John Deere 1499: Separator Engage Output Transistor Fault

The separator engage output transistor has detected an open, short, over voltage, or over temperature condition. The Armrest Control Unit has disengaged the separator as a result. The fault condition must be resolved before the separator can be re-engaged.
