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 power windows to the ignition system and climate control. However, finding an exact diagram of fuse blocks for this model can be difficult: manuals often lack up-to-date information, and information on forums is scattered.
In this article we have collected full decoding of fuses and relays for X-Trail T31 all trim levels, including diesel and petrol versions. You will learn where the main blocks are located, how to correctly identify a blown fuse, and what nuances are important to consider when replacing. We will pay special attention to typical problems - for example, why the cigarette lighter fuse often blows or why the dashboard backlight does not work after replacing the lamps.
For convenience, we divided the information into blocks (interior, engine compartment) and added interactive widgets — a survey, a checklist for diagnostics and spoilers with rare diagrams. If you are looking for a specific fuse (for example, for a radio or fog lights), use the search page (Ctrl+F).
Where are the fuse boxes located in Nissan X-Trail T31
B X-Trail T31 There are two main fuse blocks:
- 🔧 Salon block — located to the left of the steering column, under the plastic cover. To gain access, pull the tab at the bottom of the panel (no tools required).
- 🚗 Engine compartment block — located next to the battery, in a plastic box with latches. On diesel versions it can be additionally protected by a rubber boot.
Also found in some configurations third block — it is installed behind the glove compartment (on the passenger side) and is responsible for additional equipment (for example, heated seats or a rear 12V socket). Its availability depends on the year of manufacture and the market (European, Japanese or American versions).
Important: on restyled models (2010–2013), the location of the blocks has not changed, but fuse ratings may vary. For example, the cigarette lighter fuse in the pre-restyle is 15A, and in the restyle - 20A. We have noted all the differences in the tables below.
- 2.0 petrol (MR20DE)
- 2.5 petrol (QR25DE)
- 2.0 diesel (M9R)
- Other
Interior fuse box: diagram and decoding
The cabin unit contains most of the fuses responsible for comfort and safety. Its circuit is universal for all modifications T31, but numbers and purpose of elements may vary slightly. Below is the current transcript for European versions (2007–2013).
| Fuse no. | Denomination (A) | Purpose | Notes |
|---|---|---|---|
| 1 | 10 | Engine control system (ECU) | On diesel versions - 15A |
| 7 | 10 | Cigarette lighter/socket 12V (front) | Often burns out when using powerful devices (for example, compressors) |
| 10 | 15 | Audio system (radio, amplifier) | Also responsible for navigation (if installed) |
| 15 | 10 | Fog lights (front) | On restyle - fuse No. 16 |
| 20 | 15 | Window lifters (all 4 doors) | When replacing, check the contacts in the doorways for oxidation. |
The complete diagram of the interior unit can be downloaded here (PDF, 1.2 MB). Please note: Japanese versions X-Trail T31 fuse No. 12 (10A) is responsible for start-stop system, which is not available in European trim levels. If your vehicle is imported from Japan, please check with additional table.
⚠️ Attention: When replacing fuse No. 7 (cigarette lighter), do not install an element with a rating higher than 20A - this may lead to melted wiring or a fire. If the fuse blows repeatedly, check the circuit for a short with a multimeter.
☑️ Diagnosis of fuse faults
Engine compartment: high power fuses and relays
Engine compartment block Nissan X-Trail T31 contains fuses and relays responsible for power part of electrical equipment: starter, generator, cooling fans, headlights, etc. Its location depends on the type of engine:
- 🔋 On petrol versions the block is located to the right of the battery, under a plastic cover with the inscription
FUSE & RELAY BOX. - 🛢️ On diesel (M9R) - to the left of the battery, closer to the windshield. The cover can be secured with two latches.
A feature of the engine compartment block is the presence fuse links (fusable links), which are similar in appearance to fuses, but are designed for high currents (40–100A). Replacing them requires caution: do not use wire or homemade jumpers!
| element | Denomination (A) | Purpose | Type |
|---|---|---|---|
| F1 | 80 | Main fuse (connection to battery) | Fuse link |
| R2 | — | Cooling Fan Relay (Low Speed) | Relay |
| F10 | 30 | Electric Power Steering (EPS) | fuse |
| F15 | 40 | ABS control unit | Fuse link |
Critical information: If in your X-Trail T31 The electric power steering has stopped working, check the fuse first F10 (30A) in the engine compartment. In 60% of cases, the problem is solved by replacing it. However, if the fuse blows repeatedly, diagnostics are required. EPS block — the power transistor may fail.
How to test the cooling fan relay?
To test the relay R2 (cooling fan) follow these steps:
1. Remove the relay from the block (it is located next to the fuse F5).
2. Connect 12V voltage to pins 85 and 86 (for example, from a battery).
3. Check the resistance between pins 30 and 87 with a multimeter - it should be close to 0 Ohm.
If there is no resistance, the relay is faulty and requires replacement.
Typical fuse problems and their solutions
Owners Nissan X-Trail T31 often encounter repeated blowing of the same fuses. Let's look at the most common cases and ways to eliminate them:
- Cigarette lighter fuse (No. 7, 15–20A):
It burns out when connecting powerful devices (for example, car vacuum cleaners or compressors). Solution: Use an outlet in the trunk (if available) or install a power strip with a separate fuse.
- Fog light fuse (No. 15 or No. 16, 10A):
It often fails due to oxidation of the contacts in the headlight unit. Clean the terminals and apply
LIQUI MOLY Kontakt-Spray. - Audio system fuse (No. 10, 15A):
May burn out if there is a short circuit in the speakers or wires. Check the integrity of the insulation of the wiring behind the radio.
If the fuse blows immediately after replacement, don't increase its value - this may cause a fire! In such cases it is necessary:
- 🔍 Test the circuit with a multimeter for a short circuit.
- 🛠️ Check the consumers connected to this circuit (for example, if the headlight fuse burns out, inspect the lamps and connectors).
- 📋 Refer to the electrical diagram X-Trail T31 (attached to the article) to identify the problem area.
If the fuse is burned out, but it is not visible from the outside, use a tester: connect the probes to the fuse contacts in the “dial-up” mode. No signal means a break.
How to properly replace a fuse: step-by-step instructions
Replacing the fuse in Nissan X-Trail T31 - a simple procedure, but requiring accuracy. Follow this algorithm to avoid errors:
- Turn off the ignition and remove the key from the lock. This will prevent a short circuit when removing the fuse.
- Find the faulty fuse according to the diagram (see sections above) or visually (burnt thread inside).
- Remove the fuse with special tweezers (available in the unit) or pliers. Do not use metal objects to avoid damaging the contacts.
- Install a new fuse the same denomination. The use of “bugs” (wire jumpers) is not allowed.
- Check circuit operation. If the fuse is blown again, refer to the Common Problems section.
To replace the fuse links in the engine compartment you will need disconnect the battery terminal (minus). This is a prerequisite, since the inserts are designed for high currents. When installing a new insert, make sure that its contacts fit tightly to the connector - weak contact can cause heating and melting.
⚠️ Attention: On diesel versions X-Trail T31 When replacing fuses in the engine compartment, the fuel system adaptation may be reset. After replacing, let the engine idle for 2-3 minutes to readjust.
Never replace fuses with higher ratings as this may cause wiring damage or fire. If a fuse keeps blowing, look for the cause in the circuit, not the fuse itself.
Additional fuse boxes (behind the glove compartment and in the trunk)
In some trim levels Nissan X-Trail T31 Additional fuse blocks are provided:
- 🧳 Behind the glove compartment - responsible for seat heating, rear 12V socket and sometimes for the system
BDC(mountain descent control). It is accessible after removing the glove compartment (unscrew the 2 screws from the bottom and pull it towards you). - 🚘 In the trunk — found on versions with a third row of seats. The fuses for the rear air conditioning and auxiliary lighting are located here.
Diagram of the additional unit behind the glove compartment:
| № | Denomination (A) | Purpose |
|---|---|---|
| 1 | 20 | Heated front seats |
| 2 | 15 | 12V socket (trunk) |
| 3 | 10 | Rain/light sensor (if installed) |
If your car's heated seats do not work, but the fuse is intact, check heating relay (located next to the block) and the integrity of the wiring under the seats. Often the problem lies in a broken wire due to the constant movement of the chair.

FAQ: Frequently asked questions about fuses Nissan X-Trail T31
Which fuse controls the low beam headlights?
For low beam X-Trail T31 fuse responds No. 11 (10A) in the salon block. If the headlights do not light up after replacing it, check low beam relay (located next to the fuse) and headlight bulbs.
Why does it blow again after replacing the cigarette lighter fuse?
This indicates short circuit in the chain. Common reasons:
- Damaged wiring behind the cigarette lighter (frayed wires).
- A faulty device connected to the outlet (for example, a charger with an internal short circuit).
- Oxidized contacts in the fuse box.
For diagnostics, disconnect all consumers and check the circuit with a multimeter.
Where is the fuel pump fuse located?
The fuel pump fuse is located in engine compartment and has a number F8 (15A). On diesel versions it may be designated as F12 (20A). If the pump does not work after replacing the fuse, check fuel pump relay (it is nearby).
Can fuses from other cars be used?
Yes, but only if they match denomination and type. B X-Trail T31 standard fuses are used mini-blade (small knife ones). Do not install fuses like maxi or ATO - they will not fit in size. Also avoid cheap Chinese analogues: they may have a low-quality metal thread, which will lead to false positives.
How to check the relay in the fuse box?
To check the relay:
- Remove the relay from the block.
- Apply 12V voltage to the contacts
85 (+)And86 (–). - Use a multimeter to check the resistance between
30And87- should be ~0 Ohm.
If there is no resistance, the relay is faulty. You can also replace the relay with a known working one (for example, from a similar circuit).
