    Aem wideband obd2 passthrough not working with mpvi2

    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.

    I have not had this problem. Is it set for 500k, and 11bit? ECU Address 7E7? That's what mine is set for, 2010 E38 Camaro. 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.
