For enthusiasts and everyday drivers alike, the ability to tap into your vehicle’s hidden settings and diagnostics is incredibly appealing. If you own a 2017 Ram 1500, you’re in luck! Thanks to its unique onboard computer system, accessing and modifying various features via the OBD2 port is surprisingly straightforward. Forget expensive dealership visits for simple tweaks; with the right tools and knowledge, you can perform a range of impressive OBD2 changes right in your driveway. This guide will explore the best OBD2 modifications you can make to your 2017 Ram 1500, unlocking a new level of personalization and control over your truck.
The Unique Advantage of FCA Vehicles: Why Your Ram 1500 is Different
Many vehicle owners are familiar with OBD2 scanners for reading basic engine codes. However, the capabilities of the OBD2 port can extend far beyond simple diagnostics. Typically, accessing advanced features like body control module settings or transmission parameters requires specialized, costly equipment and manufacturer-specific software. This is where FCA (Fiat Chrysler Automobiles), now Stellantis, vehicles like your 2017 Ram 1500 stand out.
Vehicles from FCA, including Dodge, Chrysler, and Jeep, produced over the last decade or so, often utilize a system centered around the TIPM (Totally Integrated Power Module). While the TIPM has gained notoriety for some reliability issues, its design offers a significant benefit for OBD2 access. Unlike many other manufacturers that segregate vehicle systems across different communication networks, the TIPM acts as a central communication hub. This means that virtually every module in your 2017 Ram 1500 is accessible through the OBD2 connector using standard CAN (Controller Area Network) protocols.
An OBD2 port, typically located under the dashboard on the driver’s side, provides access to your vehicle’s computer systems for diagnostics and customization.
This centralized communication architecture is a game-changer. On most other brands like GM, Ford, Honda, or Toyota, generic OBD2 scanners are limited to powertrain-related information. Want to read ABS codes? Airbag faults? Body control module data? Usually, you’re out of luck with a basic scanner. However, with your 2017 Ram 1500 and its TIPM system, you can delve into all these areas and more using relatively inexpensive OBD2 tools.
Top OBD2 Changes to Explore on Your 2017 Ram 1500
So, what exactly can you do with this enhanced OBD2 access on your 2017 Ram 1500? The possibilities are extensive, ranging from simple convenience features to more advanced system adjustments. Here are some of the most popular and impactful OBD2 changes you can consider:
1. Tire Pressure Monitoring System (TPMS) Adjustments
For many Ram 1500 owners, especially those who swap between summer and winter tires or frequently off-road, the TPMS can be a source of frustration. The system is designed to alert you to low tire pressure, which is crucial for safety. However, if you run different tire pressures for off-roading or don’t use sensors in winter tires, the constant warning light can become annoying.

Using OBD2, you can often disable the TPMS system altogether or adjust pressure thresholds to better suit your needs. This can eliminate warning lights without affecting the actual functionality of the system when you want it active. Keep in mind local regulations regarding TPMS, but for off-road or track use, this can be a valuable customization.
2. Lighting and Visibility Enhancements
The lighting systems in modern vehicles are controlled by sophisticated electronic modules, and your 2017 Ram 1500 is no exception. OBD2 access allows you to tweak various lighting parameters, potentially including:
- Daytime Running Lights (DRL): Customize DRL behavior, potentially enabling or disabling them, or changing which lights function as DRLs (e.g., low beams, fog lights, or dedicated LED strips if equipped).
- Fog Light Control: Modify fog light operation, such as enabling them to stay on with high beams (depending on local laws).
- Courtesy Lighting: Adjust the duration of interior lights staying on after you exit the vehicle.
- Headlamp Settings: In some cases, you might be able to adjust headlamp sensitivity or delay settings.

These lighting adjustments can enhance both the appearance and functionality of your Ram 1500, improving visibility and personalization.
3. Comfort and Convenience Features
Beyond safety and aesthetics, OBD2 can unlock a range of comfort and convenience features. Depending on your Ram 1500’s specific options and modules, you might be able to control:
- Remote Start Options: Modify remote start behavior, such as run time or climate control settings upon remote start.
- Power Window Operation: Potentially enable features like “global windows” where all windows can be opened or closed simultaneously with the key fob.
- Door Lock/Unlock Behavior: Customize auto-locking/unlocking features based on speed or gear selection.
- Chime and Alert Volumes: Adjust the volume of various warning chimes and alerts within the vehicle.

These tweaks can personalize your driving experience and tailor your Ram 1500 to your specific preferences.
4. Diagnostic Capabilities and System Checks
Of course, the primary function of OBD2 is diagnostics. With enhanced access on your Ram 1500, you can go beyond basic engine codes and:
- Read Trouble Codes from All Modules: Access fault codes from systems like ABS, Airbags, Transmission, Body Control, HVAC, and more.
- Clear Trouble Codes: Reset warning lights after addressing issues (always diagnose the root cause first!).
- Live Data Monitoring: View real-time data streams from various sensors and modules throughout the vehicle, useful for troubleshooting and performance monitoring.
- Perform System Tests: Some advanced OBD2 tools allow you to initiate system tests, such as ABS pump cycling or individual injector tests.

Essential Tools and Software for OBD2 Modifications
To perform these OBD2 changes on your 2017 Ram 1500, you’ll need the right tools. Luckily, you don’t need expensive professional equipment. Here are the basics:
- OBD2 Adapter: You’ll need an OBD2 adapter that plugs into your Ram 1500’s OBD2 port. Popular options include:
- ELM327 Adapters: Affordable and widely compatible Bluetooth or Wi-Fi adapters.
- OBDLink Devices (e.g., OBDLink MX+, OBDLink LX): Higher quality and faster adapters, often recommended for more advanced functions.
- Software/Apps: You’ll need software or mobile apps that can communicate with your chosen OBD2 adapter and access the advanced features of your Ram 1500’s TIPM system. Options include:
- AlfaOBD (Android App & Windows Software): Specifically designed for FCA vehicles and highly recommended for advanced modifications.
- OBDLink App (for OBDLink adapters): Offers diagnostic and some customization features.
- Generic OBD2 Apps (e.g., Torque Pro, DashCommand): Can provide basic diagnostics and data logging but may have limited advanced functionality for FCA vehicles.
For most of the changes mentioned above, AlfaOBD paired with a quality OBD2 adapter like OBDLink MX+ is often considered the best combination for FCA vehicles, including your 2017 Ram 1500.
A Word of Caution and Responsible Modification
While the OBD2 capabilities of your 2017 Ram 1500 are impressive, it’s essential to proceed with caution and responsibility. Incorrect modifications can potentially lead to vehicle malfunctions or unintended consequences. Always do thorough research, understand the functions you are changing, and back up your vehicle’s original settings before making any modifications. Online forums and communities dedicated to Ram 1500 and FCA OBD2 modifications are valuable resources for learning and getting advice.
