[QUOTE="jp84x, post: 125671, member: 23064"] Hi, I'm having a few issues with my bobcat. Everything mechanically seems to be fine, just throwing a variety of codes listed below. Typically it just beeps at me and otherwise keeps on working. The aux hydraulic is frustrating though as it will stop functioning - given that it is electronic I figure it's just the ecu locking it out? Sometimes I'll get all these if I go over a bump. Most of the time I can shut it down, immediate restart and everything goes back to normal. On the aux hydraulic I seem to be able to get it working if I leave the machine off for 30-45 min. It's a 2018 T770, 3050 hours, serial AT6315767 H7604 "unknown failure" M4404 "aux no communication" H4016 "right joystick no communication" H3916 "left joystick no communication" H7404 "main controller no communication" H7504 "drive no communication" M3204 "ACS (AHC) no communication to bobcat controller" Any ideas? Thanks in advance! John [/QUOTE]
