DESCRIPTION

Product Overview

Starting with many 2018+ Ram pickup trucks, FCA introduced a Security Gateway Module that limits unauthorized communication and certain programming functions through the factory OBD2 port. These restrictions can prevent some aftermarket diagnostic and tuning tools from accessing advanced vehicle functions.
The HD Security Gateway Bypass Cable provides an alternate communication path through the factory CAN network, allowing compatible aftermarket tools to communicate with supported vehicle modules.
Designed for tuning, diagnostics, and vehicle configuration applications, this bypass cable helps restore access to supported functions without modifying the factory ECM or vehicle wiring.
