1 Remote control key

When the "lock vehicle" button is pressed the remote control key sends a radio frequency and infrared signal to the corresponding receivers in the vehicle. These receive the signal and transfer the contents on to the electronic ignition switch (EIS) control module (N73) via the CAN bus. The EIS checks the code for access authorization. If the check indicates that the code is valid, the EIS transmits the "lock" command to the PSE control module (combined) (A37) via the CAN bus. The PSE control module

then locks the doors pneumatically.

In addition the interior switches, i.e. the interior switch (CL) (S6s1) and remote trunk release switch (N71s15) are disabled.

When the remote control key is inserted into the electronic ignition switch (EIS) control module (N73) after locking, the interior switches are enabled again. The central locking is then in the same state as after locking with the interior switch (CL) (S6s1).
