(vehicles without power
windows), On Board
Diagnostic (OBD)

Functional description

The locking units located in the doors (door

lock) have an electric motor.

The motor locks the door and also takes

care of the "Safe" condition, i.e. after locking
at an external lock (door lock, tailgate, radio
remote control) the vehicle is protected
against theft and can no longer be unlocked
from the interior. The feedback on the
respective condition in control module
occurs via the contact switch in the locking
unit.

All the known convenience functions can be

performed with the electric convenience
system, interior lights control, ATA with
interior monitoring and the radio remote
control.

If the Airbag Control Module is triggered, a

signal is sent to the convenience control
module to unlock the doors.
