Thanks for choosing Just Answer . I'm Wolfgang here to help!!

I am confident we can resolve your problem together. Please
understand that I don't know your skill level. In most cases when you have a problem
with the way the vehicle performs, specialized tooling is required to acquire computer
data/information or engine testing results. We didn’t build these complicated vehicles; we
just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results. Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!! I am also going to direct you with the fastest, easiest and most common things to check first. Please be
patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in
return. I will also continue assisting you after you have rated me, if necessary. If there
is any reason I cannot get a positive rating, please let me know why “in advance”, so I
can go another direction for you. I am sorry you’re having this problem; I’ll help you
through it.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

I do need some more information.

Any recent repairs to the vehicle before this issue started?

how is the tread depth of each tire ?

thanks

Usually when you have an unexpected abs activation means that either you have a speed sensor getting weak

Chevy Mechanic: Wolfgang, Master Auto Tech replied 8 months ago
when it gets weak then it looses speed signal and then the module reads as a wheel slip
Ask Your Own Chevy Question
Chevy Mechanic: Wolfgang, Master Auto Tech replied 8 months ago
A scan tool is needed to monitor the signals and the signal that drops out is the sensor to replace. Unfortunately a scan tool is needed and a professional one is required

I have an unonova scanner but I have not used it so I don't really understand it I guess used to working on older cars without computers
Chevy Mechanic: Wolfgang, Master Auto Tech replied 8 months ago

some code readers will not read abs modules for codes .

I already had $36.00 taken out of account and got no where
Chevy Mechanic: Wolfgang, Master Auto Tech replied 8 months ago

I try to help out as best as possible with the information given . I have stated that special equipment you may not have may be needed to narrow down the issue. By any chance did you try autozone or advanced auto parts they have better scanners that they can scan ?
