High Speed Controller Area Network 1, 2, 3 and 4 (HS-CAN1, HS-CAN2, HS-CAN3 and HS-CAN4)

WARNING: This page is about a different car, the 2024 Ford Maverick. However, it is still accessible from the selected car via links, so may be relevant.

The High Speed-Controller Area Networks (HS-CANs) operate at a maximum data transfer speed of 500 Kbps and are designed for real-time powertrain, audio, multimedia and driver feature information transfer and control. Modules on the HS-CANs communicate using bussed messages and use unshielded twisted pair cable, data bus (+) and data bus (-) circuits which allows sharing of information between all modules on each network.

The GWM transfers messages between the diagnostic scan tool and the modules on the HS-CANs.

The GWM translates the diagnostic messages from the DIAG1 network to the HS-CAN1 allowing communication between the modules and the diagnostic scan tool.

The GWM translates the diagnostic messages from the DIAG2 network to the HS-CAN2, HS-CAN3 and HS-CAN4 allowing communication between the modules and the diagnostic scan tool.
