** Important - 2018+ model year coverage **
Please note - many Fiat group vehicles from the 2018 model year onwards (sold since mid-2017) , have a
"
Security GateWay" Module (
SGW) fitted.
The SGW module limits diagnostic communication to
read-only access, unless the tool can obtain a session-specific
access code from Fiat group's servers (which requires an expensive subscription).
This limitation blocks tools from executing commands on the vehicle (e.g. actuations, procedures
and even clearing of DTCs).
First generation SGW modules can generally be simply bypassed, by unplugging the SGW from the car, and connecting an
SGW Bypass Adaptor in its place.
However, a second generation SGW is now being fitted to some models (e.g. Fiat 500e 2020-on, Fiat Ducato x290 MCA approx. 2022-on). The 2nd gen units are integrated into the Body Control Module, and so cannot be practically bypassed. See our
SGW help article for more information.
