"Extended brake control" function module

4.4.1 Features
The extended brake control function has the following features:
S Forced brake release (p0855, p1215)
S Close the brake for a 1 signal "unconditionally close holding brake" (p0858)
S Binector inputs for releasing/applying the brake (p1218, p1219)
