I could be wrong here ,but To me it sounds like it might be The Panda-Door-a Box precursor to the next step of using the malady as the reason to remove Toyota Auto Scan feature entirely ( cannot be retained in future because an OE copyrighted sequence cannot be got around using unique coding)just like the Autel software for GM no longer offers autoscan feature (as far as I know) I just wouldn't do auto scan for Toyota and Lexus if you run the risk of corrupting what still remains working for you.
