hi folks.. my name is steve and i have a 2016 gmc sierra 3500. yesterday my message board came up service stabilitrac. the stabilitrac is not turning off though.. the light is on in the dash and i notice that the brake light is on as well. any help would be awesome. thank you in advance. brakes seem to be ok although the rear ones are starting to squeak a little.the only code i get on my reader is b0100 .
