2017 Silverado - ABS and Traction Control Lights, Right Rear Turn failure warning, random battery draw

[jpfister]

Hey Guys-

 

  I am struggling with multiple issues on my 2017 Silverado. The symptoms started with a warning for Right Rear Turn signal failure, although it lights up and works fine. Then the ABS, Traction control and Trailer brake lights and warnings came on. They randomly come and go when I start the truck. Most recently, something is staying on and draining the battery. The Battery draw will happen randomly as well.

 

   I have read thru previous similar issues, and most related to ground issues. I have checked and cleaned the grounds G101,G102,G121,G141

 

  I have tried to locate grounds G210 and G218 and they do not appear to be located under the dash panel on this year like others have found on the 2014 models

 

   I have 2 codes: CO110 and CO800

 

   Has anyone experienced similar issues, or do you have any guidance on where to go on this issue?

 

    All of the issues will come and go, but are becoming to be more regular.

Right now I’m researching an issue where I’m getting u0073 codes inside my EBC and SAS modules. Found what looked like a fuse that got really hot but rings out (ABS Valve? Fuse 25 25A). Now need to look at grounds.  
 

Need to find something that shows all ground locations as well.
