2018 MODELS WARNING: Some 2018 Fiat group vehicles have a "security gateway" module (SGW). The SGW module blocks any diagnostic tool from executing commands on the vehicle (like actuators, procedures and even clearing of DTCs). It is not possible to unlock the SGW module with Multiecuscan. The only diagnostic tool that can unlock full access to the affected vehicles is the factory tool. Another option is to physically connect the diagnostic tool to CAN lines behind SGW module. The 2018 models with confirmed presence of SGW are: 500X/Renegade, 500L MCA, Doblo, Giulia/Stelvio. The module is also present in some late 2017 vehicles. You can run the SCAN function (which is also available in the FREE version of Multiecuscan) to check if your vehicle has SGW module.
