Terminology Definition
Adaptation to Convenience System Central Control Module
Adaptation of the remote transmitter is the first step to activating the convenience functionality (i.e. lock / unlock, memory seats) of the key Fob. This
can only be done via Diagnostic tool VAS 5051/5052. When adapting a remote transmitter, it will automatically be synchronized. During adaptation of
the remote transmitter, the following occurs:
^ The convenience system central control module writes an association into the remote transmitter. This association identifies each individual remote
transmitter.
^ The convenience system central control module simultaneously learns the individual remote transmitters fixed code.
Adaptation of a remote transmitter may only be lost if a non-adapted remote transmitter is adapted to a position that an existing remote transmitter is
already adapted to. There are 4 possible positions available.
When adapting a remote transmitter to a position where an existing remote transmitter already is adapted, the adaptation of the existing remote will be
erased.
Synchronization
A remote transmitter must be adapted before it can be synchronized.
Diagnostic tool VAS 5051/5052 is not necessary to synchronize a remote transmitter.
Only a synchronized remote transmitter will operate the door locks.
Synchronization of the remote transmitter is a security feature. There is a variable code in both the convenience system central control module and in the
remote transmitter. When synchronization occurs the variable codes between the two components are aligned.
A remote transmitter will lose its synchronization if the vehicle battery or remote transmitter battery are replaced or are low on power.
Loss of remote transmitter synchronization will not affect the adaptation of the remote transmitter.
