DESCRIPTION
Product Overview
- Starting with many 2018+ Ram 6.7L Cummins trucks, FCA introduced a SGW that limits certain aftermarket communication, programming, and configuration functions through the factory OBD2 port. These restrictions can prevent some tuning and diagnostic tools from accessing advanced vehicle functions.
- The Bypass Cable provides an alternate communication path through the vehicle CAN network, bypassing SGW communication restrictions and allowing compatible aftermarket tools to communicate with supported vehicle modules.
- It restores access for supported tuning, diagnostics, and configuration functions while keeping the factory OBD2 system available for normal vehicle operation and everyday use.
Key Features
- Durable Automotive Construction: Built with high-temperature wire sleeving and vibration-resistant materials for reliable long-term performance.
- Maintains OEM Functionality: Keeps the factory OBD2 port available for diagnostics, code scanning, inspections where applicable, and supported tuning features.
- Enables Supported Tuning Access: Bypasses factory Security Gateway Module restrictions, allowing compatible tuning platforms such as EFILive, EZ LYNK, and MM3 to communicate with supported vehicle modules.
- Supports Vehicle Configuration Changes: Works with compatible tools like AlfaOBD and JScan for supported functions including tire size adjustment, gear ratio updates, remote start configuration, and accessory programming.
FAQ
Q: What does a Cummins SGW bypass cable do?
A: The SGW bypass cable bypasses factory Security Gateway Module communication restrictions, allowing compatible tuning and diagnostic tools to communicate with supported vehicle modules.
Q: Does this cable add horsepower or improve performance?
A: No. The bypass cable does not increase power or modify ECM calibration. It only restores communication access for compatible tuning and diagnostic tools.
Q: Why do 2018+ Ram Cummins trucks need an SGW bypass?
A: The factory Security Gateway Module limits certain aftermarket communication functions through the OBD2 port. A bypass cable allows supported tools to access advanced diagnostics, programming, and configuration features.
Q: Can I leave the bypass cable installed permanently?
A: Yes. It can be installed behind the dash and left connected for regular use, or removed and reused when needed.
Q: Is this required for EFILive, EZ LYNK, or MM3 tuning?
A: Many aftermarket tuning tools require SGW access to perform certain functions on 2018+ Ram trucks. Compatibility depends on the specific tool and vehicle configuration.
