Fuse box in Nissan Teana - a key element of the electrical system, on which the operation of the entire car depends: from headlights and radio to security and ignition systems. A faulty fuse can lead to sudden equipment failure, and incorrect replacement can lead to a short circuit or even a fire. In this article we will look at where the fuse boxes are located in Teana J31 (2003–2008) and J32 (2008–2014), how to check them, replace them and avoid common mistakes.

Feature Nissan Teana — the presence of **two main fuse blocks**: one in the cabin (under the dashboard), the other in the engine compartment. In addition, in some configurations there are additional mini-blocks, for example, for the system Intelligent Key or audio systems Bose. We will analyze each of them in detail, provide current diagrams with explanations and explain how to diagnose problems without visiting a service center.

Where is the fuse box located in Nissan Teana?

B Nissan Teana The fuse blocks are located in three zones, and their location depends on the generation and equipment of the vehicle. Let's start with the most accessible one - the **cabin unit**, which is available in all versions.

B Teana J31 (2003–2008) the interior unit is hidden behind a plastic cover **to the left of the steering column**, next to the clutch pedal (for manual transmission) or brake pedal (for automatic transmission). To access it, just:

  1. Open the driver's door.
  2. Press the cover latch (it is located at the bottom of the panel).
  3. Gently pull the cover towards you - it will come off without tools.

B Teana J32 (2008–2014) the design changed slightly: the fuse box was moved **under the glove compartment**, closer to the center console. Here the lid is secured with two latches on the sides. Important: Before removing the cover, turn off the ignition to avoid a short circuit if the contacts are accidentally touched.

The second unit - **under the hood** - is located in the engine compartment, next to the battery. B J31 it is closed with a black plastic cover with the inscription FUSE & RELAY, in J32 - a gray lid with similar markings. The third, additional unit (if equipped) can be located behind the glove box or under the rear seat (in cars with a premium audio system).

Diagram and decoding of fuses Nissan Teana J31 (2003–2008)

In the salon block Teana J31 **30 fuses** and **10 relays** are installed, each of which is responsible for a specific circuit. Below is a table with a breakdown of the most important elements (a complete diagram can be found in the instruction manual or on the unit cover).

Fuse no. Denomination (A) Purpose
1 10 System Intelligent Key, immobilizer
7 15 Audio system, navigation
12 10 Cigarette lighter, 12V socket
18 15 Low beam (left headlight)
25 20 Window lifters

In the engine compartment J31 fuses are located for powerful consumers: radiator fan (40A), ABS system (10A), fuel pump (15A). Please note: The fuel pump fuse often fails when you try to start the car with a dead battery - this is overload protection.

The relays in this block are responsible for:

  • 🔋 Starter (RELAY 1)
  • 💡 High beam (RELAY 3)
  • 🌀 Cooling fan (RELAY 5)
  • 🚗 Main relay of the injection system (RELAY 7)
How to test a relay without a multimeter?

If you suspect a relay malfunction, you can check it “by ear” and “by touch”:

1. When the ignition is turned on, a working relay makes a slight click.

2. If the relay gets warm (hot to the touch), this is a sign of a problem.

3. Try knocking on the relay body - sometimes the contacts “stick” and after a slight blow they begin to work.

Fuse diagram Nissan Teana J32 (2008–2014): changes and features

B Teana J32 The fuse box diagrams have undergone changes due to the updated electrical architecture. For example, separate fuses have appeared for:

  • 📱 Systems Bluetooth and hands-free (FUSE 5, 7.5A)
  • 🎵 Audio amplifier Bose (FUSE 14, 20A)
  • 🔌 120V sockets (in export versions) (FUSE 22, 15A)

In the engine compartment J32 added a relay for the system VDC (stability control), which is often confused with the ABS relay. Important: if after replacing the fuse VDC (10A) the “SLIP” indicator is on on the dashboard, diagnostics of the wheel sensors is required - the fuse itself is rarely to blame.

Another key difference is the fuse. IGN (10A), responsible for the ignition circuits, in J32 moved from the cabin unit to the engine compartment. This is done to simplify access in emergency situations (for example, if the car does not start).

⚠️ Attention: B Teana J32 with the hybrid system (Japanese models) there is an additional high voltage fuse box (120V) under the rear seat. Never touch it without special training - it is life-threatening!

Signs of faulty fuses and relays

How do you understand that the problem is in the fuse and not in the device itself? Here are the typical symptoms:

  • 🚨 Failure of one or more devices (for example, the power windows on one side do not work).
  • 🔥 Burning smell from under the panel or hood - a sign of a blown fuse or melted wiring.
  • 🔄 Spontaneous switching off/on equipment (for example, headlights flashing for no reason).
  • 🛑 The car won't start, but the starter turns - there may be a problem with the fuel pump fuse or the main relay.

If the fuse blows again after replacement, this is a signal of a more serious problem:

  • 🔌 Short circuit in the circuit (often due to damaged wire insulation).
  • 🔋 Consumer fault (for example, the window lift motor is short).
  • ⚡ Power surges in the on-board network (check the generator and battery).
💡

If the fuse is blown, do not rush to install a new one! First, inspect it: if the contacts are melted or blackened, the problem is in the circuit, not in the fuse itself. A temporary solution is to install a fuse with the same rating, but from a “spare” block (for example, from the cigarette lighter, if it is not in use).

How to replace a fuse in a Nissan Teana: step-by-step instructions

Replacing a fuse is a simple operation, but requires care. Here's what you'll need:

  • 🔧 Tweezers (usually included with the machine, on the unit cover).
  • 🔍 Flashlight (to see the markings).
  • 📄 Fuse diagram (you can take a photo from the block cover).
  • 🔋 Spare fuses (set with ratings from 5A to 30A).

Algorithm of actions:

  1. Turn off the ignition and remove the key from the lock.
  2. Remove the fuse box cover (as described above).
  3. Find the faulty fuse using the diagram or visually (a blown fuse has a broken thread inside).
  4. Use tweezers to remove the old fuse and install a new one. same denomination.
  5. Check the operation of the equipment.

Make sure the ignition is turned off|Check the rating of the new fuse (must match!)|Inspect the contacts in the block for oxidation|If the fuse blows again, look for the cause in the circuit-->

If the fuse is stuck and cannot be removed with tweezers, do not use force - this may damage the unit. Instead:

  1. Rock the fuse left and right to loosen the contacts.
  2. Use a flathead screwdriver with an insulated handle, prying the fuse from the side.
  3. If the contacts are oxidized, clean them with alcohol or a special spray (for example, CRC Contact Cleaner).
⚠️ Attention: Never replace a fuse with a “bug” (wire or foil)! This may cause a fire. If you don't have the correct rating on hand, temporarily use a fuse with smaller meaning (for example, instead of 20A put 15A), but replace it with the correct one as soon as possible.

Typical mistakes when working with fuses

Even experienced car owners sometimes make mistakes that lead to serious damage. Here are the most common:

  1. Using the wrong fuse rating. For example, setting 30A instead of 10A may burn the wiring or device.
  2. Replacing the fuse without finding the cause. If the new fuse blows immediately, the problem is in the circuit - ignoring this will lead to repeated replacements or a fire.
  3. Use of force when removing the fuse. This can damage the contacts of the unit, after which you will have to replace the entire module.
  4. Ignoring contact oxidation. Poor contact leads to heating and failure of the fuse.
  5. Working under voltage. Even if you are just checking the fuse, do not do this with the ignition on - there is a risk of a short circuit!

Another common mistake is confusing fuses and relays. Relay is an electromechanical device that closes/opens a circuit upon command, and fuse - This is a protective element that burns out when the current is exceeded. If, for example, the cooling fan does not work, first check the fuse (40A in the engine compartment), and then the relay (RELAY 5).

1. Serviceability of the device itself (for example, a light bulb or motor).

2. Integrity of wiring from the fuse to the consumer.

3. Relay performance (if it is in the circuit).-->

Frequently asked questions about Nissan Teana fuses

🔧 The cigarette lighter fuse constantly blows. What is the reason?

Most often this happens due to:

  • Using powerful devices (such as a car vacuum cleaner or compressor) that exceed the fuse rating (15A).
  • Short circuit in the socket (check the contacts for melting).
  • Malfunctions of the cigarette lighter itself (for example, short circuit of the spiral).

Solution: replace the fuse with a standard one (15A), try connecting the device to a different outlet (if available). If the problem persists, check the wiring.

🚗 The car does not start, the starter does not turn. Is this a fuse?

Most likely the problem is not in the fuse, but in:

  • Discharged battery (check voltage).
  • Faulty starter or solenoid relay.
  • Open circuit between the ignition switch and starter.
  • fuse IGN (10A) or main relay (RELAY 7 in the engine compartment).

First, check to see if the dashboard lights come on when you turn the key. If not, the problem is in the power supply (battery, fuse IGN). If they light up, but the starter does not respond, look for a fault in the starter circuit.

💡 The headlights stopped working. Which fuse should I check?

B Nissan Teana responsible for the light:

  • Low beam: fuses 18 (15A, left headlight) and 19 (15A, right headlight) in the interior block.
  • High beam: fuses 20 And 21 (10A), relay RELAY 3 in the engine compartment.
  • Dimensions: fuse 16 (10A).

If the fuses are good, check the bulbs, relays and wiring. B J32 The light control module may also be faulty (BCM).

🔋 Is it possible to install a fuse of a higher rating?

Absolutely not! The fuse is designed for a certain current, and if you install, for example, 20A instead of 10A, this can lead to:

  • Overheating and melting of wiring.
  • Failure of a device (for example, an audio system or control unit).
  • Fire in the cabin or under the hood.

If a standard fuse often blows, look for the cause (short circuit, faulty consumer), and do not increase the rating!

🛠️ Where to buy fuses for Nissan Teana?

Fuses of standard ratings (5A–30A) are sold:

  • In car dealerships (for example, Autodoc, Exist, IXORA).
  • In online markets (Wildberries, Ozon, AliExpress).
  • Electronics stores (eg. Chip and Dip).

For Teana suitable type fuses ATO/ATC (standard knife ones). For relays it is better to take original ones Nissan or analogues from Hella, Bosch. The average price of a fuse is 10–50 rubles, a relay is 200–800 rubles.
