Nissan Cube AZ10 - an iconic compact van with a unique design, Released in 2002 and produced until 2008. Despite its reliability, the electrical equipment of this car requires attention, especially when it comes to fuses and relays. Owners often encounter problems: the power windows don’t work, the audio system fails, or the dashboard lights stop lighting. In 90% of cases, a blown fuse is to blame - but where to look for it and how to replace it correctly?

In this article you will find complete fuse box diagram for Nissan Cube AZ10 (including restyled versions 2005–2008), decoding of each element indicating the current strength, as well as unique nuances that are not described in the official manual - for example, why the fuse F22 often lights up when connecting an aftermarket radio or how to check the cooling fan relay without a multimeter. We will also look at common replacement mistakes and give tips on prevention.

Where is the fuse box located in Nissan Cube AZ10?

B Cube AZ10 provided two main fuse boxes:

  • 🚗 Main unit — located under the hood, next to the battery (driver's side). It is closed with a plastic cover with the inscription FUSE & RELAY BOX.
  • 👤 Indoor unit — located in the cabin, under the instrument panel to the left of the steering column. To gain access, you need to unclip the plastic cover (it is secured with two latches).

Important: in the restyled versions (2005–2008), the arrangement of the blocks has not changed, but Some fuse numbers and assignments may vary. - This is especially true for fuses responsible for the audio system and climate control. If your Cube equipped with factory navigation or heated seats, the diagram must be clarified by the VIN code.

To avoid confusion, remember a simple rule: all fuses related to the engine and external lighting are located under the hood. The interior contains elements responsible for comfort - power windows, cigarette lighter, radio, etc.

Diagram and decoding of fuses under the hood

Engine compartment block Nissan Cube AZ10 contains 20 fuses and 6 relays. Below is a table with a breakdown of the most important elements (the numbers correspond to the designations on the block cover).

Number Current (A) Purpose Notes
F1 10 ECU (engine control unit) When burning, the engine stalls or does not start
F5 15 Fuel pump, injectors If the fuse is blown, the car will not start.
F10 10 Radiator cooling fan Often lights up when there is a short circuit in the temperature sensor circuit
F15 15 ABS, stability control system When burned, the lamp lights up ABS on the dashboard
F20 10 Side lights (left side) If the lights do not light up, also check F21 (right side)

Particular attention should be paid to the fuse F10 (cooling fan). B Cube AZ10 with engines HR15DE And KR15DE it often fails due to overheating of the contacts in the temperature sensor connector. If the fan does not turn on when the engine warms up, check not only the fuse, but also the connector on the radiator - it may be oxidized.

⚠️ Attention: Never replace a fuse F5 (fuel pump) to an element with a higher rating! This may lead to fire due to overheating of the wiring. If the fuse blows repeatedly, look for a shorted circuit or pump malfunction.

Interior fuse box: what is where

Indoor unit Cube AZ10 contains 15 fuses and 3 relays. He is responsible for the operation of the interior electronics. Below is a breakdown of the key elements:

  • 🔊 F7 (10A) - audio system, antenna. It often lights up when connecting a non-standard radio with high consumption.
  • 🚪 F9 (20A) - window regulators. If the fuse is blown, check the motors for short circuits.
  • 💡 F12 (10A) — dashboard lighting, brightness control. When burned, the backlight dims or goes out.
  • 🔌 F14 (15A) - cigarette lighter, 12V socket. One of the “weakest” fuses burns when connecting powerful devices (for example, a compressor).

Features of the cabin unit - fuse F11 (10A)who is responsible for the work immobilizer and alarms. If it burns out, the car may not start, and the indicator on the dashboard will flash KEY. In this case, do not rush to change the fuse - first check the circuit for a short circuit, especially if an alarm or additional equipment was recently installed.

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

Replacing the fuse in Nissan Cube AZ10 - a simple procedure, but there are nuances that will help you avoid mistakes. Here step-by-step algorithm:

  1. Turn off the ignition and disconnect the negative terminal of the battery (this is mandatory to avoid short circuit!).
  2. Remove the fuse box cover (it is secured with two latches under the hood and one in the passenger compartment).
  3. Locate the blown fuse. Usually he has broken thread or melted body. If you can’t determine it visually, use a multimeter in continuity mode.
  4. Remove the fuse special forceps (they are in the block) or tweezers. Never use metal objects - this can damage the contacts!
  5. Install a new fuse same denomination. If you don’t have the original one at hand, you can temporarily use a “bug” made of wire of a suitable cross-section, but only to get to the store!
  6. Connect the battery and check the circuit operation.

If after replacement the fuse burns out again, do not repeat the procedure - this indicates a short circuit in the circuit. In this case, you need to check the wiring for damage or contact an auto electrician.

💡

If the fuse F7 (audio system) burns out when you turn on the radio, try disconnecting the antenna - sometimes the problem lies in its circuit. Also check if the speakers are shorted (especially if they were recently replaced).

Typical problems and their solutions

Owners Nissan Cube AZ10 often encounter recurring problems with fuses. Here are the most common cases and how to fix them:

  • ⚡ The fuse often blows F14 (cigarette lighter) - the reason is usually the connection of powerful devices (compressors, inverters). Solution: Use a fused power strip or connect devices directly to the battery.
  • 🔊 fuse F7 lights up when the radio is turned on - Check the antenna and speaker circuits. If the problem persists, the amplifier or the radio itself may be faulty.
  • 🚗 After replacing the fuse F5 (fuel pump) car won't start — make sure that the pump is running (a buzzing sound should be heard when you turn on the ignition). If not, check the pump relay (it is located in the engine compartment).
  • 💡 Dimensions on one side do not work - check the fuses F20 (left side) and F21 (right), as well as lamps and connectors in the headlights.

One of the most insidious problems is intermittent fuse blowing F10 (cooling fan). If this happens regularly, check:

  • Condition of the temperature sensor connector (often oxidizes).
  • The operation of the fan relay (it is located in the engine compartment, next to F10).
  • Integrity of wiring from sensor to control unit.
What to do if the fuse is blown F11 (immobilizer)?

If after replacing the fuse F11 The car won't start and the light is flashing KEY, try this:

1. Disconnect the battery for 10 minutes, then connect again - this will reset the immobilizer errors.

2. Check the immobilizer antenna circuit (located around the ignition switch).

3. If the problem persists, the immobilizer unit itself or the chip in the key may be faulty. In this case, you will need diagnostics from an authorized dealer or an auto electrician with equipment for reflashing keys.

Relay in Nissan Cube AZ10: location and verification

B Cube AZ10 The relays are located together with the fuses in the engine compartment and cabin blocks. They are responsible for controlling powerful consumers - starter, fan, fuel pump, etc. Below is a list of the main relays and their purpose:

Number Purpose Symptoms of a problem
R1 Starter relay When you turn the key you hear clicks, but the starter does not turn
R3 Fuel pump relay The engine does not start, the pump cannot be heard when the ignition is turned on
R5 Cooling fan relay Fan does not turn on when overheated, fuse F10 burns out
R7 Low beam relay Both low beam headlights do not work

To test the relay, follow these steps:

  1. Remove the relay from the block (it can be removed by lightly pressing the latch).
  2. Ring the contacts with a multimeter 85 And 86 (coil). Resistance must be within 50–120 Ohm.
  3. Apply 12V voltage to the contacts 85 And 86 - a click should be heard (contacts closing 30 And 87).
  4. If the relay does not click or the contacts do not close, replace it.
⚠️ Attention: Relay R3 (fuel pump) and R5 (fan) often fail due to overheating. If you notice that the relay housing is melted or blackened, replace it without waiting for complete failure - this can save fuses and wiring from damage.
💡

If the starter relay (R1) clicks, but the starter does not turn, the problem may be in the starter itself or in its power supply circuit. Check the voltage at the contact 50 (thin wire) when turning the key - if it is not there, the ignition switch or wiring is faulty.

Prevention: how to extend the life of fuses

To avoid common problems with fuses in Nissan Cube AZ10, follow these tips:

  • 🔧 Check the status of your contacts regularly in fuse blocks. Oxidation or weakening of contacts leads to overheating and burning of fuses.
  • 🔌 Do not connect powerful devices (compressors, inverters) to the cigarette lighter without a splitter with a fuse.
  • 🎵 When installing a non-standard radio use a separate fuse for the positive wire (recommended rating is 10A).
  • 🚗 Check the cooling fan circuit periodically, especially if the fuse F10 already burned out. Clean the temperature sensor connector from oxidation.
  • 🔦 When replacing lamps (especially in headlights) do not touch the bulb with bare hands - grease marks lead to overheating and failure of fuses F20/F21.

If you often encounter electrical problems, it's worth get a spare set of fuses different denominations. B Cube AZ10 the most popular are 10A and 15A. It is also useful to have tweezers for removing fuses and a multimeter for checking circuits.

Don't forget that fuses are the weak link, which protects more expensive equipment. If they burn out too often, this is a sign of a more serious problem that is best addressed early.

FAQ: Frequently asked questions about fuses Nissan Cube AZ10

Is it possible to replace the fuse with a higher rated element?

No, this is extremely dangerous! The fuse is designed for a certain current, and if you install a element with a higher rating, this can lead to overheating of wiring and even fire. For example, if you put 15A instead of 10A, the wires may melt before the fuse blows.

Why after replacing the fuse F7 The radio doesn't work?

There are several reasons:

  1. The fuse is not installed tightly - check that it is securely seated in the socket.
  2. The audio system relay has burned out (it is located in the cabin unit next to F7).
  3. The problem is in the radio itself - perhaps a short circuit in its circuits.

Try disconnecting the antenna and speakers - if after this the fuse does not blow, the problem is in one of these elements.

How to check a fuse without a multimeter?

If you don't have a multimeter at hand, you can use visual inspection or replacement method:

  • Visually: a burnt fuse has a broken thread or a melted body.
  • Replacement method: Install a known-good fuse of the same rating. If the circuit worked, the old fuse was blown.

You can also use test lamp (for example, a test screwdriver) to check the presence of voltage at the fuse contacts.

Where to find a fuse diagram for a restyled Cube AZ10 (2005–2008)?

The circuit for restyled versions is almost identical, but the fuse ratings for the audio system and climate control may differ. The exact diagram can be found:

  • B instruction manual (section Fuses and Relays).
  • On fuse box cover (the current diagram is usually shown there).
  • On specialized forums (for example, Nissan Club Russia or Cube Owners Forum).

If you have factory navigation or heated seats installed, it is better to check the diagram using the VIN code from the dealer.

What should I do if the fuse burns out immediately after replacement?

This indicates short circuit in the chain. Proceed like this:

  1. Disconnect all consumers connected to this circuit (for example, if the F14, turn off the cigarette lighter).
  2. Check wiring for damage (especially at kinks or near moving parts).
  3. If you cannot find the problem yourself, contact an auto electrician - he will diagnose using smoke test or megohmmeter.

Do not reinstall the fuse under any circumstances - this may damage the wiring or even cause a fire!
