Pulling the ABS fuse will disable the ABS function, reverting back to the base system.
A missing tone ring will defaul to the base system, a bad speed sensor will also default to the base system.
Now a speed sensor that intermittently drops a signal or causes signal clarity deviation ....thats a different story.
i have had GM products that activate the ABS at a low speed stop say of 6-7 miles an hour making it difficult to stop on time. I almost drove through a few fences with those. Sometimes a loose/worn wheel bearing can create enough wobble in the signal that is causes an issue like that, also lots of brake grindings, pad material...ferrous buildup .... can skew the square wave generated at the WSS and ske the signal enough to activate the ABS to dump or apply pressure in an undesireable way.
Nothing live driving through the back of the garage or how about the transport guy who loads one on the top deck, just to find out the ABS wont let him stop.....:e vil:
