Brake Bleeding - How to Cycle ABS Valves?

Any anyone here figured out to cycle the ABS valves on our cars without a diagnostic tool? I know I can get a harder brake pedal feel but after boiling some fluids at the last track day and activating ABS a couple of times, I feel like air may have gotten into the ABS modules that I can't seem to get rid off after two bleeds (where no air came out on the last one).

I've looked around and it seems like older Subaru models can self cycle per this thread: https://www.iwsti.com/forums/gd-gene...-problems.html

I'm wondering if such a self diagnostic mode exist for our cars. Otherwise I need to buy an OBD tool that will do that for me, and who wants to spend extra money on a tool when you can do it for free! Thanks.
