You have probably figured out by now that your ABS is showing a fault. There are three places that can send this fault. Front, rear sensors and the ABS control unit.

I bought a R1100RS with a bad (damaged) front sensor. After replacing the front sensor the flashing continued. After trying to reset the system myself (jump some of the connectors with a short wire) I took the bike down to the BMW dealer who reset the ABS system for $50 and I was back in business.

Now the ABS just fails to reset when the tempratures are below 40 degrees. I let the machine warm up completely and the ABS will setup properly after I get moving at about 15 mph.

If you are convinced that the front and rear ABS sensors are in good shape and set the correct distance, It is your ABS central system. If you are lucky, it just needs to be reset. If you are not, the unit itself will set you back $400-650 depending on whether you get a used or a new unit.

Unless you are really good with electricals, you will probably end up at the BMW dealer to get this resolved.

If you want to try yourself, google the problem until you get one of the BMW rider pages, and you will find the steps to reset the ABS. Good luck and enjoy your R bike. I do enjoy mine....yes, mine is a red one also.

Clutch cable rubbed a hole in the rear brake line. ABS light still on after repair. How do I reset it?


The ABS light should stay on until you reach a speed of about 3 MPH or higher.

Did you check for error codes?

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted)
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.

9 - Press and release the odometer reset button to continue to the next module.

10 - Turn Ignition switch to OFF.

On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.

"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

Also if the code set is a historic code (not a constant light) after 50 start and run cycles of at least 30 seconds each in duration, the light will extinguish itself as long as the error hasn't occurred again.
If it were a current code, the light would remain lit while running.

If you clear the error code (step #8), the light SHOULD reset.

My 1995 K75 ABS system has failed. I have checked the sensor gaps and they are fine. What would be the next step.


Locate the blue ABS 3 pin connector underneath the side cover, attach a piece of wire to the MIDDLE pin and other end to good ground such as motor mount bolt. Turn on the ign switch, press front and rear brake levers to extinguish the red bulb checker light in middle of your instruments, ABS lights should start flashing indicating reset mode, now press the ABS reset rocker switch on the handlebar pad and hold for slow count or 10. Release , turn off ignition, remove wire and try it! I have reset units that the dealers said were bad using this method. It unlocks the Cmos chips in the module.

Abs light flashing alternatively when putting ignition on


There is a simple way to fix it as I've discovered. Start your bike, if lights are flashing ride for a mile or two applying the rear brake a few times. Stop the bike and place on centre stand. switch off motor then restart. Your flashing lights should have gone. Why the flashing happens is if you ride and use your rear brake rarely and then your bike sits for a day or two without use your rear brake assembly fully retracts, ie pads away from disc and ABS gizzmos inactive. The ABS sensor unit then reports extended non use pattern to the onboard 'brain' which activates the warning mode of flashing lights. This has worked for me several times over the last 5 years when its occured. Full ABS operations return. Tried it on a mates bike and it fixed same problem on his.
