Owners Nissan Terrano It's not uncommon for 2017 models to need to check or replace fuses—whether due to an electrical failure, a short circuit, or routine maintenance. However, finding an up-to-date fuse box diagram for this model can be difficult: information in the owner's manual is often scattered across different sections, and online resources offer outdated information for other model years.

In this article we have collected complete fuse and relay diagram for Nissan Terrano 2017 model year, including them location in the cabin and under the hood, the purpose of each element, as well as step-by-step instructions for diagnosis and replacement. We paid special attention differences in trim levels with gasoline (2.0 l) and diesel (1.6 l) engines, which are often ignored in standard manuals.

Where are the fuse boxes located in Nissan Terrano 2017

B Terrano 2017 provided three main fuse boxes:

  • 🚗 Main unit in the cabin — located to the left of the steering column, behind the decorative cover. Access to it opens by turning three clamps.
  • 🔧 Engine compartment block — located next to the battery (driver's side). The lid is secured with two latches.
  • ⚡ Additional relay block — in some trim levels it is installed under the glove compartment (removing the bottom panel is required).

Important: in diesel versions Terrano with engine K9K 1.6 dCi the engine compartment may have additional relays for the injection system, which are not available in gasoline versions. This is due to the operating features of the high pressure fuel pump (HPFP) and valve EGR.

📊 Where do your fuses blow out most often?
  • In the salon block
  • In the engine compartment
  • In the relay block
  • Haven't encountered it
  • I find it difficult to answer

Before you start replacing, make sure that the problem is in the fuse: check contact status (oxidation or scorching can simulate a malfunction) and circuit voltage multimeter. In 30% of cases, the cause of non-functioning electronics is not the fuse, but poor contact in connectors or corrosion on the terminals.

Interior block fuse diagram

Salon block Nissan Terrano 2017 contains fuses for most comfort and control systems. Below is a table with the purpose of each element (the numbers correspond to the designations on the block cover).

Number Ampere Purpose Notes
F1 10A Engine management system (ECU) Errors may occur during burnout P0600-P0606
F7 15A Audio system, navigation Also responsible for the USB port and Bluetooth-module
F12 20A Cigarette lighter, 12V socket Often burns out when using powerful inverters
F18 10A Sensors ABS And ESP If there is a malfunction, the indicator lights up VSA on the dashboard
F23 15A Interior and trunk lighting Turns on lamps in doorways

⚠️ Attention: fuse F12 (20A) - one of the most vulnerable in Terrano 2017. When connecting devices with power over 180W (for example, car vacuum cleaners) it burns out in 80% of cases. We recommend using splitter with protection or connect the equipment directly to the battery through an additional fuse.

Remove the unit cover (turn the 3 latches counterclockwise)

Find the fuse by number from the table (use the tweezers included in the kit)

Visually inspect the filament (if broken, replace it)

Check the voltage at the contacts with a multimeter (should be ~12V)

Install a new fuse of the same rating -->

If the fuse blows again after replacement, this indicates short circuit in the circuit. In such cases, it is necessary to check the wiring in the area from the unit to the consumer. For example, for a fuse F7 (audio system) A common cause is damage to the insulation of the wires under the driver's seat (the harness to the speakers runs there).

Underhood fuse and relay box

Engine compartment block Nissan Terrano 2017 is responsible for power part of electrical equipment: starter, generator, ignition system and main relays. Its location depends on the type of engine:

  • 🔥 Petrol versions (HR16DE, MR20DD): the unit is located to the right of the battery, under a plastic cover with the inscription FUSE & RELAY.
  • ☁️ Diesel versions (K9K 1.6 dCi): the unit is moved closer to the windshield and has additional relays for EGR and glow plugs.

A feature of the engine compartment block is the presence mini relay (for example, for a cooling fan or fuel pump), which look similar to fuses, but have a different operating principle. Their verification requires calls tester or replacement with a known good element.

Designation Type Purpose Symptoms of a problem
R1 Relay Main relay (Main Relay) Failure of all electrical appliances, engine will not start
F3 Fuse 30A Electric cooling fan Engine overheats, fan does not work
R5 Relay Fuel pump (petrol)/Glow plugs (diesel) The engine does not start or runs intermittently
F8 Fuse 40A ABS/ESP (power) Indicators are on ABS And VSA, the brakes work without electronic assistance

⚠️ Attention: When replacing a relay R5 in diesel versions Terrano use only original parts Nissan 28450-4M015 or analogues from Bosch with catalog number 0 332 014 150. Cheap Chinese relays often cannot withstand the load and lead to burnout of tracks on the control unit board.

💡

If after replacing the fuse F3 (30A) The cooling fan does not turn on, check the temperature sensor (located on the thermostat). Its malfunction is a common cause of false protection activations.

Differences in the fuse diagram for different configurations

Nissan Terrano 2017 was produced in several trim levels, which influenced the presence of certain fuses:

  • 🎵 Comfort: no fuse for rear parking sensors (F15), but there is a separate slot for connection.
  • 🚙 Elegance: added fuse F19 (10A) for rear view camera and light/rain sensors.
  • 🔥 Tekna (diesel): reinforced fuses for the injection system (F25 20A instead of 15A in petrol versions).

Available with xenon headlights (Tekna) an additional relay appears in the engine compartment R9 for the ignition unit. Its failure leads to flickering or failure of one of the headlights. The problem can be diagnosed by the characteristic crackling when the light is turned on.

How to determine the equipment of your Terrano?

Open the glove compartment and look for the VIN sticker (starts with XNB...).

First 3 characters after XNB indicate the configuration:

- T32 — Comfort (basic)

- T33 — Elegance (medium)

- T34 — Tekna (top)

You can also identify the package by the availability of options: for example, only in Tekna There is a heated steering wheel and memory for the seats.

If you have installed additional equipment (for example, radar detector or hardwired dvr), its fuse can be added to a free slot in the interior unit. In this case be sure to use a fuse with a rating 20-30% higher than the rated oneto avoid false alarms during peak loads.

Step-by-step instructions for replacing fuses

Replacing the fuse in Nissan Terrano 2017 requires a minimum set of tools: pliers with insulated handles, multimeter (optional) and tweezers (usually included with the machine). Follow the algorithm:

  1. Turn off the ignition and remove the negative terminal from the battery (especially important when working with the engine compartment).

  2. Find the faulty fuse according to the diagram (see sections above) and remove it with tweezers. Do not use metal tools - they may damage the contacts of the unit.

  3. Check the circuit with a multimeter: connect the probes to the contacts of the fuse socket. When the ignition is on, the voltage should be ~12V. No voltage indicates a wiring break.

  4. Install a new fuse same denomination. Using a high amperage fuse may result in fire in the wiring!

  5. Check the operation of the equipment. If the fuse blows again, look for a short circuit (see tips below).

⚠️ Attention: B Nissan Terrano 2017 fuse F1 (10A, ECU) responsible for powering the engine control unit. When replacing it do not touch contacts with bare hands - static electricity can damage microcircuits ECU. Use an antistatic wrist strap or at least touch a metal part of the body before working.

💡

Never replace a fuse with a “bug” (wire or foil)! B Terrano 2017 this may cause the unit to fail BCM (Body Control Module), the cost of which exceeds 50,000 rubles.

Short circuit diagnostics: practical tips

If the fuse blows repeatedly, there is a short circuit in the circuit. To search for it in Nissan Terrano 2017 follow the method "half division":

  1. Disconnect all consumers connected to this fuse (for example, for F12 - cigarette lighter and socket).

  2. Install a new fuse. If it does not burn out, connect the consumers one by one until you find the problem one.

  3. If the fuse blows immediately, look for a short in the wiring. Use the multimeter in mode calls:

    • Disconnect both ends of the wire being tested.
    • Connect one probe to the wire, the other to ground. If there is a signal, the wire is shorted to the housing.

Typical fault locations in Terrano 2017:

  • 🔌 Wiring harness under gas pedal — rubs against the bracket.
  • 🚪 Wiring in doorways - break when opened/closed frequently.
  • 💡 Trunk light — contacts oxidize due to moisture.

To test the relay use replacement method: Temporarily install a known-good relay from a different slot (for example, the fan relay and defroster relay are often interchangeable). If the problem disappears, buy a new relay.

Common mistakes when working with fuses

Even experienced car owners make mistakes that can lead to serious damage. Here are the most common:

  • 🔥 Using the wrong fuse rating - for example, installation 20A instead of 10A for ECU. This may burn the tracks on the control unit board.
  • 🛠️ Replacing the fuse without disconnecting the battery - in circuits with high inductance (for example, a cooling fan) this is fraught surge voltage.
  • 📱 Ignoring contact oxidation - even a new fuse will not work if the contacts in the block are covered with a green coating (copper oxidation).

⚠️ Attention: B Nissan Terrano 2017 with system Start/Stop (optional for European markets) fuse F21 (15A) responsible for the module ISS (Intelligent Start/Stop). Replacing it without resetting errors through a diagnostic scanner (Launch X431 or similar) may lead to permanent system failure.

💡

If the equipment becomes unstable (for example, the lights flicker or the audio system malfunctions) after replacing the fuse, check quality of contact in the socket. Cleaning the block contacts with an eraser or special liquid often helps. Kontakt 60.

FAQ: Frequently asked questions about fuses Nissan Terrano 2017

Can fuses from other brands (such as Toyota or Hyundai) be used?

Yes, but only if they match standard ATO/ATC (size and denomination). B Terrano 2017 used type fuses Mini Blade (for the cabin unit) and Maxi Blade (for the engine compartment). The main thing is coincidence ampere And physical dimensions. Fuses for Toyota or Hyundai suitable if marked as ATO or ATC.

Which fuse is for the cigarette lighter if my Terrano has two?

In versions with two cigarette lighters (front and rear), they are connected to different fuses:

  • Front cigarette lighter: F12 (20A) in the salon block.
  • Rear cigarette lighter: F24 (15A) (only for versions with option "12V socket for passengers").

If the rear cigarette lighter is not included in your configuration, the slot F24 may be empty or occupied by a "stub".

Why does the cooling fan not turn on after replacing fuse F3 (30A)?

There may be several reasons:

  1. Fan relay is faulty (R3 in the engine compartment). Check it using the replacement method.
  2. The temperature sensor has failed (located on the thermostat). If he refuses ECU does not receive an overheat signal.
  3. Open circuit in power supply. Check the wire from the fuse to the fan connector (black wire with a red stripe).
  4. The fan itself is faulty. Connect it directly to the battery (observing the polarity) - if it does not spin, replacement is required.

B Terrano 2017 with diesel engine also check fuse F27 (10A), which is responsible for the signal from ECU to the fan relay.

Where can I find the fuse diagram for my Terrano if it doesn't match the one in the article?

If your circuit is different, do the following:

  1. Check VIN code car (on the driver's door pillar or under the windshield). From it you can determine the exact configuration.
  2. Download electronic catalog ETM (Electronic Technical Manual) for Nissan Terrano 2017 on the website Nissan TechInfo (registration required).
  3. Contact official dealer asking you to print a diagram for your VIN (the service is paid, but costs ~300 rubles).
  4. Use mobile applications like CarScanner or Torque Pro (paid versions) - they show fuse diagrams for connecting to OBD-II connector.

Please note that patterns may vary even within the same model year due to production line changes. For example, Terrano, manufactured before June 2017, have a different fuse layout for the audio system.

Can I add a fuse myself for new equipment (for example, a DVR)?

Yes, but subject to the rules:

  1. Use free slot in the cabin block (for example, F20 or F26, if they are not busy).
  2. Select a fuse with a rating of 20-30% higherthan the maximum current of the device. For example, for a logger with consumption 1A take the fuse on 2A.
  3. Connect the positive wire via fuse, negative - to the nearest mass point (for example, a seat mounting bolt).
  4. Use heat shrink tube to isolate connections.

⚠️ Important: Do not connect equipment to fuses that control critical systems (ECU, ABS, ESP). This may lead to malfunctions in their operation.
