The OBD port can found on the dashboard near the steering wheel of every car. The position of the port varies based on the manufacturer and is normally hidden in a blind spot for aesthetic reasons.

Then the UART board is connected to a computer where the communication takes place through the Tx, Rx and Ground pins and normal data type will be with baud rate in which there will be 8-data bits and 1 stop bit with no parity. We can then use any serial communication software like putty or even Arduino to speak with the car though AT commands.

Each AT command has a specific task to perform or returns a specific value. You can learn more about interfacing through the sparkfun hookup tutorial which explains how the connection should be made and initiated.

Previously they were black in color and now they are green. If you have a black cable, you will find that it will not physically fit into the green diagnostic port; this left technicians with new many questions, including:.

All of these are very good questions but before we can answer those we need to dig a little deeper and explain why the change occurred. You will also see this new green connector referred to in several different ways:.

The adapter connectors on trucks have been evolving since trucks first went electronic.

We have a very popular blog post that goes into the history of the first two setups and explains J and J Essentially, trucks have gotten more and more complicated-there are more computers, more wires, more sensors, and more technology on trucks.

To further explain this, kbs and kbs are the speeds at which messages are broadcasted on the vehicle. There can only be one speed per datalink, so if any devices truck vs adapters on the datalink are set at different rates the entire datalink will crash.

To make things more confusing, in we started to see the introduction of multiple CAN channels. Think of a CAN channel as its own network on the vehicle, and it is running at the kbs speed. Well, even though the speeds are greatly increased there is still a LOT of traffic going through it with the number of sensors and ECUs.

For this reason, the introduction of multiple CAN channels came to be. Normally you will find all your traffic for powertrain on CAN1, however that changed for the first time in This is when Peterbilt, Kenworth, and Volvo decided to move the powertrain traffic over to CAN3, which now created a problem. Since the design change was made on the diagnostic ports on the commercial trucks, all diagnostic cables also went through a design change. You will notice in the picture below that the pin at the top center is different in diameter.

In and older trucks, the top pin has a larger diameter, and the green pin used on the and newer is thinner.
