The Jaltest (JDC406A) is an Adapter Cable designed to establish a connection between a diagnostic device and specific vehicles from the FCA group (Fiat Chrysler Automobiles). The cable features a 12+8-pin connector for the vehicle side and a standard 16-pin OBD2 connection for the reading device.
This Adapter is specifically developed to bypass the Security Gateway Module (SGW), which is present in newer FCA vehicles. The SGW functions as a firewall and restricts access via the OBD2 port to data reading only. By using this cable, a direct connection to the vehicle's CAN bus is enabled, allowing extended diagnostic functions such as clearing fault codes, performing active tests, and executing service procedures.
Application and functionality:
This Adapter Cable makes it possible to bypass the Security Gateway Module (SGW) in FCA vehicles, thereby gaining full diagnostic access.
- SGW bypass: Enables a direct connection to the vehicle's diagnostic network, bypassing the SGW.
- Extended diagnosis: Unlocks the ability to clear fault codes, perform service functions, and carry out calibrations.
- Active tests: Allows performing actuator tests and component controls, functions blocked by the SGW.
- Universal compatibility: The 16-pin OBD2 connection is compatible with most modern diagnostic devices that support FCA diagnostics.
Compatible vehicles and applications:
This Adapter is intended for vehicles from the FCA group equipped with a Security Gateway Module (SGW) from approximately model year 2018 onwards. The location of the SGW may vary by model.
