FCA Fiat Chrysler 12+8 Security Gateway Adapter Cable

The FCA 12+8 adapter cable is designed for Fiat Chrysler Automobiles vehicles where the Security Gateway (SGW) restricts diagnostic and programming functions through the standard OBD connection.

The adapter connects to the vehicle's 12-pin and 8-pin connectors, allowing a compatible diagnostic or key programming device to communicate directly with the vehicle's CAN network past the Security Gateway module. This enables supported diagnostic, service, programming, and key programming functions that may otherwise be restricted by the SGW system.

The cable is suitable for use with various compatible diagnostic and key programming devices.

Features

• FCA 12+8 Security Gateway bypass — Enables direct communication with the vehicle's CAN network past the Security Gateway module.
• 12+8-pin connection — Connects directly to the vehicle's 12-pin and 8-pin SGW connectors.
• Diagnostic functions — Enables functions such as reading and clearing fault codes, active tests, service functions, and special functions with a compatible device, depending on vehicle support.
• Key programming — Suitable for immobilizer and key programming functions on supported FCA vehicles.
• Programming and coding — Enables programming, adaptation, and coding functions that may otherwise be restricted by the SGW when used with a compatible diagnostic device.
• Plug-and-play connection — No wire cutting or permanent modifications to the vehicle's electrical system are required.
• Multi-brand tool compatibility — Suitable for use with various diagnostic and key programming devices that support FCA 12+8 connections.

Vehicle support

Depending on vehicle and model year, the adapter is suitable for FCA / Stellantis vehicles equipped with a Security Gateway system, including:

• Chrysler
• Dodge
• Jeep
• Fiat
• Alfa Romeo

The 12+8 Security Gateway connection is used especially on many 2018 and newer vehicles.

Applications

With a compatible diagnostic or key programming device, the adapter can be used for functions such as:

• Reading and clearing fault codes
• Active tests
• Service and special functions
• ECU coding and adaptations
• Immobilizer functions
• Key programming

Available functions depend on the vehicle and the diagnostic or key programming device being used.

Please note

• The adapter is not a standalone diagnostic or key programming device.
• The cable is required on vehicles where the Security Gateway restricts the necessary diagnostic or programming functions.
• The location of the SGW connectors may vary depending on the vehicle model and model year.
• The cable itself does not add new functions to the diagnostic device, but enables access to vehicle systems past the Security Gateway.
• Check vehicle- and model-year-specific compatibility in the latest software of the diagnostic or key programming device before starting the procedure.
