| Was system working and this suddenly happened? Any recent service work done to tractor or software update? I would get dealer to come look at it if available. Machine may need to be recalibrated. With dealer EDT tool, dealer should be able to see if the PVED valve is turned on as well as doing a wheel angle sensor test. Vehicle profile should be loaded when tractors initial steering calibration was done. Vehicle profile measurements can be manually put it or dealer or whoever has the EDT tool can load proper profile. | |
