Alarm




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.

Tracking Initiated by Owner
The owner himself can initiate tracking of the vehicle by contacting the Service Center.

The following takes place:
- The owner contacts the Service Center and identifies himself with a password.
- The Service Center establishes contact with the vehicle, that is, with the PHM, which enters Volvo On Call Plus service mode.
- The PHM sends a continuous signal regarding, for example, the geographical position of the vehicle. How often this is done, is determined by a message which is sent from the Service Center to the PHM. The time interval may differ, for example, from every 30 minutes to once a week.
- The tracking time is determined by the customer and the Service Center.
- The loudspeaker is switched off.
