However, finding an exact decoding of the fuse box for this model can be difficult: the diagrams in the instruction manual are not always detailed, and the inscriptions on the cover of the block are erased over time.

In this article you will find current fuse diagram in the salon block Sunny FB15, their purpose with reference to specific circuits, as well as practical advice on diagnostics and replacement. We took into account the features of restyled versions (2014+), where the location of some fuses may differ. If you are looking for information on cigarette lighter fuse, which often blows due to the connection of powerful gadgets, or want to understand why the panel backlight does not work - here are the answers to these and other questions.

The material was prepared on the basis of official service manuals Nissan, as well as the experience of owners from forums Drive2 And Nissan Club Russia. All data has been checked for relevance for Russian and European versions Sunny FB15 with gasoline engines HR15DE And HR16DE.

Where is the fuse box located in the interior of the Nissan Sunny FB15

B Nissan Sunny FB15 The interior fuse box is located to the left of the steering column, behind a plastic cover. To access it, follow these steps:

1. Open the driver's door and turn the ignition key to the “ON” position** (it is not necessary to start the engine) - this will allow you to check the functionality of the circuits after replacement.

2. Click on latch at the bottom of the panel (under the steering wheel) and pull the cover towards you. It is attached to two plastic clips, so pull carefully so as not to break it.

3. Behind the cover you will see two blocks:

  • 🔧 Main fuse box (top, with the inscription FUSE) - fusible links for most circuits are located here.
  • ⚡ Relay block (bottom, with the inscription RELAY) - contains a relay for turning on the headlights, cooling fan and other powerful consumers.

There should be a sticker with a fuse diagram on the inside of the block cover, but often it is missing or erased. Below we will give full transcript taking into account the characteristics of different years of production.

💡

If the fuse box cover won't open, check to see if there is a carpet or alarm wires blocking it. Sometimes the clamps jam due to dust - carefully clean them with a dry cloth.

Diagram and decoding of fuses in the FB15 cabin

The table below shows current decoding of fuses for Nissan Sunny FB15 (2010–2017). The numbers correspond to the designations on the block cover. Please note: on models after restyling (2014+) fuses #10 And #20 may have a different purpose (indicated in parentheses).

Fuse no. Denomination (A) Purpose of the circuit Notes
1 10 Audio system, navigation Often burns out when there is a short circuit in the speakers
7 15 Cigarette lighter, 12V socket Burns out when connecting devices with a power >120 W (for example, compressors)
10 10 (15) Instrument panel illumination (before 2014) / Rain sensor (after 2014) May be empty on restyled versions
15 10 Window lifters (driver's) If only one glass does not work, check the motor, not the fuse

  • 🟢 Green (30A) — circuits with high consumption (stove fan, glass heating).
  • 🔴 Red (10–15A) - lighting, audio system.
  • 🟡 Yellow (20A) — power windows, cigarette lighter.
📊 How often do you check the fuses in your Nissan Sunny?
  • Only in case of breakdown
  • Once a year for prevention
  • Never checked
  • I don't know where they are

How to check and replace a fuse: step-by-step instructions

If any electrical appliance (for example, a radio or heated seats) stops working, the first thing to do is check the corresponding fuse. For this you will need:

  • 🔦 Flashlight (to inspect the block in the dark).
  • 🛠️ Tweezers or a special puller (usually included with the machine).
  • 🔋 Multimeter or tester (optional, for checking the circuit).

Algorithm of actions:

  1. Turn off the ignition and disconnect the negative terminal of the battery (this is mandatory to prevent short circuit!).
  2. Find the fuse number from the table above and remove it with tweezers.
  3. Inspect the fuse for light: if the jumper inside is burnt out - it needs to be replaced.
  4. Install a new fuse same denomination (never install bugs or higher amperage fuses!).

Disconnect the battery|Wear gloves (fuses may be hot)|Prepare spare fuses of the required rating|Check the circuit with a multimeter after replacement-->

If the new fuse blows immediately, this indicates short circuit in the circuit. In this case:

⚠️ Attention: Do not reinstall the fuse without diagnostics! This may cause the wiring to catch fire. Contact an auto electrician to check the circuit for an open or short.

Common problems and their solutions

Owners Nissan Sunny FB15 often encounter typical faults related to fuses. Here are the most common cases and how to resolve them:

1. The cigarette lighter or 12V socket does not work

  • 🔌 Check the fuse #7 (15A). If it is burnt out, replace it, but note: the reason may be faulty devicethat you connected (for example, in a compressor with a current >10A).
  • 🔍 Inspect the cigarette lighter connector for melting or oxidation. Often the problem lies in poor contact.

2. Power windows don't work

  • 🚗 Check the fuse #15 (10A) for the driver's window and #16 (10A) for passengers.
  • 🔧 If the fuses are intact, but the glass does not move, the problem may be window lift motor or control unit.

3. Headlights or panel illumination stopped working

  • 💡 For low/high beam, check the fuses #3 (10A) And #4 (10A), as well as relay #5 in the lower block.
  • 🔦 If the panel backlight does not light, inspect the fuse #10 (10A) And check the lamps — they often burn out at the same time.
What to do if the fuse is intact, but the device does not work?

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

1. **Wiring break** - check the circuit with a multimeter in continuity mode.

2. **Faulty relay** - swap it with a known working one (for example, a fan relay).

3. **Oxidized contacts** - clean the terminals of the fuse box with alcohol or a special spray.

4. **Malfunctions of the device itself** - for example, a burnt-out amplifier in an audio system.

Differences in fuses before and after restyling in 2014

In 2014 Nissan Sunny FB15 underwent restyling, which affected not only the appearance, but also the electrical circuit. Major changes to the fuse box:

Before 2014:

  • 🔹 Fuse #10 (10A) was responsible for instrument panel lighting.
  • 🔹 Fuse #20 (7.5A) protected the chain immobilizer.
  • 🔹 There was no fuse for rear view cameras (it was not included in the basic configuration).

After 2014:

  • 🔹 Fuse #10 (15A) became responsible for rain and light sensor (in versions with auto light).
  • 🔹 A fuse has appeared #25 (10A) for rear view cameras.
  • 🔹 Fuse #20 (7.5A) began to defend climate control unit.

If you are not sure about the year of your car, check VIN code (the first 4 characters will indicate the model and year). You can also focus on complete set: the presence of a rear view camera or auto light indicates that you have a version after restyling.

💡

On restyled versions (2014+) the fuse #10 may be empty if the machine is not equipped with a rain sensor. Do not confuse it with the backlight fuse!

FAQ: Frequently asked questions about Nissan Sunny FB15 fuses

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

No! Installing a fuse with a higher amperage (for example, 20A instead of 10A) may result in wiring fire. If the fuse blows repeatedly, look for the cause - usually a short circuit or a faulty consumer (for example, a window lift motor).

Where is the fuel pump fuse located?

B Nissan Sunny FB15 fuel pump fuse (15A) located not in the cabin unit, but under the hood - in the main fuse box next to the battery (fuse #32). Also check the fuel pump relay (#17 in the same block).

Why does it blow again after replacing the cigarette lighter fuse?

The reasons may be the following:

  1. You connect a device with a current >10A (for example, a car vacuum cleaner). Use splitter with fuse or connect powerful devices directly to the battery.
  2. Short circuit in the cigarette lighter wiring. Check the circuit with a multimeter.
  3. Malfunction of the connector itself (melted contacts). In this case, the socket needs to be replaced.

Which fuse controls the alarm?

The fuse is responsible for the operation of the alarm and central locking #20 (7.5A) in the salon block. If it is burned out, the car may not respond to the key fob or may not lock the doors. Also check the relay #8 in the lower block.

Is it possible to repair the fuse (soldering or twisting)?

Absolutely not! “Bugs” made of wire or foil are not designed to carry current and can cause fire. If you don't have a spare fuse on hand, temporarily disconnect the faulty circuit (for example, do not use the cigarette lighter), but do not repair the fuse using makeshift methods.
