Crash Unlock

Crash Unlock
In the event of a crash, the safety and gateway module (SGM) releases the central locking system (ZV) via the bus network at terminal R or 15.
The ZV assumes crash mode even when the central locking was already unlocked. Crash unlock is disabled when the vehicle status is secure lock.
Crash mode is released when an unlock/lock request is made. This corresponds to deactivation of crash mode.
