Data Display

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