Bullet-List
Operation of B022 - sensor, kickout
●
B022 - sensor passes signal to A004 - ECU (load-sensing pressure > 175 +/- 5 bar).
●
A004 - ECU transmits CAN message to A002 - ECU via K-bus.
●
A002 - ECU transmits CAN message to Y015-Y019 - valves via G-bus.
●
All preselected Y015-Y019 - valves move to neutral position.
