Actually many Dealership will say don't flush it, you'll damage the system. They may very well say "sorry you messed up". How fat is your wallet $$$, before we replace the AHC system for you. This issue of not running when drained of fluid, IMHO is why many shops say we don't flush the 200 AHC.
But Dealership/shops that say this, are wrong IMO.
Think about it!
Would Toyota engineers design a system that one leak, say in reservoir, which set near ground behind a tire with lines running around undercarriage exposed too road hazards. Allow fluid loss to destroy the system. IDT.SO
That is not what I'd call a third world ready system or off road reliable.
Just letting setting with fluid in reservoir will help, as fluid will settle in. The pump can burn up (my guess) if run dry. So system is refusing to run as a safety. A few start in stop with tech stream and it will work. No Tech stream cable, just start and shut down (key on start, then off and wait) should do the trick. May even need to disconnect battery (reset system DTC) if no results, but it will work.
