This airbag has a seat belt opposite it. Therefore, for airbags of this type, a programmable restraint system for the seat belt is additionally configured.
Description
The cushion is installed in the dashboard opposite the front passenger seat. It includes:
- inflatable chamber with two sections;
- non-separable pyrotechnic gas generator with two igniters.
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. Be sure to lock the ECU with a scan tool before removing the passenger airbag module. In this case, all ignition circuits are blocked, and the airbag warning lamp on the instrument panel lights up.
To remove the passenger airbag module, the instrument panel must be removed.
Disconnect the connectors of both igniters and remove the mounting screws.
Attention! When the passenger airbag unit is triggered, the fastening elements are damaged or destroyed, the instrument panel must be replaced.
Don't forget to stick a label on the side of the new instrument panel stating that a child seat is not allowed on the passenger's seat back to the road (this label is included in the kit Stock no.: 77 01 205 442).
When the seat belt pretensioners or airbags are deployed, the computer will be completely locked out and the airbag warning light on the instrument panel will come on. In this case, the ECU must be replaced (under the influence of ignition energy, some components lose their rating).
Module installation
Attention! Follow the safety guidelines when removing or replacing the passenger airbag module.
The slightest deviation from these rules can lead to the failure of the pyrotechnic systems and even create a danger to the passengers of the car.
Proceed in the reverse order of removal, with obligatory observance of the tightening torques of the module fastening elements.
Replace the fastening clips 2 of the passenger airbag module.
Attention! There must be no foreign objects in the airbag installation area (screws, clips, etc.).
The tightening torque of the module fixing elements is 2 Nm.
Connect the wire block to the module, press the wire block until it locks into place and install the safety clip.
Stick a sticker indicating the work is done - blue.
Carry out a check with the diagnostic tool.
If all characteristics are within the normal range, unlock the computer.
Access to the igniter
Access to the igniter (airbags with two sections) or the intermediate connector 1 of the passenger airbag module for diagnostic purposes is provided through the glove box.
Remove the glove box cover, the connector is located on the right side of the dashboard (next to the optional fuse and relay box, if available).
