My 2018 T100 Bonneville was due for the biannual brake fluid flush, and my dealer is four hours away. I had heard of the "DealerTool," which can open the valves in the antiskid system, so I ordered one (www.dealertool.com) from the English provider. The OBDII adapter arrived in good order, so I downloaded the DealerTool files from their website into my PC and opened the program. One minor inconvenience is that the purchaser must return a code from the program to the folks at DealerTool, and they send back a key which is loaded into the program. However I received the code from DealerTool in less than a day. I also made covers with a 1/4" NPT pipe fitting attached so that I could use my pressure bleeder (Motive Products Power Bleeder www.motiveproducts.com) rather than having to pump the brake levers. The DealerTool worked as the directions showed, and the antiskid pump could be heard when the bleed button was selected. I selected the bleed button several times to be sure all of the fluid was flushed from the master cylinder, antiskid system and brake calipers. It was also interesting to go through all the tests and diagnostics that can be done and read with the DealerTool.
In short, I would highly recommend the DealerTool if you do your own maintenance.
