Abstract
An odometer monitor for monitoring the connectivity status of a mobile data terminal to a vehicle is a software module defined in a data processor of a vehicle tracking device. The monitor is operable to listen for arrival of successive timed poll events from a mobile data terminal connected to a vehicle, listen for arrival of and storing each of successive odometer update values from a vehicle information bus of the vehicle that corresponds to arrival of each of the successive timed poll events, compare next odometer update values to last stored odometer update values, calculate the distances between the compared odometer update values, make a determination of connectivity status of the mobile data terminal relative to the vehicle based on whether or not the values of the calculated distances ascend to above the value of a preset maximum distance, and report the connectivity status to the mobile data terminal.
