Until we have an option to electrically cycle the ABS Module we cannot complete the flush at home. The procedure is to flush the system to get fresh brake fluid in the system (not difficult), then cycle the ABS Module, then flush the brake fluid again, then turn off the service light (wrench). Hopefully one of the aftermarket OBD makers will have a system to cycle the module soon.

Walk in the park, but keep in mind that will need to buy a scan type tool to cycle the ABS pump for the bleed in the first place.
So on that note, the abs cycle tool average around $300, but if you are power flushing the fluid every two years as you should, will pay for it self over dealer charges to do the service instead.
Down and dirty, empty the reservoirs to get that older fluid out of them, do your basic pedal/lever pull flush to get most of the old fluid out of the lines via the bleeders, then do the power cycle flush to draw new fluid in/push the old fluid out, the do another bleeder flush again to get the last of old fluid out.
If you don't have the tool, then there is a work around, hence do the first bleed, the go find a dirt section to get into the brakes hard enough to kick the ABS system in to play so it driving the old fluid out/new fluid back into it to pump (leave rear abs on), then come back and do a final brake bleed.
And the one that kills me, bikes with the infotainement systems, should already have a menu in it, to be able to cycle the abs system for a brake bleed. The pan American is sold at an adventure bike, where 99% of the time you need to be able to fix something on the fly out in the middle of no mans land, and if say you have a loose brake line that you need to fix and add more brake fluid, no being able to cycle the ABS pump to get air out of it, could leave you for days until you can get into a country that does have a HD dealer to cycle the pump to get the air out of it.
Hell, better, why in the hell does an adventure bike have an abs system in the first place, since the first thing you do off road, is turn it off (if possible and not just rear alone).
Fact is, BMW may have started the adventure bikes with the GS models, but the die hard off roader's, ABS pump gets ripped out, leaving only the controller behind since it controls the brake lights.

The wrench light would still be on nonetheless. We need a tool for that.
