Hello, my name is ***** ***** I will help you with this. Let me ask if the machine is running and this happens, or is it when you turn the key on you get this code? Normally on these machines this is an indication of ecu failure, check fuses for the ecu #15, #17, #18. If they are good, remove the I-ecu and tell me if the number on the white sticker on the back has a 4402 at the end. The most common ecu to fail is the I=ecu and almost all machine will need to have that replaced. What are other symptoms, does it shut off on occasion, engine surge, lights flashing in dash, shifting errors. Those will all indicate different ideas just let me know.
