Automatic locking, function - GF80.20-P-4009GH

MODEL 163 up to 30.11.99 

The all-activity module (AAM) (N10)  locks all door groups electrically as soon as the vehicle speed exceeds a threshold value of approx. 5-10 km/h.

The AAM recognizes when the threshold is exceeded by evaluation of the speed signal from the CAN data bus.

The vehicle can be unlocked  again by shutting off the engine (circuit 15c)  or with the central locking switch (S21s10) 

IMPORTANT This function can be deactivated with the HHT  .
