Driver Door Ajar Switch - Range Yes/No

The Body Function Controller (BFC) uses this input in determining whether the Driver's Door is opened or closed. The input is received by the Body Function Controller (BFC) and is used to wake-up the Body Function Controller (BFC) from a low power mode and must be detected when ignition power is inactive (off). The Body Function Controller (BFC) also sends the information out on the Serial Peripheral Interface (SPI) to the Instrument Cluster to light the Door Ajar Symbol Indicator. On, is displayed when the door is open. Off, is displayed when the door is closed.
