General Description

Since the 1996 model year, North American automobiles have been required to provide an OBD, or On Board Diagnostics, port for the connection of test equipment.

Data is transferred serially between the vehicle and the external equipment using this connection, in a manner specified by the Society of Automotive Engineers (SAE) standards.

In addition to operating at different voltage levels, these ports also use a data format that is not compatible with the standard used for personal computers.

Key Features

such as RS232 handshaking, variable baud rates, etc. , have not been implemented. In addition, this device is only able to communicate using the 10.4KHz J1850 VPW protocol that is commonly used in General Motors and some Daimler Chrysler vehicles.
