Nissan Terrano (R51): fuse diagram with decoding and location of blocks

Nissan Terrano (internal designation R51) is a popular crossover released in 2013–2020 based on the platform Renault Dacia Duster. Despite its reliability, even in this car fuses periodically blow, which leads to failure of electrical equipment - from headlights to multimedia system. In the article we will analyze precise diagrams of fuses and relays for all modifications Terrano, including gasoline (1.6, 2.0) and diesel (1.5 dCi) versions.

The main problem of owners is the lack of a single source with up-to-date data. The official repair manual often contains errors or does not take into account changes in electrical circuits after the 2017 restyling. We have collected verified schemes taking into account all modifications, including export versions for the markets of Russia, Europe and the Middle East. You will also learn how to correctly diagnose a malfunction and avoid common mistakes when replacing.

Where are the fuse boxes in the Nissan Terrano?

B Nissan Terrano R51 provided three main fuse and relay blocks, as well as additional fuse links in high power circuits. Their location depends on the year of manufacture and configuration, but in 90% of cases the diagrams are identical.

Main installation locations:

• 🔧 Main unit in the cabin - under the instrument panel on the driver's side. Access is gained by removing the cover (latch or two screws).
• 🚗 Block under the hood - next to the battery, in a plastic box with a lid (sometimes marked as Fusible Link Box).
• ⚡ Additional relay block — behind the glove compartment or under the center console (in versions with climate control).

On diesel Terrano 1.5 dCi there may be a fourth block - injection system fuseslocated next to the high pressure fuel pump. It is often confused with a glow plug relay, but their purposes are different.

Fuse diagram in the interior block (2013–2020)

The interior unit is the most popular, as it is responsible for lighting, multimedia, windows and comfort system. Below is the current diagram for all versions Terrano R51, including restyled models after 2017.

Please note: fuse numbers may be duplicated in different modifications, but they are nominal (amperage) and purpose remain unchanged. For example, fuse F27 (10A) is always responsible for the cigarette lighter, regardless of the market.

Number	Rating (A)	Purpose	Notes
F1	10	Engine control unit (ECU)	On diesel versions - 20A
F7	10	Side lights (left side)	If burnt out, check the lamps and wiring
F15	15	Audio system, navigation	Also responsible for the USB port
F27	15	Cigarette lighter, 12V socket	Often burns out when using powerful devices
F30	30	Window lifters	If there is a failure, check the relay K5

The complete diagram of the cabin unit can be downloaded from FAQ section (link to PDF file). If your fuse is not listed in the table, check additional relay block — some circuits (for example, heated seats) are protected separately.

⚠️ Attention: In Middle Eastern versions, the fuse F10 (7.5A) is responsible for stabilization system (ESP). In European and Russian modifications, this circuit is protected by a fuse F18 (10A).

Fuse box under the hood: decoding and nuances

Engine compartment (Fusible Link Box) contains high rating fuse links (from 30A to 120A), as well as relays of the main systems. Its location depends on the type of engine:

• 🔥 On petrol Terrano — to the right of the battery, under a plastic cover.
• ⛽ On diesel engines - to the left of the battery, next to the air intake.

The peculiarity of this block is the presence fuse inserts (fusable links), which look like insulated wires. They cannot be replaced with standard blade fuses! Below are the key elements:

Designation	Rating (A)	Purpose	Type
FL1	80	Main power circuit	Fuse link
F40	30	Cooling fan	Standard fuse
R1	—	Starter relay	Relay
FL5	50	Injection system (diesel)	Fuse link

When replacing fuse links, use only original Nissan parts (article 24040-3M200 for FL1). Chinese analogues often have a reduced wire cross-section, which leads to melting of the contacts.

How to check and replace a fuse: step-by-step instructions

Diagnosis of fuses in Nissan Terrano does not require special skills, but there are nuances that will help you avoid mistakes. For example, You can't test the fuse for a spark. - this can damage the electronic components of the car.

Algorithm of actions:

1. Turn off the ignition and remove the negative terminal from the battery (required for units under the hood!).
2. Using a flathead screwdriver or your fingers, remove the unit cover (in the interior unit, the latches are located on the sides).
3. Visually inspect the fuses: burnt out will have a burnt or broken conductor inside.
4. For an accurate check, use a multimeter in “continuity” mode or a voltage tester.

If the fuse is blown, replace it with a new one same denomination. Installing a high ampere fuse may result in fire in the wiring! For example, replacement F27 (15A) on 20A is fraught with melting of the cigarette lighter socket.

Prepare a new fuse (value checked!)|

Check the circuit for short circuit after replacement -->

⚠️ Attention: B Terrano with the system Start/Stop (optional for European markets) fuse F35 (15A) is responsible for the automatic start module. Replacing it requires resetting errors via a diagnostic scanner (for example, Launch X431).

Common problems and their causes

According to service center statistics, in Nissan Terrano R51 Most often the fuses of the following circuits fail:

• 🔌 F27 (15A) - cigarette lighter. Reason: connecting devices with a power >180 W (for example, car vacuum cleaners).
• 💡 F10 (7.5A) — ABS/ESP. Cause: corrosion of wheel sensor contacts or damage to the harness under the fender.
• 🔊 F15 (15A) — audio system. Cause: Short circuit in the speakers or USB connector.
• 🚪 F30 (30A) — power windows. Reason: freezing of the mechanism or wear of the guides.

If the fuse blows again after replacement, it is necessary to look for the reason, and not increase its denomination. Typical culprits:

• 🔋 Damaged wiring insulation (especially in places where thresholds are crossed).
• 💦 Corrosion in connectors (for example, in the headlight control unit).
• 🔧 Faulty consumers (for example, a short circuit in the window lift motor).

For diagnostics use wiring diagram (can be found in the repair manual Renault Duster, since the platform is identical). For example, the cigarette lighter circuit passes through a relay K12, which is located in the cabin block.

How to find a short circuit without instruments?

Disconnect all consumers in the circuit (for example, remove the lamps from the headlights when checking the fuse F7).

Replace the fuse and turn on the circuit. If it does not burn out, connect the consumers one by one until you find the culprit.

For circuits with constant consumption (for example, alarms), use the elimination method: disconnect one connector at a time, checking the fuse.

Differences in the schemes before and after the 2017 restyling

In 2017 Nissan Terrano underwent restyling, which affected not only the exterior, but also the electrical part. Main changes:

• 🔄 A fuse has appeared in the cabin unit F38 (10A) for keyless entry (in pre-restyle versions this chain was protected F19).
• 📱 Multimedia system fuse (F15) became 20A instead of 15A (due to adding support Apple CarPlay/Android Auto).
• ⚡ A relay appeared in the engine compartment K20 for automatic braking systems (optional for European markets).

The markings of the fusible links under the hood have also changed:

• In pre-restyle versions, the insert FL3 (50A) was responsible for generator.
• After 2017 it was replaced by FL4 (60A), and FL3 began to defend stabilization system.

If you have Terrano 2017–2020, be sure to check with VIN-specific scheme. For example, in vehicles with the option 360° camera fuse added F42 (10A), which is not included in the basic configurations.

FAQ: Frequently asked questions about Nissan Terrano fuses

Where can I download the complete fuse diagram in PDF?

The complete diagram for your modification can be downloaded from this link (the archive includes versions for gasoline and diesel engines, as well as before/after restyling). Pay attention to the section VIN-specific notes — features for specific markets are indicated there.

Why after replacing the fuse F10 does the ABS light come on?

This indicates malfunction in the wheel sensor circuit or ABS control unit. fuse F10 protects only the power circuit, and the error itself can be caused by:

• Damage to the wiring to the sensors (often chafing near the hub).
• Corrosion on the connectors of the ABS unit (located under the hood, next to the vacuum booster).
• Malfunction of the unit itself (requires diagnostics with a scanner).

Before replacing the unit, check sensor resistance (should be ~1 kOhm).

Can fuses from Renault Duster be used?

Yes, Nissan Terrano R51 And Renault Duster (first generation) have identical fuse blocks, since they are built on the same platform. However, there are nuances:

• B Duster fuse F25 (10A) is responsible for fog lights, and in Terrano - for glove compartment lighting.
• In diesel versions Duster 1.5 dCi fuse link FL5 has a face value 60A, and in Terrano — 50A.

We recommend checking with VIN number car when purchasing spare parts.

How to reset ESP error after replacing fuse?

If after replacing the fuse F10 or F18 icon on the dashboard is lit ESP OFF, follow these steps:

1. Turn on the ignition (without starting the engine).
2. Press and hold the button ESP OFF (located on the center console) for 10 seconds.
3. Turn off the ignition, wait 30 seconds and start the engine.

If the error remains, diagnostics with a scanner is required (for example, error C1130 indicates a malfunction of the rotation angle sensor).
