Installing and removing airbags on a Lada Granta car
Of course, quite a large number of people are trying to compare two models of domestic vehicles. Firstly, this is a car with the beautiful name “Lada Kalina”. Secondly, this is also a domestic vehicle under an equally beautiful name - “Lada Granta”. It would seem that the models were produced at the same factory, and the elements are similar, but according to experts and the creators of the car, they are the complete opposite of each other. Actually, their internal structure speaks about the same thing.
In addition, it is worth noting that if we touch on the topic of safety on the country’s roads, then the second model is tens of times superior to the first. Perhaps this is why the popularity of the Lada Granta is so great. For example, let's look at the safety level regarding your vehicle's airbags. The model called “Lada Granta” was equipped at the factory with nothing more than airbags that inflate during a collision. In addition, there is a side airbag inside the cabin.
Of course, no one really cares about the airbag; it doesn't need to be cleaned, removed or changed unnecessarily. But you must admit that situations may arise that the driver or owner of the vehicle will have to remove the steering wheel, or simply disassemble it. What to do with the airbag in this situation?
Remember that before you start removing the steering wheel, and therefore disassembling the airbag, which was installed and mounted in it according to technical standards. First, you need to turn off your vehicle's engine ignition.
Secondly, it is completely natural to stop your vehicle. Thirdly, you need to open the hood of your car, and in our case, it is a Lada Granta, and pull out the negative terminal of the car battery. Why, you ask? All for the same thing, that no short circuit occurred. If you do not do this and a short circuit still occurs, then most likely you will need to completely change the on-board computer, which will lead to large financial costs.
Please pay attention to one more important point in this procedure. Look carefully at the position in which the wheels of your vehicle are standing (which means they have already stopped)
Remember that they must be located in a straight position.
Now you can proceed to the next stage of working the steering wheel of your vehicle. It is necessary to unscrew several bolts that are located on the side of the car's steering wheel. Remember that they are the ones that serve as fastenings for the gas generator module, which together with the steering wheel represent a single picture, or, to be more precise, a single structure. In the event that the module does not work, it must be placed on a flat surface, so that its cover is positioned in the upward direction.
After this, you need to unscrew those screws that are responsible for fastening the steering shaft, and using a Phillips screwdriver you can perform this procedure. Remember that you must remove the O-ring along with the switch. And only after this it is necessary to carry out work that is associated with the process of disconnecting the harnesses and wires of the on-board computer network.
The final stage of the disassembly technique will be to remove the steering wheel shaft; this can be done using a flat-head screwdriver. You can then remove the airbag and, if necessary, replace it with a new airbag. Then install it in its “native” place
Now note that the wheels of your vehicle are level and the negative terminal of the car battery has been removed, the first thing you need to do is install the steering shaft and connect it to the “original” device. Then it is fashionable to dismantle the red transport key
After this, you need to install the washer system levers, as well as the alarm system of your vehicle. Once everything is done as described above, all you have to do is thread the two wires through the hub at the front of the steering wheel and carry out the final process of assembling the steering wheel in the reverse order of how we disassembled it.
Passenger airbag
The passenger airbag module (PAIBP), Figure 13, consists of a gas generator 1, a housing 3, with an airbag folded in it, and a facing cover 7.
The gas generator consists of a housing filled with compressed inert gas and a pyrotechnic substance, and an igniter fuse.
An igniter is a device with electrical resistance and a pyrotechnic substance.
After receiving an electrical signal from the control unit, the electrical resistance heats up and ignites the pyrotechnic substance of the igniter, followed by ignition of the bulk of the pyrotechnic substance of the gas generator.
Removing the passenger airbag
We remove the instrument panel as described in the article - How to remove the instrument panel of a Lada Granta.
Disconnect block 1, Figure 14, of the instrument panel wiring harness from the MNPBP.
Using a 13 socket, unscrew two bolts 4
Press the clamps 5, disconnect and remove the passenger airbag module
Place the failed module on a flat surface with the facing cover facing up.
Installing the airbag module
Before installing the module, you must ensure that there is no damage.
Install the airbag module in reverse order
The tightening torque of the two bolts securing the airbag module is 13 – 15 Nm (1.3 – 1.5 kgcm).
