FITMENT

  • 2018-2024 6.7L Ram Cummins 2500 3500 Turbo Diesel.

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.

Works on 2024 — Stellantis tried but they cannot stop us

2024 Ram 2500. The newest model year with all the connected services and over-the-air updates. This bypass cable still works because FCA has not changed the physical CAN bus connector layout even on the 2024s. The green connectors are in the same spot behind the radio. If you have a 2024 and you are worried the SGW has been updated — it has not. This cable works.

No guesswork — the connectors only go one way

2021 Ram 3500 dually. The two green CAN bus connectors behind the radio are keyed differently so you cannot plug them in wrong. The 12-pin and 8-pin are different sizes. The bypass cable is clearly labeled and the pins are properly crimped. Plugged in, flashed my EZ Lynk delete tune, unplugged the cable, and the truck fired right up with no codes. Took longer to find the connectors behind the dash than to actually use the cable.

Simple, works, and costs half the passthru harness

2020 Ram 2500. If you just need to flash a tune and do occasional diagnostics, this basic SGW bypass cable is all you need. Plug the green connectors behind the HVAC panel, flash your tune, and unplug it. No need to spend double on a passthru harness that stays installed permanently unless you are tuning constantly. Worked perfectly with HP Tuners on a 2020 Cummins.
