High Speed Controller Area Network 3 and 4 (HS-CAN3, HS-CAN4)

WARNING: This page is about a different car, the 2020 Lincoln Aviator. However, it is still accessible from the selected car via links, so may be relevant.

The HS-CAN3 and HS-CAN4 operate at a maximum data transfer speed of 500 Kbps and are designed for real time audio, multimedia and driver information transfer and control. Modules on the HS-CAN3 and HS-CAN4 communicate using bussed messages. HS-CAN3 and HS-CAN4 use an unshielded twisted pair cable, data bus (+) and data bus (-) circuits, and allows sharing of information between all modules on the network.

The GWM is used as a gateway for the messages to transfer between the scan tool and the modules on the HS-CAN3 and HS-CAN4.

The GWM translates the diagnostic messages from the DIAG 2 to the HS-CAN3 and HS-CAN4 and vice versa, allowing communication between the modules on the HS-CAN3 and HS-CAN4 and the scan tool.
