Where is the fuse box located in Nissan March?

Depending on the year of manufacture and configuration March (especially models K12 And K13) fuse boxes may be located in different places. Main points to pay attention to:

• 🔧 Main unit — located in the cabin, under the instrument panel on the driver’s side. To access it, you need to open the cover, which is secured with latches.
• 🔋 Additional relay block - often located next to the main unit or under the hood, next to the battery (in models with HR16DE engine).
• ⚡ Fuse box under the hood — in some configurations there is a separate block for high-voltage circuits (for example, for a cooling fan or injection system).

B Nissan March K13 (2010–2019) The main fuse box is usually hidden behind a plastic panel to the left of the steering column. To open it, pull the bottom edge of the lid - it will snap off without tools. In models K12 (2002–2010) the unit may be located under the glove compartment or behind the glove box.

If you can't find the block, please take a look at marking on the lid - often there is a diagram with fuse numbers. As a last resort, use section with diagrams below.

7	15	Low beam (right headlight)	Often burns out when installing LED lamps
12	20	Power windows, electric mirrors	If it fails, check the relay K5
18	10	Audio system, navigation	Responsible for nutrition CAN buses multimedia
25	15	Cigarette lighter, 12V socket	Often fails when connecting powerful devices

A complete diagram for your configuration can be found in instruction manual (section Fuses and Relays) or on a sticker under the unit cover. If you do not have a manual, download it electronically at official Nissan resource (vehicle VIN required).

How to decipher the symbols on the diagram?

Fuse (F1, F2...) and relay (K1, K2...) numbers may differ depending on the year of manufacture. For example, in European versions March The cigarette lighter fuse is marked as F25, and in Japanese - like F17. Always check the sticker on the unit cover!

Purpose of the relay in the fuse box Nissan March

Relay in Nissan March are responsible for controlling high current circuits such as the starter, cooling fans or headlights. Unlike fuses, which simply open the circuit when overloaded, relays control on/off devices on command from ECU or switches.

Here main relays, which are found in most configurations:

• 🔑 K1 - starter relay. If it fails, the engine will not start, although the starter may hum.
• 💨 K3 — cooling fan relay. If it burns out, the engine will overheat, especially in traffic jams.
• 🔦 K5 — power window relay. It often fails when the glass freezes in winter.
• 🚗 K9 - fuel pump relay. If it fails, the engine will not start (no pressure in the fuel rail).

To check the relay, remove it from the block and shake it - if you hear a rattling sound inside, this is a sign of a malfunction. You can also replace a suspicious relay with a known working one (for example, with the same numbers K2 And K4 often interchangeable).

How to check and replace the fuse in Nissan March

Replacing a fuse is a simple procedure, but there are several nuances that will help you avoid mistakes. Here step by step instructions:

1. Turn off the ignition and remove the negative terminal from the battery (especially if you are working with fuses ECU or fuel pump).

2. Locate the fuse box (see section with diagrams) and remove the cover.

3. Using tweezers (usually attached to the block cover), remove the suspicious fuse.

4. Check it visually or using a multimeter in test mode. A good fuse should show resistance 0 ohm.

5. Install a new fuse same denomination. Using a high ampere fuse may cause a fire!

If the new fuse blows immediately, this indicates short circuit in the chain. In this case, you need to check the wiring for damage or contact a service center for diagnostics.

Typical problems with the fuse box in Nissan March

Owners Nissan March often encounter several recurring problems related to the fuse box. Here are the most common ones:

• ⚡ Cigarette lighter fuse blown (F25) - occurs due to the connection of powerful devices (for example, compressors or inverters). Solution: use a protected power strip or connect devices directly to the battery.
• 🔦 Frequent low beam fuse blows (F7) - usually caused by installing LED lamps without a voltage corrector. Solution: return halogen lamps or install load resistors.
• 🚪 Window failure - can be connected to a fuse (F12), and with relays (K5) or motors. Solution: Check all three elements.
• 🔋 Oxidation of contacts in the block — leads to unstable operation of electrical equipment. Solution: Clean the contacts with alcohol or a special spray (for example, Contact Cleaner).

If the problem persists after replacing the fuse, it is necessary to carry out circuit diagnostics. For example, a blown fuse F1 (ECU) may indicate a short circuit in the wiring harness or a malfunction of the control unit itself.

⚠️ Attention! If after replacing the fuse F9 (fuel pump) the engine does not start, do not try to crank the starter repeatedly. This can lead to flooding of spark plugs or discharge of the battery. Check the voltage at the pump connector with a multimeter.

How to choose quality fuses for Nissan March

Not all fuses are created equal. Cheap Chinese analogues may have a reduced cross-section of the fuse link, which leads to false alarms or, conversely, a lack of protection. When choosing, pay attention to the following points:

• 🏭 Manufacturer - give preference to brands Littlefuse, Bussmann or Eaton. They supply fuses to assembly lines Nissan.
• 🔍 Marking - original fuses have a logo Nissan or code 28500-JD00A (for March K13).
• 📏 Size - in March fuses are used Mini Blade (small) and Regular Blade (standard). Don't get confused!
• 🔥 Denomination — never install a fuse with a current reserve. For example, instead of 10A can't bet 15A.

The cost of a quality fuse ranges from 50 to 200 rubles per piece. Sets of 10–20 fuses of different ratings can be found for 500–800 rubles. Buy them from trusted stores such as Exist.ru, Autodoc or from official dealers Nissan.

B Nissan March K13 fuse F18 (audio system) often fails when connecting a non-standard radio. If you are installing a new multimedia system, add an additional fuse to the circuit. 5A next to the battery.

Frequently asked questions about the fuse box Nissan March

Can fuses from other cars be used in Nissan March?

Yes, if they match type (Mini Blade or Regular Blade) and face value. For example, fuses Toyota or Honda are suitable if their parameters match. However, it is better to use original or certified analogues.

Why after replacing the fuse F7 (low beam) the lamp still doesn't come on?

There may be several reasons:

• Bulb burnt out (check both filaments).
• The contacts in the headlight socket have oxidized.
• The relay has failed K6 (light control).
• The wiring from the fuse box to the headlight is damaged.

Start by checking the lamp, then inspect the relay and wiring.

Which fuse is responsible for the alarm? Nissan March K13?

In most configurations, the alarm is controlled by a fuse F10 (10A) and relay K7. If the alarm does not work, also check fuse F18 (he is responsible for CAN bus, to which the alarm is connected).

What to do if the fuse box is melted?
