Hey there does anybody know what these codes mean? I was running my machine today and it came to a sudden stop than flash these codes motor still ran fine just would not go forward or reverse. Let the tractor sit for about 15 minutes everything worked again lights on dash were normal then 3 to 5 minutes later stopped again. Any suggestions of where to look or start thank you
Welcome to HEF hrmatt ! Will need a machine serial number for accurate information. 91.09 should be the ECU is not receiving throttle signal from the TCU. 609.09 would be no "CAN" communication from the TCU to the monitor. Intermittent power or ground for the TCU could cause this. Wiring issues with the CAN network. Mouse damage? Cab mounts wore out? I have seen them wear out and crush the wiring harness under the floor board area. Inspect the wiring harness thoroughly from the TCU all the way to wherever it goes for damage, pinch points, etc. What I don't like is that restarting gets you going. Either the TCU shuts down because it sees something it does not like, or the TCU is turning sour. Key on. Press and hold the menu button until in the service mode (about 5 seconds). Scroll to codes. Press select. Scroll to clear, press select to clear the codes. Cycle key. Let's see what codes return, if any, when the issue occurs.
