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). Brakes still work fine but not as firm as usual after a flush.
I've looked around and it seems like older Subaru models can self cycle per this thread:

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.
