1. A method of remote communications with an on-board diagnostics (OBD) system of a vehicle, the method comprising:
connecting a vehicle communications device to a connector of a vehicle's OBD system;
connecting a remote tool side communications device to a connector of a vehicle tool device;
establishing a network communications link between the vehicle-communications device and a remote communications device;
receiving communications at the vehicle side communications device or tool side communications device from the respectively connected vehicle's OBD system or tool device through the respective connector of the OBD system or tool device;
analyzing a bit stream of the received communications over an interval of time;
estimating widths of one or more bit pulses based on the analyzing of the bit stream;
determining a bit rate of the OBD system based on the estimated widths of the one or more bit pulses;
based on the determined bit rate of the OBD system, establishing bidirectional communications between the OBD system and the tool device using the established network communications link between the vehicle-communications device and the remote communications device.
