– Reading in position P of the automatic
transmission from the switch for gearbox
position P F305:
The signal is used to activate the integrated,
magnetic ignition key anti-removal lock. If the
vehicle battery is flat, the key can be removed by
pressing the mechanical emergency release.
– Reading in the information from the button for
access and start authorisation E408 (only for
vehicles with Advanced Key):
Fo r s a fe t y r e as o n s , t h e p o s i t i o n s o f t h e b u t to n fo r
access and start authorisation are evaluated by
the switch for access and start authorisation.

– Reading in the information from the antenna for
central locking and anti-theft warning
system R47:
The switch for access and start authorisation
passes the data, which the vehicle key sends via
remote control, on to the control unit for access
and start authorisation. The control unit
evaluates the data.
– Reading in the signal from the brake light
switch F (only for vehicles with Advanced Key):
To start the vehicle using the button for access
and start authorisation, the brake pedal must be
actuated.
– Exchanging data with the key using the
integrated read coil:
If a key is inserted into the switch for access and
start authorisation (= S contact on), the
electronics system transmits electric power into
the key via the read coil. The key then sends the
key identification into the switch via the
transponder and the read coil. This sends the
information to the control unit for access and
start authorisation.

– CAN Communication:
The control unit is a participant on
CAN Convenience. Data exchange between all
the components of the access and start
authorisation system is performed via the
control unit.
It is also the diagnosis interface for the
components involved. All data, e.g. code,
immobiliser data, etc. is stored in the control unit
for access and start authorisation.
– Reading in the P/N signal from the control unit
for automatic transmission J217:
The signal is used to activate the displays
relating to engine start in dash panel insert J285.
