Yours Nissan Cube refuses to start, and alarm indicators are lit on the dashboard or there is complete silence? This problem is familiar to many owners of compact Japanese hatchbacks, especially those with a mileage of over 150,000 km. Unlike classic sedans like Teana or Skyline, Cube has unique “sores” associated with the body structure, electrical system and ignition system.

In this article we will look at all possible reasons, why the engine does not start - from a banal battery discharge to rare breakdowns of the immobilizer or control unit. You will learn how diagnose a malfunction using sounds and indicators (such as relay clicking or key not responding), and get step-by-step instructions to fix each problem. We will pay special attention to “childhood diseases” Cube with motors HR15DE And KR15DE, which most often become a headache for owners.

1. Battery: the first and most obvious reason

Let's start with the simplest thing - discharged or faulty battery. B Nissan Cube (especially in versions with the system Intelligent Key) even a small voltage drop is lower 11.8 V may prevent the engine from starting. Signs of a problem:

  • 🔋 When you turn the key you can hear relay clicks, but the starter does not turn.
  • 💡 The indicators on the dashboard are dim or flashing.
  • 🚗 The car does not respond to button presses Intelligent Key (if installed).
  • 🔌 Terminal voltage below 12.4 V (measured with a multimeter).

B Cube second generation (2009–2014) common oxidation of battery terminals due to their inconvenient location. Check the contacts: they should be clean, without green deposits. If the battery is discharged, try to “light it” from another car, but take into account the nuance: in Cube with Intelligent Key After lighting the cigarette, the connection with the key may be reset - retraining will be required (instructions below).

⚠️ Attention: Never try to start Nissan Cube with a discharged battery using the towing method! In models with automatic transmission (RE0F10A) this is guaranteed to lead to breakage of the box. Use only the starter or cigarette lighter.
📊 How often do you check the condition of the battery in your Nissan Cube?
  • Every month
  • Once every six months
  • Only when problems arise
  • Never

2. Starter: why doesn’t it turn or turns too slowly?

If the battery is charged but the engine does not start, the problem may lie in starter. B Nissan Cube (especially with a motor HR15DE) the starter often fails after 100,000 km due to:

  • 🔧 Brush wear - a crackling sound is heard, but the shaft does not rotate.
  • 🧲 Winding short circuits — the starter turns jerkily or smokes.
  • 🔗 Bendix breakdowns — a metallic grinding sound is heard when starting up.
  • 🔌 Oxidation of contacts on the solenoid relay (a common problem in humid climates).

For diagnostics:

  1. Check the voltage at the starter control wire (should be 12 V when turning the key).
  2. Ring the starter ground to the body - the resistance should be close to 0 ohm.
  3. If the starter turns, but very slowly, measure the current consumption: the norm for Cube — 150–200 A.

B Nissan Cube 2010–2014 a defect occurs solenoid relay, when it “sticks” after starting. This leads to the fact that the starter continues to rotate after starting the engine - ignoring the problem leads to destruction of the flywheel. The solution is to replace the relay or starter assembly.

Check battery charge (minimum 12.6 V)

3. Immobilizer and Intelligent Key system: start lock

One of the most insidious reasons why Nissan Cube won't start - Malfunctions of the immobilizer or keyless entry system Intelligent Key. Symptoms:

  • 🔑 The dashboard flashes or lights up immobilizer indicator (key icon).
  • 🚫 The engine does not respond to turning the key or pressing the start button.
  • 📛 In some cases it is distributed triple beep when trying to start the car.

B Cube with Intelligent Key common problem - dead battery in the key (even if it is mechanical!). Crashes also occur after:

  • 🔋 Lighting the car (the connection between the key and the control unit is reset).
  • 🔌 Battery disconnection (key retraining required).
  • 🚗 Installation of emergency alarm or autostart.

To reset the immobilizer error in Nissan Cube follow this procedure:

  1. Insert the key into the ignition and turn to position ON (without starting the engine).
  2. Wait 10 minutes — the immobilizer indicator should go out.
  3. Turn off the ignition and try starting again.
⚠️ Attention: If the reset procedure does not help, do not try to “trick” the immobilizer by turning off the fuse! B Cube This will lead to blocking of the engine ECU and the need for flashing.
How do I retrain my Intelligent Key after replacing the battery?

1. Close all doors and insert the key into the ignition.

2. Turn the key to the ON position (without starting the engine) and wait 5 seconds.

3. Turn the key to the OFF position and remove it.

4. Repeat steps 2-3 5 more times (6 cycles total).

5. After the 6th cycle, insert the key and turn to ON - the immobilizer indicator should flash 2 times per second.

6. Within 10 seconds, press any button on the key - the connection will be restored.

4. Fuel system: no gasoline or pump not working

If the starter turns, but the engine does not “catch”, the problem may be fuel system. B Nissan Cube with motor HR15DE often found:

  • 🛢️ Fuel pump failure (a characteristic sign is the absence of a buzzing sound when the ignition is turned on).
  • 🔥 Fine filter clogged (the engine starts and immediately stalls).
  • 🔧 Fuel pressure regulator malfunction (RPM fluctuates at idle).
  • 💧 Water in the gas tank (relevant after refueling at questionable gas stations).

For diagnostics:

  1. Check if you can hear the sound of the fuel pump when you turn on the ignition (in the cabin, under the rear seat).
  2. Measure the pressure in the fuel rail: normal for HR15DE — 3.5–4.0 bar.
  3. Inspect the fuel filter (located under the bottom, next to the gas tank).

B Cube 2012–2014 a defect occurs fuel injectors, when they “stick” due to low-quality gasoline. Symptom - the engine starts only after prolonged cranking with the starter. The solution is to flush the injectors or replace them.

Symptom Probable Cause Solution
The starter turns, but the engine does not catch Fuel pump does not work Check the fuse F15 (15A) and pump relay. Ring the power circuit.
The engine starts and immediately stalls Fuel filter or pump screen is clogged Replace the filter, flush the gas tank.
RPM fluctuates at idle Fuel pressure regulator faulty Replace the regulator (part no. 16600-JM00A).
Engine stutters after starting Clogged or faulty injectors Clean the injectors or replace them (part no. 16600-4M200).

5. Ignition system: spark plugs, coils, wires

B Nissan Cube with motors HR15DE And KR15DE The ignition system is one of the most vulnerable points. Typical problems:

  • ⚡ Spark plug wear (recommended replacement interval - 30,000 km, but many owners drive them up to 100,000 km).
  • 🔥 Breakdown of ignition coils (often after washing the engine or in damp weather).
  • 🔌 Oxidation of contacts in the coil connectors.
  • 📉 Incorrect spark plug gap (must be 1.1 mm).

For diagnostics:

  1. Unscrew the spark plugs and inspect them: the normal color of the electrodes is taupe. Black soot indicates a rich mixture, white soot indicates a poor mixture.
  2. Check the resistance of high-voltage wires: normal - 5–10 kOhm.
  3. Check the ignition coils: primary winding resistance - 0.5–1.0 Ohm, secondary - 8–12 kOhm.

B Cube 2011–2013 a defect occurs cracks in the ignition distributor cap (if installed). This leads to current leakage and misfire. The solution is to replace the cover (part number 22440-4M200).

💡

If after replacing the spark plugs the engine begins to run worse, check their brand! For HR15DE Only candles with a heat rating are suitable 6–7 (For example, NGK IFR6A11 or Denso FK16HR11).

6. Electronic faults: ECU, sensors, wiring

Modern Nissan Cube are equipped with complex electronics, and failures in them can completely paralyze the engine starting. Common problems:

  • 🖥️ ECU firmware failure (for example, after unsuccessful chip tuning).
  • 📡 Crankshaft sensor malfunction (the engine does not start, but the starter turns).
  • 🔌 Short circuit in wiring harness (often after body repair).
  • 🌡️ Coolant temperature sensor failure (The ECU does not calculate the mixture correctly).

To diagnose electronic faults you will need OBD-II scanner. B Cube The following errors are common:

Error code Description Possible reason
P0335 Crankshaft position sensor circuit malfunction Problems with the wiring or the sensor itself (part number 23731-4M200).
P0100 Mass air flow sensor circuit malfunction DMRV is clogged or damaged (part number 22680-4M200).
P0606 ECU checksum error Firmware failure or memory chip damage.
U1000 Lack of communication with the control unit Problems with the CAN bus (check the connectors under the dashboard).

If the scanner shows an error P0606, this could mean that ECU requires flashing. B Cube with the system Intelligent Key After flashing, you need to rebind the keys! This will require diagnostic equipment (for example, Consult-III Plus).

💡

If after replacing the ECU or flashing the engine the engine does not start, check the immobilizer! In 90% of cases, the problem lies in the inconsistency of the key with the new control unit.

7. Mechanical failures: timing belt, marks, compression

If all previous systems are ok, but Nissan Cube stubbornly won't start, worth checking mechanical part of the engine. Typical problems:

  • 🔗 Broken timing belt (the engine does not start, the starter turns easily).
  • 📏 Broken timing marks (for example, after replacing the belt).
  • 💨 No compression in cylinders (wear of piston rings or valves).
  • 🛢️ Jammed oil pump (leads to oil starvation).

In motors HR15DE And KR15DE The timing belt requires replacement every 100,000 km, but many owners forget about this. If the valve belt breaks oppression, which leads to expensive repairs. Check the integrity of the belt through the inspection window in the guard (if there is one) or by removing the upper timing cover.

If you suspect compression problems, take the following measurements:

  1. Unscrew all spark plugs.
  2. Insert the compression gauge into the first cylinder.
  3. Crank the engine with the starter (minimum 5–7 seconds).
  4. Record the readings and repeat for the remaining cylinders.

Normal compression for HR15DE — 12–14 bar. The spread between cylinders should not exceed 1 bar. If the compression is lower 10 bar, the engine requires major overhaul.

8. Other reasons: from alarms to trivial details

Sometimes Nissan Cube does not start for reasons that are difficult to diagnose immediately. Let's consider rare but possible scenarios:

  • 🚨 Alarm failure (blocks the ignition or starter circuits).
  • 🔌 Bulk Wire Oxidation on the body or engine.
  • 🔋 The battery in the key fob is low Intelligent Key (even if the key is mechanical!).
  • 🛑 Activating transport mode (occurs after evacuation).
  • 🌡️ Fuel freezing in the gas tank (relevant for regions with temperatures below -30°C).

If you have an alarm installed (for example, StarLine or Pandora), try resetting it to factory settings. B Cube The alarm system often conflicts with the standard immobilizer, especially if it is not installed properly.

One more nuance - bulk wires. B Nissan Cube they often oxidize in places where they are attached to the body (under the battery and on the front panel). Clean contacts and treat them LIQUI MOLY Kupfer-Spray.

💡

If the engine does not start after washing, check the connectors of the sensors and ignition coils! B Cube they are often located in niches where water accumulates.

FAQ: Frequently asked questions about the launch of Nissan Cube

My Cube won't start, the starter won't turn, but the dash lights up. What's the matter?

Most likely the problem is starter contacts or its control relay. Check:

  1. The voltage on the starter control wire when turning the key (should be 12 V).
  2. Fuse integrity F30 (10A) in the block under the hood.
  3. The condition of the ground wire on the starter (often oxidizes).

If the starter clicks but does not turn, the brushes are most likely worn out or the winding is shorted.

After replacing the battery, the Cube does not start, the key on the panel flashes. What to do?

This is a standard situation for Nissan Cube with Intelligent Key — the binding of the key to the immobilizer has been reset. Perform the retraining procedure:

  1. Insert the key into the ignition.
  2. Rotate to position ON (without starting the engine) and wait 10 minutes.
  3. Turn off the ignition, remove the key and try starting again.

If this does not help, you will need diagnostics with a scanner (for example, Launch X431).

The engine turns over, but does not catch. There is gasoline in the tank, new spark plugs. What to check?

Probable reasons:

  • 🛢️ Fuel pump does not work (check the voltage at its connector).
  • ⚡ No spark (check ignition coils).
  • 📡 Crankshaft sensor faulty (error P0335).
  • 🔌 Engine weight problems (contacts are oxidized).

Start by checking the fuel rail pressure (should be 3.5–4.0 bar).

Cube starts only after several attempts. What could be the problem?

Typical reasons:

  • 🔥 Air leak through cracks in the manifold or gaskets.
  • 🛢️ Clogged fuel injectors (washing required).
  • 📉 Throttle valve wear (needs cleaning or replacement).
  • 🔋 Weak battery (voltage drops during startup).

Check vacuum hoses for cracks and error codes scanner.

Is it possible to push start the Cube if the starter does not work?

Absolutely not! B Nissan Cube with automatic transmission (RE0F10A) starting from a pusher will lead to gearbox failure. For manual transmission (RS5F92A) is theoretically possible, but:

  • Risk of clutch damage.
  • Possibility of immobilizer failure.
  • Load on the timing belt (may slip).

It is better to call a tow truck or use a jump starter.
