Principles of Operation: Notes

The vehicle has 2 module communications networks:

• High speed controller area network (CAN)
• Medium speed CAN

The diagnostic tool connects to the communications networks through the data link connector (DLC). The DLC allows a diagnostic tool access to diagnose and test the vehicle systems of any module on the communications networks.

Both communications networks are connected to the DLC. This makes diagnosis and testing of these systems easier by allowing one diagnostic tool to be able to diagnose and control any module on either communications networks from one common connector. The DLC can be found under the instrument panel between the steering column and the driver door.
