1299S 2016 ABS Problem ABS light randomly On

Hello, Guys I need your help.
For about two months now i'm randomly getting the ABS light sometimes after only a few meters sometimes after a few kilometers, but every time after a while it does come on. I haven't had a trip without experiencing the ABS light to come on since.
Now the bike has 2500 km, and the problem occurred at about 2000 km.
In the little distance i mange to ride the bike without the ABS fault and I tested the ABS by locking the rear brake and it does engage and it works as it should.
I have a TEXA diagnostic eq. and I've got a dct code "C1015 ABS pump motor"
With the error on, I've consulted the parameters and couldn't find anything wrong, the wheels speed sensor they seem to read the same.
The resistance between the front and rear one seems to be roughly the same, about 463 KOhms.
The only thing I've noticed was "Cornering strategy not working due to IMU sensor fault".
I've replaced the IMU sensor and reset the factory position and nothing changed.
I couldn't find time to take it to a dealer this summer because the nearest one is about 500 km away.

Do you guys have any idea what could it be wrong with it?

Problem solved!

After I replaced the IMU sensor and front wheel speed sensor with no effect, I finally decided tot trust my TEXA diagnosis which gave me the error C1015 ABS pump motor, das today I made the decision to chech the abs unit more specially the motor on the unit. Motor's magnet cap/shield is hold to the unit with two E6 bolts not that hard to remove tham with the right tools. When I removed the cap i've noticed some light black dust on the rotor and in the cap.
I measured the resistance between the brushes and gave some 6-9 Ohms.
I washed the whole inside parts (rotor and brushes) with brake cleaner, spined the rotor to wash the brushes gave it some more brake clean, checked the brushes to see if they contact now properly and mounted everything back.
I took the bike for a long test drive, And no more ABS light while riding. Problem solved!

I forgot to mention that after I cleaned everything the resistance between the brushes dropped to 0,8 ~ 1 Ohm.
 
Hi,I have same problem with C1015.But I observed that ABS error light appear when driver a moment(10-20KM) and engine temperature rised,then restart the motor,there were most probability appear again,Unless return cold.
