No DTC's Being Displayed

[JordanSBC427]

Hello,

I have a bunch of issues popping up on my dash, "Service Trailer Brake System" "Service Stabilitrak" "Service Traction Control System". I have hooked up my EFI scanner and cannot seem to find any DTC's at all....I feel like the scanner is not picking up all of the vehicles modules. I was reading in the V7.5 scan pdf that you can configure your scanner to use passive module detection or active module detection. Would this possibly be an issue?? It has an H&S tuner that plugs into the OBDII port but I would assume that wouldn't bother anything, as I unplug it to hook up anyways. The truck is a 2009 GMC Duramax 6.6L, which is i believe is the LMM. I will attach a few screen shots of what I have for modules that are displayed but I feel like something must be wrong because I would assume I would have DTC's being thrown.

Looking for some direction with this.

Thank you.

Disregard this post issue has been resolved.

Had GM scan the truck and they displayed a bad right rear wheel speed sensor. Call me stupid but was unaware that EFI live scanned just the ECM/TCM, and not the BCM.

EFILive has an option to read DTC's from all modules seen on the CAN LAN.

In scantool, go Edit->Properties->Advanced and checkmark Check/Clear DTC's for all modules.

It looks like that box is already checked in my Scantool...
