Understanding and customizing your vehicle’s Daytime Running Lights (DRLs) can significantly enhance its functionality and aesthetics. For RAM truck owners, achieving precise control over DRL settings is possible using advanced OBDII reader tools like AlfaOBD. This guide delves into how you can leverage an Obdii Reader Target, specifically AlfaOBD, to tailor your RAM truck’s DRL and accent light configurations, offering a superior level of customization compared to basic scan tools or modules like Tazer.
AlfaOBD stands out as a powerful diagnostic and customization tool, bringing you closer to dealer-level control over your vehicle’s Bus Communication Module (BCM) and other systems. For those looking to modify their Canadian DRL-equipped RAM trucks, AlfaOBD offers several pathways to adjust lighting behavior, from simple deactivation to complex reconfigurations.
Disabling DRLs Completely
If your goal is to permanently disable the DRLs on your Canadian RAM truck, AlfaOBD provides a straightforward solution. By accessing the BCM settings, you can effectively turn off the DRL function until you decide to reactivate it.
Steps to Disable DRLs:
- Connect your obdii reader target (AlfaOBD) to your RAM truck’s OBDII port.
- Establish a connection with the vehicle’s computer system using the AlfaOBD software on your compatible device (e.g., laptop, tablet, smartphone).
- Navigate to the BCM module within AlfaOBD’s interface.
- Locate the “CBC Features” menu, which houses various configurable settings.
- Find the “DRL configuration” parameter within the CBC Features.
- Set the “DRL configuration” value to “NO DRL”.
- Apply the changes using AlfaOBD to write the new setting to your truck’s BCM.

After completing these steps, your RAM truck’s DRLs will remain off. To reinstate them, you would simply need to reverse this process using AlfaOBD.
Setting Up US Market-Style DRLs with Radio Toggle
For users who prefer the flexibility to toggle DRLs on and off as needed, similar to US market RAM trucks, AlfaOBD enables this customization as well. This setup places DRL control directly within your truck’s radio settings menu.
Steps for US Market DRL Configuration:
- Connect your obdii reader target (AlfaOBD) to your RAM truck.
- Launch AlfaOBD and connect to your vehicle.
- Access the BCM module settings.
- Within “CBC Features”, set “DRL configuration” to “OPTIONAL”.
- Navigate to “CustSetMenu 1” settings.
- Find “daytime running lights CSM Present” and set it to “YES”.
- Write these settings to your BCM using AlfaOBD.

With these adjustments, a new option to control DRLs will appear in your RAM truck’s radio settings, allowing you to easily turn them on or off at your convenience.
Disabling Accent Lights
While accent lights cannot be toggled on/off through standard vehicle settings, AlfaOBD provides the capability to disable them entirely. This might be desirable for users seeking a more minimalist lighting appearance or specific customization goals.
Steps to Disable Accent Lights:
- Utilize your obdii reader target (AlfaOBD) and connect to your RAM truck.
- Open AlfaOBD and establish a vehicle connection.
- Access the BCM module settings.
- Locate “CBC Extern.Light Calib.” settings.
- Find “Signature light present” and set it to “NO”.
- Apply the change via AlfaOBD to disable the accent lights.
Configuring Accent Lights as DRLs
For a unique and enhanced lighting setup, you can configure your RAM truck’s accent lights to function as DRLs. This configuration not only makes the accent lights serve as daytime running lights but also allows them to operate at a brighter intensity than their factory accent light setting. Moreover, this setup ensures that only the accent light strips illuminate as DRLs (upper and lower LED strips), with no other lights activated during daytime running.
Steps to Configure Accent Lights as DRLs:
- Connect your obdii reader target, AlfaOBD, to your RAM truck’s OBDII port.
- Connect with your vehicle using AlfaOBD.
- Access the BCM module.
- Modify the following settings within AlfaOBD:
- CBC Features DRL Configuration: OPTIONAL
- CBC Features DRL Lamp Location: DEDICATED
- CBC Features DRL Dropout Enabled: YES
- CBC Extern.Light Calib. Signature Light Present: NO
- CBC Extern.Light Calib. Left Side DRL Voltage Target: 7.4 (adjustable for brightness)
- CBC Extern.Light Calib. Right Side DRL Voltage Target: 7.4 (adjustable for brightness)
- CustSetMenu 1 daytime running lights CSM Present: YES
- Write all these settings to your truck’s BCM using AlfaOBD.

These settings will achieve the following:
- Accent lights (upper and lower LED strips) will function as DRLs.
- No other lights will be on during daytime running.
- DRLs will activate only when the vehicle is in gear.
- Accent light DRLs will be brighter than factory accent lights due to the increased voltage target (7.4V, adjustable for further brightness).
- The DRL on the turn signal side will “drop out” when the turn signal is active.
- You will have the ability to toggle these accent light DRLs on/off via the radio settings menu.
Conclusion
AlfaOBD, as a targeted obdii reader target, empowers RAM truck owners with extensive control over their vehicle’s lighting configurations. Whether you aim to disable DRLs, enable US market-style toggling, disable accent lights, or reconfigure accent lights as enhanced DRLs, AlfaOBD provides the necessary tools to achieve these customizations. By carefully adjusting the BCM settings outlined in this guide, you can tailor your RAM truck’s lighting to match your preferences and needs, going beyond the limitations of simpler OBDII devices and achieving a truly personalized driving experience. Remember to always exercise caution and double-check settings when using advanced diagnostic tools to modify your vehicle’s systems.
