Fca Bypass Cable Chrysler 12+8 OBD2 Pin 16 Female Main Test Programming Adapter for Jeep RAM Dodge Support Scanner Autel MS906 DS808 MS905 MS906BT MS906TS MS908 MS908S PRO MS909 MS919 Elite

The 12+8 FCA Bypass Cable is a specialized diagnostic adapter designed to circumvent the Security Gateway Module (SGW) found in most 2018 and newer Fiat Chrysler Automobiles (FCA).
Starting in 2018, FCA (now part of Stellantis) implemented the SGW as a firewall to prevent unauthorized access and potential hacking of the vehicle’s internal networks via the standard OBD2 port. While standard OBD2 scanners can still “read” basic data through the normal port, the SGW blocks them from “writing” data or performing advanced functions.
Key Functions
The bypass cable allows aftermarket diagnostic tools (such as those from Autel, Launch, or Topdon) to perform “write” operations that the gateway otherwise blocks:
Clearing Fault Codes: Bypassing the gateway is necessary to clear many specific diagnostic trouble codes (DTCs).
Active Tests & Bi-directional Control: Necessary for testing components like fuel pumps, cooling fans, or wipers.
Maintenance Resets: Includes oil life resets and TPMS (tire pressure) relearns.
Module Programming & Adaptation: Essential for key programming, ECU coding, and ADAS calibrations.
Compatible Vehicles
This cable is generally required for 2018+ models across these brands, though some models (like the RAM ProMaster) required it as early as 2013:
Jeep: Wrangler (JL), Grand Cherokee, Renegade, Compass, Cherokee.
Dodge: RAM (1500/2500/3500), Durango, Charger, Challenger, Journey.
Chrysler: Pacifica, 300.
Fiat / Alfa Romeo: 500x, Giulia, Stelvio.
How to Use It
The cable works by physically “unplugging” the gateway and “jumping” the connection directly to your scanner:
Locate the SGW: It is often tucked behind the radio, under the dashboard, or near the glove box.
Unplug the Gateway: Disconnect the factory 12-pin and 8-pin connectors from the module.
Connect the Bypass: Plug those two factory connectors into the matching 12-pin and 8-pin ends of the bypass cable.
Plug in Your Scanner: Connect the other end of the bypass cable (a standard 16-pin OBD2 female port) to your diagnostic tool or Bluetooth adapter.

Note: Some modern scanners (like newer Autel or Launch tablets) can bypass the gateway digitally through an AutoAuth subscription, which avoids the need for this physical cable by using a licensed internet connection.

A 12+8 FCA bypass cable is a specialized adapter used to bypass the Security Gateway Module (SGM/SGW) found in most 2018 and newer Fiat Chrysler Automobiles (FCA) vehicles, including Chrysler, Dodge, Jeep, RAM, Fiat, and Alfa Romeo. This module acts as a firewall that restricts aftermarket scan tools to “read-only” access (viewing data and codes but not clearing them or performing active tests).
Supported Scan Tools
The cable is designed to be universal for most professional-grade and DIY aftermarket diagnostic tools. While some cables are brand-specific, most high-quality 12+8 adapters work with:
Autel Scanners: Full support for the MaxiSys Series (MS906, MS908, Elite, Ultra), MaxiCheck/MaxiCOM (MK808, MX808, MP808), and IM series (IM508, IM608).
Launch Tools: Compatible with Launch X431 V, X431 V+, Pro Elite, and CRP series (CRP919E, CRP919X).
XTOOL: Supports the D7, D8, D9, IP616, and A80 series (Note: XTOOL often requires their specific brand of cable).
OBDSTAR: Compatible with X300 DP Plus and other key programming devices.
Thinkcar: Supported via specialized Thinkcar adapters.
Smartphone Apps: Works with wireless OBD2 adapters (like OBDLink MX+) and apps like JScan OBD and AlfaOBD.
Lonsdor: Specifically the K518 Pro and K518ISE for key programming.
Key Capabilities Unlocked
Once connected, these tools can perform advanced functions that are otherwise blocked:
Active Tests/Bi-directional Control: Activating components like fans, fuel pumps, or wipers.
Writing Data: Clearing diagnostic trouble codes (DTCs) and performing ECU coding or adaptations.
Maintenance Resets: TPMS OBDII relearns, oil life resets, and ADAS calibrations.
Key Programming: Adding or replacing vehicle keys.
Note: Some manufacturers (like Autel) also offer a digital bypass via an AutoAuth subscription ($50/year), which removes the need to physically crawl under the dash to install the cable for certain tools.
