Park Brake Switch - Range Yes/No

The Body Function Controller (BFC) uses this input in determining whether the Parking Brake is engaged. The input is received by the Body Function Controller (BFC) and is sent out on the Serial Peripheral Interface (SPI) to the Instrument Cluster to light the Brake Indicator. The Body Function Controller (BFC) also sends the information out on the Class 2 serial data line for use by other modules. Yes, is displayed when the Parking Brake is engaged. Off, is displayed when the Parking Brake is not engaged.
