If your headlights don’t work, your stove fails, your dashboard flashes, or your central locking stops opening, the first thing to do is check the mounting block.

In this article you will find full fuse diagram for Primera P11 after restyling, their location, decoding of each element, as well as step-by-step instructions for replacement. We'll also show you how to diagnose electronics problems and give tips on choosing quality fuses. We will pay special attention A common mistake when replacing a cooling fan relay that can cause the engine to overheat..

Where is the fuse box located in Nissan Primera P11 restyling

In the restyled version Primera P11 (1999–2002) The fuse and relay mounting block is located in two places:

• 🔧 Main unit — under the hood, next to the battery, in a plastic box with a black lid. To open it, you need to press the latch on top and pull the lid towards you.
• 🚗 Additional block — in the cabin, to the left of the steering column, behind the plastic panel. To access it you will need a screwdriver with a Phillips bit (two self-tapping screws).

Important: on some modifications (for example, with a diesel engine YD22DDTi) the fuse diagram may vary slightly. Always check the sticker on the back of the unit cover - the current decoding for your configuration is indicated there.

If you can't find the block, please take a look at wire color, suitable for it: the main unit usually has a harness with red and black wires (power and ground), and an additional one with gray and green (signal circuits).

Fuse diagram and decoding Nissan Primera P11 restyling

Below is a table with a breakdown of fuses for the most common configuration Primera P11 restyling (petrol engines SR20DE And QR20DE). Ratings are in amperes (A).

Fuse no.	Rating (A)	What is he responsible for?	Symptoms of a problem
1	10	Side light (left side), license plate light	The left side lights or license plate lights do not light up
7	10	Low beam (right headlight), reverse lamp	Right low beam or reverse gear does not work
10	15	Radiator cooling fan, temperature sensor	Engine overheating, fan does not turn on
15	10	Audio system, cigarette lighter, 12V socket	The radio or cigarette lighter does not work
20	20	Windshield wipers, windshield washer	The wipers or washer pump do not work

A complete fuse diagram for your modification can be found on the back of the mounting block cover. If the sticker has worn off, download official repair manual (section Fuse and Relay Box).

⚠️ Attention: fuse №10 (15A) responsible for the cooling fan. If it burns out, the engine may overheat, especially in traffic jams. Always carry a spare fuse of this rating with you!

Decoding the relay in the fuse block

In the mounting block Primera P11 restyling the following relays are installed (their location may vary depending on the year of manufacture):

• ⚡ Cooling fan relay - usually in position R1 (next to fuse #10). If the fan fails, it will not turn on even at high temperatures.
• 🔦 Low/high beam relay — R3 And R4. If one of the headlights stops working, check first the lamp, then the relay.
• 🚪 Central locking relay — R5. If it malfunctions, the doors will not open/close using the key fob.
• 💡 Turn signal and hazard warning relay — R6. If they blink too quickly or don't work at all, the relay is to blame.

To test a relay, you can swap it with a known good one (for example, turn signal and fan relays are often interchangeable). If after replacement the problem disappears, the relay is faulty.

How to properly replace a fuse or relay

Replacing the fuse in Nissan Primera P11 - a simple procedure, but there are several nuances that will help you avoid mistakes:

1. Turn off the ignition and remove the negative terminal from the battery (this will prevent a short circuit).
2. Find the faulty fuse using the diagram or visually (a blown fuse has a broken thread inside).
3. Use special tweezers from the fuse kit or pliers with insulated handles.
4. Install a new fuse same denomination. Under no circumstances install a fuse with a large amperage - this may lead to a fire in the wiring!

If the new fuse blows immediately, this means there is some fault in the circuit. short circuit. In this case, it is necessary to check the wires for insulation damage or consumer failure (for example, a windshield wiper motor).

⚠️ Attention: On some modifications Primera P11 fuse №25 (10A) is responsible for the immobilizer. If it burns out, the car may not start. Always check this fuse if you have trouble starting!

Common problems with electrical equipment and their causes

Owners Nissan Primera P11 restyling often encounters the following faults related to fuses and relays:

• 🔥 The cigarette lighter fuse blows (No. 15, 15A) - the connection of powerful devices (for example, a compressor or inverter) is usually to blame. Solution: Use a power strip with a separate fuse.
• 💡 Turn signals or hazard lights do not work - check the relay R6 and fuse No. 5 (10A). Often the problem is oxidized contacts.
• 🚗 The central locking works randomly - the relay is at fault R5 or a damaged wire in the door (especially on the driver's side).
• ❄️ Furnace or air conditioner not working — check fuse No. 12 (10A) and heater fan relay.

If the problem persists after replacing the fuse, you should test the circuit with a multimeter for a short circuit. To do this:

1. Disconnect the consumer (for example, disconnect the heater motor connector).
2. Install a new fuse.
3. If it does not burn out, the problem is with the consumer. If it burns out, look for a short circuit in the wiring.

How to find a short circuit in the wiring?

To detect a short circuit, disconnect all consumers in the circuit and connect them back one by one, observing the fuse. If the fuse blows when connecting a specific device (for example, a radio), the problem is there. If the short circuit remains, check the wiring harness for chafing of the insulation (especially at bend points, for example, at the doors or under the hood).

What fuses and relays to buy for replacement

For Nissan Primera P11 restyling fits standard fuses knife type (blade fuse) of the following ratings: 5A, 7.5A, 10A, 15A, 20A, 25A, 30A. We recommend purchasing products from trusted brands:

• 🔹 Bussmann — high quality, reliable contacts, resistant to corrosion.
• 🔹 Littlefuse - original fuses used on the Nissan assembly line.
• 🔹 Hella - good price/quality ratio, easy to find in car stores.

For relays it is better to choose original spare parts Nissan (articles are listed in the catalog ETKA) or analogues from Bosch And Valeo. Cheap Chinese relays often fail, especially the cooling fan relay - it works under high load.

The cost of a set of fuses (a set of 10 pieces of different ratings) is from 200 to 500 rubles. An original fan relay will cost 800–1200 rubles, an analogue will cost 400–600 rubles.

Diagnosing faults using a multimeter

If the fuse or relay is good, but the device does not operate, diagnostics of the circuit will be required. To do this, you will need a multimeter (voltage and resistance test mode). Algorithm of actions:

1. Check availability fuse:
   • Turn on the ignition.
   • Connect one multimeter probe to one fuse contact, the other to ground (car body).
   • The voltage should be ~12V. If it is not there, the problem is in the circuit to the fuse.
2. Check continuity of the circuit after the fuse:
   • Disconnect the consumer connector (for example, headlight bulb).
   • Measure the resistance between the connector pins. If it tends to infinity, the wire is broken.

To check the relay:

1. Remove the relay from the block.
2. Connect the multimeter probes to the contacts 85 And 86 (control circuit). The resistance should be ~50–120 Ohms.
3. Apply 12V to the contacts 85 And 86 - a click should be heard (contacts closing 30 And 87).

If you are not confident in your skills, it is better to contact an auto electrician. Incorrect diagnosis can lead to damage to electronic components (e.g. ECU).

FAQ: Frequently asked questions

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

No! Installing a fuse with a large amperage may lead to wiring fire. If the fuse blows, this means that there is a short circuit in the circuit or the consumer is faulty (for example, a stove motor). It is necessary to find and eliminate the cause, and not increase the denomination.

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

This happens due to:

• Connections of powerful devices (for example, compressor or inverter).
• Short circuit in the cigarette lighter wires (often frayed under the dashboard).
• Malfunction of the cigarette lighter socket itself (oxidation of contacts).

Solution: Use a power strip with a separate fuse or test the circuit with a multimeter.

Where to find the fuse diagram for the diesel version Primera P11?

For diesel modifications (YD22DDTi) the fuse diagram is different. It can be found:

• On the back of the mounting block cover (if the sticker is still there).
• B official manual (section Fuse Box Diagram).
• On specialized forums (for example, Primera-Club).

What to do if the immobilizer fuse is blown?

Immobilizer fuse (№25, 10A) is responsible for communication between the chip in the key and the block ECU. If it burns out:

1. The car will not start (the starter turns, but the engine does not start).
2. The immobilizer indicator (key or flashing light) may be on the dashboard.

Solution: Replace the fuse and check the circuit for short circuit. If the problem persists, the immobilizer unit or reader antenna may be faulty.

Which fuse controls the radio in Primera P11?

The fuse controls the audio system №15 (15A) in the main block. If the radio does not turn on, also check:

• The fuse is in the radio itself (usually located on the rear panel).
• Integrity of the yellow wire (+12V constant) and red (+12V when ignition is turned on).
