Introduction: Why the fuse box Qashqai J11 requires attention
Fuse box in Nissan Qashqai J11 (second generation, 2014–2021) is a critical component on which the operation of all electrical equipment of the vehicle depends. The failure of even one fuse can result in inoperative headlights, climate control failure, or engine starting problems. Owners Kashkaya J11 often encounter blown fuses due to power surges, short circuits or natural contact wear.
Unlike the first generation (J10), in Qashqai J11 The fuse box is divided into two main modules: salon (located under the dashboard) and engine compartment (in the engine compartment). In addition, in cars with diesel engines (1.5 dCi, 1.6 dCi) the relay circuit may differ from gasoline versions (1.2 DIG-T, 1.6, 2.0). This article will help you understand the purpose of each fuse, teach you how to check them with a multimeter and replace them without contacting service.
Where is the fuse box located in 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 90% of cases the diagrams are identical.
- 🔧 Main cabin block — located under the instrument panel, to the left of the steering column. To gain access, you need to open the cover by prying it with a flat-head screwdriver or a plastic card.
- 🚗 Additional cabin block — located behind the glove compartment (glove box). You need to remove the glove compartment by unscrewing 4 screws
Torx T20. - 🔥 Engine compartment block - installed next to the battery, under a plastic cover with the inscription
FUSE & RELAY BOX.
On vehicles produced in 2017–2021, an additional relay may be present in the unit under the hood heated windshield (if the machine is equipped with this option). In diesel versions there is also a relay glow plugs, which often fails at sub-zero temperatures.

Diagram and decoding of the cabin unit fuses
Cabin fuse box Qashqai J11 contains up to 50 elements, each of which is responsible for a specific circuit. Below is a table with a breakdown of the most important fuses (numbers may vary slightly depending on the year of manufacture).
| Number | Amps (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| F1 | 10 | Engine management system (ECU) |
Floating speed, error P0606 |
| F10 | 15 | Cigarette lighter, 12V socket | Phone charging does not work, error B2555 |
| F20 | 20 | Climate control unit, heater fan | The stove does not blow, the indicator blinks A/C |
| F30 | 10 | Audio system (Bose or standard) | The radio does not turn on, error U1000 |
| F40 | 15 | Steering column switches (turn signals, wipers) | Turn signals or windshield wipers do not work |
Important: in machines with a system NissanConnect (multimedia complex with navigation) fuse F30 is also responsible for the operation of the rear view camera. If the camera stops turning on when reversing, check this fuse first.
⚠️ Attention: fuse F1 (10A) associated with ECU. If it burns out more than once every six months, this may indicate problems with the wiring or a malfunction of the control unit itself. In this case, diagnostics with a scanner is required (for example, Launch X431).
Engine compartment fuse and relay box: what you need to know
Engine compartment block Qashqai J11 contains fuses and relays responsible for highly loaded circuits: starter, generator, cooling fans, headlights. Here are located main fuse (usually 100A or 120A) and relay fuel pump, which often causes problems with starting the engine.
- ⚡ Fuse F1 (80A) — main fuse of the power circuit. When it burns out, the machine is completely de-energized.
- 🔦 Relay K1 — cooling fan relay. If it fails, the engine overheats.
- ⛽ Relay K5 - fuel pump relay. If there is a malfunction, the engine does not start or stalls after 2-3 seconds.
- 💡 Fuse F10 (30A) - low/high beam circuit. It burns out when installing LED lamps without modifying the wiring.
On diesel versions (1.5 dCi, 1.6 dCi) there is an additional relay in the engine compartment K7 — it controls the glow plugs. If the engine does not start when cold, check this relay and fuse. F15 (50A), responsible for the filament circuit.

How to check the fuse in Qashqai J11 multimeter
Checking fuses with a multimeter is the most reliable diagnostic method. To do this you will need any inexpensive device (for example, DT-830B) and some time. Algorithm of actions:
- Remove the fuse from the socket (you can use the tweezers that came with the car).
- Set the multimeter to continuity test mode (diode or beep icon).
- Touch the probes to the fuse contacts. If it is working properly, the device will emit a sound signal and the screen will show
0.00. - If on the screen
1orOL- The fuse has blown and requires replacement.
You can also check the fuse without removing it by measuring the voltage at its contacts. To do this:
- Turn on the ignition.
- Connect the black probe of the multimeter to ground (for example, to the car body).
- Use the red probe to touch the two fuse contacts one by one. Both should have
12V. If there is voltage on one contact and not on the other, the fuse has blown.
⚠️ Attention: Never test fuses for sparks by shorting the contacts with metal objects. This may cause a short circuit and damage the vehicle's electronics. B Qashqai J11 the control unit is especially vulnerable BCM (Body Control Module), the repair of which costs 30–50 thousand rubles.
Replacing fuses: step-by-step instructions and common mistakes
Replace the fuse in Nissan Qashqai J11 You can do it yourself, but it’s important to follow a few rules:
- Turn off the power. Remove the negative terminal from the battery or turn off the ignition. This will prevent short circuit.
- Use only fuses with the rating specified in the diagram. Installing a fuse with a large amperage (for example,
20Ainstead of10A) may cause a fire in the wiring. - Don't use bugs. Replacing a fuse with a wire or foil is a common cause of car fires.
- Check the cause of the burnout. If the new fuse blows immediately after installation, there is a short circuit in the circuit. Diagnosis required.
Typical replacement mistakes:
- 🔌 Installing the fuse upside down (this is not critical, but may complicate visual inspection).
- 🔧 Using fuses from other vehicles (for example, from Renault). They may not be the correct size or value.
- 🔍 Ignoring corrosion in the block sockets. Oxidized contacts must be cleaned with fine sandpaper or a special spray (for example, CRC Contact Cleaner).
If the fuse blows again, do not rush to install a new one. First check the circuit for a short circuit: turn off all consumers connected to this fuse and turn on the ignition. If the fuse is not blown, connect the consumers one by one to find the problem one.

The fuse box diagram is usually indicated on the back of the box cover. If it is not there, you can download the official manual for your configuration on the website Nissan TechInfo (registration required). An alternative is owner forums, e.g. Qashqai Club Russia, where diagrams for different years of manufacture are posted.
What should I do if, after replacing the fuse, the device still does not work?
Possible reasons:
- The device itself is faulty (for example, the fan motor has burned out).
- Problems with wiring (broken or oxidized contacts).
- The relay that controls this circuit is faulty.
- Faults in the control unit (for example,
BCMorECU).
For diagnostics you will need a multimeter and possibly an error scanner (for example, ELM327).
Is it possible to clean the contacts of the fuse box and how to do it?
Yes, cleaning the contacts helps prevent false tripping of fuses. To do this:
- Remove the fuse box (disconnecting the battery).
- Clean the contacts with fine sandpaper (
P1200) or a special eraser for contacts. - Spray the contacts with a circuit cleaning spray (e.g. Kontakt 60).
