Nissan Qashqai 2008 fuses: complete diagram, location and replacement

Electrical system Nissan Qashqai the first generation (2008 release) is built on a complex network of fuses and relays that protect circuits from overloads. Without the correct operation of these elements, even a minor malfunction - for example, a blown cigarette lighter fuse - can result in the failure of important systems: from interior lighting to the engine control unit. In this article we will analyze exact fuse locations, their purpose, as well as the nuances of replacement, which are not written about in standard manuals.

Feature Qashqai 2008 (body J10) — availability two main fuse blocks: one in the cabin (under the steering wheel), the other in the engine compartment. However, their layout may differ depending on the configuration (for example, the presence of climate control or xenon headlights). We have collected current data for all modifications, including rare variants with additional relays for AWD-versions.

Where are the fuses located in the Nissan Qashqai 2008

B Qashqai J10 There are three key locations for installing fuses and relays:

• 🔧 Main cabin block — located to the left of the steering column, behind the plastic cover. The fuses for most internal systems (audio system, cigarette lighter, lighting) are located here.
• 🚗 Engine compartment block — located next to the battery (driver's side). Responsible for powerful circuits: starter, generator, cooling fans.
• ⚡ Additional relay block — in some trim levels it is installed behind the glove compartment or under the center console. Contains relay for ESP, ABS and all-wheel drive systems.

To gain access to the interior unit, just pull the plastic cover towards you (it is secured with two latches). In the engine compartment, the cover is attached to four clips - it must be carefully pryed off with a screwdriver so as not to break it. In models with diesel engine M9R the engine compartment circuit may include an additional relay for glow plugs, which is not present in gasoline versions.

If you cannot find the fuse box, check for service hatch under the steering wheel - in some modifications it is hidden under a decorative panel. To do this you will have to unscrew two screws. Torx T20.

Diagram and decoding of the cabin unit fuses

Salon block Nissan Qashqai 2008 contains fuses for 7.5A–30A, responsible for the internal systems of the car. Below is a table with the current decoding for most configurations (including Visia, Acenta And Tekna).

Fuse no.	Rating (A)	Purpose	Notes
F1	10	Airbag control unit (SRS)	When replacing, be sure to disconnect the battery!
F7	15	Cigarette lighter, 12V socket in trunk	Often burns out when using powerful devices (for example, compressors)
F10	10	Audio system, navigation	Available with Bose there may be a backup fuse F25
F18	15	Window lifters (all 4 doors)	When the mechanism jams, it burns out in 1–2 seconds
F23	7.5	Dashboard lighting, brightness control	If it is burnt out, check the lamps in the instrument cluster

Please note: in versions with xenon headlights fuse added F30 (10A) for the ignition unit. Its absence from a standard diagram is often confusing when diagnosing lighting problems.

⚠️ Attention: fuse F9 (10A) responsible for the work immobilizer. If it burns out, the car will not start and the key indicator on the dashboard will light up. Don't confuse it with a fuse F1 (SRS) — the consequences of an error can be critical to safety.

Underhood fuse box: what's where?

Engine compartment block Nissan Qashqai 2008 contains high rating fuses (from 20A to 100A) and relays for mission critical systems. Its location is next to the battery, under a plastic cover with the inscription FUSE & RELAY BOX.

The peculiarity of this block is the presence fuse links (fuses), which are similar in appearance to conventional fuses, but are designed for high currents. For example, insert 80A is responsible for the generator circuit, and its replacement requires special care.

• 🔋 F3 (60A) — main relay of the injection system. If it fails, the engine stalls immediately after starting.
• 💡 F10 (30A) — low/high beam circuit (left headlight). The right headlight uses a separate fuse F11.
• ❄️ F15 (40A) — radiator cooling fan. If it burns out, the engine will overheat.
• 🚘 F20 (100A) — fusible link for the starter circuit. Requires replacement when it "clicks" instead of starting.

Diesel versions have a relay added R7 for management turbine, and in cars with AWD - relay R12 for all-wheel drive clutch. These elements are often confused with fuses, but they are not interchangeable!

How to distinguish a fuse from a relay?

A fuse is a small plastic part with a transparent body, inside of which a metal thread is visible. A relay is a box with legs and an internal electromagnetic system (a slight knocking sound is heard when shaken).

Typical fuse problems and their causes

Owners Nissan Qashqai 2008 often encounter repeated blown fuses. This signals hidden faults, which cannot be ignored. Here are the most common cases:

• 🔥 Cigarette lighter fuse (F7) burns out when connecting powerful devices (for example, 12V refrigerators). Solution: use a protected power strip or connect devices directly to the battery.
• 🚪 Power window fuse (F18) burns out due to freezing or clogging of the guides. Before replacing, clean the mechanism and lubricate it with silicone grease.
• 🎵 Audio fuse (F10) fails when there is a short circuit in the speakers or wires. Check the circuit with a multimeter.
• 🔦 Headlight fuses (F10/F11) light up when installing LED lamps without voltage adjustment. For Qashqai Lamps with built-in stabilizer are recommended.

In models with the system Start/Stop (rare option for 2008) fuse F27 (15A) is responsible for the automatic start module. Replacing it without diagnosing the control unit may lead to an error P1614.

⚠️ Attention: If the fuse F3 (60A, injection) burns out for no apparent reason, do not rush to change it. This may indicate a short circuit in the wiring harness under the hood (the injector area is often affected). In this case, a complete electrical diagnostic is required.

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

Replacing the fuse in Nissan Qashqai 2008 It seems like a simple procedure, but mistakes here can lead to serious consequences - from damage to electronics to fire. Follow this algorithm:

1. Turn off the power. Remove the negative terminal from the battery or turn off the ignition (for cabin unit fuses).
2. Find the faulty fuse. Use the circuit from the previous sections or a multimeter in dial mode.
3. Remove the fuse. Use the special tweezers that came with the car. Don't pull the wires!
4. Check the circuit. If the new fuse blows immediately, look for a short (see next section).
5. Install a new fuse. He must be same denomination. Installing a larger fuse will damage the wiring.

For fuses under the hood (eg F3 or F20) additionally:

• 🛠️ Use dielectric gloves - these circuits are under high voltage.
• 🔍 Before replacing, clean the contacts of the unit from oxidation (you can use a spray CRC 2-26).

If you are replacing fuse link (For example, 80A or 100A), it needs to be soldered or special crimp terminals used. Regular twisting will lead to heating and repeated breakage.

Short circuit diagnostics: what to do if the fuse burns out repeatedly

If a new fuse blows immediately after installation, there is short circuit (short circuit). B Nissan Qashqai 2008 Most often, short circuit occurs in the following places:

• 🔌 Wiring under the seats — frays due to vibrations (especially in the rear of the cabin).
• 💡 Headlight wiring harness — the contacts oxidize or the insulation of the lamps is frayed.
• 🚗 Wires under the hood — suffer from high temperatures (for example, the exhaust manifold).
• 🔋 Generator circuit — when the brushes or diode bridge wear out, voltage surges occur.

For diagnostics you will need a multimeter in mode calls or resistance measurements. Verification algorithm:

1. Disconnect all consumers in the circuit (for example, if the cigarette lighter fuse blows, disconnect the 12V socket).
2. Remove the fuse and connect the multimeter probes to its contacts in the block.
3. If the device shows 0 ohm — there is a short circuit in the circuit. If the resistance is infinite, the problem is in the fuse itself or the consumer.
4. Disconnect sections of the circuit (connectors, wires) one by one to localize the location of the short circuit.

B Qashqai with the system ESP short circuit in the circuit F22 (10A) may block work ABS. In this case, two lamps light up on the dashboard at once: ABS And ESP OFF.

How to test a circuit without a multimeter?

You can use a test lamp (12V) with wires. Connect it instead of a fuse: if the lamp burns at full intensity, there is a short circuit in the circuit. Dim light indicates high resistance (eg oxidized contacts).

Where to buy fuses for Nissan Qashqai 2008: originals and analogues

For Nissan Qashqai J10 Fuses of standard sizes are suitable:

• Mini Blade (for the cabin unit, denominations 5A–30A).
• Maxi Blade (for the engine compartment, ratings 20A–100A).
• Fuse links (for starter/generator circuits, ratings 80A–120A).

Original fuses Nissan have articles like 28510-XXXX, but they can be replaced with analogues from Bosch, Hella or Littlefuse. The main thing is to comply with the rating and type of case. For example:

Rating (A)	Original article	Analogue (Littlefuse)	Approximate price (RUB)
10	28510-1M000	LMF 10	50–80
20	28510-1M200	LMF 20	60–100
30 (Maxi)	28510-5M300	MAX 30	120–180
80 (fuse link)	24060-4M800	MIDI 80	300–500

It is better to buy fusible links in specialized stores (for example, Exist.ru or Autodoc), since fakes often have a reduced wire cross-section, which leads to heating.

⚠️ Attention: Online stores often sell “universal” sets of fuses with ratings that do not correspond to the declared ones. Before purchasing, check the dimensions and markings - original fuses Nissan have the manufacturer's logo on the body.

Frequently asked questions (FAQ)

Why doesn't my Qashqai 2008 have fuse F25, which is indicated in the diagram?

In basic configurations (Visia) fuse F25 may be absent, since it is responsible for additional options (for example, heated seats or an audio system Bose). Check that your machine has the appropriate equipment.

Is it possible to replace fuse F3 (60A) with a higher rating if it keeps blowing?

No! This fuse protects the fuel injection circuit. Installing a fuse of a higher rating (for example, 80A) can lead to overheating of the wiring and even a fire. Instead, look for the cause of the short circuit (see diagnostic section).

Which fuse controls the heated seats?

In most configurations this is a fuse F28 (20A). If it is working, but the heating does not work, check the relay R11 in the cabin unit and the integrity of the heating elements in the seats.

What should I do if, after replacing fuse F7, the cigarette lighter still does not work?

Check:

1. The integrity of the wiring from the fuse box to the 12V socket (often frays under the dashboard).
2. The voltage at the socket contacts with a multimeter (should be 12V with the ignition on).
3. The condition of the outlet itself - sometimes the contacts inside oxidize or burn out.

Where is the starter relay located and how can I check it?

Starter relay in Qashqai 2008 located in the engine compartment (position R5). To check its functionality:

1. Remove the relay and inspect the contacts for oxidation.
2. Test the winding with a multimeter - the resistance should be within 50–120 Ohm.
3. When submitting 12V A clicking sound should be heard at the control contacts.

If the relay is OK, but the starter does not work, the problem may be in the starter itself or in the control circuit (check the fuse F20).
