When trying to use the reach or other functions that activate the auxiliary pump, it does not respond and I get these error messages:"AUX PUMP OFFLINE" or "DISPLAY CAN BUS FROM AUX PUMP" or "CAN DISABLED". The switches on the handle appear to be working fine and activating the valves. Also 36V is present at the auxiliary pump motor (B+ circuit). Everything else works very well in this truck. Can anyone help me troubleshoot this and find out what is causing the problem? Perhaps the auxiliary pump motor or the CAN I/O?
