Конечно есть связь - без пристегнутого ремня подушка становится опасна (лирическое отступление), На ремне безопасности установлен SEAT BELT TENSIONER и если что, то:
The seat belt system incorporates Tensioner Modules.
They are integral to the seat belt retractors
and cannot be serviced. If found defective
they must be replaced.
ИЛИ:
BELT TENSIONER SYSTEM
At the onset of an impact event, each tensioner
uses a pyrotechnic device which is triggered simultaneously
with the airbags to rapidly retract the seat
belts. With the slack removed, the occupant’s forward
motion in an impact will be reduced as will the likelihood
of contacting interior components.
WARNING: WHEN THE FRONT AIRBAG IS
DEPLOYED, THE TENSIONER WILL HAVE
DEPLOYED ALSO, AND MUST BE REPLACED.
The ORC monitors the seat belt tensioner circuit
and reports active and stored Diagnostic Trouble
Codes (DTC’s) if any problem is found.
Once a vehicle has been in an accident, the tensioner
will have a “Gravel/Grinding“ sound to it after
the tensioner has been put into use. This must be
replaced along with any deployed airbags and broken
or damaged parts.
ИМХО - лучше заехать в сервис и считать код неисправности системы AIR BAG
