Nissan Qashqai: fuses and relays - location, diagram and replacement

Fuses and relays in Nissan Qashqai is “insurance” for the vehicle’s electrical system. A blown fuse can immobilize your car or disable critical functions, from headlights to the ignition system. But how can you find the right element among dozens of parts in a block if you don’t have a manual at hand? In this article we will analyze fuse box location for Qashqai J11 (2006–2013) and J12 (2014–2021), we will decipher the diagrams, explain how to diagnose faults and replace elements without errors.

Feature Qashqai — division of fuses into several blocks: the main one in the cabin, an additional one under the hood and separate relays for powerful consumers (for example, a cooling fan). However, the diagram may differ depending on the year of manufacture and configuration. For example, in cars with xenon headlights or Start/Stop system additional relays are added. We have collected current data for all modifications, including restyled versions.

Where are the fuse boxes in the Nissan Qashqai?

B Nissan Qashqai fuses and relays are distributed over three main zones. Their location is unified for most generations, but there are nuances:

• 🔧 Main unit in the cabin - under the instrument panel on the driver's side. To gain access, you need to open the door and snap off the plastic cover (on J12 it is attached with latches, on J11 - on screws).
• 🚗 Block under the hood — next to the battery, in a plastic box with a black lid. High power fuses are located here (for example, for a generator circuit).
• ⚡ Additional relays - may be located behind the glove compartment (on some versions J11) or under the center console (on J12 with the system Intelligent Key).

On Qashqai J12 after 2017, a separate relay appeared in the unit under the hood for preheating systems (if installed). B J11 Until 2010, the cooling fan relay could be located separately from the main unit - it is often confused with the starter relay.

Fuse diagram for Nissan Qashqai J11 (2006–2013)

In the first generation Qashqai The fuse diagram is simpler than in J12, but there are pitfalls. For example, fuse F30 (10A) is responsible for engine control unit (ECU) - if it burns out, the car may not start. Below is a table with a breakdown of the main unit in the cabin:

In the block under the hood J11 pay special attention to the fuse F1 (100A) — it protects the generator circuit. Its burnout is often accompanied loss of battery charge and dim headlights. If this happens, check the voltage regulator relay on the generator.

⚠️ Attention: On Qashqai J11 with diesel engine 1.5 dCi fuse F25 (15A) responsible for the work fuel pump. Replacing it without diagnosing the cause of the burnout can lead to repeated failure.

In the second generation Qashqai The electrical circuit has become more complex due to the addition of new systems: 360° cameras, adaptive cruise control And keyless entry. The main unit in the cabin now contains 40 fuses (versus 30 V J11). Below are the key elements:

• 🔋 F5 (7.5A) — immobilizer and system Nissan Intelligent Key. If it burns out, the car does not recognize the key.
• 📹 F15 (10A) — rear view camera and parking sensors. If the fuse is blown, the media screen will show a black square.
• 🚨 F28 (10A) — alarm and central locking. It often fails due to a short circuit in the door actuators.
• 💡 F35 (15A) — fog lights. On restyled versions (after 2017), a relay was added for LED-PTL.

In the block under the hood J12 fuse appeared F1 (120A) for main power relay. Replacing it requires disconnecting the battery and removing the terminal for 10 minutes (to reset errors in BCM). If the fuse blows again after replacement, check wiring on the generator And body weight near the battery.

Disconnect the battery (negative terminal first)

Check the fuse visually (the jumper must be intact)

Measure the voltage at the contacts with a multimeter (should be 12V)

Check the circuit for a short circuit (continuity tester)

Install a fuse of the same rating -->

How to check and replace a fuse

Replacing the fuse in Nissan Qashqai It seems like a simple procedure, but there are risks. For example, installing a fuse higher denomination may cause a fire in the wiring. Follow the algorithm:

1. Turn off the ignition and remove negative terminal from the battery (required!).
2. Find the faulty fuse according to the diagram (see section above) and remove it plastic tweezers (metal may damage the contacts).
3. Check the integrity of the jumper: if it is burned out, a break or blackening will be visible on the body.
4. Install a new fuse same denomination. The use of “bugs” (wire jumpers) is prohibited!
5. Connect the battery and check the circuit operation. If the fuse has blown again, look for short circuit.

To check the circuit for a short circuit, use a multimeter in continuity mode:

1. Отключите предохранитель.
2. Подключите один щуп к контакту предохранителя со стороны цепи, второй — к массе.
3. Если раздаётся звуковой сигнал — в цепи КЗ.

⚠️ Attention: On Qashqai with the system Start/Stop (For example, J12 1.6 DIG-T) after replacing fuses it may be necessary reset adaptations through a diagnostic scanner. Otherwise, the system will not work correctly.

Reasons for frequent blown fuses

If the fuses are in Nissan Qashqai lights up regularly, this is a signal of a serious malfunction. Let's look at typical reasons:

• ⚡ Short circuit (SC) - the most common reason. Most often occurs in circuits:
  • Wiring of power windows (grinding in doors).
  • Cigarette lighter circuit (when connecting non-standard devices).
  • Rear light wiring (contact oxidation).
• 🔌 Poor contact - oxidized or loose terminals create increased resistance, which leads to heating and blown fuse.
• 🔋 Power surges - a faulty generator or voltage regulator can produce up to 16–18V, which is detrimental to electronics.
• 🚗 Non-standard equipment - radio tape recorders, video recorders or LED lamps connected without a relay often cause overload.

On Qashqai J11 with a mileage of more than 150 thousand km, a problem with relay block under the hood: Moisture penetrates through cracks in the housing, causing corrosion of the contacts. This leads to false tripping of fuses F1–F5. The solution is to seal the block with silicone sealant or replace it with a new one.

Relay in Nissan Qashqai: location and diagnostics

Relay in Qashqai are responsible for turning on powerful consumers: starter, cooling fan, fuel pump. Their malfunction manifests itself in different ways:

• 🔑 The starter does not turn - check the relay K1 in the block under the hood (on J11 it is black).
• 🌬️ Cooling fan does not work - the relay is at fault K7 or fuse F3 (30A).
• ⛽ Engine won't start - fuel pump relay K5 (located under the rear seat on J12).

To check a relay, just swap it with a known good one (for example, a horn relay K3). If the device works after replacement, the relay is faulty. For accurate diagnostics, use a multimeter:

1. Установите реле в положение "Вкл." (подключите 12V к контактам 85 и 86).
2. Проверьте сопротивление между контактами 30 и 87 — должно быть ~0 Ом.
3. Если сопротивление бесконечно — реле сгорело.

On Qashqai J12 with hybrid system (For example, 1.3 DIG-T) relay added K10 for management lithium-ion battery. Replacing it requires a special tool and a reset via CONSULT-III+.
