For automotive enthusiasts and professional technicians, accessing the OBD2 port is the first step in diagnosing vehicle health and performance. If you own a 2019 RAM 1500, locating this port is crucial for running diagnostic scans. This article will guide you to the 2019 Ram 1500 Obd2 Port Location and shed light on the security gateway system that may impact your diagnostic procedures.
Understanding the OBD2 Port and Security Gateway in Modern Vehicles
The On-Board Diagnostics II (OBD2) port is a standardized interface in modern vehicles, providing access to the vehicle’s computer systems for diagnostics and monitoring. However, to combat unauthorized access and potential cyber threats, manufacturers like FCA (Fiat Chrysler Automobiles, now Stellantis) introduced the Security Gateway (SGW) module in their vehicles starting from 2018. This SGW acts as a firewall, protecting the vehicle’s network from external intrusions through the OBD2 port.
Locating the OBD2 Port on a 2019 RAM 1500
The good news for 2019 RAM 1500 owners is that the OBD2 port is situated in a readily accessible location, consistent with industry standards.
The OBD2 port in a 2019 RAM 1500 is located beneath the steering column, on the driver’s side. It’s typically found on the lower edge of the dashboard, near the pedals. You’ll usually see a trapezoid-shaped, 16-pin female connector. This standard location makes it easy to connect your OBD2 scanner or code reader for vehicle diagnostics.

The Security Gateway Challenge for 2019 RAM 1500 Diagnostics
While the OBD2 port location is standard, the 2019 RAM 1500, like other FCA vehicles from 2018 onwards, is equipped with a Security Gateway module. For the 2019-2021 RAM 1500 (new body style), the Security Gateway is located directly behind the OBD2 port itself.
This means that while you can physically connect an OBD2 scanner to the port, the SGW may restrict full communication with all vehicle modules. Depending on the scanner’s capabilities, you might be limited to basic OBD2 functions like reading generic fault codes, but advanced functions like module programming, live data streaming from all modules, and bidirectional controls might be blocked by the SGW.
Bypassing the Security Gateway for Comprehensive Diagnostics
To overcome the Security Gateway restrictions and perform in-depth diagnostics on your 2019 RAM 1500, you may need to use an SGW bypass solution. These solutions essentially allow your diagnostic tool to communicate with the vehicle’s systems without SGW interference.
Common types of SGW bypass solutions include:
-
12+8 Bypass Cables/Adapters: These adapters physically bypass the SGW by connecting directly to the diagnostic system, often utilizing a specific 12+8 pin configuration. Several brands offer these adapters, including:
- Autel FCA 12+8 SGW adapter: A popular choice for Autel scan tools, enabling SGW bypass for FCA vehicles.
- OBDSTAR 12+8 Adapter: Designed for use with OBDSTAR diagnostic equipment.
- Xhorse 12+8 adapter: Compatible with Xhorse key programming and diagnostic tools.
-
Star Connectors: These connectors offer another method to bypass the SGW, sometimes used in conjunction with specific diagnostic procedures.
It’s important to choose a bypass method and tool that is compatible with your diagnostic needs and equipment.
Beyond the OBD2 Port: Other FCA SGW Locations
While for the 2019 RAM 1500, the SGW is behind the OBD2 port, it’s worth noting that FCA placed the SGW in various locations across different models. For example, in some RAM trucks and other FCA vehicles, the SGW might be located:
- Behind the instrument cluster
- Behind the radio
- Behind the glovebox
This variation highlights the importance of consulting vehicle-specific information when dealing with SGW-related diagnostics on FCA vehicles.
Conclusion: Accessing Your 2019 RAM 1500 OBD2 Port and Navigating the SGW
Locating the OBD2 port on your 2019 RAM 1500 is straightforward – it’s under the steering column, a standard location for easy access. However, understanding the presence of the Security Gateway is crucial for effective diagnostics. If you plan to perform in-depth scans or advanced functions, be prepared to utilize an SGW bypass solution to ensure full communication with your vehicle’s systems. By understanding both the OBD2 port location and the SGW system, you can confidently approach diagnostics and maintenance on your 2019 RAM 1500.
