The Chrysler 12+8 Adaptor is a specialized bypass cable required for diagnosing and programming 2018 and newer FCA vehicles (Chrysler, Dodge, Jeep, Fiat, and Alfa Romeo). Newer FCA models are equipped with a Secure Gateway Module (SGW) that prevents aftermarket scan tools from performing active tests or clearing fault codes through the standard OBDII port. This adaptor allows your Autel MaxiIM IM508 or IM608 PRO to bypass the SGW for full system access.

Essential Functions & Capabilities

• Full Diagnostic Access: Enables the ability to read and clear DTCs, view live data, and perform active tests that are otherwise blocked by the SGW.

• Advanced Maintenance: Necessary for performing essential service resets, including Oil Reset, EPB, and SAS calibrations.

• IMMO & Key Programming: Required for all key programming and immobilizer part replacement on supported 2018+ FCA vehicles.

• Active Tests: Allows the technician to command vehicle components (like fuel pumps or injectors) for precise troubleshooting.

Vehicle & Tool Compatibility

• Supported Models: Works on 95% of 2018+ FCA vehicles including Jeep Renegade/Compass, Chrysler Pacifica, Dodge Challenger/Charger, and Alfa Romeo Giulia.

• Autel Integration: Fully compatible with the MaxiIM IM608 PRO, IM508, MaxiSYS Ultra, MS919, and MS909 series.

• Protocol Support: Specifically designed to handle the secure communication protocols used by modern Fiat Chrysler architectures.
