ABS Sensors - W140 Chassis

My ABS light goes on when I make a hard
turn at low speeds. When I restart the
engine, the ABS light goes out. Do I
have to replace the sensors or is there
some kind of cleaning, etc. that can be
done for a fix? Is there something that
I can do to prevent this from happening
again? The car is a 1993 300SD with
117K miles on it.
I saw on the NHTSA site a service bulletin:

SB032522
1993 MB Service Bulletin Number: MESS#84
ABS activates or warning lamp lights when
braking at speeds below 10 MPH.

Do you have any details on this?

Thanks
