Nissan Note — a compact and reliable hatchback, but even in it the electrical circuits require attention. Problems with lighting, starter or electronics are often associated with burnt-out fuses or faulty relay. In this article we will look at where the blocks are located in Note first (E11) and second (E12) generations, how to check and replace them without contacting service.

The electrical circuit of the car is protected by dozens of fuses and relays, each of which is responsible for a specific circuit - from the headlights to the engine control unit (ECU). Improper replacement or ignoring signs of malfunction can lead to short circuits or failure of expensive components. We have collected current schemes, unique fuse codes for Russian and European versions, as well as step-by-step instructions for self-diagnosis.

Where are the relay and fuse boxes located? Nissan Note

B Nissan Note fuses and relays are distributed over three main blocks:

  • 🔧 Main unit in the cabin — located to the left of the steering column, under the instrument panel. Access to it opens after removing the protective cover (press the latch on top).
  • 🔋 Block under the hood — located next to the battery (in models with gasoline engines HR15DE And HR16DE). The cover is secured with two latches.
  • 🚗 Additional block — in some trim levels (for example, with climate control) it is installed behind the glove compartment or under the center console.

B Note E12 (2012–2020) block locations are similar, but fuse ratings may differ due to updated wiring. For example, the cigarette lighter fuse in E11 has a face value 15A, and in E12 — 20A.

To avoid confusion, pay attention to marking on the block cover — there is a diagram with the numbers and purpose of each element. If there is no diagram (for example, after replacing a block), use the universal tables below.

Interior block fuse diagram Nissan Note E11/E12

The cabin unit is the most popular for diagnostics. Fuses for lighting, audio systems, power windows and other consumers are concentrated here. Below is the current diagram for Note both generations (differences are indicated in the notes).

Fuse no. Rating (A) Purpose Notes
1 10 Interior lighting, instrument lighting B E12 also responsible for illuminating the glove compartment
7 15 Cigarette lighter, 12V socket Often burns out when using powerful devices
10 10 Audio system, navigation B E12 with Bose - denomination 15A
15 20 Window lifters If the mechanism jams, the fuse may blow
20 10 Engine control unit (ECU) Replace only if you are absolutely sure there is a fault!

⚠️ Attention: fuse №20 (10A, ECU) - critical. Replacing it with a higher denomination or installing a bug may lead to damage to the engine control unit and costly repairs. If it burns out repeatedly, diagnostics of the wiring or sensors is required.

To check the fuse, use a multimeter in continuity mode or visually inspect the filament. If the fuse is intact, but the circuit does not work, the problem may be relay or broken wiring.

💡

Before replacing a fuse, always turn off the ignition and remove the terminal from the battery. This will prevent short circuits if the contacts are accidentally connected.

Relay in Nissan Note: purpose and diagnosis

Relay in Note are responsible for turning on powerful consumers: starter, cooling fan, headlights, etc. Unlike fuses, they do not “burn out”, but can stick, burn contacts or fail due to mechanical wear.

Main relays of the cabin unit:

  • ⚡ Starter relay - located under number R1 (in E11) or R3 (in E12). If there is a malfunction, the engine does not start or clicks are heard without cranking.
  • 💨 Cooling fan relay — R5. If it does not work, the engine overheats (especially in traffic jams).
  • 🔦 Low/high beam relay — R7 And R8. If a breakdown occurs, the headlights do not turn on or only work at full intensity.

To check the relay:

  1. Remove the relay from the socket (carefully pry it off with a screwdriver).
  2. Test the winding with a multimeter - the resistance should be within 50–120 Ohm.
  3. Serve 12V to contacts 85 And 86 — there should be a click (activation).

If the relay is faulty, replace it with a similar one with the same number. As a last resort, you can temporarily install a relay from another circuit (for example, a horn relay instead of a starter relay), but only for testing!

Common problems and their causes

Owners Nissan Note often encounter typical faults related to fuses and relays. Let's look at the most common cases:

1. The cigarette lighter or 12V socket does not work

Reason: fuse blown №7 (15A) or 20A (in E12). This often happens when connecting powerful devices (compressors, inverters). The solution is to replace the fuse and check the consumer for compliance with the rating.

2. Headlights or side lights do not turn on

Culprits:

  • 🔦 Fuse №3 (10A) - dimensions.
  • 🔦 Fuse №4 (10A) - low beam.
  • 🔦 Relay R7/R8 - if the fuses are intact.

Also check the lamps and contacts in the sockets - oxidation can simulate a faulty fuse.

3. The starter clicks but does not turn

Most likely the problem is:

  • ⚡ Starter relay (R1/R3).
  • ⚡ Fuse №18 (10A) - starter control circuit.
  • ⚡ Discharged battery or poor contact at the terminals.

⚠️ Attention: If the problem remains after replacing the starter relay, do not try to “bridge” the contacts with a screwdriver - this may burn the starter winding or ECU. Better check the voltage at the terminal 50 relay when turning the key (should be 12V).

What should I do if the fuse blows again?

If the fuse blows again after replacement, this indicates a short circuit in the circuit. Required:

1. Disconnect all consumers in this circuit.

2. Test the wiring for a short to ground.

3. Check the devices connected to this circuit (for example, a radio or alarm system).

In 80% of cases, a short is to blame in the wiring harness under the panel or in the door (due to chafing of the insulation).

How to replace a fuse or relay: step-by-step instructions

Replacing a fuse or relay in Nissan Note does not require special skills, but it is important to follow the correct sequence to avoid mistakes.

To replace the fuse:

  1. Turn off the ignition and remove the terminal "–"from the battery.
  2. Remove the fuse box cover (press the latch or pull it up).
  3. Locate the faulty fuse using the diagram (on the back of the cover or in the table above).
  4. Remove the fuse with special pliers (available in the unit) or tweezers.
  5. Install a new fuse same denomination.

To replace the relay:

  1. De-energize the circuit (remove "–" with battery).
  2. Carefully remove the relay by rocking it from side to side.
  3. Install a new relay with the same markings.
  4. Check the operation of the circuit after connecting the battery.

⚠️ Attention: Never use fuses with a rating different from that shown in the diagram. For example, setting 20A instead of 10A may lead to fire in the wiring due to overload. If the required fuse is not available, temporarily turn off a non-critical consumer (for example, a radio), but do not install a wire bug!

💡

If after replacing the fuse or relay the problem remains, the reason lies not in them, but in the wiring, consumer or control unit. In this case, in-depth diagnostics are required.

Where to buy fuses and relays for Nissan Note

Fuses and relays for Note They are sold at any auto store, but it is important to choose quality parts. Here's what we recommend:

  • 🛒 Original fuses - article number 28501-4M000 (set for Nissan). Cost: ~300–500 rub.
  • 🛒 Relay — original 25230-4M000 (starter), 25230-AL50A (fan). Price: 600–1200 rub.
  • 🛒 Analogues — Bosch, Hella, Valeo. Fuses Littlefuse or Bussmann are considered the most reliable.

When purchasing a relay, pay attention to:

  • 🔍 Rated current (indicated on the body, for example, 30A/40A).
  • 🔍 Contact type - in Note relays with 4 or 5 contacts are used (standard ISO 280).
  • 🔍 Manufacturer - cheap Chinese relays often stick.

If you are not sure about the choice, take the old relay with you to the store for comparison. As a last resort, you can order parts by VIN-car code via Exist.ru or Autodoc.

Tips for troubleshooting

To ensure that fuses and relays are in Nissan Note served longer, follow simple recommendations:

  1. Check your contacts regularly in fuse boxes - oxidation increases resistance and leads to overheating. Clean contacts with alcohol or a special liquid (Contact Cleaner).
  2. Don't overload the circuits - do not connect devices with more power to the cigarette lighter 120W (for example, car refrigerators). Use fused power strips.
  3. Monitor the condition of the wiring — especially in places of inflection (thresholds, doors). If there are signs of insulation melting, correct the problem immediately.
  4. Check your battery - low voltage (11.5V) may cause relay malfunctions and ECU.

⚠️ Attention: If there is a burning or plastic smell in the cabin, stop immediately and check the fuse boxes. This could be a sign contact melting or short circuit, which is fraught with fire!

It is also useful to conduct an “audit” of the blocks once a year:

  • 🔧 Blow the blocks with compressed air (remove dust).
  • 🔧 Check the fixation of fuses and relays - they should not dangle.
  • 🔧 Inspect the wiring harnesses for chafing.

FAQ: Frequently asked questions about fuses and relays Nissan Note

Is it possible to use a larger fuse if the original one keeps blowing?

No! Increasing the fuse rating leads to the risk of wiring melting or failure of devices in the circuit. If the fuse blows again, look for the cause - a short circuit or a faulty consumer (for example, a jammed window lift motor).

How to distinguish a faulty relay from a working one?

A faulty relay may:

  • Do not click when applying voltage to the winding.
  • Have melted or blackened contacts.
  • Smell like burning.

For an accurate check, use a multimeter (testing the continuity of the winding and contacts).

Where is the fuel pump fuse located? Nissan Note E12?

B Note E12 The fuel pump fuse is located in salon block under number №14 (15A). It is also responsible for the injector chain. If the pump does not work after replacing the fuse, check the relay R2 and voltage at the pump connector (should be 12V when the ignition is turned on).

Why does it blow again after replacing the cigarette lighter fuse?

Most often this happens due to:

  • Short circuit in the 12V socket (check the contacts for a short to ground).
  • A faulty device connected to the cigarette lighter (for example, a faulty charger).
  • Poor contact in the fuse socket (leads to heating and burnout).

Disconnect all devices and test the circuit with a multimeter.

Can I change the entire fuse box myself?

Technically yes, but it is a labor-intensive process. The fuse box is mounted to the body and connected to multiple harnesses. When replacing:

  1. Disconnect the battery.
  2. Take photographs of the location of all fuses and relays.
  3. Disconnect all connectors (they may be secured with latches).
  4. Install the new unit and connect the harnesses in reverse order.

Without experience, it is better to entrust this to specialists - a connection error can damage the car’s electronics.
