Abstract
A vehicle telematics device for a vehicle that includes an electronic processor, a wireless chipset for wireless communication to and from the vehicle, and a bus interface for receiving bus messages from a communications bus in the vehicle. The vehicle telematics device includes computer readable memory storing program code that, upon execution by the processor, causes the vehicle telematics device to: (a) monitor for messages received by the bus interface from the communications bus; (b) detect a communication failure of the communication bus based on the monitoring; (c) determine a vehicle movement that is indicative of a vehicle crash; and (d) initiate a communication with a remote facility in response to both the detection of the communication failure and the determination of the vehicle movement that is indicative of a crash a notification.
