Service Traction Control & Brake Assist?


Recommended Posts

I’ve got these two messages coming up on my DIC display, along with Traction Control Disabled. I’d like to check the codes, if there are any to help with diagnosing problem location, but I cannot figure out how to do this on my 09 CTS... this is a different method than older Eldo & SLS I had, it seems. Any help appreciated! 

I suspect this issue is with the new 20” wheels I put on, as they don’t seem to be balanced correctly and probably shook loose a wheel speed sensor or something? Boy, do they look great though!  LOL 😝 

I’ll post some pics in separate string soon hopefully!  👍🏻

Buy a CAN capable code reader and check the codes, I bought a $50 one at pepboys.

Make sure the bolts aren't bottoming out before the wheel is tightened.  

Try a road force balance.

Does this wheel/tire combo have the same revolutions/mile as the OEM Setup?  Check this

Thanks Mike, 

I know, I need a more updated code reader, mines prob 15 years old!  Can’t figure it how to do it onboard though...

Yup, I had checked and the lugs are tightening up just fine and the wheels run true... the prob is they’re worn badly on inside edges of all tires, cupped as well... I ordered new tires today and will be road force balancing all of course.

You can't check codes on board from about 2005 when they went to CAN

Well, haven’t fixed it yet but almost certain is rear passenger hub now. When reinstalling that wheel after painting brake calipers it was obvious it had a crunching/grinding noise when turning wheel. Checking records other side was replaced at 96k mi  and has 113k now.

Its going in Tues. for mounting new tires so I’ll have the shop take care of it. Have no time myself unfortunately and need to have it every day for commute.

 Just realized I never followed up on this repair. It ended up being the right front hub/sensor that was bad. We replaced that and all is well! 

 Really happy with the way this vehicle rides and handles with the 20 inch wheels! Was a little concerned that it would be kind of rough, but it really is quite a nice ride! 😎

Glad to hear.  What was stock?, 18"?

Any change in wet handling? What tires are you using?

Oh, stock size was 17”.  I went with the 20” tire size that would keep roughly same dia. to keep stance same and speedo accurate.

Very interested in how the handling and ride characteristics may or may not have changed both wet and dry.  Nice job
