SCV control lever communicates its position to the ACU. This information is sent to the SCC through tractor CAN bus. It is then converted and sent to appropriate SV control unit through SCC/SV CAN Bus. SCV control lever will provide a means of controlling SVs in a number of different ways, depending on operation mode or position of lever.
Communication between selective control valve CAN control unit (SCC) and selective control valve units (SV1—7) and is done on a dedicated CAN network. This CAN network allows for commands from SCC to be sent to each individual SV control unit. SV control units reply to SCC with their respective positions and flow rates. Codes will be set if communication to or from any of these control units does not happen.
