Notes on triggering logic when passenger seat occupied and child seat recognition sensor (B48) is not present
In the event of a minor accident in which the protective effect of the seat belts alone is sufficient, the ETR control module with airbag (N2/2) triggers only the driver (passenger) ETR when the 1st triggering threshold is exceeded and the driver (passenger) seat belt is buckled .
When the first triggering threshold is exceeded and the driver (passenger) seat belt is not buckled , the driver (passenger) airbag is always triggered.
When the 2nd triggering threshold is exceeded, the driver and passenger airbags are triggered if not already accomplished (see above).
The driver (passenger) side airbag is always triggered when the ETR control module with airbag (N2/2) recognizes a side collision.
