Electrical system Nissan Tiina is a complex network of nodes, the serviceability of which determines not only comfort, but also driving safety. When a power window, heater, or light stops working, the first thing you need to check is integrity fuses. Many owners are faced with the fact that after purchasing a used car, access to the blocks may be difficult or the markings may be erased.
It is important to understand that each fuse is responsible for a strictly defined circuit circuit. Using an overrated fuse link may result in overheating of the wiring and a fire. In this article we will analyze in detail the location of the blocks, decipher the color coding and give clear instructions for replacing elements on models V10 and V11.
Do not try to find a fault by random search. Systematic approach to verification electricians will save you time and money on repairs. We will look at both the main blocks and hidden elements, access to which requires the removal of decorative panels.
Location of the main protection units in the cabin
Most used fuses in the car Nissan Tiina are located in the cabin, which facilitates their quick access. The main location is a block located on the left side of the dashboard, directly next to the driver. To get to it, you need to open the plastic cover, which is secured with latches.
On the side of the block, on the inside of the cover, there is usually a diagram with symbols. However, in some modifications, especially in the European or Japanese markets, the markings may be in English or Japanese, which requires careful study. Denominations fuse links are indicated by numbers corresponding to the current strength in amperes.
Pay attention to the location of the relay. They occupy the top of the block or separate compartments. Often it is the failure of the relay, and not the fuse itself, that causes malfunction headlights or cooling fan. If the fuse link is visually intact, but the device does not work, the problem may be in switching through the relay.
Control unit in the engine compartment
Under the hood Nissan Tiina there is a second, more powerful protection unit. It is located next to the battery and engine control unit. This block is responsible for starting the engine, operating the generator, windshield wipers and other highly loaded systems. The lid here is secured with more massive latches that require little effort to open.
In this block you will find large sized fuses, often rectangular in shape, with ratings ranging from 30A to 100A. They are called micro fuses or maxi-fuses. They protect power circuits from short circuits due to overload. You need to check them first if your battery is completely discharged or the starter does not work.
When replacing parts, use only new, original parts that meet factory specifications. Corrosion contacts in this block are a common cause of false positives.

Decoding of denominations and color code
For quick diagnosis, you need to know the standard color coding of fuse links. This allows you to visually determine the denomination, even if the numbers on the case are erased or difficult to see. In cars Nissan an international standard is used where the color of the plastic indicates the current strength.
The most common colors and their meanings:
- 🔴 Red - 10A (usually for illuminating devices, sensors)
- 🔵 Blue - 15A (for power windows, cigarette lighter)
- 🟡 Yellow - 20A (for audio system, fans)
- ⬜ White - 25A (for seat heating)
- 🟢 Green - 30A (for windshield wipers)
If you see that a fuse has blown but its color does not match the rating in the diagram, this may indicate an incorrect replacement in the past. Never bet a part with a higher rating than indicated in the documentation. This upsets the balance of the entire electrical circuit.
Sometimes the fuse link looks intact on the outside, but the filament on the inside is burnt out. Use a multimeter to test. Set the device to resistance measurement or continuity testing mode and touch the probes to the contacts on both sides. If the device shows infinite resistance, the part is faulty.
☑️ Check before replacement
Nissan Tiina main fuses table
Below is a summary table describing the most critical circuit elements for the models V10 and V11. Data may vary slightly depending on year of manufacture and configuration, so always check the label on the cap of your unit.
| Designation | Denomination (A) | Purpose | Location |
|---|---|---|---|
| F15 | 15 | Cigarette lighter, 12V socket | Salon (left side) |
| F22 | 20 | Heater fan | Salon (left side) |
| ECU-IG | 10 | Engine control unit | Engine compartment |
| HEAD | 15 | Headlights (low/high) | Engine compartment |
| RAD FAN | 30 | Radiator cooling fan | Engine compartment |
Hidden fuses in the trunk
On some Nissan Tiina trim levels (especially those with a hybrid system or sophisticated audio system), additional fuses may be located in the luggage compartment under the trim. Remove the trunk side panel and check for the small black block. There are often elements responsible for the operation of the sound amplifier and navigation system.
Step-by-step replacement instructions
The replacement process does not require special skills, but requires care and compliance with safety rules. First of all, make sure that the car's ignition off. It is best to remove the negative terminal from the battery to eliminate the risk of a short circuit when manipulating the unit.
There is often a special plastic tweezer inside the block cover for removing fuses. If it is not there, you can use thin pliers, but try not to damage the housing of adjacent elements. Pull out the burnt part and visually inspect the metal bridge inside the transparent housing.
Install a new fuse of exactly the same rating as that indicated on the body of the burned one. Insert it all the way into the slot. If after replacement the new element immediately burns out, it means that there is short circuit. In this case, further operation is impossible until the cause of the short circuit is eliminated.
After replacement, be sure to check the operation of the device for which the fuse was responsible. If everything works, close the unit cover and return the battery to its place. If the problem is not resolved, the problem may not be with the fuse, but with the device itself or the wiring.
Keep blown fuses in a bag to show your electrician. The color of the case and the shape help you quickly select an analogue in the store if the exact denomination is unreadable.
⚠️ Attention: Use only original rated fuses. Installing a part with a higher rating may cause the wiring to melt and cause a fire.
⚠️ Attention: Before replacing, make sure that the cause of the burnout has been eliminated. If the fuse blows again immediately after replacement, stop attempting to start immediately and contact a professional.
Key Point: Always check the cause of the blown fuse. If it burns out due to a short circuit, replacing the part without eliminating the short circuit is useless and dangerous.
Frequent malfunctions and their diagnosis
Owners Nissan Tiina Often faced with the problem of the cigarette lighter fuse blowing. This occurs due to the use of low-quality chargers or adapters with high current consumption. Peak loads exceed the nominal value of 15A, which leads to an instant break in the circuit.
Another common problem is heater fan failure. If air does not flow from the deflectors, check fuse F22 and the corresponding relay. It is also worth paying attention to the resistor of the stove unit, which often fails due to overheating, creating additional load on the circuit.
A malfunction of the window regulators may be associated not only with the fuse, but also with the contacts in the lifting mechanism. Oxidation of contacts leads to current surges. Regular cleaning and lubrication of contacts can extend the life of protective elements.
Features of Japanese and European specification
Cars Nissan Tiina, imported from Japan, may have differences in the electrical circuit compared to European versions. Often used in Japanese versions relay with markings in Japanese, making identification difficult without a translator.
It is important to note that in Japanese cars the standard on-board voltage is the same, but the arrangement of the blocks may be mirrored or offset. For example, the unit in the cabin may be located to the right of the driver or under the steering column. Marking on the covers of Japanese blocks it is often written in small font.
When purchasing spare parts for the Japanese version Nissan Tiina pay attention to the catalog numbers. They may differ from those used in European models. An incorrectly selected fuse may have a different contact shape, making it impossible to install.
Specifics of hybrid versions
If your Nissan Tiina is equipped with a hybrid system, there may be high voltage components present in the fuse box. Never touch orange wires or high-voltage components without special equipment and skills. Work with high-voltage parts should only be carried out in specialized service centers.
Electrical prevention and maintenance
Regular maintenance of the electrical system will help avoid sudden breakdowns. Once every six months, it is recommended to inspect the fuse boxes for oxidation of contacts and signs of overheating. Oxidation often occurs due to moisture getting into the engine compartment.
If any traces of moisture or corrosion are found, use contact cleaner and moisture-proofing spray. This will prevent further damage to the contacts and ensure reliable electrical contact. Do not use common solvents for cleaning as they may damage the plastic.
If you often use additional electrical equipment (navigator, DVR, amplifier), make sure that they are connected through a separate fuse. Connecting directly to the cigarette lighter without protection may overload the main circuit and blow the main fuse.
⚠️ Attention: Do not connect powerful energy consumers (compressors, heaters) directly to the battery without installing a separate fuse in the circuit. This is critical for safety.
FAQ: Frequently asked questions
Where is the fuse diagram for Nissan Tiina?
The diagram is usually glued to the inside of the fuse box cover. One unit is located in the cabin (to the left of the steering wheel), the second is under the hood (near the battery). If the sticker is lost, you can find information in the instruction manual or on specialized forums.
What should I do if the new fuse immediately blows?
This indicates a short circuit in the circuit or a malfunction of the energy consumer itself. Do not attempt to replace it with a higher rated fuse. It is necessary to check the wiring for short circuits and check the functionality of the device that is powered from this circuit.
Can I use a different color fuse?
No, the color corresponds to the face value. Using a fuse of a different color means using a fuse with a different amperage rating, which may cause the wiring to overheat and cause a fire. Always use a part with the same rating as indicated in the diagram.
How to check a fuse without a multimeter?
Visually inspect the metal jumper inside the transparent housing. If it is torn or melted, the fuse has blown. However, sometimes the break may not be visible to the naked eye, so using a multimeter to check the resistance is a more reliable method.
Where to buy original fuses for Nissan Tiina?
Original spare parts can be purchased from official dealers Nissan or in specialized auto parts stores. High-quality universal fuses from well-known brands are also suitable (for example, Bosch, Valeo, Denso), the main thing is to comply with the rating and type of case.
