General
The vehicle remote locking function enables the customer to lock his/her vehicle remotely if he/she has forgotten to lock the vehicle.

Function sequence
The service center checks the query and customer legitimization and if the data matches up a "Vehicle remote door lock request" is sent to the vehicle.
The "vehicle remote door lock request" is received by the communication module integrated into the emergency call system control unit via the following route:
- Emergency call antenna (A2/52), model 216
- Telephone and GPS roof antenna (A2/49), model 221
- Frequency switchover control unit (N96), model 221 with code (389) Mobile phone preinstallation with universal interface, USA/Canada
- Direct line

The emergency call antenna is integrated in the GPS antenna (A2/49a2) in model 216.

After receiving the "Vehicle remote door lock request", the emergency call system control unit transfers the request to the EIS [EZS] control unit via the following route:
- Diagnostic CAN
- Central gateway control unit (N93)
- Chassis CAN

The EIS [EZS] control unit then checks whether the locking of all vehicle doors and the locking of the trunk lid is possible. If it is possible to lock all the vehicle doors and the trunk lid, then the EIS [EZS] control unit initiates the locking of all the vehicle doors and the locking of the trunk lid. If not, feedback is sent to the service center in the same way as for the "vehicle remote door lock request".
If the vehicle doors and the trunk lid have been locked, feedback is also sent to the service center via the same route as the "vehicle remote door lock request".

After receiving the feedback, the CAC notifies the customer of the vehicle remote locking result (locked: yes or no) via the phone call which is still active

If the telephone and GPS roof antenna, model 221, or the emergency call antenna, model 216, fails (e.g. malfunction caused by rollover) the emergency call system control unit transmits and receives the mobile radio signals and data via the following route in order to transfer mobile radio signals and mobile radio data:
- Direct line
- Emergency call system antenna splitter (A2/25)
- Direct line
- Emergency call system left backup antenna (A2/54)
- Emergency call system right backup antenna (A2/55)
