Removing the passenger airbag (SRS) on Nissan Almera Classic - a task that owners face when repairing a dashboard, replacing the trim or diagnosing a passive safety system. Unlike more modern models, where the pillow is integrated into a plastic panel, Almera Classic (especially restyled versions B10 And N16) the fastening is made according to a simplified scheme. However, even here, errors can cause the squib to fire or damage the wiring.
In this article you will find detailed instructions with photos, a list of necessary tools and critical nuances of working with the SRS system, which are not mentioned in standard manuals. We will look at how to avoid false activation of the airbag, which contacts should not be closed, and what to do if the lamp lights up after removal Airbag on the dashboard. The material is relevant for petrol and diesel versions Almera Classic 2000–2012 release.
Preparation: Tools and Safety Precautions
Before starting work, be sure to disconnect the battery — this minimizes the risk of accidental deployment of the airbag. B Nissan Almera Classic power is supplied to the squib even when the ignition is turned off, therefore:
- 🔧 Tools: socket wrench
10 mm, screwdriver with Phillips bitPH2, plastic spatulas for removing clips, multimeter (for checking the circuit). - 🔋 Battery: remove the terminal
"minus"and wait at least 10 minutes — this time is necessary to discharge the capacitors in the unit SRS. - 🧤 Protection: Wear gloves and safety glasses. When triggered, the powder from the squib can cause burns to mucous membranes.
- 📸 Documentation: Take photographs of the location of connectors and fasteners before dismantling.
Pay special attention steering wheel position. B Almera Classic control unit SRS located under the center console and can be accidentally touched when removing the airbag. If you have not previously worked with passive safety systems, we recommend using service manual for your modification (for example, for engines QG15DE or CD20 schemes may differ).
⚠️ Attention: Never test airbag circuits with a multimeter in continuity mode! Even minimal current can trigger the squib. Use only resistance measurement mode with limit 20 kOhm.

Step 1: Removing the plastic dashboard trim
Passenger airbag Nissan Almera Classic attached to the metal frame of the dashboard through a plastic cover. To remove it:
- Open the glove compartment and remove all contents. At the bottom of the glove compartment, find two screws for a Phillips screwdriver - they need to be unscrewed.
- Gently pull the glove box cover towards you; it is held in place by plastic clips. Do not use excessive force - the clips break easily.
- Remove the decorative cover above the glove box (it is secured with latches). Hidden underneath are two more screws that secure the cushion cover.
This will give you access to the four airbag mounting bolts (two on each side). In some trim levels Almera Classic (for example, with an air conditioner), additional removal of the air duct may be required. To avoid damaging it, use plastic spatulas to pry off the clips.
☑️ Preparing to remove the pillow
Step 2: Disconnecting the pillow's power connector
Airbag power connector (yellow) is located on the back side of the lining. B Nissan Almera Classic he has special lock, which blocks accidental disconnection. To unlock it:
- 🔌 Click on plastic latch (usually orange or red) and pull the connector to the side.
- 🔍 Check the contacts for oxidation. If they are dirty, clean them alcohol solution (do not use abrasives!).
- 📏 Measure the resistance between the contacts
1And2connector. In a working pillow it should be within2–4 ohms.
If the resistance is 0 ohm or ∞, this indicates squib malfunction or circuit break. In this case, the pillow must be replaced, and the unit SRS reflash (otherwise the lamp Airbag will remain on continuously).
| Wire color | Purpose | Resistance (normal) |
|---|---|---|
| Yellow | Power (+) | — |
| Black | Weight (–) | — |
| White/red | Trigger signal | 2–4 ohms |
| Green/black | Diagnostics | ∞ (open) |
⚠️ Attention: After disconnecting the connector do not touch the contacts bare hands. Static electricity can damage the electronic components of the pillow. Use an antistatic wrist strap or at least touch a metal part of the body before working.
Step 3: Removing the airbag
When the connector is disconnected, you can begin to dismantle the pillow itself. B Nissan Almera Classic it is secured with four turnkey bolts 10 mm. Process Features:
- 🔧 Bolts often stick, so treat them before unscrewing WD-40 or similar lubricant.
- 📦 The pillow is attached to a metal frame that remains on the dashboard. Do not try to remove it - it is part of the body.
- 🔄 After removing the bolts, carefully pull the pillow towards you. It should come out effortlessly. If you feel resistance, check that all fasteners are unscrewed.
Place the pillow on a flat surface face up. Do not place it on its side or down as this may cause the squib to become deformed. If you plan to reuse the pillow, wrap it in bubble wrap and store it in a dry place at 15–25°C.
If the cushion mounting bolts are heavily rusted, do not try to remove them by force. It is better to drill them out with a drill with a thin drill bit (⌀3 mm), and then screw in new bolts with M6 threads.
Diagnostics after removal: why does the Airbag light come on?
If after reassembly the light on the dashboard comes on Airbag, this indicates an error in the system SRS. B Nissan Almera Classic most common reasons:
- 🔌 Incorrect connector connection — check whether the lock is fully latched.
- 🔧 Wiring damage - Inspect the harness for fractures or exposed wires.
- 💻 Reset errors - even after correct connection, it may be necessary to reset the fault code via a diagnostic scanner (for example, Launch CReader).
To read errors, connect the scanner to the connector OBD-II (located under the steering wheel) and follow these steps:
1. Включите зажигание (не запуская двигатель).2. В меню сканера выберите SRS/Airbag.
3. Считайте коды ошибок (например,
B1015— обрыв цепи подушки пассажира).
4. Устраните неисправность и сбросьте ошибки через сканер.
If the lamp continues to light, it may be damaged. SRS control unit (located under the center console). In this case, it will need to be replaced or reflashed in the service.
What to do if the airbag deployed accidentally?
If the squib fires (even partially), the airbag must be replaced completely. Powder from the squib is toxic - ventilate the interior and use a respirator when cleaning. The SRS unit will also require diagnostics, since the operation is recorded in its memory.
Installing a new pillow and reassembling it
When installing a new airbag, follow the reverse procedure, but keep in mind a few nuances:
- 🔄 Check compatibility - pillows for Almera Classic with engines
GA16DEAndQG18DEmay differ in connectors. - 🔧 Bolt torque —
8–10 Nm. Undertightened bolts will lead to vibrations, and overtightened bolts will lead to deformation of the fasteners. - 🔌 Test after assembly — before connecting the battery, make sure that all connectors are secure and the wiring is not pinched.
After connecting the battery, turn on the ignition and wait until the lamp goes out Airbag (usually it takes 5–7 seconds). If the lamp flashes or stays on, repeat the diagnostics.
Never use airbags from other Nissan models (such as Primera or Sunny), even if they look similar. Differences in squib resistance may result in false triggering.
Common mistakes and how to avoid them
Even experienced professionals make mistakes when working with SRS-systems. Here are the most common ones for Nissan Almera Classic:
| Error | Consequences | How to avoid |
|---|---|---|
| Operation without disconnecting the battery | Airbag deployment, SRS unit damage | Always remove the terminal and wait 10 minutes |
| Using non-original bolts | Vibrations, spontaneous unscrewing | Use bolts with M6 threads and spring washers |
| Checking the circuit with a multimeter in continuity mode | Triggering of the squib | Measure only resistance at the limit of 20 kOhm |
| Installing a pillow without checking the connector | Short circuit, SRS error | Clean contacts with alcohol before connecting |
If you are not confident in your abilities, it is better to contact the service. Airbag removal cost Nissan Almera Classic amounts to 1 500–3 000 ₽ (depending on the region), which is cheaper than repairing after errors.
