DESCRIPTION
Product Overview
- Starting with many 2018+ Ram trucks, FCA introduced a SGW that limits unauthorized access to vehicle communication networks. While factory scan tools can still access basic vehicle information, some aftermarket diagnostic, programming, and customization functions may be restricted.
- The SGW Security Gateway Bypass Harness provides a direct connection solution for compatible aftermarket tools by bypassing the factory communication restriction. It allows supported diagnostic, programming, and accessory configuration functions without modifying the factory ECM hardware.
Key Features
- Durable Automotive Construction: Built with heat-resistant wiring protection and high-impact connectors for reliable performance in harsh vehicle environments.
- Maintains OBD2 Diagnostic Access: Supports code reading/clearing, live data monitoring, and advanced diagnostics through compatible OBD2 tools.
- Unlocks FCA Security Gateway: Access Bypasses factory communication restrictions, allowing compatible diagnostic and tuning tools to access supported vehicle functions.
- Supports Aftermarket Programming Features: Enables supported vehicle configuration changes such as tire size adjustments, gear ratio settings, remote start setup, and accessory installations.
FAQ
Q: What does an SGW bypass harness do?
A: The SGW bypass harness bypasses the factory Security Gateway communication restriction, allowing compatible aftermarket diagnostic and programming tools to communicate with supported vehicle modules.
Q: Why do I need an SGW bypass on my 2018+ Ram?
A: The factory SGW module limits certain aftermarket tool functions. A bypass harness allows supported tools to access vehicle modules for diagnostics, programming, and configuration changes.
Q: Will this allow me to flash custom tunes?
A: It allows compatible tuning tools to communicate with supported vehicle systems. Actual tuning capability depends on your tuner, software, and available calibration files.
Q: Is this required for EZ LYNK, EFILive, MM3, or AlfaOBD?
A: Yes. Starting in 2018, Ram SGW acts as a digital firewall that blocks write commands; without this bypass harness, devices like EZ LYNK, EFILive, MM3, and AlfaOBD cannot flash custom tunes or modify vehicle settings.
