code 80 is throttle control out of range
code 81 is lift control out of range
providing all your cables are connected properly and secure in their sockets and no damage to any cables, you need to go into the TM and relearn the controls.
What did you do since our previous posts?
something you may have inadvertently done could be causing this new set of codes. The fact that you are getting simultaneous codes from the control handle for lift and travel is unusual. did you replace the eeprom and/or board in the TM? Disconnect anything while checking the unit and maybe connected back incorrectly or may have damaged some wiring?
