Fuse box Nissan Qashqai J11 (2013–2021) is a key element of the electrical system, on which the operation of the entire vehicle depends: from headlights and window lifts to the engine control unit. A faulty fuse can lead to the failure of critical systems, and replacing it - a seemingly simple procedure - is fraught with pitfalls if you do not know the nuances of its location and circuit.

In this article you will find detailed fuse box diagrams for all modifications Qashqai J11 (including restyling 2017), decoding of each element, as well as step-by-step instructions for diagnosis and replacement. We will analyze the typical mistakes of owners that lead to a short circuit, and explain how to avoid damage to electronics when working with the unit. Particular attention is paid fuse F37 (10A), responsible for the start-stop system - its blown is often mistaken for a battery failure.

Where is the fuse box located on the Nissan Qashqai J11

B Nissan Qashqai J11 provided two main fuse boxes:

  • 🔧 Main unit in the cabin — located to the left of the steering column, under the decorative cover. To gain access, pull the cover towards you (it is secured with latches).
  • ⚡ Additional block under the hood — located next to the battery, in a plastic box with the inscription FUSE BOX. The lid is secured with two latches.

On vehicles with diesel engine (For example, 1.5 dCi or 1.6 dCi) there may be an additional fuse in the engine compartment F101 (30A), responsible for the injection system. On petrol versions (1.2 DIG-T, 2.0 MR20DD) it is not present - this is important to take into account when diagnosing.

Also in Qashqai J11 There is third relay blocklocated behind the glove compartment. It is responsible for the operation of the cooling fans and fuel pump. Access to it is difficult - you need to remove the glove compartment (4 bolts T20).

Diagram and decoding of the cabin unit fuses

Cabin fuse box Nissan Qashqai J11 contains 40 fuses (depending on the configuration). Below is a table with a breakdown of the most popular elements. The complete diagram for your modification can be found in Operating manual (section 8-30).

Number Ampere Purpose Notes
F3 10A ABS/VDC system Lights up when burned out ABS And VDC OFF on the dashboard
F7 10A Body Control Module (BCM) Responsible for central locking, power windows, interior lighting
F15 15A Audio system, navigation When replacing, check the connector ANT to the cliff
F37 10A Start-stop system Often burns out when the battery is discharged or the generator is faulty
F40 20A Cigarette lighter, 12V socket Burns out when connecting powerful devices (for example, a compressor)

Please note: on vehicles with package Tekna or N-Connecta The block contains additional fuses F22 (7.5A) for 360° camera and F28 (10A) for the system ProPilot. Their absence in basic configurations (Visia, Acenta) is the norm.

⚠️ Attention: fuse F37 (10A) often confused with F38 (15A), which is responsible for parking sensors. When replacing, check the markings - installing a fuse of a larger rating will damage the start-stop system control unit (I-KEY).

Engine compartment fuse diagram

Engine compartment block Nissan Qashqai J11 contains high current fuses (from 20A to 120A) and relays. Its peculiarity is the presence fuse links (fusible links), which are similar in appearance to fuses, but are replaced entirely, and not just the fusible part.

Below are the key elements of the block:

  • 🔥 F1 (100A) — Main fuse for the battery charging circuit. If there is a burnout, the car will not start, the dashboard lights up Battery.
  • ⚡ F5 (30A) — Electric cooling fans. If it burns out, the engine overheats, but the temperature sensor may not work.
  • 🚗 F12 (15A) — Engine control unit (ECU). If there is a malfunction, an error appears P0600.
  • 💡 F18 (10A) — Headlights (low beam). It often burns out when installing LED lamps without a voltage corrector.

B diesel versions added:

  • 🛢️ F101 (30A) — High pressure fuel pump (HPFP).
  • 🔥 F103 (40A) — Glow plugs. If the engine burns out, it is difficult to start when cold.
What to do if fuse F1 (100A) is blown?

If the main fuse is blown F1 (100A), this indicates a short circuit in the charging circuit. Don't replace it right away! First check:

1. Condition of the battery terminals (oxidation, poor contact).

2. The integrity of the wires from the generator to the battery (they often rub against the body).

3. Generator operation (voltage at the terminals should be 13.8–14.5V when the engine is running).

Replacing the fuse without eliminating the cause will lead to re-blowout and possible wiring fire.

How to check and replace a fuse: step-by-step instructions

Before replacing the fuse necessarily:

  1. Turn off the ignition and remove the key from the lock.
  2. Disconnect the negative terminal of the battery (especially when working with the engine compartment).
  3. Use plastic tweezers from the fuse kit - metal tools can short the contacts.

To check the fuse:

  1. Remove the fuse from its socket.
  2. Inspect the fusible link - if it is broken, the fuse is faulty.
  3. Ring the multimeter in mode calls (should beep when both contacts are touched).

When replacing:

  • 🔧 Install a fuse same denomination. For example, instead of 10A can't bet 15A - this will lead to damage to the protected circuit.
  • 🔍 If the new fuse immediately blows, there is short circuit - Wiring diagnostics required.

⚠️ Attention: On Qashqai J11 with the system ProPilot fuse F28 (10A) protects the camera control unit. When replacing it do not touch contacts with bare hands - Static electricity can damage sensitive electronics. Use an antistatic wrist strap or at least touch a metal part of the body before working.

Typical faults and their causes

Owners Nissan Qashqai J11 Frequently encounter the following problems related to fuses:

  • 🔋 Frequent burnout F37 (10A) - caused by a malfunction of the start-stop system or a discharged battery. Solution: Check the battery voltage (must be at least 12.6V with the engine off) and the state of the generator.
  • 💡 Burnout F18 (10A) when the headlights are turned on — occurs when installing LED lamps without a voltage stabilizer. Solution: Return halogen bulbs or install a load relay.
  • 🚪 Power windows don't work - the fuse is at fault F7 (10A) or relay R17. Also check the door control unit (BCM).
  • 🔊 Audio system doesn't work - fuse F15 (15A) or a break in the antenna connector (ANT).

The problem with fuse F1 (100A) in the engine compartment. Burnout is often associated with:

  • Short circuit in the generator circuit (check the diode bridge).
  • Starter malfunction (especially on vehicles with MR20DD after 2017).
  • Poor contact at the battery terminals (oxidation or loose tightening).
💡

If the fuse blows again after replacement, do not rush to install a new one! Use probe with light bulb (or multimeter in mode 200mA) to find a short circuit. Connect the probe instead of the fuse - if the light comes on, there is a short circuit in the circuit. Disconnect consumers one by one (for example, headlights, fans) to localize the problem.

How to avoid damage to electronics when working with fuses

Incorrect replacement of fuses on Nissan Qashqai J11 can lead to serious damage, especially in cars with advanced systems (ProPilot, Around View Monitor). Follow these rules:

  • 🔌 Always disconnect the battery when working with the engine compartment. Even the ignition is turned off does not guarantee the absence of voltage in the circuits.
  • 🧲 Do not use metal tools to remove fuses - risk of short circuit.
  • 📋 Keep a log of replacements: Record the date and reason for replacing the fuse. This will help identify systemic problems (for example, regular burnout F40 may indicate a faulty 12V socket).
  • 🔍 Check the chain after replacement: if the fuse blows again, do not replace it - look for the cause (short circuit, faulty consumer).

On vehicles with system NissanConnect (multimedia complex) special care should be taken when working with a fuse F15 (15A). When replacing it:

  1. Wait until the screen turns off completely (about 30 seconds after turning off the ignition).
  2. Do not press the buttons on the panel during replacement - this may cause the firmware to fail.
  3. After replacement, reset the system: hold the button POWER 10 seconds.
⚠️ Attention: On Qashqai J11 with CVT JF016E fuse F12 (15A) in the engine compartment protects the transmission control unit (TCM). When replacing it do not start the engine for 1 minute — this time is needed to initialize the system. Ignoring this rule may result in jerking when changing gears.

Owner Frequently Asked Questions (FAQ)

Why does the start-stop system not work after replacing fuse F37 (10A)?

If the fuse is intact but the start-stop system does not activate, check:

  1. Battery voltage (must be at least 12.8V).
  2. Tilt sensor status (Inclination Sensor) - when there is a malfunction, the dashboard lights up Start-stop service.
  3. Connector on the control unit I-KEY (located under the steering wheel). Contacts often oxidize.

If the problem persists, diagnostics with a scanner is required (for example, Launch X431) for errors U1000 or B2604.

Is it possible to replace a fuse with a higher rating if it blows frequently?

Absolutely not! Installing a fuse of a higher rating (for example, 15A instead of 10A) will lead to:

  • Overheating and melting of wiring.
  • Damage to the control unit (for example, BCM or ECU).
  • Fire in the passenger compartment (especially dangerous for high-load circuits, such as the cigarette lighter).

If the fuse blows frequently, look for the cause: a short circuit, a faulty consumer or poor contact.

Where can I find a fuse diagram for my Qashqai J11?

Fuse patterns vary depending on:

  • Year of manufacture (before/after restyling 2017).
  • Engine type (gasoline/diesel).
  • Equipment (Visia, Acenta, Tekna etc.).

The exact diagram can be found:

  1. B Operating manual (section 8-30).
  2. On the sticker on the inside of the fuse box cover.

What should I do if, after replacing the fuse, the device still does not work?

If the fuse is intact, but the consumer (for example, headlights or window regulator) does not work, check:

  • 🔌 Relay — in the cabin unit next to the fuses there are relays (for example, R17 for window regulators). Test them by swapping them with a known working one (for example, a fan relay).
  • 🔌 Wiring — inspect the connectors for oxidation or breakage. For example, for headlights, check the connector E20 under the hood.
  • 📶 Control unit — if several devices do not work at the same time (for example, power windows and central locking), the problem may be BCM (body control unit).

For diagnostics, use a multimeter in mode calls or contact an electrician with a scanner (for example, to check CAN buses).

💡

Before replacing a fuse, always check the reason for his burnout. Repeated blowing of the new fuse indicates a short circuit or consumer malfunction. Ignoring this problem may lead to a wiring fire or failure of the control unit.
