** Important - 2018+ model year coverage: **
Please note - some vehicles from the 2018 model year onwards (sold since mid-2017) , will have a
"
Security GateWay" Module (
SGW).
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).
However, the current generation of SGW can be bypassed, by unplugging the SGW from the car, and connecting an
SGW Bypass Adaptor (available separately) in its place.
Vehicles known to be affected so far include MY2018 500X/Renegade, 500L MCA, Doblo, Giulia/Stelvio.
