That's exactly what happened when my 10SG abs failed, hard lever on front brakes on mine. It's been a few years now but it cost me about $600 to fix the modulator.
The sad part is that it was replaced with the same HCU, it could happen again. Six hundred bucks seems like a bargain when you're headed straight thru a curve and get a hard pedal or lever. They didn't let you keep the old HCU even though you paid, huh?
When mine fails, I'll strip out all the ABS plumbing and install non ABS lines. Then I'll put a piece of black tape over the light It'll save me some money on ABS wheel bearings as well.

Unless the bike is a Road King Special ABS is/was an expensive option. My 2012 RG Special was the first Harley I had with ABS, then my 15 RG Special was the first with linked ABS. I am absolutely certain you need the fluid changed every two years, and you need the dealer to do it. I may have been wrong before, but since I am a Marine, I seriously F'n doubt it.
ABS (and security) were standard on the Road King Classic.
I've been schooled ... Years of mechanical experience and I'm still picking up "lessons"

You didn't know because no one with your experience would ever dream someone would manufacture a system like that.

I thought that in order to bleed HD ABS brakes, you need the official "Digital Technician II" device from the MoCo, and they only sell it to authorized dealers.
There is another tool that will do it, I can't think of the name off the top of my head. It's pricey. I just got back from strafing the local roads on my 2002 FXD-X. Great suspension, no ABS and a carb that makes the throttle smooth as silk thru the curves. A motor, two wheels, place to sit and a pair of handlebars. I've bought my last new HD.

I stand corrected here. Went over to the indy shop next door and asked about this issue. He said they have what they need to service all HD's through 2017. The system they have wasn't sold to them by the MoCo. Some day when I have more time, I'll see if I can learn more details.
But that aside, I'm with you. I don't like this stuff where a guy can't maintain his own motorcycle.

ABS on motorcycles was first developed by BMW in 1985, it can be a life saver but must be maintained properly. Not saying it wasn't OP, but you're in the best position to speak on that. It does need not only a brake fluid reservoir flush, but in most systems the ABS "module" needs to be flushed as well. Two years is the outside limit. Generally it does have to be done with a manufactures system. In the case of BMW they are owned by BMW corporate and leased to dealers. The HD dealers may own them, or lease them, don't know. So I have to reserve judgement as to fault on this failure. Could be HD, could be a dealer screw up, or could be pilot error in maintenance. If it's gone 5 yrs without proper maintenance ........?
If he does his own maintenance, then he needs to do ALL of the maintenance. You can't just do some things and let other things go.
If he isn't competent to do maintenance, he needs to bite the bullet and take the bike to the Dealer to have the maintenance done properly.
The more I learn about MoCo ABS, the more I conclude that doing your own maintenance on it is a practical impossibility. You have no choice but to take it to a place that has invested in the required computer.
