Question about 2002 Buick Century
Anti-lock brake lights came on, so put new anti-lock brakes on the car. After that the anti- lock light was still on and so was the service vehicle soon light. Can't figure it out.
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

If the wheel hub does not fix it the problem is more than likely the wire harness for the wheel speed sensor is bad. around 70 bucks for the wire

The real problem with many 2002-ish GM (Chevy/Buick/Olds/Pontiac) ABS light on is that the wiring running from where the Wheel speed sensor is plugged into all the way to the ECM is bad. If you have this issue take and pull the wires out of the loom near the wheel connector and pull with some force and the wire will just break! You will see black crumbly wire inside the insulator. GM used low grtade wire for these wires and with age they just crumble. They need to be replaced! The whole wire from the connector at the wheel all the way to the ECM. The ECM end is a danger spot for the untrained person so get professional help on that end. This will solve those annoying ABS, Service lights once and for all. Show this post to your mechanic if you have to keep going back for a returning ABS light.
