Nissan Patrol Y61 fuse diagram: where the blocks are located, decoding and replacement

Nissan Patrol Y61 is a legendary SUV, whose electrical circuit often becomes a headache for owners. This car's fuses and relays are spread across multiple blocks, and a malfunction can cause everything from the headlights to the fuel pump to fail. In this article you will find detailed diagrams of all fuse blocks indicating their location, the purpose of each element and step-by-step diagnostic instructions.

Feature Y61 — presence of two main blocks: in the salon (under the dashboard) and under the hood (near the battery). However, depending on the year of manufacture (1997–2016) and the configuration, the diagram may differ slightly. We took into account all modifications, including diesel TD42 and gasoline TB45E/TB48DE, as well as versions with 24V electrical for military and commercial models.

Where are the fuse boxes in the Nissan Patrol Y61

B Patrol Y61 There are three main locations for fuses and relays:

• 🔧 Main unit in the cabin — located under the dashboard on the driver’s side, behind a plastic cover. Access to it opens after unscrewing two screws or snapping off the clamps (depending on the year of manufacture).
• 🚗 Block under the hood — located next to the battery, in a plastic box with a lid. Often covered with a layer of dirt, making access difficult.
• ⚡ Additional relay block - in some versions it is installed behind the glove compartment or under the center console. Responsible for climate control, ABS and other options.

On diesel versions (TD42, ZD30) the block under the hood may contain fuses for 30A–40A for fuel pump and glow plugs. In gasoline (TB45E) elements responsible for the ignition system and cooling fans are also located here.

⚠️ Attention: In models with 24V electrically (for example, military versions), the fuses have double the rated voltage, but outwardly do not differ from the standard ones. Installation 12V elements in such circuits will lead to their instant combustion!

To avoid confusion, remember a simple rule: all fuses related to lighting and comfort are located in the passenger compartment, and those responsible for the engine and transmission are under the hood. The exception is the starter and generator relays, which can be placed separately.

Fuse diagram of the main unit in the cabin

Main fuse box in the passenger compartment Patrol Y61 contains elements responsible for:

• 💡 Lighting (dimensions, brake lights, instrument lighting)
• 🔊 Audio system and cigarette lighter
• 🚪 Central locking and power windows
• 🌡️ Climate control and heater fans

Below is a table with a breakdown of fuses for the most common version (1997–2010). To accurately determine the element number, refer to markings on the block cover - they may differ depending on the sales market (Japan, Middle East, Europe).

Number	Rating (A)	Purpose	Notes
1	10	Parking lamps (left side)	If burnt out, also check the relay #5 in the block under the hood
7	15	Cigarette lighter, 12V socket	Often fails when connecting powerful devices (compressors, refrigerators)
12	20	Window lifters (all windows)	If only the rear windows do not work, also check the fuse. #18
15	10	Dashboard lighting	When replacing, use only original fuses - Chinese analogues may melt
20	30	Heater fan	In versions with climate control, this fuse is also responsible for the control unit (ECU) of the system

To access the block, follow these steps:

Turn off the ignition and remove the key|Unscrew the two self-tapping screws securing the cover (or press out the clamps)|Carefully pull the cover towards you, it is attached to the guides|Before removing the fuse, check it with a multimeter in the “test” mode-->

⚠️ Attention: In models with full power accessories (For example, Patrol GR Y61) the block may contain an additional relay #23, responsible for heating the seats. Its absence in the standard scheme often misleads owners.

Fuse box under the hood: diagram and features

Block under the hood Nissan Patrol Y61 contains the most critical fuses and relaysrelated to the operation of the engine, transmission and safety systems. Its location depends on the modification:

• 🔋 In most versions it is located to the right of the battery, in a black plastic box with a lid.
• 🛢️ On diesel TD42 the unit can be moved closer to the windshield, next to the washer reservoir.
• ⚡ In versions with 24V the electrical unit has double insulation and yellow markings.

The peculiarity of this block is the presence fuse links (fusable links), which look like wires with thickenings. They are responsible for protecting the generator, starter and main power lines. If they burn out, the car may be completely de-energized.

Number	Rating (A)	Purpose	Item type
A	80	Main fuse	Fuse link
B	40	Fuel pump (petrol) / Glow plugs (diesel)	fuse
C	30	Radiator cooling fans	Relay + fuse
D	10	Engine control unit (ECU)	fuse

To check fuses, use a multimeter in 200Ω:

1. Отсоедините вставку от блока.
2. Прикоснитесь щупами к её концам.
3. Сопротивление должно быть близко к 0Ω. Показания "OL" (обрыв) означают перегорание.

Decoding the relay in Nissan Patrol Y61

Relay in Patrol Y61 are responsible for controlling powerful consumers: starter, fans, fuel pump, etc. Their malfunction appears chaotic: For example, the cooling fan may only turn on at high speeds or not work at all. Below is a diagram of the location of the relays in the main blocks.

B block under the hood the most important relays:

• 🔥 #1 — Starter relay (if there is a malfunction, the engine does not start, clicks are heard)
• 💨 #3 — Cooling fan relay (if it breaks, the engine overheats)
• ⛽ #5 — Fuel pump relay (if it fails, the engine stalls 2–3 seconds after starting)
• 🔋 #7 — Main relay (main relay), responsible for supplying power to the ECU

B salon Comfort relays are located:

• 🚗 #2 — Power window relay (if the windows break, they move jerkily or do not work)
• 💡 #4 — Low/high beam relay (if there is a malfunction, the headlights blink or do not turn on)
• 🔊 #6 — Audio system relay (if the radio fails, the radio does not turn on, despite a working fuse)

To test the relay use replacement method: Swap the suspect relay for a known good one (for example, the fan relay and horn relay are often interchangeable). If the device works after replacement, the relay is faulty.

How to test a relay with a multimeter?

1. Set the multimeter to “continuity” mode (or resistance measurement).

2. Connect the probes to the contacts 85 And 86 (relay coil). Resistance must be within 50–120Ω.

3. Serve 12V to these contacts - a characteristic clicking sound should be heard.

4. Check the resistance between 30 And 87 (power circuit contacts). In the off state - "OL", in the on state - 0Ω.

Frequent problems with fuses and relays in Patrol Y61

Nissan Patrol Y61 is known for several common electrical-related faults. Here are the most common:

• ⚡ Cigarette lighter fuse blown (#7, 15A) - occurs due to the connection of powerful devices (compressors, inverters). Solution: Use a splitter with a separate fuse or install 20A element (temporarily!).
• 💡 Headlights flickering or not working - the relay is at fault #4 in the interior unit or oxidation of contacts in the unit under the hood. Clean your contacts alcohol solution and lubricate Litolom-24.
• ⛽ The engine stalls 2–3 seconds after starting — the fuel pump fuse has blown (B, 40A) or faulty relay #5. Check also mass pump (often oxidizes).
• 🔥 Starter doesn't work - check the relay #1 under the hood and fusible link A (80A). If you hear clicks when you turn the key, but the starter does not turn, the problem is power cable from the battery.

The problem with fuse links. B Patrol Y61 they often burn out due to:

• 🔋 Short circuit in the generator circuit (check the diode bridge).
• 💦 Moisture getting into the block under the hood (especially important after washing the engine).
• ⚡ Voltage surges when “lighting” from another car.

⚠️ Attention: If in your Patrol Y61 installed winch, check the separate fuse for 100A–150A, which is often placed next to the battery. Its burnout can block the engine from starting!

How to properly replace a fuse or relay

Replacing a fuse or relay in Patrol Y61 It seems like a simple procedure, but there are nuances that will help avoid repeated breakdowns:

1. Turn off the ignition and remove the key. In some circuits (for example, audio systems), residual voltage can persist for up to 5 minutes.
2. Use tweezers included in the car kit - it prevents damage to the unit sockets. Do not pry the fuses with a screwdriver!
3. Check out the new item before installation. Even factory fuses can be defective (check with a multimeter).
4. Install a fuse of the same rating. Increasing amperage (for example, with 10A on 15A) will lead to a risk of fire in the wiring.
5. Check the chain after replacement. If the fuse blows again, look for a short circuit (short circuit) in the wiring.

To search for a short circuit, follow the algorithm:

1. Disconnect the consumer (for example, lights or fan) that protects the problematic fuse.
2. Install a new fuse. If it does not burn out, the problem is with the consumer.
3. If the fuse blows again, there is a short circuit in the wiring. Use the multimeter in mode 200Ω to check the circuit for an open or short to ground.

When replacing the relay, pay attention to contact markings. B Patrol Y61 Two types of relays are used:

• Type A - standard 12V relay with 4 contacts (for example, for a fan).
• Type B — relay with 5 contacts (used in the starter and fuel pump circuits).

Do not confuse them - installing the wrong type of relay can damage it control unit.

Diagnosis of faults based on symptoms

If in your Nissan Patrol Y61 If you're having electrical problems but don't know where to start, use this symptom diagnostic chart:

Symptom	Probable Cause	Actions
All devices on the panel do not work	Fuse blown #15 (10A) or the relay is faulty #7 (main thing)	Check the unit in the passenger compartment, clean the relay contacts
The engine does not start, the starter does not turn	Fuse link A (80A) or starter relay #1	Check the voltage at the starter when turning the key
Power windows don't work	fuse #12 (20A) or relay #2	Also check the ground on the doors (often oxidizes)
The headlights stopped working	Relay #4 or fuses #1/#2 (10A)	Check the lamps and contacts in the headlight unit
Cooling fan does not turn on	fuse C (30A) or relay #3, temperature sensor	Check the voltage at the fan connector

If the symptom does not match any of the above, use by elimination:

1. Check all fuses in the cabin and engine compartment.
2. Inspect the fusible links for breaks or melting.
3. Check the ground on the body (the mounting points under the battery often oxidize).
4. Check the voltage on the battery with the ignition on - it should be at least 13.8V.

B Patrol Y61 with diesel engines (TD42, ZD30) pay special attention to the glow plug fuse (B, 40A). Its burnout leads to difficult starting when cold, and can only be diagnosed with a multimeter - the light on the panel may light up.

FAQ: Frequently asked questions about Nissan Patrol Y61 fuses

Is it possible to install larger fuses if they keep blowing?

No! Increasing the fuse rating may result in wiring fire. If the fuse keeps blowing, it means there is a problem in the circuit. short circuit or overload. It is necessary to find and eliminate the cause, and not mask the problem.

Exception: temporarily (for example, while hiking) you can set the fuse one step higher (for example, 15A instead of 10A), but only to get to the service.

Where is the fuse for the radio in Patrol Y61?

The audio system fuse is located in salon, fuse box, position #7 (15A). However, if the radio does not turn on, also check:

• Relay #6 in the salon block.
• fuse #20 (10A) — is responsible for powering the antenna and amplifier.
• Mass on the body behind the radio (often oxidizes).

Why does it blow again after replacing the fuse?

This means that the circuit has short circuit (short circuit). Search algorithm:

1. Disconnect the consumer (for example, headlights or cigarette lighter).
2. Install a new fuse. If it does not burn out, the problem is with the consumer.
3. If the fuse blows again, there is a short circuit in the wiring. Use a multimeter to test the circuit for a short to ground.

B Patrol Y61 common places of short circuit:

• Wiring under the driver's mat (frayed).
• The connectors in the doors (oxidize and short out).
• Wires near the battery (are rubbing against the body).

How to check a fuse link without a multimeter?

If you don't have a multimeter at hand, use visual method:

1. Remove the fuse link from the block.
2. Examine it against the light - there should be continuous wire. If a break is visible, the insert has burned out.
3. Touch the insert with your hands - a burnt-out one often has melted areas.

For temporary repairs you can solder wire of a suitable cross-section, but this solution is short-lived - the insert will burn out again at the first load.

Where can I find a fuse diagram for my Patrol Y61 modification?

The scheme may differ depending on:

• Year of manufacture (1997–2016).
• Engine type (TD42, ZD30, TB45E etc.).
• Sales market (Japan, Middle East, Europe).

Where to look for the exact diagram:

1. Under the fuse box cover - often there is a diagram pasted there.
2. Repair manual for your modification (for example, Nissan Patrol Y61 Service Manual).
3. Owner forums (For example, Patrol4x4 or Nissan Club Russia).
4. Electronic catalogs type AutoData or Mitchell1.
