the contact group. Oxidation of the legs or loosening of the clamps in the block can cause poor contact, which simulates burnout. In such cases, it is enough to clean the contacts with an eraser or alcohol.
- 💡 Use a flashlight to inspect elements located deep in the block.
- 🔍 Check not only the jumper, but also the integrity of the plastic case for cracks.
- ⚡ If you have a multimeter, check the current transmission in the “test” mode for accuracy.
If visually all elements appear to be in good working order, but the device does not work, the problem may be deeper - in the consumer itself or the wiring. In this case, you should contact a diagnostic specialist.
- Cigarette lighter burnt out
- Power windows don't work
- The instrument panel is flashing
- The radio doesn't work
Replacement procedure and selection of analogues
To replace a burnt-out element, you will need a special plastic clip, which is usually attached to the side of the block cover or on the block itself. If you don't have one, you can use tweezers with plastic tips to avoid damaging adjacent parts.
When selecting a new element, it is critical to maintain the current rating. If a 10 Amp fuse is blown, insert only the same one. Installing a more powerful element ("bug") will cause the wiring to begin to melt, and only a fire will occur. Fuse rating This is not a recommendation, but a strict technical limit.
Color coding helps to quickly determine current strength. Yellow - 20A, red - 10A, blue - 15A, green - 30A. Always check the color chart against the chart, as manufacturers sometimes change colors.
☑️ Instructions for safe replacement
If you don’t have the original element at hand, you can use a temporary analogue with a lower rating, but only for a short-term test. For example, if you need 15A, but only 10A is available, the device may work, but the new element will burn out under starting load. This will help you understand where exactly the short circuit is.
What should I do if the fuse burns out immediately after replacement?
If the new element burns out instantly, it means there is a short circuit in the circuit. Do not continue to install new fuses - this is dangerous. You should check the wiring for any exposed wires or shorts to ground.
⚠️ Attention: It is prohibited to use fuses with a rating higher than that indicated in the diagram. This may cause the wiring harness to melt and cause the vehicle to catch fire.

Below is a table with the most frequently failing elements and their purpose. This information will help you quickly navigate the maze of wires and contacts.
| Item name | Denomination (A) | Purpose | Location |
|---|---|---|---|
| ROOM | 10 | Interior lighting, center console | Salon (left block) |
| ACC | 15 | Audio system, cigarette lighter | Salon (left block) |
| WIPER | 20 | Windshield wipers (windshield wipers) | Under the hood |
| ABS | 30 | Anti-lock brake system | Under the hood |
| HEAD | 15/20 | Low/high beam headlights | Under the hood |
Please note that in different trim levels Nissan Cube Z10 the names may differ slightly (for example, ELEC instead of ROOM). Always refer to the markings on the board itself or the cover.
For elements responsible for illuminating the headlights, separate fuses are often used for the left and right sides. If only one headlight is not working, check the lamp itself first, and then the corresponding fuse.
Keep several spare fuses of different ratings in the glove compartment. This will save you time and money in case of a sudden breakdown on the road.
Common faults and their causes
The most common problem of owners Nissan Cube The cigarette lighter fuse is blown. The reason for this is often low-quality adapters for charging phones or powerful car navigators that consume current above the permissible limit.
Another common malfunction is the failure of power windows. In this case, the problem may be not only in the fuse, but also in wear of the motor or mechanical jamming of the mechanism. If replacing the element does not help, you need to check the lift motor itself.
Sometimes a situation arises when the dashboard goes out. This may be related to the fuse IGN or a contact in the ignition switch. If vibration is the problem, there may be a loose wire somewhere in the circuit.
- 🔌 Use high-quality power adapters with protection against power surges.
- 🔧 Regularly check the condition of the contacts in the fuse box for oxidation.
- 📉 Monitor the current consumption of additional devices connected to the on-board network.
If you notice that fuses are blowing regularly, this is a sign of a system problem. In this case, self-repair can be dangerous, and it is better to entrust the diagnosis to professionals.
Regularly checking the condition of the fuses and cleaning the contacts is the best way to prevent sudden electrical failures on the Nissan Cube Z10.
Additional service details
When servicing electricians Nissan Cube Z10 It is worth paying attention to the relay. Relays are electromagnetic switches that can also fail. Symptoms of a faulty relay: clicks, lack of response to turning on the device, spontaneous operation.
You can check the relay by replacing it with a known good one (if there are identical ones in the block). For example, a windshield wiper relay is often the same housing and rating as a horn relay. Swap them and check the operation.
It is also worth checking the integrity of the ground (grounding) of the body. Poor contact with ground can cause strange behavior of electronics: blinking lamps, incorrect operation of sensors. The mass attachment point is often located under the plastic pads in the driver's or passenger's feet.
Remember that the electrics of Japanese cars Nissan sensitive to the quality of connections. Even slight oxidation can cause big problems. Use special contact sprays to treat connectors during assembly.
