The software communicates with the vehicle's electronic systems primarily through the SAE J1939 and J1708 datalink protocols, which are standard on most modern commercial vehicles. For critical operations such as reflashing (programming) a transmission ECU, Eaton mandates a direct, hardwired USB connection between the computer, the adapter, and the vehicle. The use of wireless connections like Bluetooth or Wi-Fi is strictly prohibited during programming, as a dropped connection can corrupt the ECU and void the warranty.
