I just installed an AEM obd2 wideband 30-0333. When I plug the mpvi2 into the passthrough my stabilitrack and traction control lights come on and it wont scan, in vcm scanner. If I disconnect the aem passthrough the scanner works. I've tried the different bit identifiers and bitrates on the wideband, but it still does the same. Has anyone had this problem? The ecu address and pid value are set to default. This is installed in a 2012 CTS V.

If you have the ECU using the same address as another ECU on the car it will confuse things. Keep changing the ECU address until it works? HPT will find the address by repolling.
Aside from having an obd2 scanner, it is also helpful to have the best multimeter https://totalguide.org/best-multimeter/. The device is used to compute voltage, current, resistance, and frequency among other uses, this tool has helped me a lot as well.
as hand as the OBD2/CAN version is, I find a USB splitter and using the serial out on the AEM to a DB9->USB adapter to be the most reliable. It pretty much ALWAYS works. Granted you cannot do it via bluetooth (I am actually working on a solution to that though), it works allll the frikkin time.
