Nissan Teana J31 — a reliable business-class sedan, but even in it the electrical circuits require attention. Fuses protect the on-board network from overloads, and their failure can paralyze the operation of headlights, power windows, or even the engine. In this article we will look at where the fuse boxes are located in Teane J31, how to check and replace them correctly, and also provide a complete explanation of the circuit diagrams for various modifications (including versions with 2.5L V6 And 3.5L V6).
Feature J31 — distribution of fuses across several blocks: the main one in the cabin, an additional one under the hood, and even separate fuse links in high-power circuits. We will show you how to avoid typical diagnostic mistakes (for example, confusing fuses with relays) and tell you what symptoms indicate a breakdown of a particular element. If your lights go out or your power windows fail, here you will find the exact algorithm of actions.
Where are the fuse boxes located in Nissan Teana J31
B Teane J31 fuses and relays are distributed over three main zones. Their location depends on the year of manufacture and configuration, but the general layout remains the same:
- 🚗 Main unit in the cabin - to the left of the steering column, behind the plastic cover. The fuses for most consumers are concentrated here (lights, audio system, climate control).
- 🔧 Block under the hood — next to the battery, in a plastic box. Responsible for high current circuits: starter, generator, cooling fans.
- ⚡ Additional fuse links - in the engine compartment, next to the relay box. Often ignored during diagnosis, but can cause malfunctions (for example, fuel pump failure).
On models with 3.5L V6 (VQ35DE) The unit under the hood may have additional relays for the engine management system. In versions with 2.5L V6 (VQ25DE) The circuit is simplified, but the location of the fuses remains the same. To get to the interior unit, you will need to unclip two latches on the lid (tread carefully - the plastic is fragile!).
⚠️ Attention: On right-hand drive cars (for example, Japanese versions), the block in the cabin may be mirrored. Before replacing, check the markings on the cover!
Explanation of fuses Teana J31: scheme and purpose
Below is a table with the assignment of fuses for main cabin unit (valid for most modifications 2008–2013). Ratings are in amperes (A). Please note: In some markets (eg USA or Japan) the schemes may vary!
| Fuse no. | Rating (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| 1 | 10 | Engine control system (ECU), immobilizer | The engine does not start, the immobilizer indicator is flashing |
| 7 | 15 | Cigarette lighter, 12V socket | Charging devices does not work, cigarette lighter is burned out |
| 12 | 20 | Electric windows (all 4 doors) | The window does not go up/down, you can hear the relay clicking |
| 18 | 10 | Audio system, navigation, multimedia screen | The radio does not turn on, no sound, black screen |
| 25 | 15 | Low beam (left headlight) | One headlight does not light, the lamp burns out when turned on |
Important: Fuse No. 25 (low beam) is often confused with No. 26 (right headlight). If after replacement the lamp burns out again, check the circuit for a short circuit or oxidation of the contacts in the headlight.
For the unit under the hood, the key fuses are:
- 🔋 30A — Main relay of the injection system (if it fails, the engine stalls 2-3 seconds after starting).
- 💡 40A — Cooling fans (if both fans do not work, check this fuse and relay
K17). - ⚡ 100A — Generator (fuse link, when it burns out, the battery indicator on the dashboard lights up).
- Cabin (cigarette lighter, power windows)
- Engine compartment (fans, generator)
- Never had a problem
- Another option
How to check the fuse in Teana J31: step by step instructions
Checking fuses does not require special tools, but it is important to do it correctly. Here is the algorithm of actions:
- Turn off the ignition and remove the negative terminal from the battery (especially if you are checking the unit under the hood).
- Remove the fuse tweezers (usually included with the block). Do not use metal objects - there is a risk of shorting the contacts!
- Visual inspection: A blown fuse has a broken filament inside. Sometimes the body melts or turns black.
- Checking with a multimeter (dialing mode):
- Touch the probes to the fuse contacts.
- Beep or resistance
0 ohm- the fuse is OK. - No signal - break.
☑️ What you need to check fuses
If the fuse is blown, do not replace it with a higher denomination - this may lead to a fire in the wiring. For example, instead of 10A can't bet 15A, even if it “burns out too often.” In this case, look for the cause - a short circuit or overload in the circuit.
⚠️ Attention: On Teana J31 with the system Intelligent Key (keyless entry) fuse No. 5 (10A) is responsible for the operation of the key. If, after replacing the battery in the key, the car does not respond to a signal, check this fuse and perform the synchronization procedure (see the instructions for the car).
Typical faults and their causes
Owners Teans J31 often encounter recurring problems with fuses. Here are the most common cases:
- 🔌 The cigarette lighter fuse blows (No. 7, 15A) - usually due to the use of powerful devices (for example, car vacuum cleaners or compressors). Solution: Use a protected power strip or connect devices directly to the battery.
- 💡 Frequent low beam fuse blows (No. 25/26, 15A) — check the lamps (perhaps they are installed too powerful) and the contacts in the headlight for oxidation. On models with xenon, the problem may be in the ignition unit.
- 🚪 Power windows do not work (fuse No. 12, 20A) — if after replacing the fuse the problem remains, check the motors and wiring in the doors (wires in the corrugation often fray).
- 🔊 The audio system does not turn on (fuse No. 18, 10A) - on versions with Bose The amplifier may be at fault. Before replacing the fuse, turn off the radio for 10 minutes (reset).
If the fuse burns out immediately after replacement, there is short circuit. For diagnostics:
- Disconnect all consumers in this circuit (for example, if it is a cigarette lighter fuse, disconnect all devices).
- Replace the fuse and turn on the ignition. If it burns out again, the problem is in the wiring.
- Check the circuit with a multimeter in resistance mode (should be >10 kOhm between positive and ground).
If there are traces of melting or burning in the fuse block, do not limit yourself to replacing the burnt element. Clean the contacts with alcohol and check the fuse for tightness (poor contact causes heating).
Replacing fuses: nuances and errors
Replacing a fuse seems like a simple procedure, but even here there are pitfalls. Let's look at the key points:
- 🔧 Use only original fuses or high-quality analogues (for example, Littlefuse, Bussmann). Cheap Chinese fuses may have a low thread cross-section, which will lead to false alarms.
- 📋 Refer to the diagram on the unit cover - on some modifications Teana J31 The location of the fuses has changed. For example, on restyled versions (2011–2013) the cigarette lighter fuse may be No. 9 instead of No. 7.
- 🔄 Do not replace the fuse by eye. - even if it looks intact, check it with a multimeter. Sometimes the thread remains visually intact, but has microcracks.
Mistakes that owners make:
- Using "bugs" (homemade wire jumpers). This may cause a fire! If there is no suitable fuse, temporarily disconnect the consumer (for example, do not use the cigarette lighter) and buy a new fuse.
- Replacing a fuse without finding the cause. If it burns out, there is a problem in the circuit. Ignoring this will lead to repeated failure.
- Relay confusion. There are relays on the block under the hood next to the fuses. They look similar, but not interchangeable! The relay has a metal case and contacts under the legs, and the fuse has a plastic case with a visible thread.
What to do if the fuse melts the plastic of the block?
If the fuse gets so hot that it melts the block body, this is a sign of a serious overload. In this case:
1. Replace the entire fuse box (original part number: 28550-4M000).
2. Check the circuit for short circuit (especially if it is a high current fuse, such as 40A for fans).
3. Make sure the fuse rating is correct (sometimes previous owners installed larger fuse ratings).
Safety fuses: ABS, airbags, immobilizer
Particular attention should be paid to fuses responsible for security systems. Their failure can make the car uncontrollable or block the engine from starting. B Teana J31 these include:
| Fuse no. | Rating (A) | System | Consequences of a malfunction |
|---|---|---|---|
| 3 | 10 | ABS, ESP | The ABS and ESP indicators on the dashboard light up, the brakes work without the assistance of the systems |
| 5 | 10 | Immobilizer, keyless entry system | The engine does not start, the key is not recognized, the immobilizer indicator is flashing |
| 10 | 10 | Airbags (SRS) | The indicator lights up SRS AIRBAG, airbags may not deploy in an accident |
If the fuse is blown №10 (SRS), don't ignore the problem! Airbags may not deploy in an emergency. After replacing the fuse, be sure to reset the error using a diagnostic scanner (for example, Launch X431 or ELM327 with the program Nissan DataScan).
For systems ABS/ESP (fuse No. 3) false alarms are typical in wet weather. If the indicators light up periodically, check the wheel sensor connectors for oxidation and clean them WD-40.
⚠️ Attention: On Teana J31 with the system Around View Monitor (all-round view) fuse No. 19 (10A) is responsible for the cameras. If the cameras turn off after washing or rain, check this fuse and the tightness of the camera connectors (water often gets in).

Never buy fuses labeled "Fuse" without the rating or brand. Such products are often made from low-quality materials and can cause a fire.
FAQ: Frequently asked questions about fuses Teana J31
Is it possible to use a larger fuse if it blows frequently?
No! Increasing the rating will lead to overheating of the wiring and the risk of fire. If the fuse burns out repeatedly, look for the cause: a short circuit, a faulty consumer (for example, a window lift motor) or a circuit overload (for example, the compressor in the cigarette lighter is too powerful).
Which fuse controls the radio in Teana J31?
The fuse controls the audio system №18 (10A) in the salon block. If after replacement the radio does not turn on, also check the fuse №1 (10A) (power supply to the ECU affects the CAN bus to which the radio is connected). On versions with Bose Additionally, check the amplifier fuse (located next to the amplifier in the trunk).
Why does it blow again after replacing the cigarette lighter fuse?
The reasons may be as follows:
- Using devices with consumption >10A (for example, a car refrigerator). Solution: connect powerful devices directly to the battery through a fuse.
- Short circuit in the cigarette lighter socket. Check the contacts for melting or metal objects.
- Malfunction of the cigarette lighter itself (for example, the coil is shorted). Replace the cigarette lighter (part number:
25460-4M000).
Where is the fuel pump fuse located in Teana J31?
Fuel pump fuse - №20 (15A) in the salon block. If the pump does not work after replacement, also check:
- Fuel pump relay (
K5in the block under the hood). - Fuse link in the pump circuit (located next to the relay block under the hood, rated
15A). - Power to the pump (the pink wire on the pump connector should have +12V when the ignition is turned on).
⚠️ Attention: If the pump fuse burns out immediately after replacement, do not try to start the car again. This may result in engine control unit (ECU) failure.
How to reset the airbag error after replacing the fuse?
After replacing the fuse №10 (SRS) The error on the dashboard will not go away on its own. To reset you will need:
- Connect a diagnostic scanner (for example, Launch CReader or ELM327 with the program Nissan Consult).
- Go to section
SRS/Airbagand erase mistakes. - If the error appears again, check the airbag circuit for an open or short circuit (often the problem is in the connectors under the seats).
It is impossible to reset the error without a scanner - it is stored in the unit’s memory SRS.
