Nissan Terrano fuse diagram: where the blocks are located, decoding and replacement

Nissan Terrano is a reliable crossover, but even it is not immune to electrical faults. If your headlights, windshield wipers or cigarette lighter stop working, the first thing you should check is fuses. In this article we will look at where the fuse boxes are located in Terrano (including models R51 and restyled versions), how to decipher them and replace them without contacting the service.

The vehicle's electrical circuit is protected by several fuse and relay blocks. Their location depends on the year of manufacture and configuration, but the general logic remains unchanged. We have collected current data on block arrangement, fuse ratings and typical problems that owners face. You will also learn how to correctly diagnose a fault and avoid short circuits when replacing.

Where are the fuse boxes in the Nissan Terrano?

B Nissan Terrano fuses are distributed over three main blocks:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. Fuses for most consumers are concentrated here: lighting, climate control, audio systems.
• 🔋 Block under the hood — located next to the battery (in models with gasoline engines) or in a special compartment (in diesel versions). Responsible for power circuits: starter, generator, fans.
• 🚗 Additional unit in the trunk - not available in all trim levels. Most often, fuses for the rear lights, heated rear window and 12V socket are located here.

The exact location may vary slightly depending on the year of manufacture. For example, in Terrano R51 until 2014, the main cabin block was covered with a decorative panel with latches, and in restyled versions (2015+) the cover is fixed with one screw. Under the hood fuse box for diesel engines Terrano with engine K9K moved closer to the windshield to avoid moisture penetration.

To get to the interior unit, just pull the plastic cover towards you (it is held on by clips). To access the unit under the hood, you will need to disconnect the battery terminal - this is a mandatory safety requirement!

Interpretation of fuses in the cabin block

The cabin unit is the most popular for diagnostics. It contains fuses for lighting, multimedia And comfort systems. Below is a table with the purpose and ratings for Nissan Terrano R51 (2014–2020). Please note: the color of the fuse depends on its rating (for example, 10A is red, 15A is blue).

Number	Denomination (A)	Purpose	Notes
F1	10	Side light bulbs (left side)	If burnt out, also check the relay K1
F5	15	Cigarette lighter, 12V socket in the cabin	Often fails when connecting powerful devices
F10	7.5	Climate control unit	In the event of a malfunction, the temperature settings are reset
F14	10	Audio system, navigation	Also responsible for illuminating the buttons on the steering wheel
F20	20	Windshield wipers, windshield washer	If shorted, the washer motor may burn out.

Important: in models with a system NissanConnect audio system fuse (F14) has a rating of 15A, and not 10A, as in the basic configurations. If the fuse blows again after replacement, this indicates a short circuit in the circuit. In this case, wiring diagnostics is required.

To check the fuse, use a multimeter in continuity mode or visually inspect it for a broken thread. If the fuse is intact, but the device does not work (for example, the headlights do not light), check the corresponding relay - it may stick or fail.

Fuse box under the hood: features and diagram

Block under the hood (Power Distribution Box) is responsible for power circuits car. Here are the fuses and relays for:

• ⚡ Starter and generator
• 🔥 Engine cooling fans
• 💡 Main relay of the injection system (for gasoline versions)
• 🔋 Battery (fuse 120A)

In diesel Terrano with engine K9K The fuse is also located here 30A for high pressure fuel pump control unit (HPFP). Its failure may make it impossible to start the engine.

To get to the block:

1. Open the hood and remove the negative terminal from the battery.
2. Press the latches of the unit cover (it is black, with a logo Nissan).
3. To remove fuses, use special tweezers (usually attached to the inside of the cover).

⚠️ Attention: Never replace fuses under the hood with bugs (jumper wires). This can cause wiring fires, especially in the starter or generator circuits where the current reaches 100A and above.

If after replacing the fuse under the hood the problem persists (for example, the starter does not turn), check:

• 🔋 Condition of the battery terminals (oxidation or weak contact).
• 🔌 Integrity of wires from the block to the starter.
• 🛠️ Operability of the starter relay (in the cabin unit, position K7).

What should I do if the fuse blows again?

If the new fuse blows immediately, there is a short circuit in the circuit. Algorithm of actions:

1. Disconnect all consumers connected to this circuit (for example, if it is a cigarette lighter fuse, disconnect the chargers).

2. Check the wiring for insulation damage or melting (especially at kinks).

3. If there are no visual defects, use a multimeter in resistance test mode: disconnect the connectors of the circuit and test it for a short circuit.

4. In 80% of cases, the problem lies in a melted connector or a damaged wire near the consumer (for example, in the washer motor or socket block).

Fuses for diesel and petrol versions: key differences

Fuse diagrams in Nissan Terrano with petrol (MR20DE) and diesel (K9K, R9M) engines have several critical differences. This is due to the different architecture of injection, turbocharging and particulate filter regeneration systems (DPF).

Main differences:

System	Petrol Terrano	Diesel Terrano
Fuel pump	fuse F25 (15A) in the salon block	fuse F30 (30A) under the hood + relay K12
Turbine/intercooler	Absent (in atmospheric versions)	fuse F18 (20A) for wastegate valve
Diesel Particulate Filter (DPF)	—	fuse F22 (10A) for pressure sensors
Glow plugs	—	Relay K9 + fuse F15 (50A) under the hood

In diesel versions, pay special attention to the fuse F15 (50A) — he is responsible for the glow plug chain. If it fails, the engine will have difficulty starting when cold, and the indicator will light up on the dashboard Check Engine with an error P0380 (malfunction of the glow circuit).

In gasoline Terrano most often problems arise with the fuse F25 (15A)which protects the fuel pump. If the car does not start, but the starter turns, first check this fuse and relay K8 in the salon block.

How to properly replace a fuse: step-by-step instructions

Replacing the fuse in Nissan Terrano - a simple procedure, but requiring accuracy. Follow this algorithm to avoid errors:

1. Turn off the power. Turn off the ignition and remove the negative terminal from the battery. This will prevent a short circuit when removing the fuse.
2. Find the faulty fuse. Use the diagram from the instruction manual or the table above. Visually inspect the fuse - a burnt-out thread will be visible to the naked eye.
3. Remove the fuse. Take the plastic tweezers from the fuse box (usually located on the inside of the cover) and carefully pull out the fuse. Do not use metal tools!
4. Check the circuit. If the fuse is blown, check the circuit for a short circuit before installing a new one (see spoiler above).
5. Install a new fuse. Use fuse same denomination. Installing a fuse with a larger rating may cause the wiring to melt.
6. Check the system operation. Connect the battery and turn on the ignition. Make sure the faulty unit is working.

⚠️ Attention: If the fuse blows again after replacement, do not attempt to repeat the procedure. This indicates a serious fault in the circuit (for example, a short in the wiring harness or failure of the consumer). In this case, diagnostics by an electrician is required.

For convenience, keep a set of spare fuses of different ratings in the glove compartment. B Nissan Terrano Most often the fuses on the 10A, 15A And 20A, so it’s worth having them in reserve.

Typical problems and their solutions

Owners Nissan Terrano often encounter repeated faults related to fuses. Let's look at the most common cases and ways to eliminate them.

1. The cigarette lighter or 12V socket does not work.

• 🔌 Check the fuse F5 (15A) in the salon block.
• 🔍 Inspect the outlet connector for melting or oxidation of contacts.
• 📱 If the problem occurs when connecting a specific device (for example, a DVR), try another one - perhaps the first one consumes too much current.

2. Headlights or side lights do not light up.

• 💡 Check fuses F1 (10A) And F2 (10A) for the left and right sides respectively.
• 🔦 If the fuses are intact, but the headlights do not work, check the lamps and relays K1 (lighting).
• 🔧 In diesel versions also check the fuse F17 (10A) — he is responsible for the light control unit (BCM).

3. Windshield wipers do not work.

• 🌧️ Check the fuse F20 (20A) and relay K5 in the salon block.
• 🔧 If the fuse is intact, but the wipers do not move, check the washer motor (often jammed due to corrosion).
• 💧 In winter, the problem may be frozen washer fluid - warm up the reservoir with a hairdryer.

4. The engine does not start (the starter does not turn).

• 🔋 Check the fuse F30 (30A) under the hood (starter power circuits).
• 🔑 If the relay does not click when you turn the key, check the fuse F25 (15A) (gasoline) or F15 (50A) (diesel).
• 🔧 Make sure the battery terminals are clean and tight.

If none of the above methods help, the problem may lie in a malfunction ECU (electronic control unit) or broken wiring. In this case, it is recommended to conduct computer diagnostics.

FAQ: Frequently asked questions about Nissan Terrano fuses

Can I use fuses of a different rating if I don’t have the right one on hand?

No, this is strictly prohibited. The fuse is designed for a certain current, and installing an element with a higher rating can lead to melted wiring or even a fire. If you urgently need to get to the store, you can temporarily use a fuse with smaller nominal (for example, instead of 15A put 10A), but only for a short time.

Why does the cigarette lighter fuse burn out when connecting the DVR?

This occurs due to exceeding the permissible current. Most sockets are 12V Terrano designed for 10–15A (120–180 W). If the DVR consumes more (for example, with two cameras and a screen), the fuse will blow. Solutions:

• Use a power strip with overload protection.
• Connect the recorder directly to the battery via a fuse.
• Replace the outlet with a more powerful one (for example, 20A).

Where can I find the fuse diagram for my version of Terrano?

The fuse diagram depends on the year of manufacture and configuration. You will find exact information:

• B instruction manual (section "Electrical equipment").
• On back of the fuse box cover (there is often a diagram there).
• On specialized forums (for example, Nissan Club Russia or Drive2).

If you have Terrano 2017 and newer, the circuit may differ from earlier models due to updated electrics (for example, a separate fuse has appeared for the rear view camera).

What to do if the fuse is intact, but the device does not work?

In this case, the problem lies not in the fuse, but in:

• Relay - check the corresponding relay in the block (for example, K1 for lighting).
• Wiring — test the circuit with a multimeter to check for a break.
• Consumer - for example, if the headlights do not light, check the lamps and their connectors.
• Control unit - in modern Terrano many functions are controlled ECU or BCM.

If you are not confident in your abilities, it is better to contact an auto electrician with a diagnostic scanner.

Is it possible to repair the fuse (soldering or twisting)?

Absolutely not. The fuse is disposable protective device, designed to operate when the current is exceeded. Any attempt to “restore” it (by soldering, twisting or winding foil) will lead to:

• Lack of circuit overload protection.
• Risk of wiring melting.
• Fire in case of short circuit.

The cost of a fuse is scanty (from 10 rubles), and the consequences of its “repair” can cost thousands.
