Nissan Patrol: complete decoding of fuses and relays (Y61, Y62)

Owners Nissan Patrol sooner or later you have to face the need to check or replace fuses. These small but critical elements protect the vehicle's electrical equipment from overloads and short circuits. Without them, even a minor fault in the wiring can destroy expensive components - from headlights to the engine control unit.

In this article we will take a closer look at where the fuse boxes are located in Patrol generations Y61 (1997–2016) and Y62 (2010–present), we will provide current diagrams with a breakdown of each element, and also tell you how to correctly diagnose and replace fuses without the risk of damaging the car. We will pay special attention to the typical problems that owners face, for example, why the cigarette lighter fuse often blows or why the power windows do not work after replacing the battery.

Where are the fuse boxes in the Nissan Patrol?

B Nissan Patrol fuses and relays are distributed over several blocks, the location of which depends on the generation of the car. In models Y61 (dorestayl and restayl) and Y62 the diagrams have fundamental differences, so it is important to know exactly what year of manufacture you have.

Main installation locations:

• 🔧 Main unit in the cabin - under the instrument panel on the driver's side (on Y62 accessible after removing the cover next to the steering column).
• 🚗 Additional block under the hood — next to the battery or in the engine compartment (on Y61 often hidden under a plastic cover).
• ⚡ Relay block - can be issued separately (for example, on Y62 The starter and cooling fan relays are in different places).

On Patrol Y62 (2010+) The interior fuse box is usually located to the left of the steering wheel, behind the plastic panel. To gain access, just pull the cover towards you (it is secured with latches). B Y61 (1997–2016) the block may be hidden deeper - sometimes it is necessary to unscrew the screws or remove part of the cladding.

Fuse diagram for Nissan Patrol Y61 (1997–2016)

B Patrol Y61 The fuse diagram depends on the configuration and year of manufacture, but the general structure remains the same. Below is a typical description for most modifications (including diesel TD42 and gasoline TB48DE).

Number	Ampere	Purpose	Notes
1	10A	Interior lighting, instrument lighting	Often burns out when installing LED lamps
5	15A	Cigarette lighter, 12V socket	On models with two sockets, the fuse is common - if one is overloaded, both are switched off
10	20A	Window lifters (all 4 doors)	If the power windows do not work, check the relay K5
15	10A	Engine control unit (ECU)	Replace only with the ignition off!
20	30A	Radiator cooling fan	When it burns out, the engine overheats

B Y61 There is also a separate relay box, which is often confused with fuses. For example, relay K1 is responsible for the starter, and K3 - for the low beam. If the problem remains after replacing the fuse, check the corresponding relay (sometimes it is enough to knock on it or clean the contacts).

⚠️ Attention: On diesel Patrol Y61 with engine ZD30 fuel pump fuse (F22, 15A) often fails when water gets into the fuel system. Before replacing, check the integrity of the fuel lines!

Fuse Diagram Nissan Patrol Y62 (2010–present)

Patrol Y62 received a more modern electrical circuit, where many fuses are duplicated or have a higher rating. For example, the cigarette lighter fuse is already here 20A (vs. 15A in Y61), and the engine control unit is protected by two fuses - main and backup.

Typical diagram for Y62 (gasoline VK56VD / diesel YD25DDTi):

• 🔥 F1 (10A) - Brake lamps, reverse.
• 💡 F7 (15A) - Low beam (left headlight).
• 🔌 F12 (20A) — Cigarette lighter and socket in the trunk.
• 🚪 F18 (25A) — Central locking, alarm.
• 📡 F23 (10A) — Audio system, navigation.

Feature Y62 — availability additional fuse box under the hood, where the elements responsible for:

• 🔋 Main relay of the injection system (R1).
• ⚡ Generator fuse (F30, 100A).
• 🔥 Ignition circuit fuse (F32, 40A).

How to check and replace a fuse in a Nissan Patrol

Diagnosis of fuses in Patrol does not require special tools, but it is important to follow the correct sequence to avoid damaging the electronics. Here are the step-by-step instructions:

1. Turn off the ignition and remove the terminal from the battery (especially if you are working with the unit under the hood).
2. Find the faulty fuse - visually (the burned out one has a broken thread) or using a multimeter in continuity mode.
3. Remove the fuse special forceps (usually included with the block) or tweezers. Do not use metal objects - risk of short circuit!
4. Install a new fuse the same denomination. Never install a “bug” or a higher amperage fuse!

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

• Check wiring for exposed wires or melted insulation.
• Disconnect consumers connected to this circuit (for example, additional equipment).
• If the problem is in the standard electrical system (for example, in the power window circuit), contact an auto electrician for diagnosis.

Disconnect all additional devices (recorder, radar detector, etc.)|Check the circuit with a multimeter for a short circuit|Inspect the connectors for oxidation|Check the operation of the relay in this circuit-->

⚠️ Attention: B Patrol Y62 with the system Intelligent Key (keyless entry) fuse F18 (10A) is responsible for the operation of the immobilizer. If it burns out, the car will not start even with a working key!

Typical fuse problems in Nissan Patrol

Owners Patrol often encounter repeated faults related to fuses. Here are the most common cases and their causes:

1. The cigarette lighter fuse often blows (F5/F12)

Reasons:

• 🔌 Use of powerful devices (compressor, refrigerator) without an adapter.
• 🔥 Short circuit in the outlet (often due to moisture).
• 🔄 Poor quality fuse (Chinese analogues may have a lower rating).

Solution: Install a power strip with a separate fuse or use an outlet in the trunk (if available).

2. Window lifters do not work (F10/F16)

Reasons:

• ⚡ Overload of the window lift motor (for example, when the windows become icy).
• 🔧 Worn guides or mechanical blocking.
• 🔋 Discharged battery (window lifters are sensitive to low voltage).

Solution: Before replacing the fuse, check the operation of the motor by applying voltage to it directly (12V).

3. The cooling fan fuse blows (F20/F25)

Reasons:

• 🌡️ Fan relay sticking (a common problem on Y61).
• 🔥 Short circuit in the fan motor (check with a multimeter).
• 💦 Moisture gets into the fan power connector.

Solution: Replace the relay and clean the contacts. If the problem persists, check the fan motor.

What to do if the fan does not turn on, but the fuse is intact?

Check the temperature sensor (at Y61 it is located in the radiator). If it malfunctions, there is no signal to turn on the fan. Also inspect the wiring from the sensor to the control unit.

Where to buy fuses for Nissan Patrol and which ones to choose

Fuses for Patrol They are sold in any auto store, but it is important to choose high-quality analogues to avoid repeated problems. Here's what the experts recommend:

• 🏆 Original Nissan - reliable, but expensive (about 50–100 rubles per piece).
• 🔧 Bosch or Hella — optimal price/quality ratio.
• ⚠️ Chinese no-name - often have a lower rating (for example, instead of 20A - 15A).

When purchasing, pay attention to:

• Denomination - must exactly match the required (for example, 20A, not 25A).
• Type - in Patrol fuses are used mini-blade (small) and maxi-blade (large, for high currents).
• Color - each denomination has its own color (for example, 10A - red, 20A - yellow).

To replace the relay, analogues from Hella or Febi. The main thing is a match by number (for example, K1 for the starter).

Frequently asked questions about Nissan Patrol fuses

Why did the power windows stop working after replacing the battery in the Patrol Y62?

This is due to the power window control unit being reset. To restore operation, you must:

1. Lower the window completely manually (if it is jammed).
2. Hold the lift button for 5-10 seconds after it is completely closed.
3. Repeat the procedure for each window.

If this does not help, check the fuse F16 (25A) and relay K5.

Is it possible to install a fuse of a higher rating if the standard one often blows?

Absolutely not! Increasing the rating will lead to overheating of the wiring and the risk of fire. If the fuse blows frequently, look for the cause:

• Short circuit in the circuit.
• Overload (for example, the device in the cigarette lighter is too powerful).
• Faulty relay or consumer (for example, fan motor).

Where is the radio fuse located in Patrol Y61?

B Y61 The audio system fuse is usually located in the main unit under number F23 (10A). If the radio does not work after replacing, check:

• Condition of connectors (oxidation of contacts).
• There is voltage on the power harness (should be 12V on the yellow wire).
• Amplifier fuse (if installed).

How to check the relay in a Nissan Patrol without replacing it?

A quick way to diagnose a relay:

1. Remove the relay from its socket.
2. Ring the contacts with a multimeter 85 And 86 (coil resistance should be 50–120 Ohms).
3. Apply 12V to the contacts 85 And 86 - there should be a click.
4. Call contacts 30 And 87 - in the closed state, the resistance should be 0 Ohm.

If the relay does not click or there is no continuity, it needs to be replaced.

What should I do if there is no diagram in the Patrol Y62 fuse box?

The diagram is usually printed on the back of the block cover. If it's not there:

• Take a photo of the block and find a breakdown of the fuse numbers in the manual.
• Use universal schemes for Y62 (for example from official Nissan documentation).
• Contact the owners forum Patrol (For example, Patrol4x4).
