Any help would be appreciated. This only happens when at a stop while turning the wheel when accelerating. All wires going to the hub assembly are OK. No codes shown anywhere. I'm at a loss as to the issue.

Save some time... goto GM and pay them to diagnose it... they should be able to track it down in less than 30 min...

I would, but my dads been an ASE master tech for 25 years. He has never seen this at all. Not a single code active or stored in bcm, tcm, or ecm. The only thing I can think, is to replace hub assemblies, and cv axles again(both changed 25k ago) and see if that helps.

you need a scan tool that can read the signals from the wheel sensors in real time as you drive the vehicle, if the signals are being interrupted then you know its a wiring or sensor problem. Otherwise this could easily be a bad EBCM.

his dad must have or have access to that tool spawne,or like red zone says got to take it to dealer

is that the electronic brake control module? you wouldnt happen to have a part numer eould you? i looked online and couldnt find anything.

we have a matco pro scan 2 at the house and i believe they have a solus at his stealership. we did check all wires going to the wheels and everything seemed to be ok. i did get the pos advance cv axles that i now know are worthless. and the driver side axle does have a little bit of play in it. but i wouldnt think that would cause this.

did u go to gmparts.com?

superglide9375

seen some antilock brake modules on there 160-250,2 kinds but call them and make sure,i got my airbag modules from them and they are by far cheaper than dealer,gm parts too

steve06mcss

thank you, thats good to know. ill check it out after i get to work. im just baffled and i dont want it to ruin my trans. any idea how hard it is to change?

superglide9375

i wouldn't know,but look at diagram its also on eBay ,i would still scan it it first,a lot cheaper to do wheel sensor,if thats what is going on-u could throw parts at it all day and guarantee its the last part u put on so get it scanned and go from there

steve06mcss

oh i was going to scan it first. i was really worried it was the body control module. i know that a headache to take care of and was not looking forward to that. i appreciate the help guys!

steve06mcss

i looked on gmpartsdirect and ebay. all i could find was the ecm, tcm, and body control module. maybe its the body control module and not electronic brake control module? excuse my ignorance, im not an electronic guy by any means.

not a problem, i get weird intermittent abs activity similar to what you get sometimes when coming to a stop, the abs will pulse for a second and then disappear, no codes. Replaced the entire harness assembly and hub on the right side with no luck. I also have a feeling my EBCM is damaged from when it shorted out, i had it repaired but it hasnt been right since. Unfortunately the replacement for the GXP is 1000 dollars. lol

steve06mcss

Man!!!! I would wait to if mine was1000 dollars. Lol. We are gonna check connections this weekend. It's been going on for six weeks. Then out of the blue today, it won't do it for anything in the world. Lol. Just my luck, I get advice, then the problem stops.
