Fuse box Nissan X-Trail T31 (2007–2013): diagram, location and decoding

Owners Nissan X-Trail T31 (2007–2013 model years) sooner or later face the need to check or replace fuses. The operation of all electrical equipment depends on their serviceability - from headlights and windshield wipers to the ignition system and multimedia. However, find exact information about the location and purpose of each element in the fuse box not so easy: manuals often lack detailed diagrams, and universal instructions do not take into account the specific features of the equipment.

This article will help you figure out where it is main fuse box And relay block in Nissan X-Trail T31, how to correctly identify and replace them, as well as avoid common diagnostic mistakes. We have collected current data for all modifications - petrol (QR25DE, MR20DE) and diesel (M9R), taking into account differences in electrical circuits for different markets (Europe, Japan, Russia).

Where is the fuse box located in Nissan X-Trail T31

B Nissan X-Trail T31 provided two main fuse boxes:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. Access to it is opened by turning three latches (on some versions - two).
• ⚡ Additional block under the hood — located next to the battery, in a plastic box with a lid. High power fuses are located here (for example, for the cooling fan or ABS system).

On diesel versions (M9R) may be present third block - next to the engine control unit (ECU), but it is rare and is responsible for specific circuits (for example, heating the fuel filter).

⚠️ Attention: On restyled models (2010–2013), the location of the fuses #30 (audio system) and #40 (cigarette lighter) may vary. Always check the sticker on the back of the unit cover!

To get to the cabin unit:

1. Open the driver's door and sit in the seat.
2. Pull the steering wheel adjustment lever towards you to its lowest position.
3. Press the three block cover latches (they are marked as PUSH) and remove it.

Diagram and decoding of the cabin unit fuses

Below is the current diagram for Nissan X-Trail T31 (2007–2013), including the most common configurations. Please note that Fuse numbers may vary depending on the year of manufacture and market (for example, Japanese versions have different numbering for the climate system).

Fuse no.	Denomination (A)	Purpose	Notes
1	10	Engine control system (ECU)	On diesel versions there is also a fuel pressure sensor
10	15	Audio system, navigation	Includes USB port and auxiliary input AUX
20	7.5	Dashboard, speedometer	When burned out, the indicators may flash ABS And Check Engine
30	15	Windshield wipers, windshield washer	On restyled models - also heated wipers
40	20	Cigarette lighter, 12V socket	Often burns out when using powerful devices (for example, compressors)

Important: Fuse #25 (10A) is responsible for the operation of the immobilizer. Replacing it with a fuse of a higher rating may block the engine from starting!

The complete diagram for your configuration can be found:

• 📄 On the sticker on the back of the fuse box cover.
• 🔧 In the electronic manual Nissan X-Trail T31 (section Fuses and Relays).
• 🌍 On official owner forums (for example, x-trail.su or clubxtrail.ru).

Location and purpose of the relay in the block

In the same cabin block, in addition to the fuses, there are relayresponsible for key vehicle systems. Their failure may be manifested by non-obvious symptoms - for example, non-functioning headlights with working lamps or starter failure without clicking.

Below is a list of the most important relays and their typical faults:

Relay designation	Purpose	Symptoms of a problem
R1	Starter relay	The starter does not turn, but clicks are heard
R5	Cooling fan relay	Engine overheating, fan does not turn on
R8	Fuel pump relay	The engine does not start, the pump cannot be heard
R10	Heated rear window relay	The heating filaments do not work, but the fuse is intact

To check the relay:

1. Remove the relay from the socket (by gently pulling up).
2. Call contacts 85 And 86 (winding) - resistance should be 50–120 Ohm.
3. Serve 12V to contacts 85 And 86 - a click should be heard and the contacts should close 30 And 87.

⚠️ Attention: Relay R8 (fuel pump) on diesel versions Nissan X-Trail T31 has a different pinout! Do not use relays from gasoline models - this may lead to failure of the high-pressure pump.

How to properly replace a fuse or relay

Replacing fuses in Nissan X-Trail T31 It seems like a simple procedure, but there are nuances that will help you avoid serious problems. For example, installing a fuse wrong denomination can lead to a fire in the wiring, and careless removal of the relay can damage the contacts of the unit.

Sequence of actions:

1. Turn off the ignition and remove the negative terminal from the battery (especially important when working with the fuel pump relay or ECU).
2. Use plastic tweezers supplied with the vehicle (metal tools may damage the contacts).
3. Check the new fuse for compliance with the rating (indicated on the housing and in the diagram).
4. Install the element all the way - it should fit tightly, without play.

Typical mistakes:

• ❌ Using “bugs” (wires instead of fuses) is direct cause of wiring fire.
• ❌ Replacing the fuse with a higher rating (for example, 10A instead of 15A) - leads to overheating of the circuit.
• ❌ Ignoring corrosion on the contacts of the unit - even a working fuse may not work due to oxidation.

If the fuse blows again after replacement, this indicates:

• 🔌 Short circuit in the circuit (check the wiring for exposed wires).
• 🔋 Problems with the consumer (for example, a faulty windshield wiper motor or audio system).
• ⚡ Power surges (check alternator and battery).

Diagnosis of faults based on symptoms

Often owners Nissan X-Trail T31 encounter problems that are caused by fuses or relays, but cannot identify them. Below is a table of typical symptoms and corresponding block elements.

Symptom	Possible fuse/relay	Additional checks
Headlights do not work (low/high beam)	#15 (10A), relay R3	Check the lamps and connectors in the headlight unit
Cigarette lighter doesn't work	#40 (20A)	Inspect the outlet for melting
Heater fan does not turn on	#28 (30A), relay R6	Check the heater resistor (located under the glove compartment)
Windshield wipers don't work	#30 (15A), relay R4	Check the wiper motor (accessed through the panel under the windshield)

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

1. Check all fuses visually (even if they look intact, sometimes the internal thread burns out).
2. Test the circuit with a multimeter in calls (resistance should be close to 0 ohm).
3. Swap similar relays (for example, R1 And R2) - if the problem has moved, the relay is faulty.

What to do if the fuse is intact, but the circuit does not work?

If the fuse is good, but the device (for example, a radio) does not work, check:

1. There is voltage at the fuse contacts (there should be 12V on both sides when the ignition is on).

2. Condition of connectors and wiring (contacts in the fuse box often oxidize).

3. The functionality of the device itself (for example, the radio can be checked by connecting directly to the battery).

Features of fuse blocks in different configurations

Nissan X-Trail T31 was supplied in various configurations, which affected the electrical circuit. For example, in versions with xenon headlights relay added R12 for the ignition unit, and in cars with climate control - fuse #35 (10A) for the automation system.

Main differences:

• 🔦 Gasoline vs diesel:
  • On diesel M9R fuse added #50 (15A) for glow plugs.
  • In petrol versions the fuse #45 (10A) is responsible for the system EVAP (catching fuel vapors).
• 🎵 Audio systems:
  • In basic configurations there is a fuse #10 (15A) is responsible only for the radio.
  • In versions with Bose fuse added #11 (20A) for amplifier.
• 🚗 Restyling 2010–2013:
  • Fuse added #55 (7.5A) for rear view camera.
  • Changed relay numbering for the system ABS (now R15 instead of R13).

To accurately determine your equipment, pay attention to:

• 📋 Sticker on the unit cover - the current diagram is indicated there.
• 🔧 VIN code (the first 3 characters will indicate the sales market: JN1 — Japan, VS1 - Europe).
• 📄 Electronic spare parts catalog (For example, Nissan EPC).

⚠️ Attention: On versions for the Japanese market (JDM) fuse #20 (7.5A) is responsible for the system ETCS (electronic traction control). Replacing it with a European analogue may lead to errors in the operation of the transmission!

Common problems and solutions

Owners Nissan X-Trail T31 often encounter typical faults related to the fuse box. Here are the most common ones and how to fix them:

• 🔥 The cigarette lighter fuse has blown (#40):

  The reason is usually the use of powerful devices (for example, car vacuum cleaners or compressors). Solution: Replace the fuse with the original one 20A and use a power strip with protection.

• 💡 The dimensions do not work, but the fuse is intact:

  Check relay R7 and contacts in the headlight unit. Often the problem is oxidation of the connectors.

• 🔋 After replacing the battery, the settings were reset:

  It's normal - in X-Trail T31 Some settings (for example, climate control) are reset when the power is turned off. Solution: Initialize the system (start the engine, let it run for 5 minutes, then turn the ignition off and on again).

• 🚨 The indicator is on ABS, but the fuse is intact:

  Check relay R13 (or R15 on restyled versions) and ABS sensor connectors on the hubs. Often the problem is a broken wiring.

If the problem cannot be solved by replacing the fuse or relay, it is recommended:

1. Test the circuit with a multimeter (in 200 Ohm to check for continuity).
2. Inspect the wiring for chafing (especially in bends under the hood).
3. Contact an electrician with a diagnostic scanner (for example, Launch X431), if the problem is related to ECU.

FAQ: Frequently asked questions about the Nissan X-Trail T31 fuse box

Where can I find a fuse diagram for my configuration?

The diagram is shown on the back of the fuse box cover. If it is not there or is unreadable, download the manual for your version on the website nicoclub.com.ru or check by VIN code in the catalog Nissan EPC.

Can fuses from other cars be used?

Yes, if they match the denomination and size. B X-Trail T31 standard fuses are used ATO/ATC (size "mini"). The main thing is not to exceed the specified denomination!

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

Most likely, there is a short circuit in the cigarette lighter socket or connected device. Check:

• Integrity of wiring from fuse box to outlet.
• No foreign objects inside the cigarette lighter socket.
• Condition of the connector contacts (often oxidize).

If the problem persists, replace the entire cigarette lighter socket.

How to test a relay without a multimeter?

You can use the "replacement method": temporarily install a known-good relay from another socket (for example, a fan relay R5 to the starter relay R1). If the problem disappears, the old relay is faulty.

What to do if the contacts in the fuse box are oxidized?

Clean contacts using:

• Special spray for electronics (for example, Kontakt 60).
• Fine-grain sandpaper (be careful not to damage the coating!).
• A toothbrush soaked in alcohol.

After cleaning, apply a thin layer of technical Vaseline or special contact lubricant.
