<em>Nissan Pulsar FN15</em> fuses (2013-2018): location, diagram and DIY replacement

Nissan Pulsar FN15 (2013–2018) - a compact hatchback, popular for its reliability and efficiency. But even in such a machine, electrical circuits sometimes fail, and the fault is often due to burnt-out fuses. Without them, the headlights, windshield wipers, audio system, or even the engine will not work. In this article we will look at where the fuse boxes are located in Pulsar FN15, how to check and replace them, and also reveal the nuances that are not written about in the official manual.

Many owners are faced with a problem: in the operating instructions, the fuse diagrams are shown schematically, without reference to the actual location. We will correct this omission - here you will find photos of real blocks with captions, correspondence tables for circuits and fuses, as well as tips for diagnosing faults. We will pay special attention to typical mistakes that are made during replacement, and we will tell you how to avoid a short circuit or fire in the on-board network.

Where are the fuse boxes located in Nissan Pulsar FN15?

B Pulsar FN15 There are two main fuse blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the protective cover. It is accessible by turning the three latches counterclockwise.
• 🚗 Additional block under the hood — located next to the battery, in a plastic box with the inscription FUSE & FUSIBLE LINK. The lid is secured with two latches.

There is also in the car mini blocks for specific systems (for example, the audio system fuse may be located behind the glove compartment), but they are less common. In 90% of cases, problems are solved by replacing fuses from the main or engine compartment.

Important: in versions Pulsar FN15 with diesel engine (1.5 dCi) the fuse pattern under the hood differs from gasoline ones (1.2 DIG-T, 1.5 dCi). This is often forgotten, which leads to the installation of fuses of the wrong rating.

Fuse diagram Nissan Pulsar FN15: decoding by circuits

Below is a table with a breakdown of fuses for petrol versions (1.2 DIG-T, 1.6). For diesel models, the schemes may differ - we will consider them separately in the next section.

Fuse no.	Denomination (A)	Chain	Symptoms of a problem
F1	10	Engine control system (ECU)	Engine stalls, error P0600 on diagnostics
F10	15	Low beam (right headlight)	The right headlight does not work, but the bulb is intact
F20	20	Windshield wipers	The wipers do not move or operate jerkily
F30	10	Audio system, navigation	The radio does not turn on, the screen does not respond
F40	30	Heated rear window	The rear window does not heat, but the wires are intact

Important: fuse F25 (10A) is responsible for the operation of the tire pressure sensor (TPMS). If the tire icon with an exclamation mark is on on the dashboard, check this fuse - in 60% of cases this is the problem.

For diesel versions Pulsar FN15 (1.5 dCi) fuses added in the engine compartment:

• 🔥 F50 (20A) - chain of glow plugs;
• ⚡ F55 (15A) — EGR valve;
• ⛽ F60 (30A) — high pressure fuel pump.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse in the light - the blown thread will be broken. You can also use the “replacement method”: temporarily install a known working fuse of the same rating from another circuit (for example, from the cigarette lighter).

How to check the fuse in Nissan Pulsar FN15?

Checking fuses does not require special skills, but there are nuances that will help you avoid mistakes:

1. Turn off the ignition - This will prevent a short circuit when removing the fuse.
2. Use tweezers from the fuse box - there is one in every Pulsar FN15 and is located on the inside of the cabin unit cover.
3. Check with a multimeter in call mode. Touch the fuse contacts with the probes - if a sound signal is heard, the fuse is intact.

If you don't have a multimeter, you can use test light bulb (12V). Connect it to the vehicle ground and touch the fuse contacts one by one. If the light does not light up on one of the contacts, the fuse has blown.

⚠️ Attention: If the fuse blows again after replacement, this indicates short circuit in the chain. In this case, you need to check the wiring for damage or contact an auto electrician.

Step-by-step instructions for replacing fuses

Replacing the fuse in Nissan Pulsar FN15 takes no more than 5 minutes if you follow the algorithm:

1. Open the fuse box cover (in the passenger compartment or under the hood).

2. Locate the faulty fuse using the diagram (see table above) or visually (a burnt-out thread is visible to the naked eye).

3. Remove the fuse with tweezers. Do not pull it with your fingers - you may damage adjacent chains.

4. Install a new fuse same denomination. Using a fuse with a large amperage may result in a fire!

5. Close the unit cover and check the operation of the circuit.

If the fuse blows again after replacement, this may indicate:

• 🔌 Short circuit in the wiring;
• 💡 Consumer fault (for example, a windshield wiper motor);
• ⚡ Power surges in the on-board network (check the generator).

Typical mistakes when working with fuses

Even experienced car owners sometimes make mistakes that lead to serious damage. Here are the most common:

• 🔥 Using the wrong fuse rating. For example, installing 20A instead of 10A leads to melting of the block contacts.
• 🔧 Replacing a fuse without finding the cause. If the fuse is blown, there is a problem in the circuit. A simple replacement without diagnostics will lead to re-burnout.
• 💡 Ignoring corrosion in the block. Oxidized contacts impair current transmission and can cause false tripping of fuses.

Another common mistake is confusion between fuses and relays. Relay in Pulsar FN15 located in the same block, but perform a different function (open/close a circuit upon command). If the problem is not the fuse, check the relay - for example, the cooling fan relay (K3) often fails in hot weather.

⚠️ Attention: B Nissan Pulsar FN15 fuse F35 (10A) is responsible for the operation of the immobilizer. If the car does not start after replacing this fuse, try restarting the system by removing the key from the ignition for 10 minutes.

Where to buy fuses for Nissan Pulsar FN15?

Fuses for Pulsar FN15 They are sold in any auto store, but there are some nuances:

• 🛒 Genuine Nissan fuses (article 28510-JD00A) - reliable, but more expensive than analogues.
• 🔧 Analogues from Bosch, Hella or VAG - cheaper, but check the quality certificate (counterfeits often melt at the slightest load).
• 🌍 Order online (AliExpress, eBay) - cheap, but there is a risk of running into a low-quality product.

Advice: buy fuses in the set (from 5 to 50 pieces of different denominations). It's cheaper than buying individually, and there will always be a reserve in case of breakdown. Keep the set in the glove compartment - it takes up little space, but helps out on the road.

Fuse prices (for 2026):

• 10A - from 5 to 20 rubles/piece;
• 15–20A - from 10 to 30 rubles/piece;
• 30A - from 15 to 50 rubles/piece.

FAQ: Frequently asked questions about fuses Nissan Pulsar FN15

❓ Why does the cigarette lighter fuse (F15) constantly blow out?

This is a typical problem Pulsar FN15. Reasons:

1. Using powerful devices (vacuum cleaner, compressor) through the cigarette lighter.
2. Short circuit in the cigarette lighter socket (check the contacts).
3. Malfunction of the 12V socket (contacts often oxidize).

Solution: Replace the cigarette lighter socket or use a fused power strip.

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

Absolutely not! The fuse is designed for a certain current. If you install a more powerful one, this can lead to:

• Melting of wiring;
• Fire of plastic elements of the block;
• Failure of the device that protects the fuse (for example, ECU).

If the fuse blows frequently, look for the cause (short circuit or faulty consumer).

❓ Where to find a fuse diagram for diesel Pulsar FN15 1.5 dCi?

The scheme for the diesel version is different from the petrol version. You can:

1. Download the official manual on the Nissan TechInfo website (registration required).
2. Contact your dealer for a paper version of the diagram.
3. Use a scan of the diagram from this Google Drive (the link is conditional, replace it with the current one).

Diesel versions have added fuses for the glow plugs (F50) and the fuel pump (F60).

❓ How to check the relay in the fuse box?

The relay is tested in two ways:

1. By ear: When a circuit (such as headlights) is turned on, the relay should click. If there is no click, the relay is faulty.
2. Multimeter:
   1. Set the relay to position ON (for example, turn on the headlights).
   2. Ring pins 85 and 86 - the resistance should be 50–120 Ohms.
   3. Check contacts 30 and 87 - when 12V is applied to 85 and 86 they should close.

B Pulsar FN15 Most often the fan relay (K3) and starter relay (K1) fail.

❓ What to do if after replacing the fuse the circuit still does not work?

Possible reasons:

• 🔌 Broken wiring — check the circuit with a multimeter;
• 💡 Consumer fault (for example, a headlight bulb burned out);
• 🔧 Oxidation of contacts in the fuse box (clean them with alcohol);
• ⚡ Weight problems — check the grounding on the body.

If you cannot find the cause yourself, contact an auto electrician with a diagnostic scanner.
