Fuse diagram for Nissan Qashqai J11 (2014–2021): where to look and how to replace

Owners Nissan Qashqai J11 (second generation, 2014–2021) sooner or later face the need to check or replace fuses. The operation of all electrical equipment depends on their serviceability - from headlights and window lifts to the engine control unit. However, find the correct fuse in relay and fuse box not so simple: the manufacturer placed them in several places, and the diagrams in the manual are often not detailed enough.

In this article you will find current fuse diagrams for all modifications of Qashqai J11, including diesel and petrol versions, as well as cars with different levels of equipment. We will look at where the main and additional blocks are located, how to read their markings correctly, and what mistakes are most often made when replacing them. Special attention is paid fuses responsible for critical systems - for example, for work ECU or ABS.

Where are the fuse boxes in the Nissan Qashqai J11

B Qashqai J11 fuses and relays are distributed over three main blocks. Their location depends on the configuration and year of manufacture, but in most cases the layout is standard:

• 🔧 Main unit in the cabin - under the instrument panel on the driver's side. Access to it opens after removing the decorative cover (pull it towards you).
• 🚗 Block under the hood — next to the battery, in a plastic box with a lid. High power fuses are located here (for example for the cooling fan).
• 🔌 Additional block — in the trunk, behind the trim on the left side (relevant for versions with the system Bose or panoramic roof).

On some modifications (for example, with a diesel engine 1.6 dCi) there may be a fourth block - next to the control unit EDC. Its fuses are responsible for the fuel system and turbine. In order not to confuse the blocks, focus on markings on lids: the manufacturer applies a diagram with numbers and denominations.

⚠️ Attention: On vehicles with hybrid installation (For example, Qashqai J11 1.6 DIG-T Hybrid) The fuse box for the high-voltage system is located separately - under the rear seat. It can be identified by orange wires and warning stickers. Do not touch it without special training!

If you are not sure about the location of the block, use service manual for your modification. Body number (VIN) will help clarify the diagram - you can check it through the official website Nissan or services like CarVertical.

Interpretation of fuses in the cabin block

The interior block is the most popular, since fuses for most consumers are concentrated here: lighting, multimedia, power windows, etc. Below is a table with the assignment of each fuse for Nissan Qashqai J11 (valid for most configurations, including Tekna And Acenta).

Number	Rating (A)	Purpose	Notes
1	10	Body control unit (BCM)	Responsible for central locking and alarm
5	15	Cigarette lighter, 12V socket	Often burns out when using powerful devices
10	7.5	Engine control unit (ECU)	Critical! Replacement only with ignition off
15	10	Audio system (Bose)	Versions with NissanConnect have a separate fuse
20	20	Window lifters	If burned out, check the motors for jamming

Please note that on vehicles with all-wheel drive (system ALL MODE 4x4-i) additional fuses appear in the cabin unit to control the transfer case. Their numbers are 25 and 26 (nominal 10A). Also in versions with xenon headlights fuse for ignition unit (Ballast) issued separately (number 30, 15A).

If the fuse blows again after replacement, this is a signal short circuit in the chain. In such cases, wiring diagnostics is required - for example, using a multimeter in calls. Common reasons:

• 🔌 Damage to wire insulation (especially in doorways).
• 💡 Consumer malfunction (for example, window lift motor).
• 🚿 Moisture getting into the connectors (relevant for headlight fuses).

Fuses under the hood: what you need to know

Block under the hood (fuse box) contains fuses for high-power circuits: starter, generator, injection system, etc. Its cover is usually marked with the symbol ⚡ or inscription FUSES. Important: You can only work with this unit when the battery is disconnected (remove the negative terminal!).

Below are the key fuses of this block for Qashqai J11:

Number	Rating (A)	Purpose
30	100	Main relay (IGN)
35	60	Cooling fan
40	50	Injection system (Injectors)
45	80	Generator

The fuse deserves special attention number 50 (30A) - he is responsible for the work ABS And ESP. When it burns out, the icons on the dashboard light up ❄️ And ! in a circle. If replacement does not help, diagnostics of the unit is required ABS scanner (for example, Launch X431).

⚠️ Attention: fuse number 30 (100A) - this is main power relay. Replacing it without first checking the circuit may result in generator overload or even a fire. If it is burned out, first check the condition of the battery and alternator!

On diesel versions (1.5 dCi And 1.6 dCi) in the block under the hood fuses have been added for:

• 🔥High pressure pump (HPFP) - number 55 (20A).
• 💨 Valves EGR - number 60 (10A).
• 🔄 Turbines - number 65 (15A).

Additional units: trunk and hybrid versions

In cars with a rich set of equipment (for example, Qashqai J11 Tekna+) some of the fuses are placed in the trunk. They are responsible for:

• 🎵 Audio amplifier Bose (fuse 10A).
• 🔋 Additional 12V socket in the trunk (15A).
• 🌞 Panoramic roof (20A).
• 📡 Antenna amplifier and GPS-module (5A).

Access to this block opens after removing the trim on the left side of the trunk. The block cover is usually secured with latches - pry it off with a flat-head screwdriver. Do not confuse this block with a relay block (it is located nearby, but has a different marking).

For hybrid versions (1.6 DIG-T Hybrid) the schemes are different:

• 🔋 High voltage battery fuses (HV Battery) - under the rear seat (access only from authorized dealers).
• ⚡ Inverter fuse (Inverter) - 20A, located in the engine compartment next to the block PCU.
• 🔄 Regeneration system fuse - 15A, in the cabin unit (number 28).

⚠️ Attention: In hybrid Qashqai J11 high voltage system (orange wires) is under voltage up to 300V even with the ignition off! It is strictly forbidden to touch components marked with HIGH VOLTAGE without special training.

What to do if there is no fuse box in the trunk?

On basic trim levels (Acenta without options) the additional block may be missing. In this case, the fuses for the audio system and sockets have been moved to the interior unit (numbers 15 and 17, respectively).

How to properly replace a fuse: step-by-step instructions

Replacing a fuse is a simple procedure, but even here there are nuances. Follow this algorithm to avoid errors:

1. Turn off the ignition and remove the key from the lock. For fuses under the hood, disconnect the negative terminal of the battery.
2. Find the faulty fuse. Refer to the diagram on the cover of the block or table from this article. A visually blown fuse has broken thread or blackened body.
3. Use a puller. In the majority Qashqai J11 it is built into the block cover (plastic tweezers). If you don't have one, tweezers or a flathead screwdriver will do.
4. Install a new fuse the same denomination. Never use bugs or fuses with a different amperage!
5. Check circuit operation. Turn on the ignition and activate the consumer (for example, headlights or window regulator).

If the fuse blows again after replacement, this indicates short circuit. As a temporary solution, you can use a fuse with obviously lower denomination (eg 10A instead of 15A) to protect the circuit until the cause is corrected. However, you can’t drive like this for long!

To diagnose a short circuit:

1. Disconnect all consumers in the circuit (for example, remove the connector from the window lift motor).
2. Install a new fuse.
3. Connect the consumers one by one until the fuse blows again - this way you will find the culprit.

Common problems and their solutions

Owners Nissan Qashqai J11 often encounter typical faults related to fuses. Here are the most common cases and ways to eliminate them:

• 🔦 Headlights don't work (low/high beam):

  Check fuses number 7 (10A) And number 8 (10A) in the cabin unit, as well as a relay number 12. If the fuses are intact, but the headlights do not light, check ignition unit (for xenon) or lamps.

• 🔊 Audio system doesn't work:

  Possible causes: fuse number 15 (10A), antenna cable break or firmware failure NissanConnect. Try resetting the radio (hold the button POWER 10 seconds).

• 🚪 Power windows don't work:

  Check the fuse number 20 (20A) and relay number 5. If the problem is in one glass, the motor or the guides are to blame. Lubricate them silicone grease.

• ⚡ Battery won't charge:

  Culprits: Generator fuse number 45 (80A) under the hood or a broken alternator belt. Check the voltage at the terminals with the engine running - there should be 13.8–14.4V.

If the problem persists after checking the fuses, use diagnostic scanner (For example, ELM327). It will show errors in the block BCM or ECU, which may be associated with faults in the circuits. For example, code B2555 indicates a short circuit in the power supply circuit of the control unit.

Where to buy fuses for Qashqai J11

Fuses for Nissan Qashqai J11 are standardized, so they can be bought at any auto store or ordered online. The main thing is to choose quality components, since cheap fakes may melt or fail to operate when overloaded.

Recommended options:

• 🏆 Genuine Nissan fuses (article 28510-4M000 for dialing). Guaranteed quality, but above average price.
• 💰 Bosch or Hella - reliable analogues, comply with the standard ISO 8820-3.
• 🛒 Universal Fuse Kits (For example, Liqui Moly 7666). Convenient for emergencies.

When purchasing, pay attention to:

• 🔢 Denomination (must match the original one).
• 🔌 Housing type: in Qashqai J11 fuses are used mini-blade (small) and maxi-blade (large ones, under the hood).
• 📜 Certification: there must be a sign on the packaging SAE or DIN.

Avoid buying fuses in markets or from dubious sellers. Cheap counterfeits may have incorrect resistance, which will lead to overheating of the circuit. For example, a 10A fuse from an unknown brand can pass up to 15A, which can result in the wiring melting.

FAQ: Frequently asked questions about Qashqai J11 fuses

Is it possible to use a higher rated fuse if the original one keeps blowing?

No! Installing a high amperage fuse may result in fire or failure of electronics. If the fuse blows repeatedly, look for the cause (short circuit or faulty consumer). A temporary solution may be a fuse with smaller nominal (for example, 10A instead of 15A), but only until the fault is eliminated.

How to check a fuse without a multimeter?

Visually: a blown fuse has broken metal thread inside the case. You can also use light bulb tester: connect it to the fuse contacts (with the ignition on). If the light does not light, the fuse is faulty.

Where is the cigarette lighter fuse located?

In the salon block, number 5 (15A). On some versions it is combined with a 12V socket in the trunk. If the cigarette lighter does not work, also check relay number 3 in the same block.

What to do if after replacing the fuse ECU caught fire Check Engine?

This is normal - the control unit needs retraining. Turn off the engine, remove the battery terminal for 5 minutes, then start the car and let it idle for 10 minutes. If the error remains, reset the adaptations with the scanner (for example, Launch CReader).

Is it possible to repair the fuse box yourself if the contacts are melted?

If only the fuse contacts are melted, it is enough to replace it and clean the sockets sandpaper (600 grit). If the block itself has melted, it needs to be replaced. On Qashqai J11 fuse blocks are not repaired - only complete replacement (original article number: 28450-4M000 for the cabin unit).
