Hi Jon G,
My listing says this is an EASI-R30TT
S.No ES-09-16873
I have come to the conclusion this may be a system failure possibly a specific card or module that handles the auxilaries such as reach tilt and side shift,
Not being familiar with this make of truck Ive been on a steep learning curve, and i have proved to my satisfaction that the hydraulic components are ok having substituting tthem on to a known good truck. the only thing i have not had my mits into is the electronics, but I think I will have to try swopping a few boards around,
