Many FIAT group vehicles from the 2018 model year onwards (
sold from mid-2017)
are fitted with a
Security Gateway (SGW) module.
This sits between the diagnostic socket and the rest of the diagnostic system, and prevents everything except
read-only access to the car, unless the tool can supply a session-specific security code from FIAT's servers.
Low-cost aftermarket tools such as MultiECUScan do not have access to those servers, and so can only access read-only
data on vehicles fitted with an SGW (unless you physically bypass the module).
If you have bought the package for a 2017 or newer model, do
NOT activate the software license immediately.
(Once activated, the value of the software license
cannot be refunded).
Unfortunately the multiplexed interface cannot be used by the MultiECUScan software until the license has been activated,
so we cannot use it to check for an SGW before activation. Therefore if you are unsure if your vehicle has an SGW you
activate
at your own risk.
If unsure, please
contact us with the vehicle details, and we may know more.
