You can't use the 100 series bleed procedure on the 200 series. You've really messed up. New AHC system about $50K
Just kidding!
My understanding system has a fail-safe for low fluid/pressure. Pump has shut down. Go into tech stream and use the test mode, active/test the pump. May need to do...
AHC fluid is just hydraulic oil, oil doesn't evaporate. So no!
But we can weep a little at shocks (which is ok, if not dripping off shock) and loose some that way. Any other leak would needs repairing IMHO.
