Nissan Qashqai J10 (2007-2013): fuse box - location, diagram and decoding

Nissan Qashqai first generation (J10, 2007–2013) remains a popular crossover due to its reliability and maintainability. However, even such a proven car eventually develops electrical problems—the headlights, power windows, or multimedia system refuse to work. In 80% of cases it is to blame fuse box, where the contact burns out or oxidizes.

In this article you will find complete diagram of the fuse and relay box for Qashqai J10 with decoding of each element, including nuances for different trim levels (with diesel engines K9K and gasoline MR20DE/HR16DE). We will also analyze typical symptoms of malfunctions and show how to correctly diagnose and replace fuses without risking burning out the car's electronics.

Where is the fuse box located in the Nissan Qashqai J10

B Qashqai J10 There are two main fuse blocks:

• 🔧 Main unit — located 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 (it is secured with two latches).
• ⚡ Additional relay block — located in the engine compartment, next to the battery (on some versions it is covered with a black plastic cover).

On vehicles with K9K diesel engine (1.5 dCi) there may be a third, small fuse block - it is responsible for the injection system Common Rail and is located next to the engine control unit (ECU). It is easily identified by its yellow body color.

Important: on restyled versions Qashqai J10 (2010–2013) the location of the blocks has not changed, but some fuse numbers may differ. For example, the cigarette lighter fuse on a dorestayl - F37 (15A), and on the restyling - F42 (20A).

Diagram and decoding of the cabin unit fuses

Main fuse box in the passenger compartment Nissan Qashqai J10 contains 45 fuses (depending on the configuration). Below is a table with a breakdown of the most popular elements:

Number	Ampere	Purpose	Symptoms of a problem
F1	10A	ABS control unit, wheel speed sensors	ABS light is on, anti-lock braking system is not working
F10	10A	Dashboard lighting, brightness control	The speedometer backlight does not work, the indicators are dim
F20	15A	Window lifters (driver's door)	The driver's window doesn't work, but the passenger windows work.
F37/F42	15A/20A	Cigarette lighter, 12V socket	The cigarette lighter does not work, devices do not charge via USB
F40	10A	Audio system, navigation, Bluetooth	The radio does not turn on, there is no sound, Hands-Free does not work

A complete diagram with the numbers of all fuses can be found on the back of the block cover (factory markings are applied there). If the inscriptions are erased, download original instruction manual for your configuration.

⚠️ Attention: On versions with xenon headlights fuse F15 (10A) is responsible for the ignition unit. If this fuse blows, the headlights will flicker or not turn on at all. Do not replace it with a fuse of a higher rating - this may burn the light control unit!

Relay in Nissan Qashqai J10: purpose and typical problems

In the salon block Qashqai J10 installed 12 relaysthat control highly loaded circuits: starter, cooling fan, fuel pump, etc. Below is a list of the most important relays and symptoms of their failure:

• 🔋 R1 (Starter relay) — if it doesn’t click when you turn the key, check this relay. Contacts often oxidize.
• 💨 R5 (Cooling fan relay) — if it breaks down, the engine overheats, the fan does not turn on even at high temperatures.
• ⛽ R7 (Fuel pump relay) - if the car does not start, but the starter turns, check this relay (and fuse F2 (15A)).
• 🔦 R10 (Low beam relay) — if there is a malfunction, the headlights work chaotically or do not turn on at all.

Relay in Qashqai J10 standard - they can be replaced with similar ones from other models Nissan (for example, from X-Trail T31 or Note E11). The main thing is that the ratings and type of contacts match.

How to check and replace a fuse or relay

For diagnostics and replacement of fuses in Nissan Qashqai J10 you will need:

• 🔧 Tweezers (usually included with the machine, attached to the unit cover).
• 🔦 Flashlight (to inspect contacts).
• 📊 Multimeter (to check voltage).
• 🔄 Spare fuses (set with ratings 5A, 10A, 15A, 20A, 25A).

Step by step instructions:

1. Turn off the ignition and remove the negative terminal from the battery (required!).
2. Open the fuse box cover (it is secured with two latches).
3. Find the faulty fuse according to the diagram (a blown fuse has a broken thread inside).
4. Use tweezers to remove the fuse and check it with a multimeter in the “continuity” mode.
5. Install a new fuse same denomination (no more!).
6. Connect the battery and check the circuit operation.

Disconnect the negative terminal of the battery|

Check the new fuse for proper rating|

Inspect the contacts in the socket for oxidation|

Make sure that the problem is not a short circuit (otherwise the new fuse will burn out immediately) -->

If the new fuse blows immediately, it means there is some fault in the circuit. short circuit. In this case, you need to check the wiring in the area from the unit to the device (for example, to the cigarette lighter or headlight). Often the problem lies in frayed wires under the dashboard or in doorways.

Typical faults and their causes

Owners Nissan Qashqai J10 Often encounter the following problems related to the fuse box:

• 🚗 Power windows don't work - usually the fuse is to blame F20 (15A) or relay R3. Also check the buttons on the driver's door (contacts often oxidize).
• 🔊 The radio does not turn on - fuse F40 (10A) or a break in the wiring harness behind the dashboard.
• 💡 Headlights don't come on - check the fuses F14/F15 (10A) and relay R10. On diesel versions, the light control unit may also be faulty (BCM).
• 🔌 Cigarette lighter doesn't work - fuse F37/F42 or oxidation of contacts in the socket. Often the problem occurs after using powerful devices (for example, a compressor).

Particular attention should be paid oxidation of contacts in the fuse block. Due to moisture (for example, after washing or in rainy weather), the contacts become covered with a green coating, which leads to poor contact. In this case, cleaning will help WD-40 or a special contact spray.

⚠️ Attention: If the interior smells of burnt plastic and the fuses are constantly burning, this is a sign turn-to-turn short circuit in the wiring or control unit malfunction. In this case, it is not recommended to operate the vehicle until the cause is eliminated!

What should I do if the fuse is constantly on?

If the new fuse blows immediately after installation, there is a short circuit in the circuit. Algorithm of actions:

1. Disconnect all devices connected to this circuit (for example, disconnect the cigarette lighter or headlights).

2. Install a new fuse - if it does not blow, the problem is in one of the devices.

3. Connect devices one by one to find the culprit.

4. If the fuse burns even without a load, look for a short circuit in the wiring (frayed wires, damaged connectors).

Where to buy fuses and relays for Qashqai J10

Fuses and relays for Nissan Qashqai J10 are sold in any auto store, but it is better to choose original or proven analogues:

• 🏬 Original fuses - article number 28501-JM00A (set of 10 pieces of different denominations). Cost: ~300–500 rub.
• 🔧 Analogues — brands Bosch, Hella or Valeo (quality is not inferior to the original, but 20–30% cheaper).
• 🛒 Relay — original 25230-3M200 (for starter) or 25230-AL50A (universal). Cost: 400–800 rub.

When purchasing, pay attention to denomination (it is indicated on the fuse housing) and contact type (relays have “legs” of different shapes). You can find cheap sets on AliExpress, but their quality often leaves much to be desired - it’s better to overpay for reliability.

If you live in a cold climate, it is recommended to keep a spare set of fuses and relays in the glove compartment. In winter, due to temperature changes, the plastic becomes brittle and fuses can crack even without a short circuit.

Frequently asked questions about the Qashqai J10 fuse box

Is it possible to install a larger fuse if it is constantly on?

No! The fuse is rated for a certain current, and if it is lit, there is a problem in the circuit (short circuit or overload). Installing a fuse with a larger rating may lead to melting of the wiring or failure of the device (for example, the control unit).

How can you tell if a relay has burned out and not a fuse?

A relay is an electromechanical device that clicks when activated. If you don't hear a click when you turn on a circuit (such as headlights), the relay is likely bad. You can also swap it with a known working one (for example, the fan relay and starter relay are often interchangeable).

Why does the cigarette lighter still not work after replacing the fuse?

Possible reasons:

1. The contacts in the cigarette lighter socket have oxidized (the socket needs to be cleaned or replaced).
2. The fuse in the circuit has blown ACC (check F3 or F4 depending on the year).
3. The problem is in the cigarette lighter itself (the coil has burned out or the contact has come loose).

Where can I find a fuse box diagram for my configuration?

The diagram is printed on the back of the block cover. If it's erased, download it official guide for your year of manufacture or find the sticker in the glove compartment (on some versions it is duplicated there). There are also diagrams on the forums Qashqai Club.

Is it possible to repair the fuse box yourself if the contacts have melted?

If only the contacts in the socket are melted, they can be carefully cleaned with a file or soldering iron (if you have experience). If the block itself has melted, it needs to be replaced entirely, since it is almost impossible to restore the printed tracks at home.
