How to Reset Battery Management System (BMS) in F-150?

The battery management system (BMS) plays a crucial role in ensuring optimal performance and longevity of the battery in your Ford F-150. It is responsible for monitoring the battery’s health, regulating its charging and discharging cycles, and safeguarding against potential issues. 

Over time, however, the BMS may encounter glitches or discrepancies, resulting in diminished battery performance or even triggering warning indicators on your vehicle’s dashboard.

In this article, we will guide you through a step-by-step process to reset the Battery Management System (BMS) in your F-150. 

Resetting Battery Management System (BMS) in F-150: Key Takeaways 

• Step 1. Disconnecting the Battery
• Step 2. Activating the Headlights
• Step 3. Cycling the Lights
• Step 4. Engaging the Brake Pedal
• Step 5. Observing the Battery Light Signal
• Step 6. Restarting the Vehicle

Step-By-Step Guide: Resetting Battery Management System in F-150

Follow these next steps and you will reset your battery management system in F-150 in no time. 

Step 1. Disconnecting the Battery

Access the car’s battery by opening the hood to initiate the process. Locate the negative connector and disconnect it from the battery.

Step 2. Activating the Headlights

Proceed to the driver’s seat and insert the key into the ignition without turning it to start the engine. Switch on the headlights by turning them to the “on” position.

Ensure that you aim the headlights away from people to avoid blinding them, and avoid placing the headlights in the auto position.

Step 3. Cycling the Lights

Repeatedly pull the headlight knob toward the steering wheel five times. This action should be performed within 10 seconds of completing step one. The display screen will indicate the headlights blinking five times.

Step 4. Engaging the Brake Pedal

Immediately after completing step three, repeat the process with the brake pedal.

Press the brake pedal down toward the floor three times consecutively using your foot. Each time, fully release the brake pedal before pressing it down again.

Ensuring the correct execution of this step is crucial, as the vehicle needs to receive the code for the BMS reset to be effective. Perform this step immediately after completing step two.

Step 5. Observing the Battery Light Signal

After completing steps two and three, wait for an indication of success.

If you followed the previous steps correctly, you should observe a red battery icon on the display. The battery icon flashes a few times, signaling the reset is concluding.

Be patient, as it may take more than 10 seconds for the flashing to occur. Repeat the process if the flashing doesn’t appear after a few minutes.

Step 6. Restarting the Vehicle

The final step is to restart the vehicle once you have completed the preceding steps.

Remove the key from the ignition and reinsert it. Turn the key to power on the accessories, and then turn it all the way to start the vehicle fully.

If the battery icon disappears from the display screen and there are no messages regarding the BMS, it indicates a successful system reset.

What Is Battery Management System (BMS)? 

The Ford Battery Management System (BMS) is a sophisticated technology integrated into Ford vehicles, including models like the F-150. 

Its primary function is to monitor and regulate the charging and discharging of the vehicle’s battery, ensuring optimal performance and longevity.
