jlg 40e "procedure fault"

    hope the Jlg experts out there can help me with this one. JLG 40e worked great until last fall when it just stopped responding. Flash code on controller was one flash, internal fault. Controller replaced, batteries replaced, but unit still will not go fwd/reverse or move boom, (except that all boom controls DO work if function selected and then steer switch applied.) I guess this verifies that the pump and hydraulics are good, but something wrong with controls. I note that the controller flashes 2-flashes when the foot switch is pressed, even if no control input is selected. Strange. Steering function OK, drive motors- nothing.

    I have multimeters and am pretty good at troubleshooting but I can't figure this out. Any ideas?

    Thank You!!!

    I didn't find the right solution from the Internet.
