AUGOCOM 12+8-Pin SGW/SGM Bypass Cable for Chrysler Dodge Jeep 2018+ — Restores Full Diagnostic Access

The AUGOCOM 12+8 pin bypass cable lets technicians and vehicle owners bypass the FCA Security Gateway (SGW/SGM) on 2018+ Chrysler, Dodge and Jeep models to restore full diagnostic access for compatible tools.

Modern FCA (Chrysler Fiat Automobiles) vehicles introduced a Security Gateway Module (SGM or SGW) that restricts third-party diagnostic tools from accessing vehicle networks. This AUGOCOM bypass harness provides a simple hardware workaround for 2018 and newer FCA platforms, enabling many aftermarket and professional scan tools to reach vehicle modules for live data, fault reading and VIN identification without reprogramming the vehicle.

How does this bypass cable work with the SGW/SGM?

The cable replaces the factory SGW connection by routing the 12-pin and 8-pin vehicle ports through a controlled pass-through assembly. It does not reflash or modify vehicle software — it simply completes the communication path so compatible diagnostic tools can exchange messages with vehicle modules.

• Connects to the vehicle's original 12-pin and 8-pin SGW/SGM connectors
• Routes signals to your diagnostic tool while isolating the factory gateway
• No vehicle programming required; pure hardware bypass

Which vehicles and tools are supported by this cable?

The harness is designed for FCA platforms from 2018 onward and covers a wide range of Jeep, Dodge and Chrysler models. Compatibility depends on your diagnostic tool: basic OBD-II functions work broadly, while advanced module programming or manufacturer-level services require tools that explicitly support SGW bypass operation.

• Compatible models include Jeep Renegade, Compass, Cherokee, Wrangler, Grand Cherokee
• Works with Dodge Ram, Durango, Journey, Charger, Challenger
• Supports Chrysler Pacifica and 300 for 2018+ VINs
• Advanced functions depend on your scan tool’s capabilities

What installation steps are required and how simple is it?

Installation follows a clear three-step plug-and-play routine that most technicians or experienced DIYers can complete in minutes. No special tools, soldering or ECU programming are required — just unplug the SGW connectors, plug in the AUGOCOM harness, then attach your diagnostic device.

• Locate and unplug the vehicle’s 12-pin and 8-pin SGW/SGM connectors
• Insert the AUGOCOM 12+8 pin bypass cable into the vehicle ports
• Connect your diagnostic tool to the harness and power the vehicle’s OBD port

What limitations should I expect using non-OEM diagnostic tools?

When using standard aftermarket OBD2 scanners, some service-level functions may be restricted. Most non-OEM tools will reliably read trouble codes, show live data streams and retrieve VIN details, but manufacturer-specific programming, module flashing or advanced resets may not be available without OEM-level software or tool support.

• Guaranteed: read fault codes, live data viewing, VIN identification
• Potentially limited: module programming, key programming, advanced dealer services
• Confirm compatibility of your diagnostic device for full functionality

Who is this for? The AUGOCOM 12+8 pin SGW/SGM bypass cable is ideal for independent mechanics, fleet technicians and savvy vehicle owners who need reliable diagnostic access to 2018+ FCA platforms without dealer-only restrictions. If you use aftermarket scan tools for troubleshooting, troubleshooting module faults, or routine fleet diagnostics, this durable, plug-and-play harness simplifies access and avoids time-consuming workaround procedures. For full dealer-level programming or security-sensitive services, pair this cable with a diagnostic tool that explicitly supports advanced FCA functions.
