FCA 12+8 Universal OBD Adapter

When diagnostic tools encounter modern vehicles from the FCA Group (Chrysler, Dodge, Jeep, Fiat, Alfa Romeo) built from 2018 onward, they face a barrier known as the SGM / SGW (Security Gateway Module).

The SGW blocks aftermarket diagnostic scanners from executing commands over the OBD2 port—meaning you can read fault codes, but you cannot clear codes, perform adaptations, run bi-directional component tests, or program modules/keys.

The Autel FCA 12+8 Universal Adapter physically bypasses this hardware firewall by plugging directly into the factory wiring harness behind the gateway module.
