Did you plug the sensors back up?

    Replacing the harness is a big expensive job. I would clean up the rust and apply some dialectic grease to the plugs.

Service abs system light comes on all the time. both front wheel bearings have been replaced, abs light stays on.

i had the same problem with my 2005 chevy uplander. the ABS lights kept coming on. The fix for me was... I had a damaged and old battery(the original battery). If your still under warranty or not I would suggest you check this out by using a new battery to see if this is your solution.

Well, start by repairing the obvious issue. ABS sensors are located in the same area, so when the bearing fails, metal filings go everywhere and mess up ABS sensing...

All Wheel Drive Disabled

I would take it back to place where it was repaired, it is possible that the part they replace is defective..

Also they should have clear all codes in the system at that time!!!

How do i turn off the abs light on a 2005 chevy uplander? replaced front pads and checked wires and connections. is there a way to see if the anti-locks are working?

Hello Abintz.
When your ABS light is on you have a problem in the system.
As long as the light is on your ABS system does not function at all.
If you have already checked the harness and connections the next thingt you can check yourself is resistance values at the wheel speed sensors.
One at each front wheel and one in the output shaft housing to the rear drive shaft.
They should read very close to 1000 ohms.
The front sensors are usually the area of most problems I see. They are replaceable.
Other than that you really would be hard pressed to find any other issues without getting it scanned by a repair shop.
If you have further questions please put them in "add comments and I will return to answer.
Best of the season to you.

2003 chev. silverado2500hd, abs goes off, pulsates when stopping

Gm has tech service bulitens on this issue.First the abs sensors can and should be removed,inspect the sensor mounting surface for rust (clean w/ sandpaper) insp the sensor (note the sensor may break w/ trying to remove so be gentlel) if all looks ok reassemble and test drive. if unwanted abs still persists both hub bearings should be replaced (call your dealer and ask if a special policy exsits for this condition) usually no abs code w/ be present Good luck Ray..

2007 Chevrolet Uplander LT ABS and TC light on

We were having this problem...have your wheel bearing checked out. There was a sensor in the drivers side wheel bearing...once we replaced it (because it was going out) the ABS and Traction Control warning lights stopped coming on.
