Where is the starter relay located on Nissan Almera G15: photo, diagram and replacement instructions

Owners Nissan Almera G15 (2013-2018) often encounter engine starting problems that are associated with a faulty starter relay. This small part can cause big troubles: from intermittent failures to complete failure of the starting system. Unlike classic models, where the relay was installed in the engine compartment, in Almera G15 the manufacturer placed it in an unobvious place.

In this article you will find exact coordinates of the location of the starter relay with reference to the VIN code and year of manufacture, photos and diagrams of the mounting block, as well as step-by-step instructions for diagnosis and replacement. We'll figure out why on some versions of Almera G15 the starter relay is missing from the standard fuse box and where to look for it in such cases. The material was prepared based on data from service manuals Nissan and the experience of auto electricians from forums drive2.ru And almera-club.ru.

Where is the starter relay located on Nissan Almera G15: official diagram

In most cases the starter relay is on Almera G15 located in fuse and relay mounting block, which is located inside the car - under the instrument panel, to the left of the steering column. However, there are nuances here:

• 🔧 For vehicles 2013–2015 (before restyling) the starter relay is designated as K11 and is located in the main fuse box.
• 🔄 For restyled models 2016–2018. the relay can be moved to additional block under the hood (next to the battery).
• ⚠️ On versions with automatic transmission sometimes installed double relay (starter and start interlock), which complicates the search.

To determine your exact location, check electrical diagram your modification. Below is a table with the pinout of the fuse box for Almera G15:

Designation	Purpose	Denomination (A)	Location
K11	Starter relay	—	Main unit (lounge)
F30	Starter circuit fuse	10	Main unit (lounge)
K25	Starter interlock relay (automatic transmission)	—	Additional block (under the hood)
F10	Ignition fuse	7.5	Main unit (lounge)

If your unit does not have a relay marked K11, this does not mean its absence. On some trim levels Almera G15 the starter relay is integrated into engine control unit (ECU) or replaced by solid state relay (without mechanical contacts). In such cases, diagnostics using a scanner is required ELM327 or multimeter.

What the starter relay looks like: photo and markings

Starter relay on Nissan Almera G15 - this is standard 4 pin relay type 90.3747-10 (analogue Hella 4RA 003 547-3 or Bosch 0 332 019 150). It can be identified by the following characteristics:

• 📏 Dimensions: 20×20×30 mm (standard housing for automotive relays).
• 🔢 Marking: on the top cover there is an inscription K11 or STARTER RELAY.
• 🔌 Contacts: numbering 85, 86, 87, 30 (standard for relays with normally open contacts).

Below are photos of the starter relay for Almera G15 (original on the left, analogue on the right):

Original relay: black body with white markings Nissan 25230-4M000 or 25230-4M010. There are markings on the contacts +B (food) and ST (control from the ignition switch).

Analogue: may have a blue or gray body (eg Hella or Valeo), but must comply with the parameters 12V, 30A.

⚠️ Attention: Do not confuse the starter relay with solenoid relay (solenoid), which is located directly on the starter housing under the hood. They perform different functions and are not interchangeable!

Signs of a faulty starter relay on Almera G15

Before looking for a relay, make sure that this is the problem. Typical symptoms of a malfunction:

• 🔊 Starter clicks without cranking: When turning the key, a single click is heard, but the engine does not start.
• 🔄 Intermittent startup failures: The starter fires every once in a while, especially after the engine warms up.
• 🔥 Contacts burning: burning smell from under the instrument panel or visual traces of melting on the relay.
• 🚗 Starting only from the "pusher": The engine starts when towing, but does not respond to the key.

For an accurate diagnosis, check with a multimeter:

1. Remove the relay K11 from the block.
2. Connect the multimeter probes to the contacts 85 And 86 (control circuit). There must be resistance 50–120 Ohm.
3. Serve 12V to contacts 85 And 86 - a click should be heard (contacts closing 30 And 87).

If the relay does not click or the resistance is different, it must be replaced. Also check fuse F30 (10A) - it often burns out due to short circuits in the starter circuit.

Step-by-step instructions for replacing the starter relay

Replacing the relay with Nissan Almera G15 takes no more than 10 minutes. You will need:

• 🔧 Flat screwdriver (for removing the block cover).
• 🔍 Flashlight (lighting the mounting block).
• 🔋 New relay (original or analogue with parameters 12V, 30A).

Sequence of actions:

1. Disable negative battery terminal (required!).
   Why do you need to disconnect the battery?

   When working with electrical Almera G15 There is a risk of a short circuit that could damage the engine control unit (ECU). Even when the ignition is turned off, some circuits remain energized, especially if an alarm system with auto start is installed.

2. Remove the cover of the mounting block by prying it off with a screwdriver on the left side (the latches are located there).
3. Find the relay K11 (see diagram above) and carefully remove it by pulling it up.
4. Install the new relay, making sure the contacts line up with the connector.
5. Return the unit cover to its place and connect the battery.

⚠️ Attention: If after replacing the relay the starter still does not work, check solenoid relay on the starter itself (located under the hood, on the starter housing). Its malfunction manifests itself with similar symptoms, but requires a different approach to repair.

Frequent mistakes during diagnostics and repairs

Many owners Almera G15 make typical mistakes that lead to unnecessary expenses or aggravation of the problem. That's what can't do:

• 🔨 Knock on the starter: This may damage the bendix gear or solenoid relay. On Almera G15 the starter is sensitive to mechanical stress.
• 🔥 Ignore fuse F30: If it is burnt out, replacing the relay without eliminating the cause of the short circuit will lead to repeated failure.
• 🔧 Install relays from other models: even if it is externally identical, the operating parameters may differ (for example, a relay from Nissan Juke not suitable for Almera G15).

Another common mistake is incorrect immobilizer diagnosis. On Almera G15 with the system NATSS (Nissan Anti-Theft System) starting block can simulate a starter malfunction. If after replacing the relay the engine does not start and the immobilizer indicator flashes on the dashboard (🔑), key retraining or ECU reset is required.

Alternative ways to start the engine with a faulty relay

If the starter relay fails on the road, and there is no replacement at hand, you can use temporary solutions:

1. Close the relay contacts manually:
   • Remove the relay K11 from the block.
   • Take a screwdriver or a piece of wire and close the contacts 30 And 87 (they are responsible for supplying current to the starter).
   • Turn the key to position START - the starter should work.

   ⚠️ Attention: This method only works if the solenoid relay and the starter itself. Do not use it often - you may burn the fuse box contacts!

2. Push launch (only for manual transmission):
   • Turn on the ignition.
   • Accelerate the car to 10–15 km/h (using a tow or downhill).
   • Engage 2nd gear and release the clutch - the engine should start.

These methods are only suitable for emergency situations. Long-term operation with a faulty relay leads to starter overheating and failure of its windings.

FAQ: Frequently asked questions about the starter relay on the Nissan Almera G15

Can I use a relay from another Nissan model?

Theoretically yes, but only if it has identical parameters: 12V, 30A, 4 contacts with markings 85, 86, 87, 30. For example, a relay from Nissan Note (2013–2016) or Nissan Micra (K13). However, the original relay 25230-4M000 more reliable, since it is designed for current loads Almera G15.

Why does the starter spin after replacing the relay, but the engine does not start?

This may be due to:

1. Malfunction crankshaft position sensor (DPKV).
2. Immobilizer lock (key retraining required).
3. Lack of signal from idle speed sensor (DHH).

Check with a scanner ELM327 presence of errors in the ECU (for example, P0335 - DPKV malfunction).

Where to buy an original starter relay for Almera G15?

Original relay Nissan 25230-4M000 you can order:

• 🛒 Official dealers Nissan (price ~1,200–1,500 rub.).
• 🌍 Online stores: exist.ru, emex.ru, avtoall.ru (price ~800–1,000 rub.).
• 🔧 Auto electrical stores (for example, Auto electrics or Chip and Dip).

Analogues (Hella, Bosch, Valeo) are cheaper (300–600 rubles), but last less (resource ~50,000 cycles versus ~100,000 for the original).

How to test the starter relay control circuit?

To check the circuit you will need a multimeter in continuity mode:

1. Disconnect the connector from the relay K11.
2. Connect one probe to the contact 86 (mass), the second - to 85 (control from the lock).
3. Turn the key to position START - tension should appear 12V.
4. If there is no voltage, check fuse F10 (7.5A) and a circuit from the ignition switch to the relay.

Can a faulty starter relay damage the battery?

Yes, but indirectly. If the relay is stuck closed, the starter will rotate continuously, resulting in:

• 🔋 Deep battery discharge (for 10–15 minutes of continuous operation of the starter).
• 🔥 Overheating of the starter windings and its failure.
• ⚡ Damage to fuse box contacts due to increased current.

At the first sign of “sticking” (the starter does not turn off after starting the engine), immediately disconnect the battery!
