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

MODEL 203.0/ 2/ 7 

The "Emergency opening" function unlocks the vehicle doors after an accident.

The corresponding signal comes from the

• restraint system control unit (N2/7) (up to 23.04.04) and
• rear SAM control module with fuse and relay module (N10/2) (integrated crash sensor).

The "emergency opening" function has priority over all other central locking (CL) functions

When a crash is recognized the rear SAM control module with fuse and relay module (N10/2) transmits an unlock command to the left front door control unit (N69/1), the right front door control unit (N69/2), the left rear door control unit (N69/3) (only model 203.0/2) and the right rear door control unit (N69/4) (only model 203.0/2) after a waiting time of 8 to 11 s via the controller area network bus class B (interior compartment) (CAN-B).
