When cold and you put it in gear it does circles to the left track side in forwards or reverse. Plus if you run it over 3/4 throttle it will die and not restart until you idle down and it will run all day at 3/4 no problem no codes. Ideas?
Welcome to HEF Havoc ! Serial number? Any codes? Press and hold the menu button until monitor beeps and Service Mode appears in the screen. Then scroll to codes and press select. Then scroll to active, press select and record the codes. Then do the same for stored codes. Then scroll to clear codes and press select to clear. Run machine and see what codes return. Post all codes listed, active and stored and the codes that came back.
Thank you serial number is TO650JX153367 I be back at this machine maybe this afternoon but for sure tomorrow I got a few other things to do at a different location
theses are stored codes Sdm 107.4 Ecu 1569.31 Ecu 1076.13 Sdm 3359.31 Sdm 2000.9 Sdm 609.9 Ecu 110.0 Sdm 177.16 Sdm 107.4 Active 107.4
This is an air filter restricted code. Might be related to our engine issue. Does the engine want to blow black smoke when at fast idle? Has the air filter been changed? For this I would check your fuel tank vent and your your fuel supply system from the tank to the injection pump. Sorry, forgot to tell you how to get the transmission codes. Left rear corner inside the cab is the TCU. Remove the cover. Key on. Press menu until code is displayed. Press select. Record the code and press next and record each code until the word END appears. To clear the codes: with the word END in the window press and hold select until F300 appears in the window. That means the codes are cleared. Turn your key off. Restart and run the machine and record what code comes back. Post results.
I check the air filter after I got code it was full of soot from muffler being broke right at the top so I blow it out for now and order a muffler and air filters I will check the tcu today’s. Thank you so much for your help
Let the operator run it today after clearing the code on ecu side it had on was 107.4,1076.13 then 1569.31 but for the tcu f382,f301,f383,f373,f393 code that came back after clearing is f383
F383 is an issue with the right track speed sensor or it's wiring. If it is wiring you can repair it and run. If it is a sensor then the transmission has to be calibrated after the repair. You may be asking why the right speed sensor when it mistracks to the left? The "auto tracking" feature of the software in the TCU always tries to slow the fast track, so if the right speed sensor fails the TCU sees that the right side is slow so it tries to slow the left track to match it. Hence the mistrack to the left.
Thank you for your help
