Hi, i need some help with my 2012 L230 skidsteer. Symptoms: error code 4431 After about 70 hrs on the hr meter the display would sometimes beep after morning startup as soon as the operate button was pushed. A yellow dash light that looks like an upside down capital letter T. It would beep and display that light just after button was pushed and i could feel the park brake releasing. The light would stay on for a second or two then go out and i would use machine as normal. The beep and light has become more frequent after startup which is telling me something funny is going on as it never done it when i bought the machine with 16 hrs on it. Today, i was turning a windrow and the park brake light started flickering on and the upside down T light also cane on along with a beep but the machine still was driving fine. I turned it off and re started it but as soon as i press operate button the park light stays on along with the upside down T. If i press the park button the park light stays on but wheels wont drive. If i press operate again it will move off but park light remains on aling with fault code 4431 and the upside down T light staying on. Ive tilted cab and waiting on your instructions. Thanks
