i have a 560-opc30tt. the steering hunts rapidly back and forth within about an inch or so.it has no codes, the steering has very little end play. the steer encoder seems to be ok as i can turn the steering slow it does not studder or jump at all. the problem seems to speed up or stop after a few seconds, im shotting in the dark and thinking the steer encoder in the steer motor is bad.
any other posibilities?

thanks
