YOUCANIC FCA 12+8 Adapter for Chrysler Dodge Secure Gateway Module Bypass work on Autel Launch Topdon

The YOUCANIC 12+8 Adapter is a must-have accessory for automotive professionals and DIYers who need full diagnostic capabilities on late-model FCA  vehicles (see list below).

 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 (and other scan tools) 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

• Maserati
  

• Alfa Romeo

📌 Common affected models include: Grand Cherokee, Wrangler, Charger, Challenger, Pacifica, 300, RAM 1500+, and more.

🔒 What is a Security Gateway Module (SGM)?

Starting in 2018, FCA began installing SGMs in most of their vehicles as a cybersecurity measure. While it protects the vehicle network, it also blocks aftermarket scan tools from sending commands or performing service functions — unless bypassed.

Estimated SGM Implementation by Model Year:

• 2017: ~20% of vehicles

• 2018: ~50% of vehicles

• 2019: ~90% of vehicles

• 2020+: ~100% of vehicles

🔌 How the Adapter Works:

• Connects to the YOUCANIC Full System Scanner (UCAN-II-C )

• Plugs directly into the vehicle’s 12+8 diagnostic port

• Bypasses the SGM for full access to all vehicle modules, including:

  • ABS

  • Airbag

  • Transmission

  • Body control module

  • Climate control

  • Steering and more

🔍 SGM Location:

The Security Gateway Module is typically located in:

• Behind the glove box

• Passenger side kick panel

• Behind the infotainment/radio unit

⚠️ Important Compatibility Note:

This adapter is only for verified YOUCANIC scanner owners.
If you purchase this adapter without owning a YOUCANIC full system scanner, your order will be canceled.

Key Clarifications

• 2017 and earlier FCA vehicles generally do not have SGW.

• 2018 model year onward: SGW became the standard across nearly every FCA/Stellantis brand, though some overlap years (like Ram DS “Classic” trucks) had mixed configurations.

• Even commercial and fleet models (ProMaster, ProMaster City) eventually received SGW after 2019.
