General 

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

Vehicle remote locking function sequence 

The CAC checks the query and customer legitimization and if the data matches up a "vehicle remote locking request" is sent to the vehicle.

The "vehicle remote locking request" is received by the communication module integrated into the emergency call system control unit in the following way:

• Multifunction antenna (A28/11)
• Discrete line
• Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada
• Discrete line

After receiving the "vehicle remote locking request", the emergency call system control unit sends the request in the following way to the electronic ignition lock control unit (N73):

• Diagnostic CAN
• Front SAM control unit with fuse and relay module (N10/1)
• Interior 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 CAC in the same way as for the "vehicle remote locking request".

If the vehicle doors and the trunk lid have been locked, feedback is also sent to the CAC in the same way as for the "vehicle remote locking 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.

In the event of a multifunction antenna malfunction (e.g. defective because of rollover) the emergency call system control unit automatically uses the emergency call system antenna (A2/52) to transmit mobile phone signals or data.
