Nissan Almera G15 (2012–2018) equipped with a passive safety system SRS (Supplemental Restraint System), which includes front, side airbags and belt tensioners. However, owners often encounter problems: false alarms of the indicator SRS/AIRBAG on the dashboard until it is necessary to replace the squibs after an accident. In this article we will look at how to independently diagnose faults, reset errors and what to do when replacing pillows - without myths or cliched advice.

System SRS on Almera G15 sensitive to power surges, contact corrosion and even unqualified repairs. For example, after replacing the steering wheel or dashboard, the light may come on AIRBAG - this is a signal that the squib circuit is broken. We analyzed common errors (including B1018, B1034), collected data on spare parts compatibility and prepared step-by-step instructions taking into account the specifics Almera G15 (as opposed to universal manuals).

How the SRS system works on the Nissan Almera G15

B Almera G15 system SRS includes:

  • 🔹 Front airbags (driver + passenger) - triggered in the event of a frontal impact at a speed of >20 km/h.
  • 🔹 Side cushions (in front seats) - activated during a side impact.
  • 🔹 Belt tensioners — the belt blocks during a sharp jerk.
  • 🔹 SRS control unit (under the center console) - analyzes data from impact sensors and accelerometers.

Feature Almera G15: block SRS connected to CAN bus, so errors may appear if there are problems with the on-board network (for example, after “lighting up” from another car). Unlike Nissan Note or Tiida, there are no knee airbags, but there is a passenger seat position sensor - if it fails, the system may falsely detect the presence of a passenger.

Important: pillows disposable. Replacement required after tripping squib (and not the pillow itself, as many people think). For example, in the driver's steering wheel Almera G15 cartridge used 28510-4M00A, and in the passenger panel - 28510-4M01A. These parts are not interchangeable with other models Nissan!

📊 Have you encountered a burning AIRBAG light on your Almera G15?
  • Yes, after an accident
  • Yes, for no apparent reason
  • No, but I heard about the problem
  • I don't know what it is

Reasons for triggering the AIRBAG indicator

light bulb AIRBAG on the dashboard Almera G15 lights up when:

  • 🚨 Broken squib circuit (most often after repairing the steering column or replacing seats).
  • 🔋 Nutrition problems: power surges, dead battery, corrosion on the connectors of the SRS unit.
  • 🔧 Shock sensor malfunctions (located in the front side members). After an accident, they must be checked.
  • 💺 Passenger seat sensor failure (error code B1034).

A critical feature of the Almera G15: the SRS unit may freeze after disconnecting the battery for a long time (more than 30 minutes). In this case, you need to reset the errors through a diagnostic scanner, and not just remove the terminal!

Typical errors detected by the scanner:

Error code Description Possible reason
B1018 Driver's airbag squib circuit open The wire under the steering wheel or the squib connector is damaged
B1034 Passenger seat sensor malfunction Contact contamination or mechanical damage to the sensor
U1000 Lost communication with SRS unit Problems with the CAN bus or unit power supply
B1009 SRS Circuit Low Voltage Discharged battery or corrosion on ground
⚠️ Attention: If the dashboard flashes AIRBAG 5 times, and then lights up constantly - this is a signal about critical squib malfunction. It is prohibited to operate the car in this case: the airbag may work spontaneously!

How to reset AIRBAG error without a scanner

On Almera G15 reset error SRS The "old-fashioned" method (removing the battery terminal) will work only in 30% of cases. More often required sequence of actions:

  1. Turn off the ignition, open the hood.
  2. Remove negative terminal from the battery for 10 minutes.
  3. Reconnect the terminal, turn on the ignition (do not start the engine!).
  4. Press and hold the button TRIP RESET (on the dashboard) for 7 seconds.
  5. Turn off the ignition, wait 30 seconds, then start the car.

If the light bulb AIRBAG continues to burn - the problem is deeper. For example, after replacing the steering wheel with Almera G15 often required flashing the SRS unit (since the new steering wheel may have a different resistor in the steering column cable). In this case, you cannot do without diagnostic equipment.

Airbag diagnostics: step-by-step instructions

To check SRS on Almera G15 you will need:

  • 🔧 Multimeter (for checking circuits).
  • 🔍 Diagnostic scanner (for example, Launch CReader or ELM327 with support Nissan Consult).
  • 📋 Wiring diagram (can be found in the manual EWM51U0E for Almera G15).

Procedure:

  1. Connect the scanner to the connector OBD-II (located under the steering wheel, to the left of the brake pedal).
  2. Select protocol ISO 9141-2 or CAN (depending on the year of manufacture).
  3. Read errors from block SRS. If the scanner shows U1000 - check CAN bus (maybe the problem is in the block BCM).
  4. To check the squibs: 
    1. Отключите аккумулятор.

    2. Снимите обшивку рулевой колонки (водительская подушка) или бардачок (пассажирская).
    

    3. Мультиметром замерьте сопротивление на разъёме пиропатрона — должно быть 2–4 Ом.

If resistance 0 ohm - short circuit if ∞ - break. In both cases, the squib cartridge needs to be replaced.

What to do if the scanner does not see the SRS unit?

The problem may be a damaged CAN bus or lack of power to the unit. Check the fuse SRS (10A, located in the mounting block under the hood, position No. 17). If the fuse is intact, look for a break in the wiring harness between the SRS unit and the OBD-II connector.

Airbag replacement: nuances for Almera G15

After an accident or airbag deployment Almera G15 replacement required:

  • 🔧 Squib (not the pillow itself!).
  • 🚗 Shock sensors (if they worked).
  • 🔌 Steering column cable (if damaged).

Important: original squibs for Almera G15 are supplied only complete with a pillow. However, you can use analogues from Renault (For example, 28510-4M00A interchangeable with 8200830930 for Renault Logan). But this will require SRS unit firmware to new parameters!

Instructions for replacing the driver's airbag:

  1. Disconnect the battery, wait 10 minutes (to discharge the capacitors in the SRS unit).
  2. Remove the steering wheel (unscrew the nut on 36 mm, having previously marked the position of the steering wheel with a marker).
  3. Disconnect the airbag connector (yellow lock - push up!).
  4. Install a new squib, connect the connector.
  5. Reassemble in reverse order, reset errors through the scanner.
⚠️ Attention: When replacing the passenger airbag with Almera G15 be sure to check seat weight sensor (located under the pillow). If it is damaged, the system will generate an error B1034, even if the airbag is working properly.
💡

Before installing a new pillow, clean the connector contacts with alcohol - this will prevent false alarms due to oxidation.

Common mistakes when repairing SRS and how to avoid them

Owners Almera G15 often make mistakes that lead to the light bulb going off again AIRBAG:

  • ❌ Ignoring the error U1000 - this is a signal of problems with CAN bus, and not with the pillow itself. Unit diagnostics required BCM.
  • ❌ Use of non-original squibs without flashing the SRS unit. For example, Chinese analogues may have a different resistance, which will cause an error B1018.
  • ❌ Incorrect steering wheel installation — if the marks do not match, the rotation angle sensor will work and the SRS unit will block the airbag.

Another typical problem: after replacing the front bumper (for example, after an accident), they forget to check shock sensors in the spars. They may be damaged, but this is not noticeable externally. As a result, the system SRS remains inoperative, although the light does not light!

💡

If the AIRBAG light does not go out after repair, check first SRS fuse (10A) and block mass (black wire on the body under the center console).

FAQ: Frequently asked questions about Almera G15 airbags

Is it possible to drive if the AIRBAG light is on?

Technically yes, but airbags disabled. In the event of an accident, they will not work, which increases the risk of injury. If the light comes on for no reason (no accident, no repairs), check the fuse and contacts of the SRS unit. If the error returns after resetting, diagnostics are required.

How can I check if the airbag has deployed before?

Inspect:

  1. Steering wheel - if the airbag deployed, there will be signs of a tear on it (even if it was replaced).
  2. Glove compartment (passenger airbag) - deformed lid or traces of glue.
  3. Label on the back of the pillow - if it is torn, the pillow has worked.

Also check the SRS unit for errors - if the airbag deployed, there will be a record there.

Is it possible to disable the passenger airbag for a child seat?

On Almera G15 no mechanical switch passenger airbags. The only way is to disable it programmatically through a diagnostic scanner (for example, Launch X431). However, this breaks the factory settings and may lead to errors. An alternative is to use a child seat with permission for installation in the front seat (according to GOST R 41.44-2005).

What should I do if the AIRBAG light comes on after replacing the steering wheel?

The reason is a mismatch in the resistance of the steering column cable. On Almera G15 the original cable has resistance 2.5–3.5 Ohm. Solutions:

  1. Install the original cable (28531-4M00A).
  2. Flash the SRS block for a new resistance (specialized software is required).
  3. Check if the wires are mixed up when connecting (pins 1 and 2 on the connector should go to the squib).
Where is the SRS control unit located on Almera G15?

Block SRS located under the center console, next to the gearshift lever. To get to it:

  1. Remove the plastic trim around the gearshift lever.
  2. Unscrew the 2 bolts securing the block (for Torx T20).
  3. Disconnect the connector (the lock is orange, press down).

Be careful: the unit is afraid of static electricity!
