Abstract: A non-integrated monitoring device and method for monitoring a subject vehicle includes monitoring, via a non-integrated sensor, a physical parameter being emitted from the subject vehicle. The physical parameter being emitted from the subject vehicle is analyzed to determine a dynamic signature for the subject vehicle. A baseline signature for the subject vehicle is obtained, and compared to the dynamic signature for the subject vehicle. Occurrence of a fault in a subsystem of the subject vehicle is detected based upon the comparing of the baseline signature for the subject vehicle and the dynamic signature for the subject vehicle, and the occurrence of the fault is communicated to an operator of the subject vehicle.

Abstract: A system and method for providing enhanced diagnostic and maintenance reporting for a vehicle over a wireless communication system. When receiving a telephone call from a subscriber requesting diagnostic assistance, a data connection is established between a call center and the subscriber's vehicle, and the needed diagnostic data is obtained by the call center so that an advisor at the call center can provide the requested assistance. The established data connection is also used to obtain additional data from the vehicle related to vehicle maintenance and this additional data is used by the advisor to provide an enhanced response to the subscriber.
