AWD Disable light came on as well as Anti-lock brake light

SOURCE: 2002 Buick Century anti-lock brake problems

i recently had this problem too, except i had all the lights on (ABS, service vehicle, trac-off, AND service engine) they are all easy to fix without spending more than 20-30$ for labour (depending how much your mechanic charges you) mine did it for free and he found out why the engine light is on afterwards too. so to fix all these lights (abs, trac-off, and service vehicle you MUST get another ABS cable (i went to a garage, they were towing a GM vehicle to the junk yard so i grabbed some scissors and cut BOTH abs cables on each side (good thing i did because one was bad) and braught them to my mechanic. the reason the lights come on is probably a defect or in my case my mechanic said it was salt buildup in the wires (on the drivers side) so he cut the wire off and rewired the new one and BOOM all the lights came off (service vehicle, abs, and trac-off) now for my service engine it says catalytic converter but im trying to put some fuel system cleaner to help it out i read somewhere that this is a defect of the car, so if you dont have that light yet, SELL your car ASAP for as much as you can get for it (after fixing the lights of course) and always google (car name+recalls) in the search bar to see what youre getting into, take care

awd disable is usually a $200 tube type sensor in the rear diff. abs light is usually front hub bearing

Hi, I can help

You have a bad wheel bearing assembly.
The bearing is starting to seize up, and it is telling computer there is a problem in ABS system, as well as AWD system.

First thing is to locate which bearing it is in the front end of the vehicle.

1)Jack up each side of the front end, place a safety support stand or jack stand under frame of vehicle.
2)Once vehicle wheel is free from ground spin the wheel and listen for grinding.
3)Compare each wheel as you spin and make your best judgment on which is more noisy.
4)This is your problem wheel you need to remember which side of the vehicle is the source of problem when ordering the part from your local auto parts store.

To repair: Remove wheel, remove brake caliper, then brake caliper bracket, then the rotor, remove center axle nut, then remove bolts for wheel bearing hub assembly.
Your ABS and AWD lights will reset themselves upon successful test drive following repair.
Let me know if you need more assistance or pictures.
Good Luck, have a great day.

Most common repair to solve the problem is replace flow valve on the rear differential and also replaced 4 pints of VersaTrak at the same time. (I'm a retired GM engineer.)
