2010 SS, Stabilitrack WITH ABS light

Motor is running fine and appears to have no performance loss... I checked spark plug wires to make sure of positive connection.

I took out all of the wheel speed sensors and checked them and cleaned them also checked the connections on the inside of the firewall and the the connections in the rear end as well, they all visibly look to be fine "not broken etc"...

I put everything back together and still... all my lights are on

ABS, traction control, sport mode etc... no check engine light.


Someone help me out this is driving me bonkers.

Update:

1. Pulled fuze #40 looks perfectly fine
2. Checked ground wires everywhere, all appear to be good.
3. Battery voltage when car is off is 12.5ish and 14.5 when idle in the drive way.
4. Cleaned each speed sensor and checked for cracked wires
5. Checked the connection from speed sensor to plug.
6. Disconnected Battery several times to see if it would reset.

My local stealership, I mean dealership does not have the most outstanding track record, in fact there terrible.

What other options am I looking at now? Could the wheel speed sensor be bad and look fine? how to check

I saw a youtube video of what looked like a ring on the back of a hub where the ABS sits and it was cracked and missing??? causing this issue on a v6 car... Not sure how to visibly check this unless I take everything under the sun off and visually look at it....

When i first got the Vitesse Throttle Controller (VTC), it caused this exact same symptom you just mentioned (July 2016). It did not trigger a check engine light at all but all the abs, service stabilitrak, traction control off lights all came on and stood on. Hooked up the tech2 scan tool and bcm was saying the "brake module" and "yaw rate sensor" were bad. My local tuner said the reason the check engine light didnt light up was because it wasnt emissions or engine/transmission related. Off the bat he said the VTC's signal was not what the car's computer was expecting and that THAT was what triggered the stabilitrak lights and added that the yaw rate and abs need the signal from the accelerator pedal to the throttle body to be consistent in order to be able to properly control the engine speed/timing in the event of acceleration traction loss/panic braking/wet condition sliding. He recommended that i not erase the BCM trouble codes and instead remove the VTC and let the car cycle for ~200 miles and that IF the VTC was the issue, the BCM would shut off all the lights on its own after it no longer sensed the incorrect throttle signal. So I removed the VTC, drove from Los Angeles to Riverside and back and the lights all turned off after about 220 total miles and havent returned ever since. Going on 10 months now.

To the above poster, I'm not sure what your referring to when you say the name of that controller. Is that aftermarket??

So it could have something to do with my throttle body? This issue occured very very shortly after my cam/ TB install and has been that way ever sense.

I should add that to the list, I have also disconnected the Battery several times.

Some other symptoms that may be worth Noting.


1. When I start the car the DIC is shows stabilitrak, lights etc. I roll out of the driveway at slow speeds and they all go off for a brief period maybe 5-6 seconds, and then it pops back on. I hear no surging or anything from the ABS module.
2. This only happened one time, but I should mention it I guess. I started my car one day leaving work and it actually went about 14 miles before the issue occurred. 99.9% of the time, the above happens.

There are so many threads on here with this problem, yet no one has really figured this out... or have they and not posted?

I'm out of ideas... except to take it to my sub par stealership... what to do.

from experience, i would recommend you have the car checked by a tech 2 at your dealer to read the data from the body control and brake modules. A regular hand held engine DTC reader will not read these. I've seen this kind of scenario happen from a bad hub bearing in the rear causing an overactive ABS sensor reading. That is the best advice i can give you. Your chevy dealer wont erase the BCM codes unless you get the issue fixed and if you decide to take it to a normal average joe shop, dont let them erase the codes unless they've 100% identified and repaired the problem. Take it to someone you really trust if you arent going to take it to the dealer to check BCM data

Efi alchemy in green cove springs did my cam and tune.


I guess I have to suck it up and take it to the dealership,
They just quoted me $140 plus tax for a set of factory
Spark plug wires. What a joke :/
