Information Bus: Component Tests and General Diagnostics
Circuit Operation - UART Data Line
The data line is the communication link between the various modules in the vehicle and the technician. Besides allowing the modules to communicate
with each other it allows the technician to run system diagnostics via the Data Link Connector (DLC). This allows the technician to read and erase
diagnostic trouble codes using a scan tool (among other functions).
