Part of the car has 2 pillows, one of which (from the driver's side) mounted in the central part of the steering wheel, and the other in the ceiling part of the glove box. The system also includes a control and diagnostic unit mounted under the front panel in the center of the vehicle.
Driver side safety module
The module includes a packed cushion and an inflator (reactor), which is located under the pillow and is connected to it by a hole through which gas is supplied when a signal is received.
The signal is sent through a cable wound into a flexible spiral around the rudder shaft, regardless of the rudder angle. The pillow is inflated with nitrogen formed as a result of the reaction of copper oxide and sodium azide.
Passenger side safety module
The module includes an injection device (reactor), folded pillow, reactor and cladding panel.
The passenger airbag is much larger than the driver's airbag. The pillow is supported by a steel reactor vessel.
When inflating the pillow, the seam of the facing panel breaks.
Control and diagnostic unit
The unit provides power and deployment of the airbag even when the battery is disconnected.
The block checks the status of the security system. System warning lamp (AIR-BAG lamp) first lights up and goes out when the system is working.
If the system is faulty, the lamp remains on or flashes (or a beep sounds). In this case, the car should be immediately handed over to a car service for inspection.
Warning! Disabling the airbag system: Neglect of precautions can lead to accidental deployment of the air bag and serious injury.
When performing any work near the steering column or any unit of the system, it is necessary to disable the airbags.
Deactivating the airbag
1. Set the wheels to the straight ahead position and turn the ignition key to the LOCK position.
2. Disconnect the battery from the ground.
3. Start work after at least 2 minutes, necessary for the discharge of the capacitor.
When handling the pillow container, always hold the lined side of the container away from you. Do not lay the container with the lined side down. It is forbidden to measure the resistance of any unit of the pneumatic safety system, since the airbag may be triggered by an ohmmeter battery.
Disconnect the yellow airbag connector located under the steering column near the switch combination connector before welding (from the driver's side) or glove box (passenger side).
It is forbidden to throw away the container with the pillow.
