What happens when coolant temp is too low?
Set conditions: The PCM detects that the actual coolant temperature falls too far below the predicted engine coolant temperature and the predicted engine coolant temperature reaches the predicted target value before the actual coolant temperature reached the actual coolant temperature target value.
