General 

The vehicle remote locking function is part of the Telematic Alarm Identification on Demand (emergency call system) (TELE AID). The customer has forgotten to lock the vehicle. The customer can initiate the remote vehicle locking via the service provider.

The following function requirements must be met:

• C. 30 ON
• The TELE AID has been authorized by the service provider
• A cellular mobile telephone network in adequate quality is available
• To activate the service, the customer requires the Personal Identification Number (PIN) and the vehicle model

How to proceed 

The customer contacts the service provider via telephone. The Customer Assistance Center (CAC) technician then requires the user name and PIN, which were assigned during authorization of the TELE AID, as well as the vehicle model to be able to check the authorization for vehicle remote locking. The CAC employee transmits the "Remote Door Lock" message to the vehicle. The vehicle checks the request and transmits a message to the service provider that contains the information whether or not it was possible to lock the vehicle. Then the CAC employee informs the customer of the result.

Function sequence 

The CAC employee checks the customer request made over the phone and transmits the Remote Door Lock request (vehicle remote door locking) to the vehicle. The emergency call system control unit (N123/4) receives the "Remote Door Lock" message depending on the mobile phone network quality over the frequency switchover control unit (N96) and, for model 221, over the telephone and GPS roof antenna (A2/49) or, for model 216, over the telephone and GPS antenna (A2/49) or over the emergency call system antenna splitter (A2/25) and over the emergency call system left backup antenna (A2/54) as well as the emergency call system right backup antenna (A2/55), and forwards this message over the diagnostic CAN to the central gateway control unit (N93).

The central gateway control unit transmits the request to the EIS control unit (N73) via the chassis CAN. The EIS control unit checks whether the vehicle can be locked and transmits the result to the central gateway control unit. The central gateway control unit forwards the result to the emergency call system control unit. The emergency call system control unit transmits the result to the service provider via the cellular mobile telephone network. Then the CAC employee informs the customer of the result.
