Wait for the whole night or 6 to 8 hours to restore its functioning. You have to turn off the ignition switch and all the ignition components this time.
Turn on the ignition after completion of 8 hours and keep the engine turn off. Next, press the brake pedal and check the functioning of the headlights.
Using scanner tools
You can do this procedure at home or take help from the technicians. In addition, you can also take your truck to the service centers for this procedure.
Disconnect the battery’s negative terminal to cut off the power supply from all the electrical systems.
Open the truck’s hood and find the Ford BMS’s fuse box. Remove the fuse and then connect the scanner to the computer system.
Turn on the scanner screen and open the diagnostic option. You can see the reset function there and click on that icon.
Attach the negative terminal and fuse again once the resetting procedure completes.
Turning on the ignition switch
Sit inside your vehicle and ensure that all the doors and power windows are closed correctly. Use the keys and turn on the ignition.
On the screen, you can see that the battery icon will flash several times.
Press the brake pedal and simultaneously release it quickly. Then, repeat the same procedure and see that the symbol appears on the screen after 10 to 15 seconds.
The flashing of this icon 2 to 3 times within these 10 to 15 seconds shows the resetting of the Ford BMS.
You can do the same procedure after 20 to 20 minutes if no icon appears on the screen. Then, turn off the vehicle and ignition switch and wait for approximately half an hour.
Disconnecting negative terminal
Disengage the negative terminal and find the reset button on the side of the positive terminal.
Press this button for 3-6 seconds to restart the battery management system. Then, connect the negative terminal again, start your truck and move a few miles forward.
Turn off the ignition switch and do the whole procedure again. Now you can move forward without getting worried about any problems.
Why would you reset the Ford Battery management system?
The resetting procedure is necessary to remove the errors and bugs from the system because it can decrease the durability of the batteries and make them less effective.
The battery often becomes dead and provides no electrical supply to the electrical system. Therefore, you need to change them to fix the problem.
Adding a new battery requires the recalibration procedure to fit into the system. In addition, it is also necessary to increase its working efficiency and durability.
The recalibration also optimizes its function and saves the power for later use. You need to update the new system in it for its appropriate functioning.
It can show the feature of the old one and not conserve the power when you do not reset the new ones.
Fix battery issues
The errors or issues are common in every part of the truck, including batteries. As a result, you cannot charge them accurately and supply the power to other electrical accessories.
These cannot hold the charge and charge from the alternators due to faulty components, sensors, or computer systems.
It can fix the bugs that give the wrong command to the system and cause improper charging conditions.
Less charging is problematic because it can cause the fuse to blow out and headlights to become dim during driving at night.
Increase durability and performance
The battery life decreases when there is some issue with its components. The resetting procedure helps to remove all of these errors from the system and optimizes its condition.
It can improve overall performance and durability. The deletion of errors and issues increases their working performance, and it can conserve power in a better way.
Moreover, it is inexpensive and easy and does not take excessive time.
It is also a better option than a replacement because it takes more time and money.
Prevent the battery from overheating
The overheating in these components comes due to overcharging. It can also explode when you give them a power supply more than its original capacity.
The faulty and bad alternators also cause overcharging issues. Overcharging also decreases their life and causes premature aging due to excessive water accumulation.
The incorrect current supply due to malfunctioned system can overload them with high ampere current.
The BMS negotiate these errors and prevent them from overheating and overcharging issues by omitting the errors.
How often to reset the Ford Battery management system?
It is necessary to do this procedure to remove the possible errors from the Ford BMS. You can do this process after every 2 to 3 weeks.
The time frame also depends on the type and model of the trucks. In addition, the chances of errors increases, and you have to recalibrate the system early after covering a long mileage.
