Traction control errors...

[wendal]

A friend of mine with an 07 Avalanche did his hubs / bearings, and has been getting traction control indicators ever since. I told him to unplug and plug back in. Did not help. What else could be wrong? I read stuff in the forums about this but I can't find it now. Any suggestions would be greatly appreciated.

check the abs sensors, sometimes there bad out of the box (especially the aftermarket), trying swapping the old abs sensors on

^^^^must be something with one of the abs sensors. If you can get ahold of a good scan tool it will tell you which one.

Thanks guys, I will pass this on. If you can think of anything else, let me know.

Bent pin, loose connection. You can measure the resistance of abs sensors and see if what the ohms readings are. If one displays OL that’s likely the one that’s the problem
