<em>Nissan March</em>Trunk Button: Location, Opening and Troubleshooting

Nissan March - a compact hatchback, which is valued for its efficiency and practicality. But even with such a convenient car, owners sometimes encounter non-obvious issues, for example, the trunk open button. Where is it? How does it work? Why might it not work? In this article we will look at everything in detail - from basic instructions to fault diagnosis.

Many drivers March (especially models K13 And K14) are faced with confusion: either the trunk button is hidden in the cabin, or it is not there at all. In fact, it all depends on the configuration and year of manufacture. We have collected up-to-date information including unique nuances for Russian versions of the car, which are often missed in standard manuals.

Where is the trunk button located? Nissan March?

In most trim levels Nissan March The trunk release button is located on the driver's door — next to the power window control unit. However, its appearance and exact location depend on the generation:

• 🔹 K13 (2010–2017): The button is integrated into the door panel, usually under the opening handle or next to the central locking button. Has a trunk pictogram (a stylized hatchback with an open lid).
• 🔹 K14 (2017–present): the button has been moved to the lower part of the panel, closer to the armrest. Can be combined with a fuel tank opening button.
• 🔹 Basic configurations: There may be no button at all - the trunk can be opened only with a key or a lever inside the luggage compartment.

If you don't find the button on the door, check the following places:

• 🔧 Under the steering wheel: on some versions the button is duplicated on the instrument panel to the left of the steering wheel.
• 🔧 In the trunk: A lever or button on the inside of the lid (usually on the right).
• 🔧 On the key: in versions with keyless entry, the button may be on the key fob (indicated by a trunk icon).

How to open the trunk Nissan March without a button?

If the button is missing or not working, use alternative methods:

1. 🔑 Mechanical method: Insert the key into the trunk lock (located on the lid) and turn it counterclockwise. In some versions March The lock is hidden under a decorative trim - you need to carefully pry it off.
2. 🚗 Lever inside the trunk: If the lid is slightly open (for example, through the interior), pull the lever or press the button on the inside. It is usually located on the right, next to the hinges.
3. 🔋 Emergency opening: if the battery is dead or the electric drive is faulty, fold back the rear seat, get to the trunk and pull the emergency release cable (not available on all trim levels).

In models with electric trunk lid (optional for March K14) button can be touch sensitive. If it doesn't respond, check:

• 🔋 Battery charge (at low voltage the electric drive is blocked).
• 🔌 Fuse F27 (10A) in the fuse box under the hood - responsible for the trunk circuit.
• 📶 Presence of interference from other electronic devices (for example, contactless keys).

Why doesn't the trunk button work?

If the button is pressed, but the trunk does not open, the reasons may be either mechanical or electrical. Let's look at the most common ones:

Reason	Symptoms	Solution
Faulty microswitch	The button fails, but there is no click	Replacing a button or its contacts
Broken wiring	The button cannot be pressed or is pressed too easily	Chain continuity testing, wiring repair
Dead battery	The electric drive does not work, but the mechanical opening works	Charging or replacing the battery
Jammed lock	The button clicks, but the lid does not open	Lubricating or replacing the lock
Body Control Module (BCM) Malfunction	Several buttons do not work (for example, trunk + fuel tank)	BCM diagnostics, flashing or replacement

To diagnose the electrical part you will need a multimeter. Check:

1. The voltage on the button when pressed (should be 12V).
2. The resistance of the circuit between the button and the control unit (should be close to 0 ohm).
3. Signal on the actuator (when the button is pressed, a pulse should appear 5V).

How to check the trunk button with a multimeter?

1. Remove the door trim to gain access to the button connector.

2. Connect the multimeter probes to the contacts of the button in dialing mode.

3. Press the button - if the circuit closes (beep), the button is working.

4. If the circuit does not close, replace the button or clean the contacts from oxidation.

⚠️ Attention: If you hear a click when you press the button, but the trunk does not open, do not force the lid. This may damage the hinges or the motor. First check the lock mechanism.

Repair and replacement of trunk button

If the diagnostics showed a faulty button, you can replace it yourself. For this you will need:

• 🔧 Flat screwdriver or plastic puller.
• 🔧 New button (article for March K13: 28521-JM00A, for K14: 28521-JM10A).
• 🔧 Terminal clamps (if the wiring is damaged).

Step by step instructions:

If the button is mechanically sound, but the contacts are oxidized, they can be cleaned:

1. Remove the button from the panel (by carefully prying it off with a screwdriver).
2. Clean the contacts with alcohol or a special electronics cleaner.
3. Apply a thin layer of conductive lubricant (eg Kontakt 60).
4. Reassemble everything in reverse order.

⚠️ Attention: When replacing the button, do not use metal tools to pry up the door trim - this may damage the plastic. It's better to use plastic spatulas or a credit card.

Frequently asked questions about the trunk Nissan March

Owners March often encounter typical trunk-related problems. Here are the answers to the most common ones:

Is it possible to open the trunk if the battery is dead?

Yes, but the method depends on the configuration:

• 🔑 If there is a mechanical lock, use a key.
• 🚗 If there is no lock, fold back the back seat and pull the emergency release cable (if provided).
• 🔋 As a last resort, recharge the battery from another car (“light it”) or use a jump-start charger.

Why does the trunk open by itself?

This is a typical problem for March with electric drive. Reasons:

• 🔧 Microswitch stuck — the button “sticks” when pressed.
• 🔧 Short circuit in wiring - Check the chain for damage.
• 🔧 BCM malfunction - requires diagnostics at a service station.

Workaround: Turn off the fuse F27 (10A) until the fault is eliminated.

How to adjust the trunk lid if it is sagging?

Lid sagging is usually due to worn hinges. To adjust:

1. Open the trunk and look for the adjusting bolts on the hinges (they may be hidden by plugs).
2. Loosen the bolts and adjust the position of the cover so that the gaps are even.
3. Tighten the bolts and check the operation of the lock.

If the hinges are worn out, they will have to be replaced (part number for March K13/K14: 80910-JM00A - left, 80911-JM00A - right).

Modernization: installing a trunk button as standard

If your Nissan March It is not equipped with a trunk button, you can install it yourself. For this you will need:

• 🔧 Button with connector (suitable for year of manufacture).
• 🔧 Wire cross-section 0.5–0.75 mm².
• 🔧 Relay (optional if connecting to BCM).
• 🔧 Soldering iron or terminals for connecting wires.

Connection diagram:

1. Connect the positive wire of the button to 12V (can be taken from the cigarette lighter or fuse box).
2. Connect the negative wire to ground (for example, to a bolt on the body).
3. Route the signal wire to the trunk actuator (usually located next to the lock).
4. If necessary, install a relay if the load current exceeds 5A.

For models with CAN bus (For example, March K14 with the system Nissan Intelligent Key) BCM programming will be required for the button to interact correctly with other systems. It is better to do this at a service station with a diagnostic scanner.

Tips for using the trunk Nissan March

To avoid trunk problems, follow these recommendations:

• 🔧 Lubricate the lock and hinges regularly (once every 6 months).
• 🔧 Do not slam the trunk lid - this leads to deformation of the hinges.
• 🔧 In cold weather, use a lock defroster if the lid does not open.
• 🔧 Check the condition of the seal - if it is cracked, replace it (article: 80310-JM00A).

If you often transport large cargo, consider the maximum load on the trunk lid - up to 50 kg for March K13/K14. Exceeding this value may lead to deformation of the hinges or malfunction of the electric drive.

For convenience, you can install additional accessories:

• 🔧 Electric drive (if it is not included in the package).
• 🔧 Trunk opening sensor — will signal if the lid is not closed.
• 🔧 Organizer - to secure the load and prevent it from moving.
