equinox 2015 stability and traction control light intermitten

[ycjf]

equinox 2015 4 cyl awd 170,000km, traction control light and stability control light comes on frequently for only about 5 to 30 seconds (while driving does not happen on start up), no stability or traction service message, no engine light, no abs light, no erratic engine issues, no abs code or engine codes where do I start troubleshoothing? Thanks for any help.

 

[Hey Vern!]

check and clean the wheel speed sensors and the tone ring. It could be a bad sensor, bad ring or bad control module, too.

Good day Vern, if it was the case shoul nt I get an abs light as well? and a code for the faulty sensor or ring? Thanks

I would say yes if the ring was caked with rust or dirt, but if its only in a few places, maybe not. It is just seeing a discrepancy between the wheel speeds or at least that is my thought.

Thanks that is a good thought, is it possible to check the the ring without dis -assembly? perhaps with a inspection camera?
any suggestion? it would quite a pain to disassemble the 4 assy to check.

Thanks again

I have a 2012 and had all traction control lights on, I first swapped all 4 sensors at the wheels and that didn't fix it. I got a better code reader and found out that it was the abs module, witch is not easy find. I found one used on eBay and replaced it and then took it to a Chevy dealership and had them program it to the car. A couple of hundred dollars later and everything is good.
