Fuse diagram of <em>Nissan X-Trail T31</em> restyling (2010–2013): where is the block located, decoding and replacement

Owners Nissan X-Trail T31 restyled version (2010–2013) are often faced with the need to check or replace fuses - be it a blown headlight bulb, a non-working cigarette lighter, or a failure of power windows. However, finding an up-to-date fuse block diagram for this modification is not so easy: instruction manuals often provide data for finalized versions, and there is a lot of conflicting information floating around on the Internet.

In this article we have collected exact diagrams and decodings for X-Trail T31 after restyling, including the location of the main and additional units, the purpose of each fuse and relay, as well as practical diagnostic tips. Particular attention was paid to “pitfalls”: for example, why the cigarette lighter fuse may burn out due to a hidden problem in the on-board network, and how to avoid a short circuit when replacing.

The material is based on official data Nissan, supplemented by the experience of car owners and service technicians. All diagrams have been checked for relevance for Russian and European versions T31 with petrol (MR20DD, QR25DE) and diesel (M9R) engines.

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

In the restyled version X-Trail T31 (2010–2013) fuses and relays distributed across three main blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. To open it, pull the tab at the bottom of the panel (no tools required).
• 🔋 Additional block under the hood — located next to the battery, in a plastic box with a lid. On some versions, the cover is secured with a latch that needs to be released with a screwdriver.
• ⚡ Relay block — integrated into the main cabin unit, but some relays (for example, for a cooling fan) may be located separately, under the hood.

Important: on diesel versions (M9R) fuses for the system have been added to the block under the hood AdBlue (if installed) and the high pressure fuel pump. Their location may differ from gasoline modifications.

To avoid confusion, remember a simple rule: all fuses related to comfort (lights, multimedia, power windows) are located in the cabin, and those responsible for “vital” systems (starter, generator, fuel pump) are under the hood. Exception: fuse IGN (ignition) can be duplicated in both blocks.

Diagram and decoding of the cabin unit fuses

Salon block Nissan X-Trail T31 restyling contains 40 fuses And 10 relays. Below is a current diagram with the purpose of each element. Please note: fuse numbers may vary depending on equipment (e.g. versions with xenon added separate fuses for the ignition unit).

Fuse no.	Denomination (A)	Purpose	Notes
1	10	Audio system, navigation	Also protects the USB port and Aux-entrance
7	15	Cigarette lighter	Often burns out when connecting powerful devices (for example, a compressor)
12	10	Light Control Module (BCM)	Responsible for work dimensions And instrument lighting
20	20	Power windows	If it is burnt out, check the motors for jamming
30	10	System ESP/VDC	When replacing, errors must be reset via CONSULT

Important: fuse No. 15 (10A) is responsible for the operation of the tire pressure sensor (TPMS). If the dashboard light comes on after changing a tire, check this fuse first rather than going to a tire shop.

For convenience, below is a visual diagram of the block (clickable if you are reading the article on the website):

Fuses under the hood: diagram and features

Block under the hood Nissan X-Trail T31 restyling contains 20 fuses and 5 relaysresponsible for critical systems. There are a few key points here:

• ⚡ Fuse #5 (30A) protects the generator circuit. If it burns out, check diode bridge And voltage regulator.
• ⛽ Fuse #10 (15A) on diesel versions is responsible for glow plugs. Its failure can simulate problems with the fuel system.
• 🔥 Fuse #15 (40A) - main for the injection system. If it burns out, the engine will not start.

Feature of the block under the hood: fuses here higher denomination (20A to 100A) and replacing them requires care. For example, fuse #20 (80A) protects the chain starter - if it burns out, do not rush to change it. First check:

1. Condition of the battery terminals (oxidation or poor contact).
2. Wiring from the battery to the starter (often rubs against the body).
3. The starter itself checks for shorted windings.

What should I do if the fuse under the hood blows again?

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

1. Disconnect the battery.

2. Remove all consumers from the circuit (for example, if there is a problem with the cigarette lighter fuse, disconnect its connector).

3. Check the wiring for damage (especially in places where there are kinks or body bolts).

4. If you cannot find the reason yourself, contact an auto electrician with Nissan CONSULT for diagnostics.

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Nissan X-Trail T31 It seems like a simple procedure, but there are nuances that will help you avoid mistakes:

1. Turn off the ignition and remove the key from the lock. In some cases (for example, when working with system fuses ESP) you need to disconnect the battery.
2. Use tweezers included with the car — it is designed to withstand pressing force and will not damage the contacts of the unit. Handy tools (pliers, screwdrivers) can deform the sockets.
3. Install a fuse same denomination. Increasing the amperage (for example, from 10A to 15A) will lead to a risk of fire in the wiring.
4. After replacement, check the operation of the system. If the fuse blows again, look for the cause in the circuit (short circuit or increased load).

A mistake many car owners make: ignoring reasons for burnout. For example, if the cigarette lighter fuse blows due to connecting a powerful compressor, the solution is not to install a 20A fuse instead of 15A, but to use splitter with separate fuse or connect the compressor directly to the battery via crocodile clips.

Common problems and their solutions

Some fuses in Nissan X-Trail T31 restyling burns out more often than others. Let's look at typical situations and ways to eliminate them:

1. Cigarette lighter fuse (No. 7, 15A)

Symptoms: The cigarette lighter does not work, the phone does not charge, the DVR does not turn on.

Reasons:

• 🔌 Connecting devices with consumption >10A (for example, car refrigerators).
• 🔥 Short circuit in the cigarette lighter socket (often due to coins or metal objects).
• 🔋 Problems with wiring (frayed wires under the dashboard).

Solution: Before replacing the fuse, inspect the cigarette lighter socket for foreign objects. If the problem persists, check the circuit with a multimeter in test mode.

2. Power window fuse (No. 20, 20A)

Symptoms: The power windows do not work on either the driver or passenger side.

Reasons:

• ❄️ Mechanism jamming (especially in cold weather).
• 🔧 Worn guides or cable in the motor.
• 🔋 Chain overload (for example, when all windows are lifted at the same time).

Solution: Before replacing the fuse, try manually lowering/raising the window (if the mechanism is jammed). If the fuse blows repeatedly, check the motors for a short.

3. System fuse ESP/VDC (No. 30, 10A)

Symptoms: the indicator on the dashboard is on ESP OFF or VDC OFF, the stabilization system does not work.

Reasons:

• 🚗 Damage to angular velocity sensors (for example, after hitting the bumper).
• 🔧 Corrosion of contacts in the block ABS.
• 🔋 Voltage drops in the on-board network.

Solution: Replacing the fuse is only the first step here. After this it is required error reset via a diagnostic scanner (for example, Nissan CONSULT or Launch X431). If the light comes on again, check the sensors and wiring.

Fault diagnosis: when it's not the fuse

If the problem remains after replacing the fuse, it may be something else. Here typical situationswhen the fuse is not at fault:

• 💡 Headlights do not work: check light relay (it may “stick”) and steering column switch. On X-Trail T31 restyling often fails switch combination (article 25560-4M000).
• 🔊 The audio system does not work: except for fuse No. 1, check amplifier fuse (if installed) and antenna cable (the connector often oxidizes).
• 🚪 Central locking or alarm does not work: maybe he's to blame block BCM or actuators in doors. On T31 the weak point is the wiring in the corrugation between the door and the counter.

For diagnostics use multimeter in voltage test mode:

1. Connect the probes to the fuse contacts (supply and load sides).
2. If there is voltage at the input, but not at the output, the fuse has blown.
3. If there is no voltage at the input, there is a problem in the circuit up to the fuse (for example, the relay is faulty or the wiring is damaged).

💡

On Nissan X-Trail T31 There is a restyling in the fuse box under the hood diagnostic connector (white, next to fuse No. 10). Through it you can check the voltage in key circuits without disassembling the panel.

Where to buy fuses for Nissan X-Trail T31

For X-Trail T31 restyling fits standard fuses "Mini Blade" type (for the cabin unit) and «Maxi Blade» (for the block under the hood). You can buy them:

• 🛒 Official dealers Nissan: original fuses (article number 24060-VN700 for dialing). Plus: quality guarantee, minus: the price is 2-3 times higher than the market price.
• 🏬 Auto stores: brands Hella, Bosch, Valeo. The cost of a set (10–15 fuses of different ratings) is from 200 to 500 rubles.
• 🌍 Online stores: Exist.ru, Autodoc, AliExpress (for rare ratings, for example, 80A or 100A).

Tip: Always keep it in your glove compartment. set of spare fuses (10A, 15A, 20A, 25A) and tweezers. On X-Trail T31 Most often the fuses on the 10A And 15A, so there should be more of them.

Please note: on diesel versions (M9R) fuses for the fuel system (#10 And #15 in the block under the hood) should be only original or from trusted brands. Cheap analogues may not withstand inrush currents and melt.

FAQ: Frequently asked questions about fuses Nissan X-Trail T31 restyling

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

No! Increasing the fuse rating may result in wiring fire. If the fuse burns out repeatedly, look for the cause: a short circuit, increased load, or a faulty consumer (for example, a window lift motor).

Where is the fuse for the radio?

In the cabin unit this is a fuse No. 1 (10A). If the radio does not work after replacing, also check the amplifier fuse (if installed) and the circuit ACC (power when the ignition is on).

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

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

1. Are there any foreign metal objects in the socket?
2. Integrity of wire insulation behind the dashboard.
3. Condition of the cigarette lighter connector (contacts often oxidize).

If the problem persists, temporarily disconnect the cigarette lighter plug and use an alternative power source (for example, USB ports in the glove compartment).

Which fuse controls the low beam?

The fuse controls the low beam headlights No. 12 (10A) in the salon block and relay No. 4. If the light does not come on after replacing the fuse, check:

• Lamps (on X-Trail T31 restyling used lamps H7).
• Relay in the cabin unit (may “stick”).
• Light switch on the steering column (a common problem is contact oxidation).

Is it possible to check the fuse yourself without a multimeter?

Yes. Remove the fuse and inspect it under the light: if the thread inside is burned out, it needs to be replaced. You can also use tester made of two batteries and a light bulb (connect the light bulb to the fuse contacts - if it lights up, the fuse is good).
