Installation of audible warning and belt sensor

[franbmx]

Do you know how to install the audible seatbelt warning for the driver and passenger?

I have mounted the two pretensioners that have two cables and the passenger weight sensor and I have activated opcom the two audible warning options and the tachometer icon in the airbag section but it does not work for me.

Would I miss something else?

It is an astra h gtc.

Do the belts have a control unit?
Or is it the airbags?
Do you think it could be the problem?

That my switchboard does not come prepared for that extra?

Hi there! I am also interested in this modification, since my Astra came with the seat belt recognition disabled from the airbag module. But, since the airbag ecu is locked, I cannot modify the configuration in any way. I know for sure that hardware wise I have all the equipment because I wrote on the EEPROM a dump from a car that had this feature activated and it worked, but unfortunately I cannot leave it like that since 2 other settings are not aligned with what my car has.. Does anyone have any idea on how to unlock the airbag ECU? Or which memory adresses from the EEPROM dump contain the configuration? Thanks!
