I make such a tool (sorry for the repetition, just want people to be aware we have an affordable and very easy to use tool now for the DIY crowd). Link is in my signature!
Don't take chances with the brakes, take it to the dealer. Save money on something else, not your safety. As someone said, "if the brakes don't stop you, something else will".
There is another system available that does much more than the HD2 tool but it's also a lot more expensive. Daytona Twin-Tec 4.
My custom version ("Shop" version) actually does more than their tool and is cheaper. Most people who bought the old Daytona tool only need/needed the ABS function hence one of the reasons I decided to create a low cost single purpose tool.

While I agree on principal (i.e. maintain your braking system) I don't think most do so adequately if for nothing else it's pricey at the dealership (and time consuming to travel/wait/etc).
Our tool performs the exact same procedure as the dealer tool and gives you the freedom to perform the procedure in your own garage. In addition, after the second flush with our tool you are already money ahead. Peace of mind and job well done satisfaction. Win!
I bled the front brakes on my 2014 softball with abs after bar install by cracking bleeder and letting it sit overnight.
Worked for me but maybe I got lucky.
Did you let the reservoir run dry or replace a brake line (i.e. a longer line due to higher bars/etc)? If not then yes as long as air isn't introduced into the HCU then you would be "OK". However, when you flush your brake fluid (every 2 years minimum) you won't be able to evacuate the trapped fluid inside the HCU without the dealer tool.
I’ve got a 2012 softail slim,3 days ago I decided to swap out my original bars and handgrips and levers. I added a longer brake line up front that goes from the MC to the ABS. How would I know if I still had air in the line after bleeding? I used a vacuum bleeder that pulled out a ton of air and then I stopped when I was getting fluid only but the thing that was weird is the only way I got the fluid to flow was by squeezing the brake lever. I had the bleeder open and the vacuum pump at about 25 and nothing would come out until I squeezed the lever….
