Brake Control Module

Each BCM mainly consists of a hydraulic manifold that installs a Shut Off valve (SOV) and two Electrohydraulic
Servo Valves. These latter ones allow the control of the braking pressure on each brake and
are installed downstream the SOV.
Each Servo Valve is connected and can be controlled by the corresponding BCU:
– Servo Valves Normal Right (SVNR) and Left (SVNL) by BCU Normal,
– Servo Valves Alternate Right (SVAR) and Left (SVAL) by BCU Alternate.
The BCM is also equipped with:
– A pressure Switch on SOV output line, to detect SOV activation: SOVN on normal channel and
SOVA on alternate. Actually, the Pressure Switch function is implemented by a Pressure
– A Pressure Transducer downstream each Servo Valves to close the control loop on WBA for left
and right caliper: PTNR and PTNL for Normal channel and PTAR and PTAL for Alternate channel.
