Nissan Juke - a compact crossover with a bright design, but even such a reliable car periodically blows fuses. If your headlights fail, the cigarette lighter does not work, or the heater fan refuses to start, the first thing you should check is fuse box. In this article you will find current schemes for Juke first (J10, 2010–2014) and second (J11, 2014–2019) generations, a detailed explanation of each element, as well as step-by-step instructions for diagnosis and replacement.

We will not just list the purpose of fuses - we will explain how to check them correctly (including without a tester), what symptoms indicate specific malfunctions, and why even minor electrical problems cannot be ignored. At the end of the article you will find an FAQ with answers to the most frequently asked questions from owners. Juke, including problems with fuse F37 (15A), responsible for the start-stop system - its failure often leads to the inability to start the engine.

Where are the fuse boxes located in Nissan Juke

B Nissan Juke There are two main fuse blocks:

  • 🔧 Main unit in the cabin — located to the left of the steering column, behind the plastic cover. Access to it opens by turning three clamps.
  • 🚗 Additional block under the hood — located next to the battery (on models with gasoline engines HR16DE And MR16DDT). On diesel versions (K9K) can be moved closer to the windshield.

On vehicles 2015 and newer (J11) in the cabin added third mini-block behind the glove compartment - it is responsible for the multimedia system and rear view camera. This is often overlooked, although this is where the fuse is located F101 (10A), responsible for the operation of the screen.

To avoid confusion, remember a simple rule: if the problem is related to lighting, climate or appliances — look for the fuse in the cabin. If the fault concerns engine, automatic transmission or ignition system — check the block under the hood.

Cabin block fuse diagram (J10 And J11)

Cabin fuse box in Nissan Juke unified for both generations, but there are nuances: on restyled models (J11) added fuses for the system NissanConnect and driver assistants. Below is the current diagram with decoding for most configurations.

Designation Rating (A) Purpose Symptoms of a problem
F1 10 Body Control Module (BCM), Immobilizer The central locking does not work, the alarm does not work
F10 15 Cigarette lighter, 12V socket Phone charging does not work, DVR does not turn on
F20 7.5 Front fog lights PTF does not light up, error B2555 on the dashboard
F37 15 Start-stop system, oil pressure sensor The engine stalls while driving and lights up Check Engine
F45 20 Heater fan The stove does not blow, only cold air

Please note: on models with automatic transmission (CVT) a fuse has been added to the interior block F50 (10A), responsible for automatic transmission solenoids. Its failure can be manifested by jerks when changing gears or the transmission going into emergency mode.

How to check a fuse without a tester?

If you don’t have a multimeter at hand, you can use the “replacement method”: take a known-good fuse of the same rating from another socket (for example, from the rear fog lights) and install it in the place of the suspect. If the problem disappears, the fuse has blown. Important: do not use fuses with a different rating, even “during testing”!

Engine compartment fuse diagram

Block under the hood in Nissan Juke is responsible for high-voltage circuits: ignition, fuel pump, injection system and generator. Here fuses of increased rating are used (up to 100A), and their replacement requires special care.

Key elements of the engine compartment:

  • ⚡ F101 (30A) — Engine computer (ECM). If the engine burns out, the engine will not start, the dashboard will light up Check Engine.
  • ⛽ F103 (15A) — Fuel pump. Symptoms: the engine does not start, but the starter turns.
  • 🔥 F105 (60A) — Main ignition relay. If it fails, there is no power to the instrument panel at all.
  • 🔋 F108 (100A) — Generator. Burns out when there is a short circuit in the charging circuit, leading to battery discharge.

On turbocharged versions (MR16DDT) an additional fuse appears in the block F110 (20A) to control the turbine. Its malfunction is manifested by loss of power and error P0299 (low boost pressure).

💡

If after replacing the fuse under the hood it blows again, do not rush to install a new one! This is a sign of a short circuit in the circuit. Be sure to check the wires for melted or damaged insulation, especially around the generator and starter.

How to correctly replace a fuse in Nissan Juke

Replacing a fuse seems like a simple operation, but Juke There are several nuances that can lead to serious problems. For example, incorrect fuse installation F103 (15A) for the fuel pump may cause fire due to sparking contacts. Follow the step by step instructions:

Turn off the ignition and remove the key from the lock

Remove the negative terminal from the battery (required!)

Prepare tweezers or a special puller

ONLY use a fuse of the same rating-->

To replace you will need:

  1. Tweezers (usually included with the car in the glove compartment).
  2. New fuse same denomination and color (see table below).
  3. Flashlight - The lighting in the fuse box is often insufficient.
  4. Multimeter (optional, to check the circuit after replacement).
Fuse color Rating (A) Application example in Juke
Red 10 BCM, immobilizer (F1)
Blue 15 Cigarette lighter (F10), start-stop (F37)
Yellow 20 Stove fan (F45), automatic transmission solenoids
Green 30 Engine ECU (F101)

After replacing the fuse be sure to check the operation of the circuit. For example, if you changed F10 (15A) for the cigarette lighter, connect the charger and make sure it works. If the fuse blows again, there is a short circuit in the circuit, and wiring diagnostics are required.

💡

Never use "bugs" (homemade jumpers) instead of fuses! In Nissan Juke, this can lead to a wiring fire, especially in the fuel pump circuits (F103) and generator (F108).

Frequent problems with fuses in Nissan Juke and their solutions

Owners Nissan Juke often encounter typical faults related to fuses. Here are the most common cases and how to fix them:

  • 🔌 The cigarette lighter fuse has blown (F10):

    Reason: use of powerful devices (for example, car vacuum cleaners) or a short circuit in the outlet. Solution: check the socket contacts for oxidation, use a protected power strip.

  • 💡 Headlights don't work (F15, F16):

    Cause: often associated with oxidation of contacts in the block or relay malfunction K9 (low beam relay). Solution: clean the contacts with alcohol, check the relay.

  • 🚗 Engine won't start, fuse F103 (15A) burned out:

    Cause: short circuit in the fuel pump circuit or malfunction of the pump itself. Solution: Check the wiring from the pump to the fuse box, replace the pump if necessary.

  • ❄️ The stove doesn't work (F45):

    Cause: Often associated with worn fan brushes or jammed motor. Solution: Before replacing the fuse, check that the fan rotates freely by hand.

Particular attention should be paid to the fuse F37 (15A)responsible for the start-stop system. On Juke 2015–2019 it often fails due to faulty oil pressure sensor. If the fuse blows repeatedly, check the sensor (located on the cylinder block) and its wiring.

💡

If your Juke frequently blows fuses on the same circuit (such as the cigarette lighter), install an additional decoupling relay. This will reduce the load on the standard wiring and prevent short circuits.

Troubleshooting: when the fuse is not to blame

It's not always an electrical problem Nissan Juke connected to fuses. Sometimes the symptoms are similar, but the cause lies deeper. Here's how to differentiate a bad fuse from other problems:

  • 🔍 If only one device does not work (for example, a radio), but the fuse is intact - check relay or the device itself.
  • ⚡ If the fuse blows immediately after replacement - there is a short circuit in the circuit. It is necessary to check the wiring with a multimeter in the "continuity" mode.
  • 📶 If the problem occurs periodically (for example, the cigarette lighter may or may not work) - poor contact in the fuse box or oxidation of the terminals is to blame.

For example, if it doesn't work for you heated seats, but the fuse F25 (20A) okay, the reason could be:

  • Faulty relay K12;
  • Broken wire in the seat cushion;
  • Malfunction of the climate control unit.

To diagnose such problems, you will need a wiring diagram. Nissan Juke (it can be found in the repair manual or on specialized forums). In difficult cases, we recommend contacting an auto electrician with equipment to test the circuits.

💡

If the problem persists after replacing the fuse, check the corresponding relay in the block. In a Nissan Juke, relays and fuses often work in pairs, and the failure of one may masquerade as a failure of the other.

FAQ: Frequently asked questions about fuses Nissan Juke

Is it possible to use a fuse with a higher rating if the standard one constantly blows?

No, this is extremely dangerous! The fuse is designed for a certain load, and if it blows, there is a problem in the circuit (short circuit or increased current consumption). Installing a fuse with a larger rating may result in wiring fire, especially in the fuel pump or generator circuits. Instead, find and fix the cause of the burnout.

Where can I find a fuse diagram for my Juke trim?

The fuse diagram may vary depending on the year of manufacture and configuration. You will find the exact diagram for your car:

  • B instruction manual (section "Electrical equipment");
  • On back of the fuse box cover (sometimes the current diagram is indicated there);
  • On specialized forums (for example, Nissan Juke Club or Drive2), where owners post photos of their blocks.

To accurately define the scheme, indicate VIN of your car — it can be used to determine the configuration and features of electrical equipment.

What to do if after replacing the fuse F103 (15A) engine won't start?

fuse F103 is responsible for the fuel pump. If after replacing it the engine does not start, check:

  1. Presence of voltage at the fuel pump connector (should be 12V when the ignition is turned on);
  2. Operation of the fuel pump relay (K1 in the engine compartment);
  3. The integrity of the wiring from the fuse box to the pump (often frays under the rear seat).

If the pump does not hum when the ignition is turned on, the problem is either in the pump itself or in the power circuit. On Juke with diesel engine K9K additionally check the fuse F112 (10A), responsible for glow plugs.

How to remove the fuse box in the passenger compartment to clean the contacts?

To remove the interior fuse box in Nissan Juke follow these steps:

  1. Disconnect the negative terminal of the battery.
  2. Remove the plastic block cover by turning the three latches counterclockwise.
  3. Unscrew two bolts Torx T20, securing the block to the body (they are located in the lower part).
  4. Carefully disconnect all connectors from the back of the unit (remember their location!).
  5. Remove the unit and clean the contacts with alcohol or a special electronics fluid.

When reassembling, make sure that all connectors are tightly secured - loose contact can cause blown fuses.

Which fuses are responsible for the multimedia system and rear view camera?

B Nissan Juke second generation (J11) are responsible for multimedia:

  • F101 (10A) — main power supply to the head unit;
  • F104 (15A) — sound amplifier (if installed);
  • F107 (10A) — rear view camera and parking sensors.

On models with the system NissanConnect additionally check the fuse F110 (15A) in the cabin unit - it is responsible for the communication module. If the screen does not turn on after replacing these fuses, reset your media settings by holding down the Power 10 seconds.
