Hi Beam Lamp - Range on/Off

This data indicates what message is being sent from the Body Function Controller (BFC) to the Instrument Cluster to control the High Beam indicator illumination. On, is displayed when the Body Function Controller (BFC) is commanding the High Beam indicator illuminated indicating the High Beam Headlamps are illuminated. Off, is displayed when the Body Function Controller (BFC) is commanding the High Beam indicator not to be illuminated indicating the High Beam Headlamps are not illuminated. The Body Function Controller (BFC) reads the high beam input voltage and divides by the system voltage to determine a percentage value. This value is compared against a calibration to determine if the High Beams are on. It forwards this status determination information to the Instrument Cluster via the Serial Peripheral Interface (SPI) data line. The Instrument Cluster commands the hi beam lamp accordingly.
