Have not, took it to auto parts store to use free scanner only to be told their scanner wouldn’t pick up codes as it seems to be a
Ground short of some sort
Chevy Mechanic: JOHN aka Eauto, The Car Guy replied 7 months ago

likley they did not have a enhanced scanner it has to have abs capabilities or it wont work... most parts guys are not techs so if you follow a parts store advice you will be chasing your tail

Any ideas?
Chevy Mechanic: JOHN aka Eauto, The Car Guy replied 7 months ago

a scan tool with abs functions is step one can you verify what make and model scan tool was used to see if it will even retrieve these codes?

Did not use code reader at all. Said it would not pick up codes so didn’t bring it out
Customer reply replied 7 months ago
It seems to be a common problem on these trucks but all my searching has taken me from bad battery cables to bad grounds.
Chevy Mechanic: JOHN aka Eauto, The Car Guy replied 7 months ago

well i would suggest buying or renting a scan tool with abs functions first...

THE ABS Light or traction control comes on when there is a fault in the abs system. When the light is on the abs system is not working..A diagnostic scanner - computer would be required to pull the trouble code and to diagnose./.The failed component would need to be repaired or replaced to get the light to go out. likley you have a wheel speed sensor or wiring issue to a sensor

if you can get me the trouble code..i can lead you to the cause of failure

I see, also, when coming to a normal stop it seems like abs activates
Chevy Mechanic: JOHN aka Eauto, The Car Guy replied 7 months ago

that is likley a bad wheel speed sensor generally this happens when one of the front wheel speed sensors fail
