High Speed Controller Area Network 1 and 2 (HS-CAN1, HS-CAN2)

WARNING: This page is about a different car, the 2019 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The HS-CAN1 and HS-CAN2 operate at a maximum data transfer speed of 500 Kbps and are designed for real-time powertrain and driver feature information transfer and control. Modules on the HS-CAN1 and HS-CAN2 communicate using bussed messages. The HS-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, the HS-CAN allows sharing of information between all modules on each HS-CAN.

With the addition of more modules, network traffic has increased. This has created the need for an additional HS-CAN to manage the increased bus data carried on each network.

The GWM translates the diagnostic messages from the DIAG 1 network to the HS-CAN1 and vice versa, allowing communication between the modules on the HS-CAN1 and diagnostic scan tool. The GWM translates the diagnostic messages from the DIAG 2 network to the HS-CAN2 and vice versa, allowing communication between the modules on the HS-CAN2 and diagnostic scan tool.
