Owners Nissan X-Trail third generation (body T32, 2014-2020) sooner or later face the need to check or replace fuses. A car's electrical circuits are protected by dozens of fusible links, and without an exact diagram of their location, fault diagnosis becomes a guessing game. In this article you will find detailed description of all fuses and relays for X-Trail T32, including the location of mounting blocks, element ratings and their purpose.
Feature T32 — availability two main fuse blocks: one in the cabin (under the dashboard), the second in the engine compartment. We will analyze both, indicate which circuits each fuse protects, and give unique recommendations for diagnosing typical problems - for example, why the cigarette lighter may not work or why the stabilization system fails ESP with a blown fuse F37. You will also learn how to properly remove the relay without damaging the contacts and what tools you will need for this.
Where are the fuse boxes located in the Nissan X-Trail T32
B X-Trail T32 There are three zones for placing fuses and relays, but for most tasks two main ones are sufficient:
- 🔧 Salon block — located under the dashboard on the driver's side. To gain access, you need to open the cover by prying it with a flat-head screwdriver or a plastic spatula at the bottom (next to the clutch/brake pedal).
- 🚗 Engine compartment block — located in the engine compartment, next to the battery. The cover is fixed with two latches and removed upwards.
- ⚡ Additional relay block — in some trim levels it is installed behind the glove compartment (the plastic lining must be removed).
Important: in diesel versions X-Trail T32 (engine R9M) the diagram of the engine compartment may differ - fuses for the injection system have been added Common Rail and glow plugs. We will indicate these nuances in the appropriate sections.
⚠️ Attention: Before working with fuses, be sure to turn off the ignition and remove the battery terminal (negative). B X-Trail T32 Some circuits remain energized even when the ignition is turned off, which can lead to a short circuit!

Interior fuse box: decoding and diagram
Cabin mounting block X-Trail T32 contains 40 fuses And 12 relays. Below is a table with the purpose of each element, relevant for most configurations (2014-2020). Please note: fuses F21 And F22 may not be available in basic versions without system Bose.
| Designation | Denomination (A) | Purpose | Notes |
|---|---|---|---|
F1 |
10 | Engine management system (ECU) |
During combustion, the engine may not start or may not work properly. |
F10 |
15 | Cigarette lighter, 12V socket (rear) | Often fails when connecting powerful devices (for example, compressors) |
F20 |
10 | Control unit ABS/ESP |
When combustion occurs, the indicator lights up ABS on the dashboard |
F37 |
15 | Multimedia system (NissanConnect) |
Responsible for the operation of the screen, navigation and rear view camera |
R5 |
— | Heated rear window relay | If there is a malfunction, also check the fuse F30 |
To replace fuses in the interior block, use plastic tweezers, which is usually attached to the inside of the lid. If you don't have tweezers, you can carefully remove the fuse with small pliers, but don't put in too much effort — the contacts in the block are fragile.
If after replacement the fuse burns out again, do not rush to install an element of a higher rating! This may cause the wiring to catch fire. First check the circuit for short circuit using a multimeter.
Engine compartment: high power fuses and relays
Engine compartment block Nissan X-Trail T32 is responsible for electrical power section: starter, generator, cooling fans, headlights, etc. Fuses of increased rating are installed here (up to 100A) and relays with reinforced contacts. The block cover is usually marked with a diagram, but the inscriptions are erased over time.
Key elements of the engine compartment:
- 🔋
F101(80A) - main fuse for the generator circuit. If it burns out, the car may stall while driving. - 💡
F105(30A) - low/high beam fuse (left headlight). If it burns out frequently, check the lamps for proper wattage. - ❄️
R103— radiator cooling fan relay. If there is a malfunction, the engine will overheat. - 🔥
F110(50A) - circuit fuseABS(only for diesel versions).
Feature X-Trail T32 with diesel engine R9M: fuses are added in the engine compartment F115 (30A) for glow plugs and F116 (20A) for valve EGR. If your car doesn't start well when cold, check these elements first.
⚠️ Attention: FusesF101AndF102(100A) in the engine compartment do not have standard fuse links — they are made in the form of bolted connections. To replace them you will need special fuse insert with holes for bolts (sold in auto electricians).
Disconnect the battery (negative terminal first)
Clean the block cover from dirt (use a brush)
Check for moisture inside the unit
Prepare a new fuse of the same rating
Have a multimeter handy to test the circuit -->
How to check and replace a fuse: step-by-step instructions
Algorithm for checking fuses in Nissan X-Trail T32 no different from other cars, but there are nuances associated with the design of the blocks. Here step by step instructions taking into account the features of the model:
Determine which fuse is responsible for the faulty circuit (use the diagrams from the previous sections).
Turn off the power: for the interior unit, just turn off the ignition; for the engine compartment, remove the battery terminal.
Remove the fuse with tweezers. Look it up to the light: burnt thread or a melted body is a sign of a malfunction.
Check the circuit with a multimeter:
- 🔌 Set resistance test mode (
Ω). - 🔍 Touch the fuse contacts with the probes. There must be resistance
0 ohm(or close to zero). - 💥 If the device shows
OL(break), the fuse is blown.
- 🔌 Set resistance test mode (
Install a new fuse same denomination. Using a fuse with a large amperage is fraught with fire!
If the new fuse blows immediately, don't try to put the next one - This is a sign of a short circuit in the circuit. In this case you need:
- Check the wiring from the fuse to the consumer (for example, to the cigarette lighter or headlight).
- Check the serviceability of the consumer itself (for example, a light bulb or fan motor).
- Inspect the wiring harnesses for chafing or melted insulation.
What to do if the fuse appears intact, but the circuit does not work?
Sometimes the fuse contacts oxidize, and despite visual integrity, current does not pass. In this case:
1. Remove the fuse and clean its contacts with an eraser or fine sandpaper.
2. Check the voltage at the unit sockets (should be ~12V when the ignition is on).
3. If there is no voltage, the problem is in the unit itself or in the wiring to it.
Typical problems with fuses in X-Trail T32 and their solutions
Owners Nissan X-Trail T32 often encounter repeated faults related to fuses. Here most common cases and ways to eliminate them:
- 🔌 Cigarette lighter doesn't work:
The culprit is the fuse.
F10(15A) orF11(20A, for rear socket). It often burns out due to the connection of powerful devices (for example, car vacuum cleaners). Solution: Replace the fuse and use splitter with protection or connect devices via battery. - 🚨 Alarm doesn't work:
Check the fuse
F25(10A) and relayR10. If the problem persists, inspect the wires under the hood - they often fray near the fuse box. - 🎵 Multimedia system (
NissanConnect) does not turn on:The fuse is responsible
F37(15A). If replacement does not help, check the relayR12and connectors behind the radio - they can oxidize. - ❄️ Heated rear window does not work:
fuse
F30(20A) and relayR5. Also check rear door wiring — the veins there often break due to constant opening.
Unique nuance X-Trail T32: in vehicles with the system ProPilot (adaptive cruise control) fuse added F40 (10A) for radar. If it burns out, the system generates an error "Front Radar Obstruction" even with a clean sensor.
If the fuses of one circuit (for example, the cigarette lighter or headlights) are frequently blown in your X-Trail T32, the problem lies not in the fuses themselves, but in circuit overload or short circuit. In this case, wiring diagnostics are required, rather than replacing fuse links.
Relay in Nissan X-Trail T32: purpose and verification
Relay in X-Trail T32 are responsible for turning on powerful consumers: fans, fuel pump, headlights, etc. Unlike fuses, they not disposable, but over time they can fail due to burning of contacts or wear of the winding. Below is a list of the main relays and symptoms of their malfunction:
| Designation | Purpose | Symptoms of a problem |
|---|---|---|
R1 |
Fuel pump relay | The engine does not start or stalls after a few seconds |
R3 |
Cooling Fan Relay (Low Speed) | The engine overheats in traffic jams |
R8 |
Starter relay | When you turn the key you hear clicks, but the starter does not turn |
R10 |
Alarm relay | The alarm is not armed or goes off spontaneously |
To check the relay, remove it from the block and inspect the contacts for melting or oxidation. For an accurate diagnosis:
- Connect the multimeter in mode
Ωto conclusions85And86(winding). There must be resistance50-120 Ohm. - Serve
12Vto these terminals (possibly from a battery). You should hear a click - this means that the relay is working properly. - Check the resistance between
30And87(contacts). In the off state -OL, included -0 ohm.
If the relay does not click or the winding resistance is equal 0/OL, it needs to be replaced. For X-Trail T32 Fits standard size relays ISO 280 (you can buy universal ones, for example, Bosch or Hella).
Frequently asked questions about Nissan X-Trail T32 fuses
Is it possible to install a fuse of a higher rating if the standard one is constantly on?
No! An increase in denomination will lead to overheating of wiring and risk of fire. If the fuse frequently blows, look for the cause: a short circuit, a faulty consumer (for example, a stove motor) or a circuit overload (for example, a compressor in the cigarette lighter that is too powerful).
Where can I find a fuse diagram for my X-Trail T32 configuration?
The exact diagram can be found:
- On the back of the fuse box cover (sometimes erased).
- B instruction manual (section "Electrical equipment").
- On the website Nissan TechInfo (registration required).
- In thematic groups of owners X-Trail T32 (for example, on Drive2 or X-Trail Club).
Which fuse controls the heated seats?
For heated seats in X-Trail T32 fuse responds F28 (20A) in the cabin unit. If heating does not work, also check:
- Relay
R9(in the salon block). - Wiring under the seats - wires often fray.
- Power button (contacts may oxidize).
Why after replacing the fuse F101 (80A) does it burn again?
fuse F101 protects the generator circuit. If it burns out again, possible reasons:
- Defective generator (diode bridge breakdown).
- Short circuit in power cable from the generator to the battery.
- Defective voltage regulator (battery recharge).
To diagnose, disconnect the generator and check the circuit with a multimeter. If the fuse does not light, the problem is in the generator.
Where is the central locking fuse located?
B X-Trail T32 The fuse controls the central locking F23 (10A) in the cabin block. If the locks do not work, also check:
- Relay
R7(in the salon block). - fuse
F15(7.5A) - responsible for the body control unit (BCM). - Battery - Low voltage may cause locks to fail to operate.
