The system has its own SDS (Self Diagnostic Software) to perform routine checks and ensure sensors and internal circuits are working properly. Should the system suspect a sensor is being tampered with it will go on high alert, notify the User and carry out user-programmed actions. The User can then telephone the system and listen to verify an intrusion. The system will also give you early warning of component failures in your vehicle - as the system interfaces with central locking, lights, horn, electric windows etc it will notify you if anything is not working correctly.
