It can be easy to confuse resetting the battery on your Ford F-150 with the relearning process. To reset the Battery Management System (BMS), which temporarily disables electrical systems to detect any drain, all you need to do is nothing. That's right, nothing. Specifically, you should allow the vehicle to "sleep" for eight hours after replacing the battery. This means parking your vehicle, locking it fully, and turning off the ignition overnight. For the battery relearning process, turn the ignition on with the engine off. Then, toggle the high beams five times and press the brake pedal three times. If done correctly, the battery light will flash three times within 15 seconds after completing these steps.
I replaced the battery in my 2013 Ford F-150. I turned the ignition on without starting the engine. I activated the high beam switch five times, then pressed the brake pedal three times. Instead of the battery light flashing three times within 15 seconds, the engine light blinked three times. Is this an issue?
Unplug the negative battery cable and activate the headlight switch for approximately half a minute. Then, switch off the headlight and reconnect the battery cable, which will reset the ECM to its original factory settings.
I need to replace the battery in my 2013 Ford F-150 that has a Battery Management System (BMS). Regarding the instruction to disconnect the negative battery cable and turn on the headlights for 30 seconds, should I do this step after putting in the new battery and letting it sit for at least 8 hours?
I've tried flashing my high beams and stepping on the brake pedal, but my engine light flashes three times, not my battery light.
I can't believe how frustrating this situation is. Why is there never a straightforward solution to the problem of a Ford not starting right after putting in a new battery? Waiting for 8 hours is an absurd suggestion. It shouldn't take that long for the truck to adjust to a new battery.
By removing the negative cable, turning on the headlights for half a minute, and then reconnecting the negative cable, the reset was successfully completed.
If a 2021 Ford F-150 is put into deep sleep mode after being serviced and the battery is disconnected, it is important to let it sit untouched for 8 hours to avoid issues with Ford Pass. This has happened to me every time I've picked up my vehicle from Ford for an unrelated problem. On both occasions, they disconnected the battery while working on the APIM. A week or two later, my truck would unexpectedly enter deep sleep mode after being parked for a few hours. The only solution I've found is to disconnect and reconnect the battery, then leave it locked and untouched for 8 hours. It's frustrating, but it seems to be the only way to resolve the issue.
My 2015 F-150 Platinum doesn't have a traditional ignition to start or stop the engine. It uses a key fob with a key only for unlocking the door - there's no keyhole in the vehicle. I've seen reset instructions mentioning turning the ignition switch on and off, but I'm unsure how to do that without a physical ignition switch. How can I activate or deactivate the ignition on my truck?
To reset the BMS, leave the car with the doors locked for a minimum of 8 hours. To complete the relearning process, first warm the engine to its usual temperature, idle for at least 1 minute, and then drive the vehicle for a minimum of 10 miles at various speeds.
What is the current radio station and how can you program it after the PCM is installed?
Turn the key to start, switch to high beams, press the brake pedal, then turn the key off... This method definitely worked for me, with one major exception. Now my wife no longer requests intimacy. Life is going well, for sure!
A load of nonsense, in my opinion.
It functioned effectively, but I had to go through the learning process three times before the battery indicator blinked three times.
I might sound a bit crazy, but if you have a Ford truck made between 2015 and 2022 with the number pad near the steering wheel, here's a neat trick to bypass the 8-hour timer when replacing the battery. With the key out of the ignition, open the driver's door and enter the code 1234##2 on the pad. Close the door and then start your truck. This tip saved me when I replaced my battery, courtesy of my friend who works at Ford.
In 2019, with my 5.0-liter super crew, all I had to do was 1 replace the battery, 2 flick the high beams five times, and 3 press and release the brakes three times. This would cause the battery light to flash on and off within 15 seconds.
I've exhausted all options but the truck just won't start.
