Introduction: Why know the fuse pinout?

Electrical system Nissan Qashqai is a complex organism where each fuse plays the role of a “safety valve.” Without knowing their location and purpose, fault diagnosis becomes a guessing game. For example, if your cigarette lighter or headlights stop working, the problem may lie in a blown fuse F37 (20A) or relay K12 - but how to check this without a diagram?

In this article we will look at all fuse blocks for generations J10 (2006–2013), J11 (2013–2021) and J12 (from 2021), including mounting block in the cabin, block under the hood And additional relays. You will find out which fuse is responsible for start-stop system (only for J11 with 1.6 dCi engine), how to check the cooling fan relay and why you can’t replace fuses with bugs.

Where are the fuse boxes located in Nissan Qashqai?

Depending on the generation and configuration, in Qashqai there can be from 2 to 4 fuse blocks. Their main locations:

  • 🔧 Mounting block in the cabin: Under the instrument panel on the driver's side (to the left of the steering column). To gain access, you need to snap off the plastic cover.
  • 🚗 Block under the hood: next to the battery (on J10 and J11) or in a special compartment near the windshield (on J12).
  • ⚡ Additional relay block: on J11 and J12 can be located behind the glove compartment or under the center console.

On Qashqai J12 (2021+) the block under the hood is often hidden under a plastic protection - it needs to be removed by pressing 4 latches. In some configurations (for example, with ProPilot) there is also a fuse box for driver assistance systems.

Pinout of the mounting block in the cabin (J10, J11, J12)

The most popular unit is the salon unit. Below is a table with the assignment of fuses for Qashqai J11 (2013–2021), since this is the most common generation. For J10 And J12 The diagrams will be different - you will find them in the following sections.

Fuse no. Denomination (A) Purpose Notes
F1 10 Engine control system (ECU) If burned out, the engine may not start
F10 15 Audio system, navigation Also responsible for USB port and Bluetooth
F20 10 ABS sensors If there is a malfunction, it lights up ABS on the dashboard
F37 20 Cigarette lighter, 12V socket Often fails due to the connection of powerful devices
F45 15 Window lifters If all the windows do not work, check this relay

⚠️ Attention: On Qashqai J11 with diesel engine 1.5 dCi fuse F3 (10A) is responsible for injectors. Replacing it with a fuse of a higher rating may result in damage to the engine control unit (ECU).

Fuse box under the hood: diagrams and features

Engine compartment block Nissan Qashqai is responsible for high-power circuits: cooling fans, starter, generator and ignition system. On J10 it is located next to the battery, on J11/J12 — in a plastic box near the windshield.

Key fuses under the hood:

  • 🔥 F1 (80A) — Main fuse (megafuse). When burned, it turns off the entire on-board network.
  • ⚡ F5 (40A) — Electric cooling fan. If it burns out, the engine overheats.
  • 🔋 F10 (100A) — Generator. If there is a malfunction, the battery will not charge.
  • 🚗 F15 (30A) — ABS/ESP. Associated with fuse F20 in the salon.

⚠️ Attention: On Qashqai J12 with a hybrid installation (e-Power) there is a separate fuse in the engine compartment F30 (150A) for high voltage system. Strictly prohibited touch it without special preparation - the voltage in the circuit exceeds 200V!

How to check megafuse (F1)?

A megafuse is a large fuse (usually 80–120A) located in the engine compartment. To check:

1. Disconnect the battery.

2. Remove the fuse with tweezers (it may be under the plastic cover).

3. Visually inspect for burnt contacts or broken plate.

4. Ring the multimeter in the “dialing” mode - the resistance should be close to 0.

If the megafuse is burned out, the cause may be a short circuit in the main circuit (for example, in the wiring harness under the hood).

Fuse pinout for Nissan Qashqai J10 (2006–2013)

Qashqai J10 is the first generation of the crossover, and its electrical circuit is simpler than that of subsequent models. In the salon block there is only 38 fuses (vs. 45+ on J11). Features:

  • 🔌 Fuse F25 (10A) is responsible for immobilizer. If it burns out, the car will not start, and the key indicator on the dashboard flashes.
  • 🎵 F30 (15A) - audio system and climate control. If it fails, the air conditioner stops working.
  • 🚘 F35 (10A) — parking sensors (if installed).

In the engine compartment J10 there is no megafuse - its role is played by a fuse F1 (60A), which protects the circuit from the battery to the interior unit. If it burns out, the machine is completely de-energized.

💡 Advice: On J10 relay often fails K7 (ignition relay). If the starter does not turn, but the dashboard works, check this relay - it is located in the passenger compartment next to the fuse F1.

Pinout differences for Nissan Qashqai J12 (from 2021)

Qashqai J12 received a completely updated electrical architecture. Appeared here:

  • 🤖 Fuse box for ADAS systems (located behind the glove compartment). Responsible for cameras, radars and ProPilot.
  • 🔋 Additional relay block for the hybrid version (e-Power).
  • 📱 Wireless charging fuse (F42, 15A).

In the salon block J12 fuse F22 (10A) is responsible for keyless entry system (Intelligent Key). If it burns out, the car does not respond to the door open button.

⚠️ Attention: On Qashqai J12 with e-Power Do not disconnect the battery without first turning off the ignition and waiting 5 minutes. Otherwise, the calibration of the hybrid system may be reset, and it will have to be reprogrammed at the service center.

💡

If the parking sensors on J12 stop working, check not only fuse F35, but also relay K15 in the engine compartment. Often the problem lies in oxidized relay contacts - they can be cleaned with alcohol.

How to properly replace a fuse or relay?

Replacing a fuse seems like a simple operation, but there are nuances that will help you avoid serious problems:

  1. Turn off the power. Always remove the negative terminal from the battery before working on fuses (except for testing under voltage).
  2. Use tweezers. Do not try to pull out the fuse with your fingers - this may damage the contacts of the unit.
  3. Check the denomination. Install a fuse exactly the same denomination, which is burnt. For example, if you install 15A instead of 10A, this may lead to melting of the wiring.
  4. Diagnose the cause. If the fuse blows repeatedly, look for a short in the circuit (for example, in the wiring harness under the seat).

To replace the relay:

  • 🔍 Compare the old and new relay - they must match in size and contacts.
  • 🔧 If the relay “sticks” (does not click when shaken), it needs to be replaced.
  • 🛠️ Relay contacts can be cleaned with an eraser or alcohol if they have oxidized.

⚠️ Attention: On Qashqai with the system Start-Stop (engine 1.6 dCi) relay K20 is responsible for turning off the generator when braking. If it fails, the system Start-Stop stops working and an error message appears on the dash "Check Auto Stop".

💡

Never use "bugs" (homemade jumpers) instead of fuses! This can cause wiring fires, especially on high-load circuits (such as the cooling fan or starter).

Common problems and their solutions

Here are the typical faults associated with fuses and relays in Nissan Qashqai, and ways to eliminate them:

Problem Possible reason Solution
Low beam headlights do not work Fuse burned out F28 (10A) or relay K10 Also check the lamps and contacts in the headlight unit
Cigarette lighter doesn't work fuse F37 (20A) or oxidation of socket contacts Replace fuse and clean contacts
The car does not start, the starter does not turn fuse F1 (10A, ECU) or relay K7 (ignition) Check also the battery and starter contacts
Power windows don't work fuse F45 (15A) or relay K18 Also check the window motors (they often jam)

💡 Advice: If the problem remains after replacing the fuse, check fuse of the same rating in the engine compartment - some circuits are duplicated. For example, power to an audio system can go through F10 in the cabin and F20 under the hood.

FAQ: Frequently asked questions about fuses Nissan Qashqai

Is it possible to use a larger fuse if the standard one blows?

No! The fuse is designed for a certain amperage, and if you install a more powerful one, this can lead to melting of the wiring or even a fire. If the fuse blows repeatedly, look for the cause (short circuit or overload in the circuit).

Where to find the fuse diagram for your version Qashqai?

The diagram is usually indicated on the back of the mounting block cover. If it is not there, download the instruction manual for your year of manufacture on the official website Nissan or on forums (for example, qashqai-club.ru).

Why does it blow again after replacing the cigarette lighter fuse?

This indicates a short circuit in the circuit. Common reasons:

  • Damaged wire in the harness under the center console.
  • Short circuit in the 12V socket (for example, due to metal objects).
  • A faulty charger or other device connected to the cigarette lighter.

You need to test the circuit with a multimeter or contact service.

How to test a relay without replacing it?

You can test the relay by ear - when activated it should make a click. You can also ring its contacts with a multimeter:

  1. Set the multimeter to dialing mode.
  2. Connect the probes to the contacts 85 And 86 (relay coil). There must be resistance 50–120 Ohm.
  3. Apply 12V to the contacts 85 And 86 - there should be a clicking sound.
  4. Check the resistance between 30 And 87 - in a closed state it should be close to 0.

What to do if the megafuse (F1) in the engine compartment burns out?

Megafuse burns out only when there is a serious short circuit in the main circuit. Self-replacement is possible, but necessarily you need to find the reason:

  • Check the wiring harness from the battery to the interior unit for damage.
  • Inspect the battery terminals - oxidation or poor contact can cause current surges.
  • If you are not sure, contact the service, as diagnostics require special equipment.

After replacing the megafuse do not connect the battery immediately - First check the circuit for a short circuit.
