When the alarm is tripped, contact is automatically established with the Service Center.

The following takes place: 

• CEM has triggered the alarm and, among other things, sent a signal to the UEM to activate the siren.
• In this position, UEM sends out a signal periodically on the CAN network about the fact that the alarm has been tripped.
• The PHM picks up the signal and automatically enters Volvo On Call Plus service mode.
• Contact is established with the Service Center after a certain period of time.
• The Service Center makes verbal contact with any driver, who then has to identify himself with a password. If the incorrect password, or no password is given, the owner is contacted.
• The owner obtains help from the Service Center on how to handle the matter, for example, reporting the theft to the police.
