Does ABS light mean the ABS is not working?

I realize that the ABS light can come on for various reasons and means the system needs attention. But, does it also mean the ABS are none functional or that they simply need attention before they become none functional?

usually it means it's not working,, i just had this problem, my light was coming on too,and it was not working, as did another member here,,
what we did was start by taking out the back sensor on the rear differential and cleaning and making sure the wires were connected well, as well as the same thing with the front connections,, mine ended up being the back , the wires were coated with alot of ice and snow,, thus putting pressure on the connection , after i cleaned all the crap off it and put it back in, it woks , and no more light,,
there is ways to test the sensor , i am not sure , one of the techs on here might chime in and tell you the test procedure,
check the connectiond first , it might be that easy .

check the connections of the speed sensors (both on the rear differential and on the front hubs) also check the relays under the hood that operate the abs system. i think there may also be a fuse.

Light = ABS disabled. Like the other guys here said, it is likely to be a sensor that has an issue. If you want to know for sure you need a special scanner to read codes.

Ditto. The only way to know for sure what the issue is would be with a scanner capable of reading ABS codes (and they're not cheap). That being said, replacing the rear axle speed sensor seems to fix the problem roughly 3/4 of the time around these parts.

Can't hurt to try... worst case, you're only out another $15 bucks on top of the real problem.
