The 12 8 Adapter is Autel’s bypass for Chrysler’s Security Gateway Module (SGM) which limits an aftermarket scan tool to only reading DTCs and viewing data.
Most 2018 and newer FCA vehicles include a Security Gateway Module
Expect to see this message when scanning a Chrysler with the Security Gateway Module:

Placement of the SGM varies, but it is often located in the side kick panel, passenger side near the glove box, or behind the radio.
