12+8 Adapter for FCA Chrysler Dodge Secure Gateway Module Bypass

The YOUCANIC 12+8 Adapter is a must-have accessory for automotive professionals and DIYers who need full diagnostic capabilities on late-model FCA (Fiat Chrysler Automobiles) vehicles. This adapter is specifically designed to bypass the factory-installed Security Gateway Module (SGM) — a system that blocks most aftermarket scan tools from performing advanced diagnostics beyond basic code reading and live data. Without this adapter or AutoAuth credentials, scan tools attempting to communicate with FCA vehicles equipped with an SGM will display errors such as: “Device unable to communicate with the control unit.” This adapter allows your YOUCANIC Full System Scanner to seamlessly access all modules for bi-directional control, active tests, resets, adaptations, and advanced diagnostics — just like the dealership scan tools. ✅ Compatible FCA Brands: Chrysler Dodge Jeep RAM Fiat Alfa Romeo 📌 Common affected models include: Grand Cherokee, Wrangler, Charger, Challenger, Pac
