Nissan Qashqai J10: fuse diagram with explanations and typical errors

Owners Nissan Qashqai first generation (J10, 2007–2013) sooner or later face the need to check or replace fuses. A car's electrical circuits are protected by dozens of fusible elements, and without an exact diagram of their location, even a simple replacement of a light bulb can turn into an hour-long search for the “same” fuse. In this article we will look at all Qashqai J10 fuse boxes - from the interior to the engine compartment, with a breakdown of each element and practical diagnostic tips.

Feature J10 The point is that the fuse diagram may vary slightly depending on the configuration and year of manufacture. For example, in cars with 2.0 MR20DE or diesel 1.5 dCi added relays for the fuel pump and injection system. We took these nuances into account and provided universal data that is relevant for most versions. If your Qashqai equipped with additional options (for example, xenon or heated seats), at the end of the article you will find a separate section with amendments.

Where are the fuse boxes located in the Nissan Qashqai J10

B Qashqai J10 fuses and relays are distributed over three main blocks:

• 🔧 Salon block — located to the left of the steering column, behind the plastic cover. Responsible for lighting, audio system, power windows and most of the “comfort” functions.
• 🚗 Engine compartment block — next to the battery, under the black plastic cover. High power fuses are concentrated here (generator, fans, ABS).
• 🔋 Additional relay block — in some trim levels it is installed behind the glove compartment or under the center console. Controls the climate control and ignition system.

To gain access to the interior unit, just pull the cover towards you (it is secured with two latches). The engine compartment requires care: before removing the cover Be sure to disconnect the negative terminal of the batteryto avoid a short circuit if the tool accidentally touches the “positive” contacts.

Interior fuse box: diagram and decoding

Salon block Qashqai J10 contains up to 40 fuses and relays, responsible for most consumers. Below is a table with numbers, denominations and purpose of each element (relevant for most configurations, including 1.6 HR16DE And 2.0 MR20DE).

Fuse no.	Denomination (A)	Purpose	Notes
1	10	Body Control Module (BCM)	When burned out, the power windows and central locking fail
7	15	Cigarette lighter	Often fails when using powerful devices (for example, compressors)
12	10	Audio system, navigation	If the radio does not turn on, also check the relay R12
20	15	Low beam (left headlight)	When replacing a lamp, always check this fuse
30	20	Heater fan	If the stove blows weakly, not only the fuse, but also the resistor may be to blame

Please note: in vehicles with xenon headlights low beam fuse (№20) can be replaced by 20A instead of standard 15A. Also in some versions the fuse No. 25 (10A) is responsible for rain and light sensor - If the automatic headlights do not work correctly, check it first.

⚠️ Attention: Never replace fuses with higher rated ones! For example, instead of 10A can't bet 15A - this may lead to melting of the wiring or fire. If a fuse keeps blowing, look for the cause in a short circuit, not in its rating.

Engine compartment: high-power fuses and relays

Engine compartment block Qashqai J10 contains fuses and relays responsible for critical systems: battery charging, engine operation, ABS and cooling. Here the element values reach 80–120A, so special care is required when replacing.

Key elements of the block:

• ⚡ F1 (100A) — Generator main fuse. When the battery burns out, the battery does not charge, the indicator lights up battery icon.
• ❄️ F5 (30A) — Cooling fan fuse. If it burns out, the engine will overheat.
• 🔄 R3 — Fuel pump relay. If it fails, the engine will not start (the pump will not be heard when the ignition is turned on).
• 🚨 F10 (10A) — ABS system fuse. If it burns out, it will light up on the dashboard orange ABS badge, but the brakes will remain working.

To check the fuse F1 (100A), you will need a multimeter in dialing mode. Do not try to visually determine its serviceability - such fuses often “ring” even with external integrity. If the generator does not charge, also check diode bridge And voltage regulator.

Common fuse problems and how to avoid them

Owners Qashqai J10 Often faced with repeated blowing of fuses after replacement. This signals more serious electrical problems. Let's look at the most common cases:

1. Cigarette lighter (fuse No. 7, 15A) — burns out due to the use of powerful devices (for example, car vacuum cleaners or compressors). Solution: Use a power strip with a separate fuse or connect devices directly to the battery.
2. Low beam (fuses No. 20 and No. 21) — often fail when installing LED lamps. LED bulbs use less current but can cause voltage surges. Solution: install load resistors or go back to halogen bulbs.
3. Heater fan (fuse No. 30, 20A) — burns out when the fan motor brushes wear out. Solution: replace the heater motor or clean it of dust.

If the fuse blows immediately after replacement, do not try to place an element of a higher value - this may cause a fire! Instead:

Check the circuit for short circuit with a multimeter|Inspect the wires for melting or damaged insulation|Disconnect all consumers connected to this fuse|Check the operation of the relay associated with this circuit-->

For example, if the fuse is constantly on No. 10 (10A) (responsible for window lifters), the problem may lie in a jammed motor or a damaged wiring harness in the door. In this case, disassemble the door trim and check the integrity of the wiring in the corrugation between the body and the door.

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Qashqai J10 - a simple procedure, but requiring accuracy. Follow this algorithm to avoid errors:

1. Turn off the ignition and remove the key from the lock. For the engine compartment unit, also remove the negative terminal from the battery.
2. Find the faulty fuse according to the scheme (see sections above). In the interior unit, the numbers are indicated on the inside of the lid.
3. Remove the fuse with special plastic tweezers (usually attached to the block cover). Never use metal tools!
4. Check the fuse visually or with a multimeter. A burnt thread or a melted body is a sign of a malfunction.
5. Install a new fuse the same denomination. If you don’t have the original one at hand, you can temporarily use a fuse from another circuit (for example, from a cigarette lighter), but only if their ratings match.

After replacement, turn on the ignition and check the operation of the circuit. If the fuse blows again, the problem lies deeper (see the section on common problems).

⚠️ Attention: B Qashqai J10 with the system Start/Stop (restyling versions) replacing fuses with the ignition on may lead to resetting the on-board computer settings. Always turn off the ignition before working on electrical equipment!

Additional fuses included with options

If your Qashqai J10 equipped with additional options (for example, xenon, heated seats or rear view camera), extra fuses will appear in the electrical circuit. Their location depends on the year of manufacture:

• 💡 Xenon headlights: fuse 40A in the engine compartment (designated as F-Xenon). Also added relay R-Xenon for the ignition unit.
• 🔥 Heated seats: fuse 20A in the cabin block (usually №35). If there is a malfunction, also check the relay R-Seat Heater.
• 📹 Rear view camera: fuse 10A in the additional block behind the glove compartment (marked as F-Camera).

In cars with panoramic roof (hatch) added fuse 25A for curtain drive (№40 in the cabin block). If the sunroof curtain stops moving, also check limit switches on the guides - their contamination often leads to false triggering of the protection.

What to do if the fuse is intact, but the circuit does not work?

If the fuse is good, but the device (for example, a radio or headlight) does not work, the problem may be:

1. A burnt-out relay (check for a click when the circuit is turned on).
2. Oxidized contacts of the fuse box (clean them with an eraser or special liquid).
3. A broken wire or a malfunction of the device itself (test the circuit with a multimeter).
4. Malfunction of the control unit (for example, BCM or ECM).

In such cases, diagnostics using a scanner is recommended (for example, Launch X431 or ELM327).

Frequently asked questions about Qashqai J10 fuses

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

For the cigarette lighter in Qashqai J10 fuse responds No. 7 (15A) in the salon block. It burns out due to:

• Use of devices with consumption >120 W (for example, compressors or inverters).
• Short circuit in the cigarette lighter socket (check the contacts for oxidation).
• Connecting several consumers through a splitter without protection.

Solution: replace the fuse with a similar one (15A) and use a power strip with a built-in fuse for high-power devices.

Is it possible to install a fuse of a higher rating if it constantly blows?

No! Increasing the fuse rating may result in:

• Overheating and melting of wiring.
• Failure of the device that protects the fuse (for example, a window lift motor).
• Fire in case of short circuit.

If the fuse blows repeatedly, look for the cause (short circuit, faulty consumer) or contact an auto electrician.

Where is the fuel pump fuse located, and how can I check its operation?

The fuel pump fuse is No. 15 (15A) in the salon block. To check it:

1. Turn on the ignition (without starting the engine).
2. Listen: within 2-3 seconds you should hear the sound of the pump (buzzing from under the rear seat).
3. If there is no sound, check the fuse and relay R3 in the salon block.

Also check the voltage at the pump connector (should be 12V when the ignition is on).
