Where is the fuse box in the passenger compartment? Nissan Sunny FB15

Unlike many cars, where the fuses are scattered across several blocks, in Sunny FB15 (2011–2017) the main cabin unit is located in one place - under the instrument panel on the driver's side. Exact location:

• 🚗 To the left of the steering column, under a plastic cover.
• 🔧 To gain access, you must open the driver's door and bend down to your feet.
• 🔍 The block cover has latch on top — it needs to be carefully pryed off with a screwdriver or a fingernail.

On the inside of the lid there is a fuse diagram indicating the number and purpose of each. However, the labels are often erased or written in English, making them difficult to find. Below we have provided current transcript for Russian and European versions Sunny FB15, including differences in trim levels.

• 🔢 Fuses are numbered left to right and top to bottom (eg F1, F2, ..., F30).
• 🔌 Located next to the fuses relay (usually larger in size).
• 📏 Fuse sizes: most - miniature for 10–20A, but there are also standard (regular) for 30A.

Please note: some versions Sunny FB15 (for example, for the Southeast Asian market) the location of the fuses may vary. If your diagram does not match the table below, check with instruction manual or use VIN decoder to clarify the configuration.

Decoding the fuses in the cabin Nissan Sunny FB15 (table)

The table below shows the current decoding of fuses for most versions Sunny FB15 (2011–2017). Specified number, rating (amps) And appointment each fuse. If your car is missing a fuse, this is normal, since the unit is unified for different configurations.

Number	Denomination (A)	Purpose	Notes
F1	10	Engine Management System (ECM)	Responsible for the operation of the ECU. Errors may occur during burnout P0600–P0606.
F5	15	Cigarette lighter/socket 12V	It often burns out when connecting powerful devices (for example, a compressor).
F10	10	Audio system (radio, amplifier)	If the radio does not turn on, also check the fuse F20.
F15	7.5	Dashboard lighting	When burned out, the backlight of the speedometer and tachometer dims or goes out.
F25	20	Window lifters (all doors)	If the power windows do not work, also check the relay K5.

A complete table for all 30–40 fuses can be downloaded from FAQ block at the end of the article. If you need a decoding for a specific fuse that is not listed above, ask a question in the comments - we will promptly add the information.

⚠️ Attention: Never install a fuse with denomination higher than specified - this can lead to a fire in the wiring! For example, if you install 15A instead of 10A, the risk of a short circuit increases significantly.

How to correctly replace a fuse in Nissan Sunny FB15

Replacing the fuse in the passenger compartment Sunny FB15 - a simple procedure, but requires care. Here are the step-by-step instructions:

Turn off the ignition and remove the key from the lock|Find the fuse box (to the left of the steering wheel)|Remove the block cover by prying the latch|Locate the faulty fuse (using the table or visually)|Remove it with special pliers (available in the block) or tweezers|Install a new fuse of the same rating|Check the operation of the system-->

If after replacement the fuse blows again, this is a signal about short circuit in the chain. In this case:

• 🔧 Check it out wiring for damage (especially in places of kinks).
• 💡 Turn off all additional equipment (radio, alarm, heating).
• 📋 Contact electrician for diagnostics - independent repairs without experience can aggravate the problem.

B Nissan Sunny FB15 a common problem with oxidation of contacts in the fuse block. If the fuse is apparently intact, but the system does not work, try removing it and cleaning the contacts WD-40 or alcohol and install it back.

What to do if the fuse is stuck?

If the fuse cannot be removed with pliers, do not use force as this may break the plastic latches on the unit. Instead:

1. Disconnect the negative terminal of the battery.

2. Gently wiggle the fuse with a flathead screwdriver (do not press too hard!).

3. If this does not help, heat the contacts with a hairdryer (no more than 60°C) - this will help remove oxides.

🔍 How can you tell if a fuse has blown?

A blown fuse can be identified visually - there will be broken metal thread. You can also use the multimeter in dial mode: if the device does not beep when you touch both contacts, the fuse is faulty.

⚡ Why does the cigarette lighter fuse blow out immediately after replacement?

This indicates short circuit in the chain. Common reasons:

• The insulation of the wires under the dashboard is damaged.
• A metal object got into the cigarette lighter socket.
• The connected device is faulty (for example, a short-circuited DVR).

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

🔧 Is it possible to replace the fuse with a higher rating?

Absolutely not! Each fuse has its own rating, designed for the maximum load of the circuit. If you use a fuse with a higher amperage (for example, 20A instead of 10A), the wiring may overheat and catch fire.
