2001 Buick Century ABS, TRAC OFF, SERVICE SOON lights after fixing hub

It needs to go a scanner. To check for codes and to see what isn't working right. The service could be as easy as a gas cap, worse case a transmission. The abs could be a wheel sensor/hub or a broken sensor wire.

check the ABS sensors in each wheel may be dirty clean them but may have to clean the pick up in each wheel as it is teeth fitted to the shaft.

could be a bad wheel bearing for the abs and trac light not sure about engine light you need to have someone scan the abs and ck engine light

I think that the ABS TRAC OFF light has more to do with the ABS sensors not giving reliable speed or movement information to the ABS Control Module. Harness connections or broken wires to the module can cause the same problem, or the hub assembly ($49 to $79 to $109 for the part) may have to be replaced to start with.

The driver door window switch not functioning correctly may be a bad or dirty switch which can be obtained from a salvage yard for a lower price than from the dealer. I would test the switch current before replacing, though, with a test light to ensure the wiring is not an issue with this circuit, as well.

Good luck on these repairs on the 2005 Buick Century.

I just put in new fron pads in my 2000 buick century and the track off and the anti lock brake light and the service engine soon stays on

ABS sensor in your hub is bad

Its most likely a bad front wheel bearing hub assy.. Get a scan on it and see if it comes back as a speed sensor on either the LF or RF... If so.. Its a bearing

Are you sure of the lights? If it is Service VEHICLE Soon, in addition to Trac Off and Anti Lock, it is most likely one of the four wheel hub assemblies. These are sealed bearing units that feed a signal to the computer for the ABS brakes and the tire pressure system. I had one go out intermittently (seemed to be aggrivated by humidity/moisture). I had it replaced, and another one is going out. It seems like they are a bit prone to failure. My Century has 101K, and I experienced the first one around 75K miles. Unfortunately, to tell which one is failing requires a scan tool above and beyond the simple one that most parts stores use. BTW, there was a problem that was fixed just prior to 2002 that was caused by the signal wires going to the left front wheel hub being worn through and shorting. I believe this problem was fixed by 2002.

THATS IT JUST THROW PARTS AT IT

your traction control works off of the abs unit did your abs light come on also? if there is a problem with the abs it will shut off the traction control. might wanna have the abs system scanned for trouble codes.it is also possible the conditions you were driving in caused erratic readings so if it has not come back on it is probably ok

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
