Abstract

A system for storing the location of a vehicle during an error condition is provided. The system includes one or more vehicle electronics devices that include memory, and are configured to detect an error condition associated with the vehicle electronics device(s). The system also includes a location determination device coupled to the vehicle electronics device and configured to determine a vehicle location and provide information indicative of the determined vehicle location. The vehicle electronics device(s) are configured to store vehicle location information provided by the location determination device in memory. The stored vehicle location information is indicative of the location of the vehicle at the time an error condition is detected by the vehicle electronic device. Methods for storing the location of a vehicle during an error condition are also provided.
