Owners Nissan Terrano 2 (internal designation R20) sooner or later they face the need to check or replace fuses. These small but critical elements protect the vehicle's electrical circuits from overloads and short circuits. Without them, even a minor short circuit could destroy expensive electronics - from headlights to the engine control unit.

Unlike previous generations Terrano, the second generation (produced from 2014 to 2022) received a more complex electrical architecture, which was also reflected in the number of fuses. In this guide you will find current fuse block diagrams for all modifications, including diesel and gasoline versions, as well as step-by-step instructions for replacing them. Particular attention is paid common diagnostic errors, which can lead to repeated burnout of the elements.

Where are the fuse boxes located in Nissan Terrano 2?

B Terrano 2 There are two main fuse blocks, as well as an additional relay module. Their location depends on the configuration and year of manufacture, but in most cases the diagrams are unified:

  • 🔧 Main unit in the cabin — located to the left of the steering column, under the plastic cover. To gain access, simply open the driver's door and remove the protective panel.
  • 🚗 Additional block under the hood — located next to the battery, in a plastic box with a lid. In some versions (for example, with a diesel engine K9K) high power fuses are located here.
  • ⚡ Relay block — often combined with the main cabin unit, but in top trim levels (Tekna) can be taken out separately.

It is important to consider that in restyled versions Terrano 2 (after 2018) location of fuses behind parking assistance system And rear view camera has been changed. If your car was manufactured later than 2018, check the diagram on the inside of the block cover - there should be current markings there.

  • Only in case of malfunctions
  • Once a year for prevention
  • Never checked
  • I don't know where they are

Diagram and decoding of the cabin unit fuses

Cabin fuse box Nissan Terrano 2 contains elements responsible for most electricity consumers. Below is a table with the assignment of each fuse for the petrol engine version HR16DE (1.6 l). For diesel modifications (K9K) schemes may differ - see. section about diesel versions.

Fuse no. Denomination (A) Purpose
F1 10 Engine management system (ECU), immobilizer
F5 15 Low beam (left headlight), daytime running lights (DRL)
F10 20 Power windows (all doors), electric mirrors
F14 10 Audio system, navigation (NissanConnect), USB port
F20 15 Rear fog lamp, license plate light

Please note: fuse F12 (7.5 A) responsible for the work parking sensors And rear view cameras. If it burns out again after replacement, the cause may be damaged wiring in the rear bumper or corrosion in the camera connector. In this case, diagnostics with a multimeter is required.

💡

Before replacing a fuse, always turn off the ignition and remove the negative terminal from the battery. This will prevent a short circuit when installing a new element.

Features of fuses in diesel versions Terrano 2

Diesel modifications Nissan Terrano 2 with engine K9K (1.5 dCi) have several key differences in the fuse circuit:

  • 🔥 Fuse F25 (30 A) is responsible for glow plugs and their control relays. Its burnout is often accompanied by an error P0380 on the dashboard.
  • ⚡ Fuse F30 (20 A) protects the chain turbocharger and valve EGR. If it fails, the engine may go into emergency mode.
  • 🚘 A fuse has been added to the block under the hood F40 (50 A) for high pressure fuel pump (HPFP).

Owners of diesel versions should pay attention to fuse F18 (10 A)which protects the circuit fuel pressure sensor. Its burnout can lead to difficulty starting the engine, especially in cold weather. If the fuse burns out repeatedly, it is necessary to check the integrity of the wiring from the sensor to the engine control unit (ECU).

What should I do if the fuse blows again?

If the new fuse blows immediately after installation, this indicates a short circuit in the circuit. In this case:

1. Disconnect all consumers connected to this fuse (for example, disconnect the headlight connector if there are problems with F5).

2. Check the circuit with a multimeter in “continuity” mode for a short to ground.

3. Inspect the wiring for melted insulation or signs of oxidation in the connectors.

4. If the problem is not found, contact an electrician to diagnose the control unit (the transistor inside may be faulty ECU).

Step-by-step instructions for replacing fuses

Replacing the fuse in Nissan Terrano 2 does not require special skills, but it is important to follow the algorithm to avoid mistakes. Below are step-by-step instructions taking into account the features of the model:

  1. Preparation: Turn off the ignition and remove the negative terminal from the battery. This will prevent accidental shorting.
  2. Block access:
    • For salon unit: Press the cover latch (located at the bottom) and pull it towards you.
    • For block under the hood: Press out the two plastic clips on the sides of the cover.
  • Removing the fuse: Use special tweezers (usually attached to the block cover). If it is not there, you can carefully pry the fuse off with a small screwdriver.
  • Check: Inspect the fuse under the light - the burnt thread will be visible. You can also check it with a multimeter in the “diagnosis” mode.
  • Installing a new: Insert a fuse of the same rating. Never use high amperage fuses - this may cause a fire!

    • Make sure the ignition is turned off

    Remove the negative terminal from the battery

    Check the rating of the new fuse (must match the old one)

    Use tweezers to remove (not your fingers!)

    Ring the circuit after replacement (if the fuse has blown again)

    -->

    If the fuse blows again after replacement, this indicates short circuit or increased load in the chain. In this case, diagnostics using a multimeter or contacting service is required. For example, a common cause of a blown fuse F10 (20 A) — a jammed window lift motor, which creates excessive load.

    💡

    Using a fuse with a higher rating (for example, 20 A instead of 10 A) can lead to melted wiring and even a fire. Always install fuses strictly according to the diagram!

    Common problems and their solutions

    Some faults in Nissan Terrano 2 directly connected to fuses. Below are typical symptoms and how to resolve them:

    • 💡 Low beam headlights do not work: Check the fuse F5 (15 A) and relay K9 in the salon block. If the fuse is good, inspect the lamps and connectors for oxidation.
    • 🔊 Audio system doesn't work: The culprit is often the fuse F14 (10 A). Also check the connector ISO radios - in Terrano 2 it is prone to oxidation.
    • 🚪 Power windows don't work: The problem may be in the fuse F10 (20 A) or in the power window control unit (located in the driver's door).
    • 🔋 The engine does not start, the starter does not turn: Check the fuse F3 (10 A) in the block under the hood and the starter relay. On diesel versions also inspect the fuse F40 (50 A) for the fuel pump.

    Particular attention should be paid fuse F22 (10 A)who is responsible for stabilization system (ESP). Its burnout may be accompanied by the icon lighting up ESP OFF on the dashboard. In this case, it is also recommended to check the angular velocity sensors on the wheels - their malfunction can cause increased load on the chain.

    ⚠️ Attention: If after replacing the fuse F1 (10 A) (responsible for ECU) the engine is unstable or errors have appeared, it is necessary to reset the control unit adaptations. To do this, disconnect the battery for 10–15 minutes or use a diagnostic scanner (for example, Launch X431).

    How to check a fuse without a multimeter?

    If you don't have a multimeter at hand, check the fuse in Nissan Terrano 2 can be done visually or using a simple diagram:

    1. Visual inspection: Take out the fuse and look at the light. A burnt thread will be torn or melted. Some fuses have an indicator - if it turns black, the element is faulty.
    2. Checking for spark (for advanced users only!):
      • Turn on the ignition.
      • Carefully touch the fuse terminals with a metal object (for example, a screwdriver).
      • If there is a spark, the fuse is good. Be careful - this method may damage the chain!
  • Replacing with a known good one: Take a fuse of the same rating from another circuit (for example, a cigarette lighter) and install it in the place of the one being tested. If the device works, the problem is in the fuse.

    • For more accurate diagnostics, you can assemble a simple circuit with a light bulb:

    

    [Аккумулятор 12В]
    

    |
    

    [Лампочка 5Вт]
    

    |
    

    [Предохранитель]
    

    |
    

    [Масса]

    If the light comes on when connected, the fuse is good. This method is suitable for testing fuses up to 20 A.

    Tips for extending fuse life

    Fuses in Nissan Terrano 2 can last for years if you follow a few simple rules:

    • 🔌 Avoid overload: Do not connect devices with a consumption of more than 10 A (for example, powerful compressors or inverters) to the cigarette lighter. Cigarette lighter fuse (F16, 15 A) is not designed for such loads.
    • 💧 Protect electrical equipment from moisture: After washing, check whether water has entered the fuse box under the hood. Moisture can cause contact corrosion and short circuits.
    • 🔧 Clean your contacts regularly: Once a year, remove the fuses and clean their contacts with alcohol. This will prevent oxidation and overheating.
    • ⚡ Keep an eye on your battery: Low voltage in the on-board network (less than 11.5 V) can cause increased current in the circuits, which leads to blown fuses. Check the battery charge, especially in winter.

    If you often experience blown fuses, you should pay attention to the quality of the elements themselves. Cheap fuses from unknown brands may have inaccurate ratings or poor contacts. It is recommended to use original fuses Nissan (article 28500-JD00A) or high-quality analogues from Bosch or Hella.

    ⚠️ Attention: B Nissan Terrano 2 with the system NissanConnect fuse F14 (10 A) protects not only the audio system, but also the module Bluetooth. If after replacing the fuse the connection with the phone is not restored, you may need to reset the multimedia system settings through the menu Settings → System → Reset.
