Nissan Cube Z10 (2009–2014): location and assignment of fuses

Nissan Cube Z10 - a compact hatchback with a unique design, released between 2009 and 2014. Despite the non-standard appearance, the electrical circuit of the car follows the classical canons Nissan, but has a number of features that are important to consider when diagnosing faults. Fuses and relays in Cube Z10 distributed over two main blocks: in the cabin (to the left of the steering wheel) and under the hood (next to the battery). Correctly identifying them saves time and prevents short circuits when replacing.

In this article you will find detailed description of each fuse and relay indicating the rated current, protected circuits and typical symptoms of their burnout. We will also look into common mistakes when replacing, which can lead to failure of the on-board electronics, and we will give recommendations for diagnostics using a multimeter. Particular attention is paid fuse F34 (10A) in the cabin unit, responsible for the operation of the system Nissan Intelligent Key - its burnout is often mistakenly diagnosed as a malfunction of the ignition key.

Where are the fuse boxes located in the Nissan Cube Z10

B Nissan Cube Z10 There are two main fuse and relay blocks:

• 🚗 Salon block — located to the left of the steering column, behind the plastic cover. To gain access, you need to turn the three latches 90° counterclockwise and pull the cover towards you. The block contains 38 fuses And 12 relays, responsible for internal electronics.
• 🔋 Engine compartment block — located next to the battery, under the black plastic cover. High current fuses (up to 120A) and relays associated with power circuits are concentrated here: starter, generator, cooling fans.

Additionally in Cube Z10 may be present third block - it is located in the luggage compartment (behind the trim on the left side) and contains fuses for the premium audio system Bose and rear parking sensors. This unit is not available in all trim levels, so its availability should be checked by VIN code.

Important: when working with the engine compartment Be sure to remove the negative terminal of the batteryto avoid short circuit. There is less risk in the cabin unit, but when replacing a relay (for example, R10 - fuel pump relay) it is also recommended to de-energize the system.

Interior fuse box: decoding and diagram

Salon block Nissan Cube Z10 labeled as «Fuse & Relay Box» and contains elements responsible for the vehicle’s comfortable systems. Below is a table with the purpose of each fuse and its rated current. Please note that The color of the fuse depends on the current strength:

Fuse no.	Rating (A)	Color	Protected circuit
F1	10	Red	Engine management system (ECM), throttle position sensor
F10	15	Blue	Cigarette lighter, 12V socket in trunk
F20	7.5	Brown	Control unit ABS, wheel speed sensors
F34	10	Red	System Nissan Intelligent Key, immobilizer
F38	15	Blue	Audio system, navigation, rear view camera

Features of the cabin unit:

• ⚡ Fuse F10 (15A) often burns out when using powerful devices in the cigarette lighter (for example, car vacuum cleaners). If it's burnt out, check socket for short circuit multimeter.
• 🔑 Fuse F34 (10A) - "weak point" Cube Z10. Its burnout leads to failure to start the engine with the key, although the starter may work. In this case, check the immobilizer circuit.
• 🎵 Fuse F38 (15A) protects the audio system. If after replacing it the radio does not turn on, check fuse in the device itself (often located on the back).

⚠️ Attention: When replacing fuses in the passenger compartment, do not use metal screwdrivers or other conductive objects - this may short out adjacent circuits. It is optimal to use the plastic tweezers that came with the car.

Engine compartment: high current fuses and relays

Engine compartment block Nissan Cube Z10 contains high rated fuses (from 30 to 120A) and relays responsible for critical systems:

• 🔥 fuse F1 (120A) - main fuse, protects the circuit from the battery to the fuse box. Its burnout leads to complete blackout of the car.
• ⚙️ Relay R1 (Starter relay) - if it malfunctions, the engine does not start, although there are clicks when turning the key.
• 💨 fuse F10 (30A) — responsible for cooling fans. If it burns out, the engine will overheat.

Arrangement of elements in the engine compartment:

┌───────────┬───────────┬───────────┐
│  F1 (120A) │  F2 (80A)  │  R1 (Стартер) │
├───────────┼───────────┼───────────┤
│  F5 (50A)  │  F6 (30A)  │  R5 (Главное)  │
│ (Генератор)│ (Вентиляторы)│   реле       │
└───────────┴───────────┴───────────┘

Typical problems:

• If fuse F6 (30A) burns out regularly, check fan motors for jamming or short circuit in the winding.
• Relay R1 (starter) may “stick” due to oxidation of contacts. In this case you can hear multiple clicks without cranking the engine.

⚠️ Attention: When replacing fuses F1 (120A) or F2 (80A) use only original elements Nissan with copper contacts. Cheap analogues with aluminum legs can melt under load.

How to check the starter relay without replacing?

If you hear clicks when you turn the key, but the starter does not turn, you can temporarily close the relay contacts R1 screwdriver (contacts 30 And 87). If the engine starts, the relay is faulty and needs to be replaced. Do this only with the gear in neutral and the battery terminal removed!

Typical faults and their diagnosis

B Nissan Cube Z10 There are several “weak points” in the electrical system that manifest themselves through fuses:

1. Cigarette lighter or 12V socket does not work - check F10 (15A) in the salon block. If the fuse is intact, the problem may be oxidized socket contacts or damaged wire.
2. Keyless entry system fails (Intelligent Key) - guilty F34 (10A). Also check immobilizer antenna (located around the ignition switch).
3. Power windows don't work - the fuse answers F25 (25A) and relay R7. If the fuse is intact, check gear motors for mechanical damage.

For diagnostics, use a multimeter:

• 🔋 Checking the fuse: Set mode 200Ω and check the resistance between the legs. A good fuse will show 0Ω.
• 🔌 Voltage check: one of the fuse contacts must have 12V (with the ignition on). If there is no voltage, the problem is in the circuit before the fuse.

If the fuse blows again after replacement, don't increase its value - this will lead to melting of the wiring. Instead:

1. Disconnect all consumers connected to this circuit.
2. Check the wiring for a short circuit.
3. Check devices (such as the radio or air conditioning compressor) for increased energy consumption.

💡

If the fuse F38 (15A) burns out when you turn on the radio, try resetting it to factory settings. Sometimes the cause is a damaged amplifier or speaker creating a short circuit.

How to properly replace a fuse or relay

Replacing fuses in Nissan Cube Z10 requires care, especially when it comes to relays or high-current elements. Follow this algorithm:

1. De-energize the system — remove the negative terminal of the battery (this is mandatory in the engine compartment!).
2. Use tweezers — in the passenger compartment, the fuses sit tightly in their sockets. Don't try to pull them out with your fingers.
3. Check out the new item — before installation, make sure that the rating matches (the current strength is indicated on the fuse body).
4. Reinstall — the fuse should go in without effort. If it is loose, the nest could be deformed.

For relay:

• 🔄 Relay in Cube Z10 have a standard connector ISO 280, but may differ in functionality. For example, relay R10 (fuel pump) and R11 (fans) are identical in appearance, but not interchangeable.
• 🔍 Before replacing a relay, check its functionality by connecting a similar one that is known to be working (for example, a horn relay).

⚠️ Attention: Never replace a fuse with a bug (wire or foil). B Cube Z10 this can cause wiring fires, especially in circuits ABS or ECM, where the current is strictly controlled.

💡

If the problem persists after replacing the fuse, check state of contacts in the socket - they could oxidize or burn. Clean them with alcohol or a special contact cleaner.

Frequently asked questions about Nissan Cube Z10 fuses

Why does it blow again after replacing fuse F10 (cigarette lighter)?

This indicates short circuit in the circuit. Most often the problem is:

• Damaged 12V socket (melted contacts inside).
• A short in the wire running from the fuse to the outlet.
• A faulty device connected to the cigarette lighter (for example, a charger with a damaged circuit).

Solution: disconnect all consumers, replace the fuse and connect devices one by one to find the culprit.

Can fuses from other Nissan models be used?

Yes, but with reservations:

• Fuses standard denominations (10A, 15A, 20A) suitable from Note, Micra or Juke - they use the same standard sizes.
• The relays must match number (For example, R10 from Tiida will not fit, even if it looks identical).
• Fuses maxi-fuse (30A–120A) in the engine compartment there must be original - analogues may not withstand inrush currents.

How to check if the fuse is blown without pulling it out?

Using a multimeter:

1. Turn on the ignition.
2. Set the multimeter to DC 20V.
3. Connect the black probe to ground (for example, the body), and the red one to both fuse legs one by one.
4. If on one of the legs 12V, and on the other 0V - the fuse has blown.

You can also use test lamp, but this method is less accurate.

Tips for preventing fuse problems

To keep the fuses in Nissan Cube Z10 served longer:

• 🔌 Do not overload the cigarette lighter — the maximum power of a 12V socket is 180W (15A × 12V). Connecting a vacuum cleaner or compressor may cause burnout F10.
• 💡 Check the status of your contacts - oxidation or corrosion increases the resistance, which leads to heating and blown fuse.
• 🔧 Inspect the blocks regularly - Dust and moisture can cause corrosion. Clean your contacts alcohol or a special cleaner (for example, CRC Contact Cleaner).

For owners Cube Z10 with audio system Bose:

• 🎵 Amplifier fuse (F38) often suffers due to speaker overload. Do not play music at full volume when the engine is off - this may cause a surge in current.
• 🔊 If the fuse burns when you turn on the radio, check speaker integrity (especially low-frequency ones) - a break in the voice coil causes a short circuit.

Remember: 90% of problems are with fuses in Cube Z10 associated either with short circuit, or with excess load. If you cannot find the cause yourself, contact an electrician with a diagnostic scanner (such as Launch X431), which will show the current in the circuits in real time.
