2012 Chevrolet Impala C0035 Service StabiliTrak/ABS/Brake System Fix

2012 Chevrolet Impala was throwing an ABS/StabiliTrak/Brake System code for C0035 - Front left wheel sensor malfunction. I replaced it with a Timken Wheel hub, problem went away. A few weeks later, it came back, but harder. Figured the Timken took a dump, nope, it was the wiring harness. I must have gotten lucky when I unhooked it, I "temporarily" repaired the break in the wire so it worked. This time, I confirmed it is perfect.
I honestly think there was some foul play from the car's main mechanic as it looked tampered with, but not sure.

[@user-jy6lc4kg4l]

The abs/wire harness for the Chevy impalas are too short so when you turn it pulls the wires apart. Common issue. Thanks for the video!

[@douga91965]

Is it possible that a faulty Stabilitrak system will trigger a TCM failure code? Mine seems to be related, trying to figure it out,

[@sshaver2302]

This is incredible. I'm hoping that's what'ss wrong with mine. I also had 16k at purchase 3 years ago, and had these errors on my weekend test drive just before I purchased it. The dealer repaired it no cost. Now, at 165k miles, it's coming back. Thanks for posting this!

[@norseman8727]

The worst thing they did with new cars is put all these sensors and wires in them . They have it engineered where a code will come on every six months , so people have to bring it to the shop and spend unnecessary money . I've got a Chevy Impala LS 2012 and the ABS light is notorious for coming on . Great video 👍

[@kirbyyasha]

Ack, since I have serviced this Impala, it has been off ever since. Using the AC Delco Wheel bearing/hub assembly, along with repairing that broken wire, the car has been great for my grandfather. But it does sound like these GM's are just built with cheap quality. Which is sad, it's a very nice car.

[@norseman8727]

@Mike Macc Yep it's prone for it , it's happened to me multiple times and I've known other friends that have had it happen on fairly new cars .

[@mostdopecaptain3350]

I have a 2009 that’s had the service stabiltrak and all that junk lights on for 5 years now, driven it about 200k miles across country in the last 5 years with those lights lol. Recently bought a 2011 with only 75k and after putting 6k on it it’s lighting up like Christmas. Typical chevys😂 but I keep buying them because it’s usually the same 5 or 6 issues and that’s it no mystery bullshit. Either your wire sensor is bad, your ac actuator is bad, your power steering/brake fluid is low, or your transmission is blown😂 that’s about it with those chevys but if you take care of them they’re all good

[@huckster66]

Nice video! Have a 2012 same issue. Will be my project for the day! Guess this is a common problem with the impalas. Should be a “recall” issue for GM! Bought the wire harness from “Rock Auto”, for $6.50 complete. GM wanted $70.00! A lot of people replace the hub bearing and nine out of ten times it’s the WIRE HARNESS!👍

Sweet. I didn't see anything wrong with my wires and almost bought a new sensor. First I did like you and ran the car on stands until the light came on and found the issue

[@deefootwork_]

What was the issue if you don’t mind me asking

[@scotttrinca2429]

My 2012 impala was doing the same thing and I found out the sensor wires (like the ones in this video) were zip tied too tight, so every time you turn the steering wheel all the way left or right, the zip ties didn’t leave enough slack in the wire to compensate, triggering the 3 wheel-related (ABS, stibilitrak, traction control) warning signals. I simply cut the zip tie anchors but still left the wires it in the raceway and I’ve had no problems. Thought this would be very cheap and helpful

[@makeaway6430]

Does service traction control ever put the car into limp mode or is it om to drive like that?

[@makeaway6430]

@Richard Skipper i just turned of the traction control and haven't had any problems.

[@douga91965]

Is it possible that a persistent Stabilitrak issue can cause a TCM code failure?

[@ezwa9979]

I noticed you, like many with this subject, never route the ohms tester towards the main ABS regulator gizmo.. makes sense cause I tried it & no reading on either front side. guesscing that means the loop is closed at regulator when battery, key, etc., is shut-off. same differance though, 1 could start test from connector closer to regulator & point it back towards hub. btw., these wires internally breaking on this wire is a common misnomer - something about after one breaks, then takes off on a turn, that’s when stabiltrak, this that or the other, takes place - almost like, maybe, heat from exaust, brakes, etc. puts tension on wire then when turning, etc. it pulls this now, non-fascined connection apart. from that one could guess this hidden break is near brakes(no pun int.)✋😒

[@TheHuskyGT]

This is a persistent problem and I don't know why. I've had two Impalas, a 2007 3.5 LT and a 2013 3.6 LT and both had the same issue. To this day I just replace the harnesses (they are like $20) every year, which is about how long they will last. I don't even bother buying Doorman or AC Delco, as these are not only more expensive, but won't last any longer than the generic Amazon brand. Replacing it takes just a few minutes. Never take it to the dealership as in some cases, it won't throw any codes. It will just randomly activate the ABS and TCS giving you those nasty vibrations and slowdowns when turning. The dealership need to be able to replicate the issue and most of the times it won't do it. Worst case, they will tell you to replace the ABS module or wheel hub/speed sensor assembly and these are VERY expensive jobs, plus they won't fix the issue.

[@AllThingsAnime2]

When you say expensive, what’s the cost?

I have had this issue for the past 2 plus years on my 2011 Impala. I've had it fixed several times and problems keeps reoccurring. What's the deal with that?

[@kirbyyasha]

In my case, it was a defective wire. But I have heard these cars are prone to bad wheel bearings. If you're putting on the garbage from the auto part stores, those might be part of it. I Find GM's are picky when you don't use AC Delco. But that's my experience on it.

[@RuffmanTravels]

Did this error code caused all the gauges to shut off driving and then come back on and keep shutting off? Taking to mechanic tomorrow and I’m going to show him this video. The idiots at GM kept my car for three days, charged me $150 for a “diagnosis”, and then proceeded to tell me they didn’t know what’s wrong. Thanks for the video!

[@kirbyyasha]

The gauges never had a problem. The error was while driving, because of the bad wire, the system would receive input from the wheel, then lose it, when it lost communication with the wheel, Service Brake System/ABS/Brake Traction Control all came up at once. The speedometer kept functioning normal. If your gauges are going out I'd suspect a different issue.

I've replaced all four hub bearings on my 2012 Impala and I still get abs issues. When I turn to the right and accelerate when in first gear my brakes lock. What are the odds the wiring on my right hub bearing needs replacing? Also do you have to splice new wiring or can that be bought and replaced just like battery terminals can?

[@martinneri5136]

@@ferrer65 does it have abs code? Bad hub cables can mess up the braking and taking off of the chevy cars

[@ferrer65]

@@martinneri5136 I've realized that when I went into a forum online. I ordered the abs cables from autozone. The dealership wanted $127 a cable. Autozone had them at $45 plus tax. I'm going to take the car to the mechanic next week. In the meantime I've discovered that turning off the traction control completely eliminates the issue. It really only happens at low speeds. Particularly in my car when I make sharp right turns. Not so much when I turn to the left. Sometimes if I hit a pothole in a parking lot it happens as well. Doesn't seem to be an issue on the highway or if I turn while braking from a speed higher than or cruising at ~20 mph. I'm honestly kicking myself for not looking into it sooner because I feel like I've wasted money on replacing hub bearings that probably didn't need replacing. And I went to three different mechanics who all recommended the same thing. No one hit the nail on the head. Honestly GM should produce better vehicles. Don't think my next car will be an Impala.

[@dariusknite]

What is the part number for the part needed?

[@kirbyyasha]

The part I used was actually scrap wire from another car I gutted. Actually came from a 90's Ford Thunderbird door harness. I ended up cutting and replacing the wire by soldering, and heat shrinking it between the body and the wiring harness pigtail. If your pigtail is damaged/defective, might be able to get one from a GM Dealership by specifying the ABS Sensor wiring pigtail.

[@AlexvrbX]

Might depend on year and submodel, but you shouldn't have to go to the dealer. For my 2008, the rear ABS connectors and wiring is Standard Motor Products part number ALH73. That one services both rear abs wires and has all the clips and connectors, plug and play. For the front connectors, Standard N15002 is the repair harness, one per side. That one will require cutting and reconnecting to the old wiring further up. Double check with your local parts guy. It appears to lightly coil the wire for better durability vs the factory wiring.

That isn't even a fancy reader, can be had for pretty cheap on ebay/amazon. Though the sad reality to fix a lot of problems with modern cars you need some diagnostic tools. However, if your car has a sporadic Service StabiliTrak/ABS/Traction Control error, could play with the wiring harness to the wheel to see if possibly a bad connection with the car in drive while on jack stands to see if you hear the car beeping. Then you know you have a wiring issue and just have to figure out where the break is and repair the break.
