All 2018+ FCA(Stellantis) vehicles are built with a Security Gateway Module (SGW) that prevents access to the vehicle from the OBD2 port by anything other than the dealer diagnostic tools.
Simply locate and unplug the SGW module, plug the SGW Bypass block in its place. The OBD2 port will then have full access for use by aftermarket devices such as Z Automotive’s Tazer or BurnBox, tuning tools, and code readers.
