What is the Secure Gateway Module?
Many late-model FCA / Stellantis vehicles use a Secure Gateway Module, or SGW, to help protect the vehicle network from unauthorized access. Read-only diagnostics may still be available, but certain secured functions require authentication before the vehicle allows the command to proceed.
Secure Vehicle Network
The SGW works as a protected access point between the diagnostic connector and the vehicle communication network.
Authenticated User + Tool
AutoAuth verifies the technician, shop account, registered tool, and vehicle access request.
Advanced Functions
Once unlocked, supported diagnostic functions can continue through the iSCAN workflow.
Functions That May Require SGW Unlock
- Clearing diagnostic trouble codes
- Bi-directional controls
- Actuator tests
- Relearns and calibrations
- Adjustments and special functions
- Certain secured service functions
