Scan Tool Data Display

The Scan Tool displays the module data. This information assists in determining whether the module is operating properly and whether the module is sending or receiving the proper data to and from a particular system. The module uses data received from other systems in order to carry out some functions. Therefore, if the module receives the incorrect data from another system, the module may function improperly. Use the Scan Tool to review the data from the systems that interact with the module.
