Owners Nissan Wingroad WY11 generations are often faced with the need to diagnose electrical systems, especially when the headlights, power windows or radio suddenly stop working. In most cases, the culprit of the problem is a burnt-out fuse, which protects the circuit from short circuits and voltage surges. Understanding the design and location of the protection elements is the first step to quickly and independently troubleshooting the problem without contacting a service center.
Power supply system Nissan Wingroad WY11 is built on two main protection units: one located in the engine compartment, and the second located inside the cabin. Each of them is responsible for specific customer groups, and knowing where they are will save you time. Electrical diagram car is not difficult to understand if you have at hand the correct key to decipher the designations and denominations.
It is important to note that ignoring signs of burnout can lead to more serious wiring damage. If you notice that a device is not working, do not immediately change all the wiring or contact an electrician. In 80% of cases, the problem is solved by replacing one small element, the cost of which is negligible compared to repairing the entire system.
Location of protection units in the engine compartment
The first and most powerful fuse box on Nissan Wingroad WY11 is under the hood. It is located on the right side (passenger side), closer to the firewall, and is covered with a black plastic cover. This unit is responsible for protecting high current consuming circuits such as the cooling system, alternator, horn, and fuel pump. Motor block contains both conventional fuse links and power relays.
Opening the lid, you will see a schematic representation of the arrangement of elements pasted on the inside of the lid. This makes it easier to find, but often the label wears off over time or becomes unreadable due to dirt. In this case, you need to rely on the markings on the block itself, or use a multimeter to test the contacts. Power fuses in this block they are rectangular in shape and differ from the salon ones.
- 🔋 Alternator (ALT) - protects the battery charging circuit
- 💡 Headlights (HEAD) - responsible for low and high beam
- 🔊 Signal (HORN) - power supply for the sound horn
- ⛽ The fuel pump (FUEL PUMP) is a critical element for starting the engine
It is important to be careful when working in the engine compartment as this is where hot engine parts are located. Diagnostics must be carried out with the engine off and the ignition off. If you plan to change a fuse while the engine is running, there is a risk of electric shock or short circuit with the tools.
⚠️ Attention! Before removing the engine compartment fuse box cover, make sure the engine is completely cool to avoid burns if you accidentally touch the radiator or manifold.
Interior block and its specifics
The second protection unit is located inside the car and is responsible for the operation of electronic comfort and safety devices. On Nissan Wingroad WY11 it is located under the instrument panel, on the left side of the steering column, near the driver’s knees. To access it, you need to unfasten the plastic cover, which is secured with several latches. Salon block contains smaller fuses designed for lower currents.
This block protects the circuits of the power windows, power mirrors, cigarette lighter, radio and interior lighting. Owners often complain that the cigarette lighter has stopped working - in 99% of cases the fuse in this block is to blame. Decoding denominations here are carried out according to the colors and numbers embossed on the element’s body. Green is usually 30A, yellow is 20A, and brown is 7.5A.
- 📻 Audio system (RADIO) - power supply to the head unit and amplifiers
- 🪟 Power windows (POWER WINDOW) - operation of electric window motors
- 🔌 Cigarette lighter (CIGAR) - power supply to 12V outlet
- 🔦 Interior lighting (DOME) - backlight lamps and instrument panel lighting
Access to this unit may be difficult due to tightness in the driver's feet. It is recommended to use a flashlight and a flathead screwdriver with an insulated handle to remove the cover. Correct replacement requires care to avoid damaging the plastic panel latches, which can be fragile on older vehicles.

Instructions for replacing a blown fuse
The process of replacing the fuse link does not require special knowledge, but must be carried out strictly according to the instructions. First you need to determine which element has failed using a visual inspection or a multimeter. If a visual inspection does not produce results (the bulb is transparent), use the tester in continuity mode, applying the probes to the metal contacts of the fuse. Complete chain should show zero resistance.
To remove the element, use a special clamp, which usually comes with the block and is attached to the side or on the inside of the cover. If there is no clamp, you can use tweezers or needle-nose pliers, but you need to be very careful not to break the plastic case. Installing a new The fuse must be tight, without distortion, to ensure reliable contact.
☑️ Fuse replacement procedure
It is strictly forbidden to use fuses with a higher rating than indicated in the diagram, as well as to twist wires or use bugs. This may cause the wiring to melt and cause a fire. Similar denomination - This is the key to the safety of your electrics. If a new fuse burns out immediately after installation, it means there is a short circuit in the circuit, and further operation of the vehicle is prohibited until the cause is eliminated.
⚠️ Attention! Never install a fuse with a rating higher than specified, even if it “seems to fit” in size. This may cause the wiring to melt and cause a fire.
After replacement, be sure to check the operation of the device for which the new element was installed. If everything is functioning normally, you can close the unit cover and return the plastic cover to its place. Control check should turn the device on and off several times to ensure stable contact.
What to do if there is no suitable fuse?
If you don’t have a fuse of the required rating at hand, you can temporarily use an element with a lower rating (for example, instead of 20A, put 15A), but only to get to the store or service. This will limit the current and may cause the fuse itself to overheat, but will save the wiring. The use of a higher denomination is strictly prohibited.
Table of ratings and assignment of main fuses
To make troubleshooting easier, we have prepared a summary table that will help you quickly navigate the purpose of the protection elements. This table covers the most common circuit failures on the model Nissan Wingroad WY11. Please note that the location may vary slightly depending on the year of manufacture and vehicle equipment.
| Designation | Denomination (A) | Purpose | Color |
|---|---|---|---|
| ECU-IG | 10 | Engine control unit | Red |
| HEAD | 15 | Low beam headlights | Blue |
| HEAD | 15 | Driving lights | Blue |
| STOP | 10 | Brake lights | Red |
| CIGAR | 15 | Cigarette lighter | Blue |
The table shows standard values that are found on most copies. However, always check the markings on your specific vehicle as there may be factory modifications or previous repairs. Color coding is standard for most manufacturers, but do not rely only on color, check the numbers on the case.
Use the rating table as a guide, but always check the actual condition of the fuse before replacing, as external integrity does not guarantee performance.
Diagnosis of problems with relays and ABS unit
In addition to fuses, the electrical system Nissan Wingroad WY11 actively uses relays that control high power current flows. Relays often fail due to burnt contacts inside the housing. If you hear the characteristic clicking sound of the relay, but the device does not work, this may be the problem. Relay test requires replacing it with a known-good analogue from a different circuit (if they are the same).
The ABS system deserves special attention, which has its own separate fuse and relay box, often located next to the main unit in the engine compartment. A malfunction in this circuit can cause the error lamp on the instrument panel to illuminate and disable the anti-lock braking system. ABS diagnostics should be carried out using a diagnostic scanner, since a visual inspection may not reveal a problem in the electronic control unit.
- 🚗 Radiator fan relay - provides engine cooling
- 🔦 Headlight relay - controls the supply of current to the head light
- ⛽ Fuel pump relay - turns on the pump when the engine starts
If you are experiencing intermittent failures of a device that is controlled by a relay, try replacing the relay itself. Relay replacement is a quick and inexpensive procedure that may solve the problem if the fuses are OK.
How to test a relay without a multimeter?
The simplest method is the "replacement method". Find another relay in the block with the exact same number and markings (for example, the horn relay and headlight relay are often the same). Swap them. If the problem has moved to another device, then the relay is to blame.
Maintenance and Prevention Tips
To avoid frequent electrical problems, it is recommended to periodically carry out preventive inspections of fuse boxes. Dirt, moisture and contact oxidation are the main enemies of reliability. Cleaning contacts can be done using an ordinary dry cloth or a special contact cleaner, which is sold in car dealerships. Never use water or wet wipes to clean electrical connectors.
If you often use powerful additional devices (sound amplifiers, heated seats, video recorders), make sure that they are connected through a separate fuse to the battery and not “embedded” in the standard wiring. Incorrect connection often causes the standard fuses to blow and the wiring to catch fire. Always use a safety block with reserve power.
Keep a set of spare fuses of different ratings and tweezers for replacing them in the glove compartment of your car. This will allow you to quickly fix the problem on the road. Spare elements cost pennies, but their absence may force you to wait for a tow truck far from civilization. Regularly check the integrity of all fuses during every oil change or maintenance.
⚠️ Attention! If you notice signs of soot or melting on the fuse body or socket, don't just replace the element. This is a sign of poor contact or overload and requires a detailed check of the wiring and cleaning of the socket before installing a new fuse.
