Buddies 07 R12R here with ABS light blinking. Battery tests fine
GS-911 shows code 24048 and 24049- Power supply to pump motor faulty
I guess this is a stuck brush issue as well?
Has anyone had any luck with a few mild taps to the motor to see if the brushes "unstick"?
I tried the "hammer tap" tonight and it did get the pump motor working again. I certainly will not count on this as a long term fix. Don, do you have a link on how to get the motor off and apart? The only video I found was a complete hack job!
Doubtful. The failure here is of the brushes, as they wear they move in the holder and start to bind. The only way they will wear is if they are being used at times. It's fairly easy to trigger the ABS on the Series-II system by using the rear brake as you would on an unlinked bike, you're almost certain to over-brake the rear, causing a buzz in the pedal - which is the ABS activating. I almost never use the pedal except for low speed cornering - or holding the bike on a hill. The linking is much better at proportioning the forces then I am.One thing I recall hearing about the ABS modulator on the pre-07 whizzy-brakes BMWs is if the ABS system is never activated, actually put into full cycle operation, that failure issues can occur internally. I wonder if there is a correlation here with the current revision of the ABS systems on the R-bikes.
Even if it has no good effect on this problem - that's still good advice. A rider may well be surprised at how quickly one of the ABS equipped bikes really can stop in an emergency and tend to let off the brake unless they are used to how the ABS feels when it kicks in.As a long time MSF instructor, one big thing I teach/preach/emphasize is regular high-effort braking practice. Mostly for the experience of knowing what you (mostly) and your bike are capable of doing. But also to get familiar with high effort braking. With that, if your bike is ABS equipped I strongly advocate actually practicing braking stops that get the ABS system fully active. Keep in mind, that until an ABS system senses actual pending wheel lockup (skid) it does NOTHING but monitor wheel speeds relative to vehicle speed.
If say, in 50,000 miles of riding you never fully activate the ABS system, certain components internal to the system never become active more than the initial start up cycle test. But that does not fully activate the system like an ABS activated stop from 60 mph. On my 94 R1100RS, I regularly practice high effort brake stops and I get the ABS systems activated also. Even though my bike is approaching 20 years of age, the ABS system still works great.
Interesting comment. I too love my bike and RT's in particular. But with all the truthfulness ever assembled by man BMW NA is the worst OEM I have EVER had to deal with in 30 years. Their arrogance is simply amazing. Even had one of their rep's lie (yes, I do mean lie) to my face once and I called him on it. His response? "I don't give a sh** what you think." Never ever had a rep respond in such a manner. Over the course of time I was pretty much merciless with them as I sincerely wish all BMW dealers need to be but won't. Nothing seems to work with them. Neither kindness nor rudeness or the facts seem to alter their own little reality. NA really needs to be taken down a peg or two but most folks within the dealer network are in fear of doing so. If only every BMW dealer in the USA would rise up against them and fight against such crap. Gee, do I sound mad?
I don't know BMW's method of indoctrination when it comes to their employees but they fall into BMW corporate-speak and that's the end of it.
The sad part is I still love RT's and much of the BMW product in general. Doesn't say much for my intelligence as I still give BMW money for some of the products they make.
