Description
The side airbag module is installed in the backrest of the front seat on the door side.
It includes:
- inflatable chamber;
- non-separable pyrotechnic gas generator with igniter.
When deployed, the airbag breaks the padding and unclenches the upholstery fabric fasteners.
Note. This system is activated when the ignition is switched on.
Removing the module
Attention! It is forbidden to carry out any work on pyrotechnic systems (seat belt pretensioners or airbags) near a heat source or an open flame, as there is a risk of their operation.
Before working on the backrest or removing a seat equipped with a side airbag, be sure to lock the computer using the diagnostic tool. In this case, all ignition circuits are blocked, and the airbag warning lamp lights up on the instrument panel (with the ignition on).
When removing the seat, be careful not to disconnect the connector to avoid electrostatic discharge which could cause the airbag to deploy.
Disconnect the battery.
Remove the seat assembly using tool E1. 1584 and back upholstery.
Disconnect the connector and free the wires of the airbag module, including the wire connecting to «weight» (mark the laying and attachment points of the wires).
Attention! If the system has never activated and needs to be reinstalled after removal, do not deploy the airbag, as its airbag is folded in a special way.
Take out a clamp 1 and take a pillow of safety.
Attention! Disposal of a non-deployed side airbag, see section «Deactivation procedure».
When the seat belt pretensioners or airbags are deployed, the computer is completely blocked and the airbag warning lamp on the instrument panel lights up. In this case, the side impact sensor and the ECU must be replaced (under the influence of ignition energy, some components lose their nominal characteristics).
Module installation
Attention! When the passenger airbag module is triggered, the fastening elements are damaged or deformed, the seat reinforcement must be replaced:
- install the airbag module to the seat frame;
- install clamp 1 supplied with the module;
- make sure that the connection wire with «weight» correctly connected to the airbag module (depending on configuration);
- lay the wires under the seat cushion as before, paying attention to the correct laying and attachment points;
- reconnect the connection wire to «weight» and check that the connector is secure.
Install the seat upholstery.
Install the seat on the car and connect all the connectors.
Carry out a check with the diagnostic tool.
If all characteristics are within the normal range, unlock the computer.
Attention! The slightest deviation from these rules can lead to the failure of pyrotechnic systems or to their spontaneous operation.
