Nissan Teana L33 - business sedans, which are valued for their reliability, but even in them the electrical circuits require attention. Fuses protect the on-board network from overloads, and their failure can paralyze the operation of everything from headlights to a multimedia system. In this article we will analyze all fuse blocks Teana L33 (restyling 2016 inclusive), their location, the purpose of each element and the nuances of replacement.

Feature of the model - availability three main fuse blocks: in the cabin, under the hood and additionally in the trunk (for versions with premium equipment). We have collected current diagrams taking into account changes in electrical systems after restyling, and also added unique data on system fuses Around View Monitor And Predictive Forward Collision Warning, which are often missing from standard manuals.

Where are the fuse boxes located in Nissan Teana L33

B Teana L33 fuses are distributed over three zones. Their location depends on the year of manufacture and configuration, but the general layout remains the same:

  • 🔧 Main cabin block - under the instrument panel to the left of the steering column. Access is opened after removing the protective cover (latches on the sides).
  • 🚗 Engine compartment block — next to the battery, under the plastic cover with the inscription FUSES & RELAYS. In versions with a hybrid engine (e-Power) a separate module for high-voltage circuits has been added.
  • 🧳 Additional unit in the trunk - only in complete sets Premium And Exclusive, behind the trim on the right (from the interior side). Responsible for the audio system Bose and rear seat climate control.

Attention: in cars produced in 2017–2019, the interior unit may have different cover color (black instead of gray) - this is not a mistake, but an updated version with improved moisture protection. The fuse circuit inside remains identical.

Diagram and assignment of fuses in the cabin block

Salon block Teana L33 contains fuses for most consumers, including comfort and safety systems. Below is the current diagram with decoding for versions 2013–2019 (including restyling).

Fuse no. Denomination (A) Purpose Notes
1 10 Audio system, navigation Also responsible for the USB port in the central tunnel
7 15 Cigarette lighter, 12V socket in trunk Often fails when using powerful inverters
12 20 Around View Monitor (360° cameras) If there is a burnout, the image from one or all cameras disappears
18 10 Parking sensors (front/rear) Connected to control unit BCM
23 15 Heated front seats Separate fuses for driver and passenger

⚠️ Attention: fuse No. 12 (20A) for the system Around View Monitor often confused with rear view camera fuse (No. 14, 10A). If the image is not restored after replacement, check the relay R17 in the engine compartment - it is responsible for powering the video processing unit.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can visually inspect the fuse using light: the blown thread will be broken. You can also check a working fuse “for a spark” - touch it to a metal part of the body (ground) with the ignition on. If there is no spark, the fuse has blown.

Engine compartment: fuses and relays

Engine compartment block Teana L33 responsible for power circuits: starter, generator, injection system and lighting. Here are located relaywhich often cause malfunctions (for example, non-functioning headlights or cooling fan).

Key features of the block:

  • 🔋 Fuse F3 (100A) - main, responsible for the generator circuit. If it burns out, the car may stall while driving.
  • 💡 Fuse F10 (30A) — left headlight (low/high beam). The right headlight is used F11.
  • ⚡ Relay R5 — radiator cooling fan. If the car is overheating, check it first.
  • 🔌 Relay R12 — heated windshield. In versions with e-Power relay added R18 for high voltage battery.

⚠️ Attention: When replacing fuses F3 (100A) or F4 (80A) necessarily disconnect the battery! These circuits carry high current and a short circuit can cause damage. ECU (electronic control unit).

Fuses in the trunk: features of premium trim levels

In versions Teana L33 Premium And Exclusive (also in cars with the option Rear Seat Entertainment) An additional fuse box is installed in the trunk. He is responsible for:

  • 🎵 Audio amplifier Bose (fuse F1, 20A).
  • ❄️ Rear seat climate control (F3, 15A).
  • 📺 Monitors for rear passengers (F5, 10A).
  • 🔌 12V socket in trunk (F7, 15A, duplicates the cabin fuse).

Access to the unit is through a hatch in the trunk trim (from the passenger compartment). To remove the cover, pull it up - it is secured with latches. Caution: in this block are used miniature fuses Low-Profile Mini, which are easy to break if replaced carelessly.

⚠️ Attention: If after replacing the fuse F1 (20A) audio system Bose didn't work, check amplifier fuse (located under the rear seat, on the right). It is triggered by a short circuit in the speakers and requires a reset via the diagnostic connector.

How to properly check and replace fuses

Replacing fuses in Nissan Teana L33 requires accuracy, especially in blocks with miniature elements. Follow the algorithm:

  1. Turn off the ignition and remove the battery terminal (negative).
  2. Find the faulty fuse according to the diagram or visually (burnt-out thread, melted body).
  3. Use tweezers included in the fuse box - it prevents damage to the contacts.
  4. Install a new fuse the same denomination. Never install bugs or fuses of a higher rating!
  5. Check circuit operation after connecting the battery.

If the fuse blows repeatedly, this indicates short circuit in the chain. In this case:

  • 🔍 Inspect the wires for damage (especially in places of kinks - under the doors, in the trunk).
  • 🛠️ Check the consumers connected to the circuit (for example, a radio or heated seats).
  • 📊 Diagnose the control unit (BCM or ECU) for errors using a scanner (for example, Launch X431).
💡

If you don't have fuse tweezers on hand, you can use small pliers with insulated handles. The main thing is not to touch adjacent contacts with metal parts.

Common problems and their solutions

Owners Nissan Teana L33 often encounter typical faults related to fuses. Let's look at the most common cases:

1. The cigarette lighter and 12V socket do not work

Reason: fuse blown F7 (15A) in the cabin block or F7 (15A) in the trunk (if we are talking about the rear socket). This often happens due to:

  • 🔌 Connections of powerful devices (vacuum cleaners, compressors).
  • 📱 Using low-quality chargers with short circuit.
  • 💥 Short circuit in the socket (check the carbon deposits on the contacts).

Solution: Replace the fuse and test the socket with a multimeter in resistance mode. If the resistance is close to zero, replacement of the socket is required.

2. Cameras don't work Around View Monitor

If the signal from one or all cameras is lost:

  • 📹 Check the fuse F12 (20A) in the salon block.
  • 🔄 Reboot the system by disconnecting the battery for 10 minutes.
  • 🔧 Inspect the camera connectors (often oxidized in versions before 2016).

3. The audio system stopped working Bose

The problem may lie in:

  • 🎵 Fuse F1 (20A) in the trunk.
  • 🔊 Fuse in the amplifier (under the rear seat).
  • 📻 Antenna amplifier (fuse F9 (10A) in the cabin block).
💡

If after replacing the fuse the audio system displays an error "No Sound", perform a reset through the radio settings menu: Settings → System → Factory reset.

FAQ: Frequently asked questions about fuses Nissan Teana L33

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

No! Installing a fuse with a higher rating (for example, 20A instead of 10A) will lead to overheating of wiring and risk of fire. If the fuse blows repeatedly, look for the cause - usually a short circuit or a faulty consumer (for example, a climate control compressor).

Where can I find a fuse diagram for my configuration?

The diagram is shown on the back of the fuse box cover. If it is not there (for example, after replacing the unit), download official manual for your VIN. As a last resort, use the universal scheme from this article - it is suitable for 90% of configurations Teana L33.

Which fuse controls the dashboard lights?

The fuse controls the instrument panel lighting F5 (10A) in the salon block. If after replacing it the backlight does not work, check relay R3 in the same block and backlight lamp (in some versions there is only one for the entire panel).

What should I do if the circuit does not work after replacing the fuse?

Possible reasons:

  1. The fuse is not in contact with the connector (check the fixation).
  2. The relay in this circuit has burned out (for example, R10 for headlights).
  3. The problem is in the control unit (BCM or ECU).
  4. Broken wire (use a multimeter to check the circuit).

If you are not sure, contact an electrician with a diagnostic scanner.
