ABS Warning Light On and/or Erratic ABS Operation on GMC Yukon

ABS system constantly active when brakes applied. Sensors were corroded from winter salt etc. I just pulled the fuse out and killed the system. They are a joke anyways and not required for inspections. A real bad design flaw that costs a fortune to get fixed. Not worth the money. Same yourself a lot of trouble and just pull the 15A fuse in the fuse box. I have driven for over 40 years without ABS just fine and don't miss them one bit. Just more Detroit planned obsolescence to get into your wallet.

Abs brake system light comes on at times. Brake shoes and fluid levels are good. Light goes off when car is turned off and usually does not come on when started back. It might come back on just driving down the road and not using brakes usually.

My ABS light would come on and go off intermittently. Dealer could never find a "Code" associated with this. Turns out it was the impending failure of the front wheel bearing. About a year later, it started happening again, the other front wheel bearing was beginning to fail.

ABS and red brake light came on indicating failure of ABS system, and there are no replacement ABS modules to be found.
One day my Traction light came on and prevented me form driving and code U0121 came which indicated loss of commonication with ABS system.
