Can't find any DTC's 2009 Duramax

[JordanSBC427]

Hello,

I am having some issues with my 2009 GMC Sierra Duramax. My service traction control, service trailer brakes, and service stabilitrak keeps ringing in. I have read that the most common issue that causes this is a faulty wheel speed sensor. I tried hooking up my scanner, and checking for DTC's but when I hit shift+F8 it says no DTC's are present. I assume that it will be the E35A/B LMM/LBZ computer module that my vehicle will have. Any one have any ideas or know of something that I might be missing? Even when I hook up just my scanner without my laptop, I can't usually detect any DTC's. Any help would be greatly appreciated.

Thank you,

Jordan.

Disregard this post, issue has been resolved.

What was the cause...?

Had GM scan the truck for free and issue was with the right rear wheel speed sensor. Spent lots of time trying to determine why my scanner would not show the code, but I assume its because EFI Live strictly does ECM and TCM correct? I believe this DTC resides in the BCM.

EFILive has an option to read DTC's from all modules on the serial bus.
