Where are the fuse boxes located in Nissan Teana J31
B Teana J31 There are two main fuse blocks:
- 🔧 Main unit in the cabin — located to the left of the steering column, behind the protective cover. This is where the fuses for most of the car's electrical circuits are located, including the lighting, audio system and climate control.
- 🚗 Additional block under the hood — installed next to the battery, in a plastic box. High power fuses responsible for the starter, generator and other power circuits are concentrated here.
Also in some configurations may be present third block — it is located in the trunk, next to the audio system amplifier Bose (if provided). This block is responsible for the multimedia system and additional equipment.
To gain access to the cabin unit, simply pull the cover located at the driver’s left foot towards you. It is attached with latches and can be removed without tools. The block under the hood opens after snapping two latches.
- In the salon block
- In the engine compartment
- In the trunk block

Fuse diagram and decoding Nissan Teana J31 (cabin block)
The interior block contains fuses for 7.5A–30A, each of which is responsible for a specific circuit. Below is a table with a breakdown of the most important elements. Please note that numbering may vary slightly depending on the year of manufacture and configuration.
| Number | Ampere (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| 1 | 10 | Body Control Module (BCM) | Power windows and central locking do not work |
| 7 | 15 | Audio system, navigation | The radio does not turn on, there is no sound |
| 10 | 20 | Cigarette lighter | 12V socket does not work |
| 15 | 10 | Low beam (left headlight) | One headlight does not light up in low beam mode |
| 23 | 15 | ABS system | The ABS indicator on the dashboard is on |
The complete diagram can be found on the back of the fuse box cover. If the information you need is not there, download official repair manual for your model.
⚠️ Attention: fuse №23 (15A, ABS) often confused with the stabilization system fuse (VDC). If the ABS light remains on after replacement, also check the relay K27 in the engine compartment.
Engine compartment fuse box: what you need to know
Block under the hood Teana J31 contains fuses and relays responsible for power circuits. Here are the elements on 30A–120A, and their replacement requires special care. For example, fuse 100A is responsible for the generator - if it burns out, the car will not be able to charge the battery.
Key fuses in the engine compartment:
- ⚡ 30A (F1) — Electric power steering (EPS). When it burns out, the steering wheel becomes stiff.
- 🔥 50A (F4) — Main relay of the injection system. If it burns out, the engine will not start.
- 🚨 10A (F10) — Engine control unit (ECU). When there is a malfunction, errors appear
P0600–P0606.
To replace fuses in the engine compartment Be sure to remove the negative terminal from the battery. This will prevent short circuit. Use special tweezers (usually included with the machine) or pliers with insulated handles.
If the fuse in the engine compartment blows out immediately after replacement, do not try to install an element of a higher rating! This may cause the wiring to catch fire. In this case, look for the cause of the short circuit in the circuit.
How to properly replace a fuse: step-by-step instructions
Replacing the fuse in Nissan Teana J31 - a simple procedure, but requiring accuracy. Follow these instructions to avoid errors:
- Turn off the power. Remove the key from the ignition and remove the terminal from the battery (especially for the engine compartment).
- Find the faulty fuse. Visually inspect the elements for burnt threads or melted housing. You can use a tester (multimeter) in dial mode.
- Remove the old fuse. Use the tweezers that came with the car. Do not pull it out with your fingers under any circumstances - this may damage the contacts.
- Install a new fuse. He must be same denomination, as the old one. Make sure the contacts are tight.
☑️ Preparing to replace the fuse
If the fuse blows again after replacement, this indicates short circuit in the chain. In this case, you need to check the wiring for damage or contact a service center for diagnostics.
⚠️ Attention: Never install so-called “bugs” (wire jumpers) instead of a fuse. This may lead to fire in car wiring, especially in high-load circuits (such as starter or alternator).
Frequent problems with fuses in Teana J31 and their solutions
Owners Nissan Teana J31 often encounter typical faults related to fuses. Here are the most common cases and how to resolve them:
- 💡 The cigarette lighter fuse (No. 10, 20A) has blown. The reason is the use of powerful devices (for example, compressors or inverters). Solution: connect energy-intensive devices directly to the battery through a separate fuse.
- 🔊 The audio system does not work (fuse No. 7, 15A). Often, it is not the fuse itself that is to blame, but the oxidation of the contacts in the radio connector. Solution: Clean the contacts with alcohol and check the integrity of the wiring.
- 🚗 The electric power steering fails (fuse F1, 30A in the engine compartment). The problem may be with the relay
K5or malfunction of the EPS-module. Solution: Check the relay and the voltage at the contacts.
If the fuse responsible for BCM (body control unit) burns out regularly, this may indicate a malfunction of the central locking or power windows. In this case, comprehensive diagnostics using a scanner is required. Nissan Consult.
What to do if the fuse is intact, but the device does not work?
If the fuse is good, but, for example, the headlight does not light, check:
1. A light bulb in the headlight (the filament may have burned out).
2. Relay responsible for this circuit (in the cabin or engine compartment).
3. Wiring for breakage or corrosion of contacts.
4. The device itself (for example, the window lift motor may fail mechanically).
Diagnosing faults using a multimeter
If you cannot visually determine a blown fuse, you can use a multimeter. To do this:
- Switch the device to mode
calls(or resistance measurements). - Touch the probes to the fuse contacts. If it is working, the device will show
0 ohm(or beeps). If the fuse is blown, the resistance will tend to infinity.
You can also check the voltage in the circuit with a multimeter. To do this:
- Turn on the ignition.
- Connect black dipstick to a mass (for example, to a car body).
- Red dipstick connect to one of the fuse contacts. If there is voltage (usually
12V), but the device does not work, the problem may be an open circuit after the fuse.
To diagnose the relay, use the same multimeter. Ring the relay coil - the resistance should be within 50–120 Ohm. If the winding is broken, the relay must be replaced.
Before checking fuses with a multimeter, always disconnect the load (for example, turn off the lights or audio system). This will prevent false readings from the device.
FAQ: Frequently asked questions about fuses Nissan Teana J31
Is it possible to install a fuse of a higher rating if it constantly blows?
No, this is extremely dangerous! The fuse is designed for a certain amperage, and if you install an element with a higher rating, this can lead to overheating of wiring and even fire. If the fuse blows repeatedly, look for the cause in the circuit (short circuit, faulty device).
Where to buy fuses for Teana J31?
Fuses of standard ratings (7.5A–30A) are sold in any auto store (for example, Bosch, Hella). The underhood unit may require high-ampere fuses (50A–120A) - it is better to order them using the original number (for example, 28500-JD00A for 100A).
Which fuse controls the alarm?
B Teana J31 The fuse is responsible for the alarm №3 (10A) in the salon block. If it burns out, the car will not respond to the key fob, and the central locking may not work properly. Also check the relay K1 in the same block.
Why did all the devices stop working after replacing the fuse?
Most likely, you installed the wrong fuse or connected the battery terminals incorrectly. Check: 1) Does the new fuse have the same rating as the old one? 2) Is the ground connected correctly? 3) Is there any damage to the fuse box (melted contacts).
Is it possible to repair the fuse (soldering or twisting)?
Absolutely not! The fuse is disposable protective device. Any attempt to restore it (soldering, twisting with wire) violates the design parameters and can lead to a fire. Always use original or certified fuses.
