A remote vehicle diagnostics, monitoring, configuration and reprogramming tool is provided. The system includes a fleet of vehicles equipped with wireless mobile communications means that enable fleet managers to remotely diagnose, monitor and reprogram vehicles in their fleet via an Internet Web-based browser environment. Each vehicle within the fleet is equipped with a smart device that is coupled to the data bus within each vehicle. Date commands relating to the vehicle's parameters (e.g., diagnostic parameters such as max road speed, engine RPM, coolant temperature, air inlet temperature, etc.) are sent and received using satellite and terrestrial wireless communications technology. The invention allows users to remotely perform total fleet logistics and eliminates (or reduces) the need to physically bring fleet vehicles to a repair, maintenance or configuration facility.
