Autel Chrysler Fiat 12+8 OBD cable

The 12‑8 Adapter bypasses Chrysler’s Security Gateway Module (SGM), which otherwise restricts aftermarket scanners to DTC reading and basic data. It connects to the Autel MaxiSYS VCI and restores full communications with ECUs.

Common SGM locations: passenger kick‑panel, near the glovebox, or behind the radio.
Adapter required increasingly by model year — ~20% of 2017, 50% of 2018, 90% of 2019 and virtually all 2020+ Chrysler vehicles.

• Purpose: Bypasses Chrysler’s Security Gateway Module (SGM), which blocks aftermarket scan tools from performing full diagnostics. Enables bidirectional controls on 2018+ Chrysler, Dodge, Jeep, Fiat, and Alfa vehicles.

• Compatible Scanners: Works with Autel MaxiSys series, including MS906, MS906BT, MS906TS, MS908, MS908S, MS908S PRO, and Maxisys Elite.

• SGM Location: Typically found near the passenger-side kick panel, behind the radio, or near the glove box.
