Traction Control and ABS problems:
Sometimes the copper inside the insulation of the wires going to the sensors corrodes. Especially on the front units. It reads more ohms than normal but not open and is very intermittent. However moving the wires my make it work for a while. That's why replacing bearings seems to fix the problem but it comes back after a while. May NOT have been the bearing to start with.
I went to the Chevy Dealer parts department after reading this post and purchased the left side ABS Brake harness, GM #10340314 list price around $79 less discount. Amazing that they had both the right and left ABS brake harnesses in stock. Guess it is a common problem! My car also had the ABS brake light coming on with left had turns and then the error would shut down the abs brakes. After cutting off the old harness I found the corossion of the cooper wiring and the same at the abs connector plug. Anyway I also live in the Cleveland, Ohio area and the road salt must really do a number on the wiring. Funny in that the dealer mechanic was at the window during my purchase and he appeared shocked that I was making such a parts purchase because it must be an inside the inner cirle kind of fix, not known be the general public. I also saw the TSB for this problem posted.

The dealer/mechanic just doesn't know, we all are having this same problem all the way up to the 2005 models. My trac and brake light have been on for awhile now and I just leave-never took it to the shop, personally it doesn't bother me at all cause the car still works. And from everyones posts on this site, I figure I'm not going to waste my money for a temp fix. It doesn't effect the vehicle at all. MY SUGGESTION IS TO UNPLUGG THE FUSE FOR THE TRAC AND BRAKE LIGHT AND ROLL-ON!
Better to buy and replace the front left traction control wiring harness from the dealer then continue to roll on without the problem. Yes you can leave it alone but it is annoying and I got tired of explaining the problem to people riding in my car. Cost of the part about $65.00 and about a half hour if you have the necessary soldering iron, black electrical tape and basic tools.

i was looking at the problem on google and found one persons solution. he said to check front sensor wiring for breakes. i did and found one wire broken on right front harness about 4 in. from speed sensor connect. repaired wire and so fare has fixed problem. gm used a hard plastic wiring cover it breaks over time causing wire to break , it should been a more flexable wiring harness. gm should come out with a wiring kit to fix sensor harness

I have been in to the dealer twice now for my traction light coming on. the first time, they replaced my left front speed sensor and it seemed to work for a few months. mine seems to be affecting my brakes alot this time to the extent where the car is harder than normal to stop. Maybe chevy should consider asking the Japanese how to make their cars better.
Yeah, they should call Toyota cause they do such a great job of solving stopping issues.

A sincere thanks to everyone for participating on this discussion thread.

I had the same problem with my 06 Impala SS with 145,000 km (66,500 mi).

Turned out my problem was caused by a break (within the insulation) of the yellow wire in the front left wiring harness, a couple of inches from the connector.

I soldered about a foot of 16 Ga wire, replacing both wires from the connector, to where the wiring harness clips to the subframe. I soldered all connections, used shring wrap, and wrapped the wiring in electrical tape. The clips holding the wire to the lower control arm snap open easily. As well, I reused the split loom wiring cover.

The problem showed up several weeks ago when traction control would come on when accelerating on dry pavement with the steering wheel turned either to the left or right. It rapidly progressed to "Service Brake Assist" (with the double chime) and "Service Traction Control" messages popping up on the instrument panel. As well, I had the Traction Control Off and ABS Off Lights come on. These lights would turn off when the engine was restarted. The last straw was the ABS engaging as I was braking gently on dry pavement - I could have run into another car!

Took the car into a local shop. They 'diagnosed' the problem to the front left hub. Problems continued almost as soon as I drove the car from that shop.

Thanks to this forum, with the car on the ground, and the steering wheel turned fully to the left, I was able to reach in and wiggle the harness on the front left lower control arm. Every time I wiggled the harness, the "Service Brake Assist" message and double chime, would come on. That clinched it!

One other thought - it looks like there is excessive flex of that section of wire between the rear-most clip on the left lower control arm and connector, when the steering wheel is cranked fully left. A nasty U-shape is formed. When installing the new wires, be sure that bend is minimized, while at the same time making sure the wire is not stretched when the steering wheel is cranked fully right.

I'd also add that most people posting here have the previous-generation Impala (00-05 Model Years). With my vehicle, it looks like the problem has been carried over to the current generation Impala (Model Years 06-11).

Pity that this has not been identified as a recallable action by NHTSA and Transport Canada - there is a real risk of rear-ending collisions as the ABS activates in error. But then again, this is "Government Motors" we're talking about, not the Toyota "whipping boy"!

Also pity that the repair industry is in the parts swapping business, and will not take the few seconds to wiggle some wiring. I'll bet millions have been spent by frustrated owners over the years on un-necessary repairs.

Thanks again everyone for your help!

I too am having the same problem with my 2002 Impala. I thought it was just my car until I read all of these posts! I purchased this car brand new and have had some costly things to fix. I have 156,000 on it and now this just started 2 weeks ago. I too live in a snowy, salty area. I'm so glad a read all of these because it will save me some serious money! Thank you everyone! P.S. I'm sure you have all had the problem with the windshield wipers being stuck in the upright position? I see it daily on Impala's in my travels. lol.

I had the same problem with my 2005 Impala. I took it to the dealer and they found one front hub was worn. They also found the bearings were worn out. They replaced the bearings and the defective front hub. The problem is gone. They also said the infamous steering shaft had to be replaced and relubed. The front steering shaft is a known problem with these cars. When replacing the steering shaft be sure to tell them to install the new and updated steering shaft. At the dealer, I was told my ABS light and service traction control system light was on the same time because of a multitude of problems. The front brake pads were worn, the hub, wheel bearings, and steering shaft were all contributing to the problem.

If you are replacing the hubs be sure to install only GM parts since the aftermarket hubs do not last on these cars.

The dealer says there is no defect and that I am the only person that he has ever seen with this problem.
My car is a 03 impala and does the same exact thing. IT is reliable but continues to do this.

[my 2003 Impala does the same thing. I turn the traction off and it seems to be better but now the brakes seem to jump when making a turn. If I don't turn it off it's alot worse.

Remove the ground wire for the ABS device. Drill an new hole and reattach the ground. The original location was not good, prone to rust.

My 2002 Impala started leaking power steering fluid from the power steering cooling line. Not a great do it yourselfer project because the subframe needs to be lowered to gain clearance. Dealer cost of replacing rusted out power steering line and rusted oil pan together over $800 with a couple of coupons. I am not crazy about using the dealer but I needed if fixed fast and properly. I guess it is not bad for 185000 miles in the rust belt. The salt eats everything including the transmission lines which I had replaced myself for around $65.00

GM did come out with a repair harness to fix this problem. I think it cost about $60.00 for each side. It takes about a half hour to fix. Remove wheel. Remove a small inner wheel well cover, splice and solder, retape splice and remount new wiring harness after removing enough of the old wiring. Replace inner wheel well cover and remount wheel.

STOP SPENDING MONEY ON UNNEEDED PARTS, EVERYONE!
I have had the same traction control problems, intermittent, for a year and a half. Codes showed problems with the wheel bearing up front and/or back. Replaced the one that the code pointed to and the problem came back within days.
Long story short, a thread suggested simply cleaning ALL connectors (at each hub) with electrical connector spray. I did so and, incredibly, the problem is completely gone for over two months for the first time in years! Spray cost $6!
Also, the wiper issue stuck in the upright position is due to a metal tab in the wiper motor getting bent to the point that the swivel action makes the tab "miss" its engagement. In other words, take everything apart until you can SEE the motor and find the metal tab that looks worn from years of service. This is the tab that needs to be bent back (pry bar and hammer worked for me)
Hope this helps!
