Data Display Menu

Description:





In this mode of operation, the scan tool allows the technician to command the Body Function Controller (BFC) to display its various inputs, outputs, and Instrument Cluster information for ease in diagnosis. This mode can be used to determine whether the Body Function Controller (BFC) is receiving data correctly from the Body Function Controller (BFC) inputs, the Instrument Cluster or the Powertrain Control Module (PCM) and if the computer systems are operating properly. The choice of inputs that can be read are listed in TABLE #3.
