The electrical system of a modern car is a complex network where each node plays a role. In the case of Nissan Juke 2012 release, the reliability of electronics directly depends on the serviceability of the protective elements. If the stove fan stops working or the ashtray does not light up, the problem most often lies in a blown fuse.
Many crossover owners Nissan Juke are faced with the need for self-diagnosis when the dealership is far away and the problem requires an immediate solution. Knowing the location of blocks and deciphering color markings can save time and money. In this article we will look in detail at where all the fuses are located and how to check them correctly.
Location of main protection units
On board Nissan Juke In 2012, two main places where fuses were concentrated were installed. The first is located in the engine compartment, and the second is located directly inside the car. Access to them does not require dismantling complex panels, but care must be taken when working with electrical equipment.
In the engine compartment, the unit is located on the right side (passenger side) closer to the windshield. It is protected by a black plastic cover that is secured with latches. This block contains elements responsible for powerful consumers: generator, headlights, cooling fan and engine electronics.
The interior unit is hidden in the dashboard, on the left side of the steering column. To get to it, you need to open the cover located at the end of the instrument panel. Here are the fuses responsible for comfort: power windows, audio system, cigarette lighter and backlight. It is important not to confuse these two blocks, as they have different markings and values.
Detailed description of the engine compartment
Engine compartment block Nissan Juke contains both classic fuse links and more powerful power relays. Visually they differ in shape and size. Large square elements are often responsible for the ignition system or fuel pump, while small colored fuses protect sensors and controllers.
When you open the lid, you will see a diagram printed on the inside of the lid. It shows the location of each element, but sometimes the markings can be erased over time. In such cases, it is necessary to focus on the color of the plastic, which indicates the current strength. Red usually means 10 Amps and yellow usually means 20 Amps.
- 🔋 Check the power relays responsible for starting the engine if the car does not start.
- 💡 Inspect the headlight fuses if one of the lamps stops burning.
- 🌡️ Make sure the element protecting the cooling fan is intact.
Do not ignore the burning smell or darkening of the plastic around the fuse. This may indicate a short circuit in the circuit that has caused overheating. In this case, simply replacing the part will not solve the problem, and wiring diagnostics will be required.
⚠️ Attention: Before opening the engine compartment cover, be sure to turn off the engine and remove the key from the ignition. Working on high voltage circuits with the ignition switch on can result in serious electronic damage or burns.
Salon block and its purpose
Inside the cabin Nissan Juke 2012 fuse box is located in the niche to the left of the steering wheel. He is responsible for all comfort and multimedia systems. It is accessed by snapping off the plastic cover. Inside you will find both standard fuses and control relays.
Most often, owners pay attention to this unit when they have problems with the cigarette lighter or radio. If the 12-volt outlet does not work, the first thing you need to do is check the marked fuse 15A or 20A (usually red or yellow). Also here are elements for electric windows and mirrors.
- 🎵 Check the audio system circuit if there is no sound or the screen does not turn on.
- 🪟 Inspect the window elements if the windows do not respond to the buttons.
- 🔦 Don't forget to check the fuses for the interior lighting and dashboard lighting.
The location of the fuses in the passenger compartment may vary slightly depending on the vehicle configuration. In basic versions, some elements may be missing because the corresponding options are not installed. Always check the current diagram specifically for your instance.
- Engine compartment (engine)
- Salon (comfort)
- Both blocks are the same
- Never checked
Instructions for checking and replacement
The process of replacing a blown fuse is quite simple, but requires care. You will need special tweezers, which are usually located inside the cover of the interior unit, or regular tongs with thin ends. Do not use metal tools that may cause a short circuit.
Carefully remove the fuse by grasping it by the plastic housing. Inspect the metal jumper inside. If it is torn or melted, the element is faulty. If the jumper is intact, the problem may not be with the fuse, but with the consumer itself or the wiring.
☑️ Preparing to replace the fuse
It is strictly forbidden to install a fuse with a higher rating than indicated on the diagram. This can lead to a fire in the wiring, since the cable cross-section is designed for a certain current. Use only analogs that match the current strength and color.
⚠️ Attention: If the new fuse blows immediately after installation, this is a clear sign of a short circuit. Do not try to solve the problem by installing a more powerful element - this is a direct path to fire. Contact an auto electrician immediately.
What to do if the tweezers are broken?
If the original tweezers are lost or broken, you can use eyebrow tweezers or small, fine-tipped scissors. The main thing is to make sure that the tool is clean and does not have sharp edges that could damage adjacent contacts.
Table of denominations and decoding
For ease of perception of information, we have compiled a summary table describing the main colors and their correspondence to current strength. This will help you quickly find your way if the diagram on the cover is erased. Color coding is an international standard, but it is always worth double-checking the numbers on the part body.
| Case color | Current (Ampere) | Typical consumers |
|---|---|---|
| Blue | 15A | Window lifters, fan |
| Red | 10A | Side lights, sensors |
| Yellow | 20A | Cigarette lighter, audio system |
| White | 7.5A | Instrument panel, lighting |
| Green | 30A | Horn, ABS |
It is important to understand that in different models Nissan Juke From 2010 to 2014 there may be slight differences in location. If you have a restyled version, the scheme may differ slightly from the pre-restyling version. Carefully read the markings on the fuse housing.
Before purchasing new fuses, remove the old element and compare it with the new one. Sometimes visually similar parts have different heights or contact shapes, which will make installation impossible.
Diagnosis of complex faults
Sometimes replacing the fuse does not bring any results. This may indicate that the problem is deeper. For example, if the element responsible for the ABS system burns out, the speed sensor or the control unit itself may be faulty. In such cases, professional diagnosis is required.
It is also worth checking the condition of the relay. A relay is an electromagnetic switch that often fails before fuses. If, when you turn on the system, you do not hear a characteristic click of the relay, try replacing it with a known-good similar relay from another circuit (for example, from a windshield wiper).
- 🔍 Check the integrity of the wiring for chafing and exposure.
- 🔌 Inspect the connectors for oxidation or moisture.
- 📉 Measure the voltage at the battery terminals - low charge may cause malfunctions.
In modern cars, electrics are closely connected with electronic control units. Any fault in the circuit can cause errors to appear on the dashboard. Use a diagnostic scan tool to read error codes to pinpoint the problem unit.
Regular checking of fuses and cleanliness of contacts in the blocks is the key to long and stable operation of the electrics of your Nissan Juke.
Features of operation and tips
Owners Nissan Juke must remember that climatic conditions can affect the condition of the electrical system. Humidity and temperature changes contribute to the oxidation of contacts. Periodically conduct a visual inspection of the blocks for signs of corrosion.
If you plan to install additional equipment (for example, powerful audio systems or alarms), be sure to connect it through a separate fuse to the battery. Do not overload standard circuits designed for factory consumers.
Keep a set of spare fuses of different ratings in the glove compartment. This will save you on the road if your headlights or turn signals suddenly stop working. It is better to have an extra set than to be left without light in the dark.
Frequently Asked Questions
