Body Main Menu

The scan tool software is broken into major computer controller groups that are found in the body of the vehicle.

The Body Function Controller (BFC), in addition to being an element of the Class 2 serial data link, also has hardwired inputs as do the Powertrain Control Module (PCM), Electronic Brake Control Module (EBCM), the Instrument Cluster, and the Sensing and Diagnostic Module (SDM).

Some of these inputs are used to display information for the Instrument Cluster gauges and indicators while other inputs are converted into serial data link and transmitted on the Class 2 serial data link and the Serial Peripheral Interface (SPI) serial data link.

The Body Function Controller (BFC) is the only interface to the Instrument Cluster, the Body Function Controller (BFC) converts Class 2 data to Serial Peripheral Interface (SPI) for the Instrument Cluster. The choice of inputs that can be read are listed in TABLE #1.
