MODEL 171.4 

Rear end collision 

In the event of a rear end collision, the restraint systems control unit (N2/7) evaluates the data of the internal sensor.

The following information is also evaluated for recording the situation in the vehicle interior:

Left front seat belt buckle status 

If the driver seat belt buckle restraint systems switch (S68/3) detects that the belt latch is not inserted into the seat belt buckle, then the left front emergency tensioning retractor unit is not triggered.

Right front seat belt buckle status 

If the front passenger seat belt buckle restraint systems switch (S68/4) detects that the belt latch is not inserted into the seat belt buckle, then the right front emergency tensioning retractor unit is not triggered.

Depending on the severity of the impact and the situation in the vehicle, the following squibs for the corresponding restraint devices are actuated:

• Drive buckle ETR (Emergency Tensioning Retractors) squib (R46)
• Front passenger ETR (Emergency Tensioning Retractors) squib (R46/1)
