The FCA 12+8-pin SGW Adapter Cable connects the internal wiring of the Security Gateway Module (SGW) in vehicles from the Fiat Chrysler Automobiles group to a standard 16-pin OBD2 interface. This Adapter features a male 12-pin and a male 8-pin connector on the vehicle side, which connect directly to the vehicle's contrast connectors, replacing the connection to the security module.
This cable allows the physical bypass of the SGW security, enabling direct communication with the vehicle's CAN bus networks. This grants the diagnostic equipment the necessary write permissions for advanced functions such as clearing fault codes, performing actuator tests, and recalibrating systems, which are often blocked via the standard diagnostic port on models from 2018 onwards.
ADVANTAGES
ATTENTION POINTS
Applications and functionalities
This Adapter Cable is used when the standard OBD2 port provides limited access to the vehicle systems due to the presence of a Security Gateway.

- Clear fault codes: Ability to remove permanent and temporary DTCs from various modules.
- Active component tests: Control actuators such as fans, injectors, and ABS pumps.
- Service reset: Perform oil reset and maintenance interval resets that require write access.
