Pressure sensors
ECS Gen. 2 systems have four pressure sensors (five if
front air suspension is fitted):
B24 - lift axle lifting bellows
B55 - lift axle suspension bellows
B56 - front axle bellows
B57 - drive axle bellows RH
B58 - drive axle bellows LH
This allows the pressure in each individual circuit to be
separately monitored.
This means that the pressure control valve is not needed,
