The electromechanical steering column lock was
integrated into the control unit for access and start
authorisation.
Functions
– Terminal control:
The control unit for access and start
authorisation puts the information about
terminal 15, 75x, 50, S and P on
CAN Convenience.
The control unit also activates the relays for
terminal 15 and 75x and passes the start request
signal on to the engine control unit.
– Locking the steering column:
The motor and gears for locking the steering
column are integrated into the control unit for
access and start authorisation.
The position of the lock is checked using two
integrated micro switches. Terminal 15 is only
switched on after the steering is unlocked fully.
– Immobiliser and component protection:
The control unit is the master for these
functions.
