Ketoacidosis occurs as a response to too little insulin. Since Type 2s still produce insulin, it doesn't usually occur.
Wikipedia lists the causes of this dangerous condition for Type 1's :
intercurrent illness (pneumonia, influenza, gastroenteritis, a urinary tract infection), pregnancy, inadequate insulin administration (e.g. defective insulin pen device), myocardial infarction (heart attack), stroke or the use of cocaine. Young patients with recurrent episodes of DKA may have an underlying eating disorder, or may be using insufficient insulin for fear that it will cause weight gain
Ketoacidosis causes the formation of ACIDIC ketone bodies. These are different from the ketones produced during ketosis, as happens on a very low carb diet, when the body uses fat for fuel.
The key to understanding the difference between the two is that only one is to do with too little insulin.
Since you're a Type 2, there's little danger of you developing ketoacidosis
