<em>Nissan Terrano</em> fuse diagram: location, purpose and replacement

Nissan Terrano is a popular crossover that is valued for its reliability and unpretentiousness. However, even in such a car, electrical problems periodically arise: the cigarette lighter stops working, the headlights fail, or the heater fan does not turn on. In 90% of cases, the culprit is a blown fuse. But where to look for it? Which one is responsible for this or that circuit? And how to replace it correctly without causing a short circuit?

In this article you will find complete fuse box diagrams for Nissan Terrano different generations (including restyled versions), an explanation of each element indicating the current strength, as well as step-by-step instructions for diagnosis and replacement. We'll sort it out unique pitfallsproblems that owners of this particular model face - for example, why the cigarette lighter fuse often burns due to the connection of non-standard gadgets or how to distinguish the original unit from a fake.

Where is the fuse box located in Nissan Terrano?

B Terrano (like most cars Nissan-Renault) provided two main fuse boxes:

• 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. To gain access, you need to turn the three latches counterclockwise.
• ⚡ Additional block under the hood — located next to the battery, in a plastic box with the inscription FUSE BOX. The lid is secured with two latches.

On some versions Terrano (for example, with a diesel engine K9K) may be present third mini-block — it is hidden under the glove compartment and is responsible for the injection system circuits. Its availability depends on the configuration and year of manufacture (more often found on cars from 2017–2020).

Important: on restyled models (after 2020), the location of the blocks has not changed, but fuse ratings for some circuits they were increased - for example, for heated seats from 15A to 20A. This is due to the addition of new options (wireless charging, additional USB ports).

Fuse diagram of the cabin unit: decoding by circuit

The interior unit contains fuses for most consumers that owners encounter on a daily basis: lighting, multimedia, power windows. Below is the current diagram for Nissan Terrano all generations (differences are indicated in the notes).

Fuse no.	Denomination (A)	Purpose of the circuit	Notes
F1	10	Body Control Module (BCM)	On restyling - 15A
F7	20	Cigarette lighter / 12V socket	Often lights up when connecting compressors or inverters
F12	15	Audio system, navigation	On versions with Bose — 20A
F18	25	Heated rear window	Check the contacts on the connectors!
F23	10	Parking sensors (parking sensors)	On diesel versions - F24

⚠️ Attention: fuse F30 (30A) responsible for the work electric power steering (EPS). If it burns out, the steering wheel becomes “stiff” and the icon lights up on the dashboard EPS FAULT. Never replace it with a bug! This can lead to failure of the amplifier control unit (repair cost - from 20,000 rubles).

Fuse box under the hood: what is protected there?

The engine compartment unit is responsible for power electrics: starter, generator, cooling fans, fuel pump. Fuses of increased rating (up to 100A) are used here, and replacing them requires caution - if done incorrectly, you can burn the main relay or even the engine control unit (ECU).

Features of the engine compartment Terrano:

• 🔥 Fuse F1 (100A) — the main one, connects the battery with the rest of the on-board network. Don't touch it unless absolutely necessary!
• ⚡ F5 (30A) — cooling fan circuit. If it burns out, the engine overheats, but the error message does not always appear on the panel.
• ⛽ F12 (15A) — fuel pump. If it fails, the car will not start (you cannot hear the pump running when you turn the key).

⚠️ Attention: On diesel Terrano with engine K9K There is a fuse in the engine compartment F20 (20A)responsible for glow plugs. If it burns out, the car has difficulty starting “when cold”, and the spiral icon lights up on the dashboard. Do not confuse this with the pump fuse!

To diagnose the engine compartment you will need a multimeter. Verification algorithm:

1. Disconnect the negative battery.
2. Remove the unit cover by pressing the latches.
3. Turn on the ignition (without starting the engine).
4. Test the circuits for voltage (there should be 12V at the fuse input).

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

Replacing a fuse seems like a simple procedure, but... Nissan Terrano There are nuances that are not written about in the manuals. For example, why may the cigarette lighter stop working after replacing the fuse? on-board computer or why a new fuse blows immediately after installation.

Step-by-step algorithm:

1. Identify the faulty circuit. If the radio stops working, look for the fuse. F12. Window lifters do not work - check F20 (25A).
2. Find the fuse in the diagram. Use the tables above or the interactive map.
3. Remove the old fuse. To do this, use plastic tweezers (included with the machine). Never pull out the fuse with metal tools!
4. Check integrity. A blown fuse has a broken filament inside. Sometimes a break can be seen with the naked eye, but it is better to check with a multimeter in “continuity” mode.
5. Install a new fuse. He must be same denomination! Installing a larger fuse (for example, 20A instead of 15A) may result in a fire.

⚠️ Attention: If after replacement the fuse burns out again, do not repeat the procedure - This is a sign of a short circuit in the circuit. Common reasons for Terrano:

• 🔌 Moisture getting into the cigarette lighter connector (especially if you use it to charge your phone during the rain).
• 🎵 Short circuit in the speakers (if the audio system fuse burns out when turning on music).
• 🚗 Damage to the wiring in the doors (if there is a problem with the power window fuse).

What should I do if the fuse blows again?

If a fuse blows immediately after replacement, first turn off all consumers in that circuit. For example, for a cigarette lighter, remove all devices from the 12V socket. Then check the circuit with a multimeter for short circuit. If the problem persists, contact an auto electrician to diagnose the wiring. In 30% of cases, the culprit is a frayed wire in the corrugation under the threshold.

Typical problems with fuses in Nissan Terrano and their solutions

Terrano — a reliable car, but it has “diseases” associated with electrics. Here are the most common problems that owners encounter:

1. The cigarette lighter fuse blows once a month

Reason: In 80% of cases, non-standard devices are to blame - tire compressors, 12V→220V inverters or cheap phone chargers. They create current surges that the standard fuse (20A) is not designed to handle.

Solution:

• 🔌 Use a power strip with its own fuse (e.g. Blitz or Hella).
• 📱 Use original USB adapter to charge phones Nissan (article 28512-JM00A).
• 🔧 Install an additional relay on the cigarette lighter circuit (the diagram is in application).

2. The rear window heating fuse blows

Reason: Oxidation of contacts on glass connectors or damage to conductive threads. B Terrano The left side of the glass often suffers - moisture accumulates there due to the poor location of the drainage holes.

Solution:

• 🧹 Clean the contacts with sandpaper (600-800 grit).
• 🔧 Check the integrity of the threads with a multimeter (resistance should be 2-5 Ohms).
• 💧 Process contacts WD-40 or special lubricant for electrical contacts (Liqui Moly Electronic-Spray).

3. Audio fuse blows when playing music

Reason: Short circuit in the speakers (especially in the rear ones, where the wires often fray) or failure of the amplifier (on versions with Bose).

Solution:

• 🔊 Turn off the speakers one by one to find the faulty one.
• 🎵 Check the amplifier circuit (fuse F15 in the cabin block).
• 🔧 If the problem is in the amplifier, contact the service (self-repair is difficult due to soldered contacts).

Where to buy fuses for Nissan Terrano: original vs analogues

Fuses are consumables, but even here there are nuances. B Terrano recommended to use original fuses Nissan (series 28512-...), as they have improved contacts and precise current calibration. However, there are worthy analogues on the market.

Type	Original (item)	Analogues	Price (for 1 piece), rub.
Mini fuse (ATO/ATC)	28512-JM00A (set)	Hella 8EA 002 131-011, Bosch 1 987 462 937	50–120
Maxi fuse (under the hood)	28512-4M00A	Littlefuse MEGA 297, Eaton Bussmann MGA	200–400
Audio fuse	28512-3M00A (20A)	Blue Sea 5191 (for systems with Bose)	150–300

⚠️ Attention: Avoid cheap fuses without markings (for example, “no-name” ones from Chinese online stores). They often have a low thread cross-section, which leads to false positives. In the worst case, such a fuse may do not burn out in case of short circuit, which will cause the wiring to melt.

Where to buy:

• 🏬 Official dealers Nissan — guarantee of original spare parts, but the price is 30–50% higher.
• 🛒 Specialty stores (AutoSpetsCenter, EuroAuto) - there are certified analogues.
• 🌍 Online ( Exist.ru, AutoDoc) - convenient for searching for rare denominations (for example, 25A or 40A).

Frequently asked questions (FAQ)

Is it possible to replace the fuse with a higher rating (for example, 15A instead of 10A)?

Absolutely not! The fuse is designed for a certain current, and increasing it can lead to melted wiring or even a fire. If a fuse frequently blows, look for the cause (short circuit, faulty consumer), rather than increasing the rating.

Which fuse controls the low beam headlights? Terrano?

The fuse controls the low beam F9 (10A) in the salon block. However, if the lamps do not light, also check the relay K7 (located in the same place) and the chain is broken.

Why did the glove compartment light stop working after replacing the cigarette lighter fuse?

B Terrano The cigarette lighter circuit and the glove compartment light are sometimes combined through one fuse (F7). If after replacement the backlight does not work, check the light bulb in the glove compartment (often it simply burns out) or the contacts in the connector.

Where is the fuse for the fuel pump?

Fuel pump fuse - F12 (15A) in the engine compartment. If it burns out, the car will not start (the pump will not be heard when the ignition is turned on). Before replacing, also check the pump relay (K5).

Is it possible to use a “bug” (homemade fuse) in an emergency?

Use bugs (wires, foil) extremely dangerous! B Terrano this often leads to melted fuse box connectors or even a fire. If you urgently need to get to the service, use a fuse of a similar rating (for example, 10A instead of 15A), but do not exceed it!
