Owners Nissan Qashqai J11 (second generation, produced 2014–2021) sooner or later they are faced with the need to check or replace the fuses. The operation of all electrical equipment, from headlights to the on-board computer, depends on their serviceability. However, find the correct fuse in block J11 not so simple: the circuit differs from previous generations, and the manual often lacks details.

In this article we will look at exact locations of fuse boxes (in the cabin and under the hood), we will decipher the purpose of each relay, show how to correctly diagnose a fault with a multimeter, and warn against typical mistakes when replacing. We will pay special attention fuse F37 (10A) - it is responsible for the operation of the rear view camera and often blows out when there is a short circuit in the connector.

Where are the fuse boxes located in Qashqai J11

B Nissan Qashqai J11 provided three main fuse boxes:

  • 🚗 Inside — under the instrument panel on the driver’s side (behind the decorative cover). Here are the fuses for the internal equipment: audio system, cigarette lighter, heated seats.
  • 🔧 In the engine compartment — next to the battery (black plastic box with a lid). Responsible for the starter, generator, ignition system.
  • 🔌 Additional relay block — behind the glove compartment (only in versions with Bose And Around View Monitor). Manages multimedia and cameras.

To access the interior unit, pull the latch at the bottom of the panel (near the brake pedal). The cover can be removed without tools. In the engine compartment, first disconnect negative battery terminal - this is a must for safety!

Fuse diagram and decoding Qashqai J11 (2014–2021)

Below is complete fuse table for the cabin unit (the most popular). Please note: numbers may vary depending on the year of manufacture and equipment (for example, in Qashqai J11 2017 with ProPilot added fuses F45 and F46).

Number Amps Purpose Notes
F1 10A Audio system, navigation Burns out when there is a short circuit in the speakers
F10 15A Cigarette lighter, 12V socket A common reason is connecting powerful devices (for example, a compressor)
F22 7.5A Parking sensors Check sensor connectors for corrosion
F37 10A Rear view camera Often fails in wet weather (moisture gets into the connector)
F40 15A Heated seats Check when heating is not working on one side

The following fuses are relevant for the engine compartment:

  • ⚡ F1 (30A) — radiator cooling fan. When it burns out, the engine overheats.
  • ⚡ F5 (10A) — engine control unit (ECU). Critical for startup.
  • ⚡ F12 (15A) — fuel pump. If the fuse is blown, the car will not start.
How to check a fuse without a multimeter?

If you don’t have a tester at hand, you can visually inspect the fuse using light: the blown thread will be broken. You can also use the “replacement method” - temporarily install a known-good fuse with the same rating from another slot (for example, from the cigarette lighter).

How to check the fuse in Qashqai J11: step by step instructions

For diagnosis you will need multimeter (or at least a 12V control lamp). Follow the algorithm:

  1. Turn off the ignition and remove the fuse box cover.
  2. Set the multimeter to mode calls (or resistance measurements).
  3. Touch the probes to fuse contacts (without touching the body!). The working one will show 0 ohm, burnt - 1 (gap).
  4. If the fuse is good, check tension on his legs (must be 12V on one side and 0V on the other with the ignition on).

Ignition turned off|Unit cover removed|Multimeter in dial mode|Both fuse contacts checked|Voltage measured (if necessary)-->

If the fuse is blown, don't rush to replace it - first find the cause of the short circuit! Common culprits:

  • 💡 Oxidized contacts in the blocks (especially in the headlight and tail light connectors).
  • 🔌 Damaged wire insulation under the hood (rubbed against the body).
  • 📱 Non-standard devicesconnected to the cigarette lighter (DVRs, chargers).
💡

If the fuse blows again after replacement, disconnect the circuit it protects and check for a short circuit using a multimeter in resistance mode (should be more than 1 ohm).

Typical mistakes when replacing fuses

Even experienced car owners make mistakes that lead to repeated breakdowns or even fire. Here's what not to do:

⚠️ Attention! Never use fuses with overvalued (for example, 20A instead of 10A). This may cause the wiring to melt and cause a fire. B Qashqai J11 chains are especially critical ECU And fuel pump — their protection is designed to strict parameters.

Other common mistakes:

  • 🔧 Using "bugs" (homemade wire jumpers). This is a gross violation of safety regulations.
  • 🔍 Replacement without diagnostics. If the new fuse blows immediately, the problem is in the circuit, not him.
  • 💦 Working with wet hands or in the rain. Moisture can cause a short circuit in the block.
  • 🔄 Confusion in numbers. The headlight fuse (F25) and the wiper fuse (F18) have the same rating (15A), but are not interchangeable!

Case Study: Owners Qashqai J11 with LED optics They often put a 20A fuse in slot F25 (lighting) instead of the standard 15A, citing “brighter light.” The result is melting of the headlight connectors and replacement of all wiring.

💡

If the fuse blows immediately after replacement, the circuit must be checked from end to beginning: first the consumer (for example, a headlight), then the wires, and only then the control unit.

Which fuse is responsible for the cigarette lighter and why does it blow out?

B Nissan Qashqai J11 The fuse is responsible for the cigarette lighter and 12V socket F10 (15A) in the salon block. It burns out more often than others for three reasons:

  1. Connecting powerful devices (compressors, refrigerators) without adapter. The socket's rated current is 10A, but many devices consume up to 15A.
  2. Short circuit in the connector due to coins or metal debris.
  3. Oxidation of contacts in the outlet itself (especially if chargers are often connected/disconnected).

If fuse F10 is blown, follow these steps:

  1. Unplug all devices.
  2. Remove the fuse and check it with a multimeter.
  3. Inspect the cigarette lighter connector for foreign objects.
  4. If the fuse is good, but the socket does not work, check relay K9 in the cabin unit (it controls the power supply).
⚠️ Attention! Available with 360 degree camera The 12V socket in the trunk is also protected by fuse F10. If, after replacing the fuse, the socket in the passenger compartment works, but not in the trunk, check wiring under the casing (often frays at the bend).

Where to buy fuses for Qashqai J11: original vs analogues

Original fuses Nissan supplied with the car (in the glove compartment or under the unit cover). Their articles:

  • 🔧 28510-4M000 — a set of mini fuses (10 pcs., different ratings).
  • 🔧 28510-AL600 — a set of maxi fuses (for the engine compartment).

If originals are not available, you can use analogues from trusted brands:

Brand Series Notes
Bosch F 000 000 003 High quality, suitable for ECU circuits
HELLA 8FL 003 138-831 Corrosion resistant, recommended for the engine compartment
Littlefuse LMF Optimal in price/quality, available in any auto store

Avoid cheap fuses without markings - they often have increased resistance, which leads to false positives. For example, a 10A fuse may actually only "hold" 8A, causing it to blow under normal load.

Where to buy:

  • 🛒 Official dealers Nissan - original fuses, but expensive.
  • 🛒 Auto stores (AutoSpetsCenter, existential) - a wide selection of analogues.
  • 🛒 Internet (AliExpress, Wildberries) - cheaper, but there is a risk of running into a fake.

FAQ: Frequently asked questions about fuses Qashqai J11

Is it possible to install a fuse of a higher rating if the standard one often blows?

No! This will lead to melting of the wiring. If the fuse blows frequently, look for the cause in the circuit: check consumers (for example, lamps in headlights), wires for short circuits and connectors for oxidation. B Qashqai J11 chains are especially vulnerable heated windshield (F30) and stove fan (F20).

Which fuse controls the starter?

Responsible for the starter in the engine compartment fuse F2 (50A) And relay K1. If you hear clicks when you turn the key, but the starter does not turn, also check negative wire from the battery to the body - it often oxidizes.

Why did the image not appear after replacing fuse F37 (rear view camera)?

The reasons may be as follows:

  1. Defective camera connector (moisture has entered or the contacts have oxidized).
  2. Burnt out relay K12 in the cabin unit (controls the power supply of the camera).
  3. Damaged wire from the camera to the control unit (often frayed in the trunk).

Also check your media settings: sometimes after changing the fuse the camera turns off in the menu (Settings → Camera → Enable).

Where is the fuse for the radio?

B Qashqai J11 responsible for the audio system fuse F1 (10A) in the salon block. If after replacing it the radio does not turn on, check:

  • 🔌 ISO connector on the back of the radio (often oxidizes).
  • 🔋 Fuse on the radio itself (if it is abnormal).
  • 📶 Antenna amplifier (in the bumper) - if it malfunctions, the radio may not turn on.
How to reset the "Check Engine" error if it appeared after replacing the fuse?

Error Check Engine after replacing the fuse (e.g. F5 for ECU) is reset like this:

  1. Disable negative battery terminal for 10 minutes.
  2. Reconnect and start the engine.
  3. If the error persists, use a diagnostic scanner (for example, ELM327) to reset. B Qashqai J11 power supply errors ECU have codes P0600–P0606.
