The implement control system has a built-in feature that monitors the position of the control levers. This feature is operable when the key is in the ON position, and ensures that the lever mechanisim has returned the lever to the center position. The levers should not be moved with the engine OFF. If the operator moves the lever out of the center position, with the key switch ON and the engine OFF, a service code will be logged. The three possible service codes are listed in the chart. If it is determined that the service code is being logged due to an actual sensor problem, see the references listed above.
