Description: True
The previous attempted shift to High gear failed
False
The previous attempted shift to High gear was successful
Note 1: The Upshift Failed flag is True as long as the Air Pressure Out Of Range Flag is True. This
will NOT set or reset the failed shift flags. However, once the Air Pressure is within
desired limits the failed shift flag will disappear when the Air Pressure Out Of Range flag
is False.
Note 2: The Upshift Failed logic will go True for 1 sec when there is unsuccessful upshift fail flag
for Neutral to Low or Neutral to High.
Note 3: The Upshift Failed flag will be set to True if the transmission sets both the unsuccessful
upshift fail Neutral to Low and Neutral to High flags to True. This flag can only reset on
Power Cycle.
Note 4: The system will hold the current gear once it has encountered an upshift fail (Limp Home
Mode) irrespective of the commanded transmission mode.
