<em>Nissan Note</em>starter relay: location, diagnosis and DIY replacement

When Nissan Note refuses to start, and only clicks or complete silence are heard from under the hood; the culprit is often the starter relay. This small part plays a key role in the engine starting system, and its malfunction can immobilize the car at the most inopportune moment. Unlike the starter itself, which requires serious repairs, the relay can be replaced yourself in 15–20 minutes - if you know where it is and how to test it correctly.

In this article we will figure out how to distinguish a relay malfunction from problems with the starter or battery, and where to look for the part on different generations Nissan Note (including restyled versions), and what tools are needed for diagnostics. You will also learn why even a new relay can quickly fail, and how to avoid repeated breakdowns. For clarity, we provide connection diagrams, a spare parts compatibility table and step-by-step instructions with photos.

Signs of a faulty starter relay on Nissan Note

The starter relay rarely breaks suddenly - usually its “departure” is accompanied by a number of symptoms that can be noticed in advance. The main difficulty is that these same signs may indicate problems with the battery, starter, or even the alarm. Here's how to recognize a relay malfunction:

• 🔊 Starter clicks without cranking. When you turn the key, you hear a single or multiple click, but the engine does not start. This is a classic sign that the relay is tripping but the contacts are not closing properly.
• 🔋 The starter works "every time". Sometimes the car starts the first time, and sometimes it takes several tries. This “floating” symptom often indicates burnt contacts inside the relay.
• 🔥 Burning smell from under the hood. If you feel burnt plastic or metal when you try to start, this may mean the relay contacts are burning or sticking.
• ⚡ Voltage drop in the on-board network. When the starter is turned on, the dashboard or headlights go out - a sign that the relay cannot cope with the load.

It is important not to confuse these symptoms with a dead battery. If when you turn the key there is not even a click, and the indicators on the dashboard dim, the problem is most likely in the battery or terminals. If there are clicks, but the starter does not turn, the culprit with an 80% probability is the relay or the starter itself.

⚠️ Attention: On Nissan Note with the system Intelligent Key (keyless entry) similar symptoms can be caused by a faulty immobilizer. Before replacing the relay, check whether the immo indicator on the device flashes when you try to start.

Where is the starter relay located on Nissan Note?

The location of the relay depends on the year of manufacture and vehicle equipment. On most versions Nissan Note (including E11 And E12) the part is installed in one of two places:

1. Fuse box in the passenger compartment (under the dashboard on the driver's side). The starter relay is usually labeled as Starter Relay or IGN Relay and has a standard size (like ISO 280).
2. Fuse box under the hood (near the battery). Here the relay can be combined with the main ignition relay or installed separately.

To accurately determine the location, use the diagram for your modification:

Model/Year	Relay location	Number in block	Relay type
Nissan Note E11 (2004–2009)	Interior, fuse box (driver's left foot)	R17 or R27	4-pin, 12V
Nissan Note E12 (2012–2017)	Under the hood, main fuse box	R5 or R6	5-pin, with diode
Nissan Note e-Power (2017–present)	Interior, block behind the glove box	R30	Electronic, with short circuit protection

On some versions the starter relay can be combined with a relay ignition or fuel pump. To avoid mistakes, check the fuse box cover - there is usually a diagram with symbols there. If there are no inscriptions, use a multimeter to check (more on this below).

How to test the starter relay with a multimeter?

Before replacing the relay, be sure to make sure that this is the problem. To do this, you will need a multimeter (or even a simple 12V light bulb) and a screwdriver. Follow the step by step instructions:

Remove the relay from the fuse box|Check the control circuit (pins 85 and 86)|Apply 12V to the relay coil|Check the circuit of the power pins (30 and 87)|Make sure there is no open or short circuit-->

Step 1: Removing the Relay

Carefully pull the relay out of the socket (you can pry it off with a screwdriver). Pay attention to the markings of the contacts - they are usually labeled on the relay body or on the block diagram. If there are no markings, remember the location of the contacts (better take a photo).

Step 2. Check the winding

Connect the multimeter in resistance test mode (200 Ohms) to the contacts 85 And 86 (control pins). The resistance of a working winding should be within 50–120 Ohm. If the device shows OL (break) or 0 (short circuit), relay is faulty.

Step 3. Trigger check

Apply voltage 12V from battery to contacts 85 And 86 (polarity is not important). At the same time, a distinct click should be heard - this means that the winding has worked and closed the power contacts. If there is no click, the relay must be replaced.

Step 4. Checking power contacts

In continuity mode, check the short circuit between 30 And 87 when 12V is supplied to the winding. If the circuit does not close, the contacts are burnt or oxidized. Also make sure that in the original state (no voltage) between 30 And 87 no short circuit.

⚠️ Attention: On Nissan Note E12 with the system Stop/Start The starter relay may have an additional contact for communication with the ECU. Check such relays strictly according to the diagram, since their internal design differs from the standard ones.

Step-by-step replacement of the starter relay with Nissan Note

If the diagnostics confirm that the relay is faulty, you can replace it yourself. For this you will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔌 New relay (analogue or original).
• 🧴 WD-40 or contact lubricant (optional).

Step 1: Power off

Remove the negative terminal from the battery to avoid short circuit. On Nissan Note with the system Intelligent Key after disconnecting the battery, the keys may need to be retrained (the procedure is described in the manual).

Step 2: Access the Fuse Box

If the relay is located in the passenger compartment, remove the fuse box cover (usually it is secured with latches). Under the hood, the unit may be covered with a plastic panel - it needs to be carefully pryed off with a screwdriver.

Step 3: Removing the old relay

Press the relay lock (if equipped) and pull it out of the socket. Pay attention to the condition of the contacts in the block - if they are oxidized, clean them with fine sandpaper or a special spray.

Step 4: Installing a New Relay

Insert the new relay into the socket until it clicks. Make sure it is tightly seated - poor contact can cause re-burning. If you are using a non-original part, check the compatibility table (see below).

Step 5. Checking the work

Connect the battery terminal and try to start the car. If the starter turns clearly, without delays, the replacement was successful. If the problem persists, check the circuit from the relay to the starter or diagnose the starter itself.

What to do if the new relay burns out quickly?

If the installed relay fails within a short time, the cause may be:

1. **Short circuit in the starter circuit** - check the wires from the relay to the starter for damage to the insulation.

2. **Poor contact in the fuse box** - oxidized or burnt sockets increase resistance, which leads to overheating of the relay.

3. **Starter malfunction** - if the starter draws too much current (for example, due to worn brushes), the relay is overloaded.

4. **Alarm or Immobilizer Problems** - Some security systems block the starter circuit, which can cause the relay to overload.

In such cases, comprehensive diagnostics of electrical equipment is required.

Starter relay compatibility: original vs analogs

For Nissan Note the original starter relay has a part number 25230-JM00A (for E11) or 25230-4M21A (for E12). However, it can be replaced with analogues from other manufacturers, which are cheaper but not inferior in quality. Below is the compatibility table:

Original article	Manufacturer of analogue	Analog article	Notes
25230-JM00A	Bosch	0 332 209 150	Suitable for E11, 4-pin
25230-4M21A	Hella	4RA 003 537-331	For E12, with protection diode
25230-4M21B	Febi Bilstein	25230	Universal, for models with Stop/Start
25230-JM01A	Meat & Doria	88.3771	Budget option, resource ~50 thousand km

When choosing an analogue, pay attention to:

• 🔌 Number of contacts (4 or 5). Relay with diode (for E12) are not interchangeable with standard ones.
• 📏 Case dimensions. Even if the contacts match, the relay may not fit into the socket due to its dimensions.
• ⚡ Rated current. For Nissan Note with diesel engine (1.5 dCi) a relay with a current of at least 30A.

⚠️ Attention: On Nissan Note e-Power (hybrid) an electronic relay with a control chip is installed. You cannot replace it with a conventional mechanical analogue - this will lead to errors in the ECU and system failure Start/Stop.

Common mistakes when replacing a starter relay

Even such a simple operation as replacing a relay can result in new problems if mistakes are made. Here's what's most often done wrong:

• 🔧 Ignoring oxidized contacts. If the sockets in the fuse box are coated, the new relay will quickly fail. Be sure to clean the contacts with alcohol or a special spray.
• 🔄 Confusion with contacts. If the relay is installed upside down or with the terminals reversed, the starter circuit will not work. Always refer to the diagram on the unit cover.
• 🔋 Forget about resetting errors. On Nissan Note with CAN bus after replacement the relay may light up Check Engine. In this case, you need to reset the error using a scanner or by disconnecting the battery for 10 minutes.
• 🛠️ Use of incompatible analogues. Relays from other brands (for example, Toyota or VW) may not be suitable in terms of current or response time.

Critical error: on some versions Nissan Note The starter relay is connected to the fuel pump relay through a common circuit. If after replacement the car does not start and you cannot hear the pump running, check the fuse F10 (15A) - it often burns out when there is a short circuit in the relay.

Prevention: how to extend the life of the starter relay?

The starter relay is a consumable, but its life depends on operating conditions. To avoid frequent replacement, follow these tips:

• 🔋 Monitor the battery charge. A discharged battery causes the starter to work with increased load, which accelerates the wear of the relay.
• 🔧 Clean the fuse block contacts. Once a year, remove the block and treat the contacts with a protective spray (for example, CRC 2-26).
• 🚗 Avoid lengthy startup attempts. If the car does not start after 3-4 attempts, look for the reason, and do not “force” the starter.
• 🔌 Check the starter circuit. Periodically measure the voltage at the relay contacts during startup - it should not fall below 10.5V.

On Nissan Note With a mileage of more than 150 thousand km, it is recommended to carry out preventive replacement of the starter relay and fuel pump every 2-3 years, even if there are no signs of malfunction. This is cheaper than repairing the starter or diagnosing the electronics after a sudden failure.

Frequently asked questions about the starter relay Nissan Note

Is it possible to start the car if the starter relay is burned out?

Yes, there are two ways:

1. Close contacts manually. Remove the relay and connect the contacts with a screwdriver 30 And 87 (power circuit). This will apply voltage directly to the starter. Danger! Do not touch other parts with the screwdriver - a short circuit may occur.
2. Use backup relay. In the fuse box, look for relays with the same markings (for example, fan or defroster relay) and temporarily swap them.

Both methods are only suitable for emergency starting. Driving for a long time without a relay will damage the starter.

Why does the new relay click, but the starter does not turn?

There are several reasons:

• 🔌 Open circuit between relay and starter - Check the wiring and terminals on the starter.
• 🔋 Low battery - even if the relay is triggered, the voltage may not be enough to crank the starter.
• 🔧 Malfunction of the starter itself - wear of brushes or bearings.
• 📶 Poor ground contact — check the ground wire from the battery to the body and engine.

Start by checking the voltage at the starter when turning the key - it should be at least 11V.

Which starter relay is suitable for Nissan Note 1.6 2015?

For Nissan Note E12 (2012–2017) with engine HR16DE the original relay has an article number 25230-4M21A. Suitable analogues:

• Bosch 0 332 209 155 (5-pin, with diode).
• Hella 4RA 003 537-351.
• Febi 25230 (universal).

The cost of the original is ~1,200 rubles, analogues are from 300 to 800 rubles.

Can the starter relay be repaired?

Theoretically yes, but in practice it is impractical. A relay is a sealed unit with contacts and a winding. When disassembling its body (if it is not riveted), you can:

• Clean burnt contacts with sandpaper.
• Replace the spring or armature (if you find spare parts).

However, after repair, the reliability of the relay drops sharply, and the cost of a new one does not justify the risks. The exception is rare relays for hybrid versions, which are difficult to find on sale.

Why does the starter relay get hot?

Overheating of the relay is a sign of increased load. Main reasons:

• 🔥 Poor contact in the circuit - oxidized terminals or wires increase resistance.
• 🔧 Starter wear - if it consumes more current due to worn parts, the relay is overloaded.
• 📉 Low battery voltage - when the battery is discharged, the current in the starter circuit increases.

If the relay is hot (cannot be held by hand), check the voltage drop on the wires from the battery to the starter - it should not exceed 0.5V.
