| The SDB is designed upon a standard SAE serial communication protocol callded "J1850". The digital data is transmitted and received on a single wire at around 10.4 Kbps. This protocol was used thru the 2013 model year. | The SDB is designed upon a standard SAE serial communication protocol callded "J1850".
