Central locking emergency opening, function - GF80.20-P-4013S

MODEL 215, 220 

The emergency unlocking feature unlocks the vehicle doors after an accident.

The PSE control module (combined) (A37)  is equipped with a crash sensor. When the vehicle is decelerated with a force of more than 6 g the emergency unlocking feature is triggered.

Deceleration of 6 g corresponds to an impact against a solid wall at a speed of approx. 25 km/h.

After a waiting time of eight to eleven seconds the PSE control module (combined) (A37)  pneumatically unlocks all  of the vehicle doors  . Moreover, the remote trunk release switch (S15/1)  in the trunk lid lock and, via the CAN bus, the remote trunk release switch (S20/1s6)  on the driver's door are enabled.

The anti-theft alarm (ATA)  is not deactivated! 

The emergency unlocking feature is canceled, i.e. the previous locking status is restored if circuit 15 OFF is recognized for at least two seconds.

The emergency unlocking feature has priority over all other central locking functions.
