I'm so glad they've made cars like this! You can't just change the battery and be done. What is the point of this BMS if it's not sophisticated enough to reset itself nor does it seem to help battery life at all?

Bob R from Michigan: This method of resetting the BMS might work if my car had the rear fog lamp switch and a battery warning lamp in the instrument cluster, but it has neither, and those devices seem to be essential to this procedure being successful in resetting the BMS. I did what another YouTube video suggested and disconnected the BMS sensor ( which I had replaced prior in an attempt to cure this problem after replacing the car's five year old battery) and that method was successful so far after two days.

I have a 2015 Ford F150 SuperCrew with a 2.7L engine. The method that worked for me was option 2, the high beam & brake pedal. I live in the U.S. Thanks SY Diagnostics!

[martinreid]

Did the ignition on, high beam flash 5 times and step on brake 3 times and worked perfectly on my UK 2019 Galaxy. Thank you!

Tried this after a new battery purchased on a 2017 F250 6.2 gas and it seems to have worked. I used the procedure that you turn vehicle power on, not start engine. Pull the high beam light lever 5 times then press and fully release the brakes 3 times. About 2 seconds later I saw the batter check light flash 3 or 4 times. Guess that means it worked. Thanks for the info.

You saved my freaking life man. I could not for my life reset the freaking Tried that method at first. It it didn’t work. Went down to the comments and found your other method. On my 2016 Ford F-150. 1. Get in truck close the door. Press the push to start, BUT NOT TURN IT ON. Simply press the push to start. And wait for the battery light to come on. 2. Flash brights 5 times, then press and release the breaks 3 times. Wait about 5-10 seconds and it will flash. When you press the brakes the second time it won’t go in as far. Just make sure to release the brakes fully after each press. Remove you foot completely to make sure you do it right.

The method in the description worked for my 2018 f150 stx! I would turn the truck off and the radio would go off after about 1 minute to save battery but now works normally. Thank you!

If you have a 2017 Ford Expedition, it’s the bright lights 5-times, then the breaks 3-times, you won’t see the battery in the dash, it will be the engine logo light that will flash

Finally found a way for the US/Canada made Ford vehicles to reset BMS. First make sure all windows doors/hatch's are closed. Turn ignition to the on position (Don't start car) wait 10 seconds, Flash your highbeams 5-7 times, then press your brake pedal 3 times, Wait for battery light to flash. DONE in under 1 minute and you saved around 150 bucks from Greedy dealerships ! It may be a good idea to do this at night when you last park your vehicle to let the BMS to monitor and adjust to your new battery's charge state, but not sure about this last step, up to you.

I had a 2017 Ford Escape Titanium (in the US). Since I don't have a rear fog light switch, I tried the alternate procedure. It's a keyless ignition, so I wasn't sure if I was doing it right. I tried it 3 times, each time being more careful than the last. I never saw the battery light on the dash blink and it wouldn't auto stop/start. However, when I went to drive it the next day, it was working. I traded it in that day, so I'm glad it worked eventually. Thanks for the video!

[btoogran]

Did the ignition on, high beam flash 5 times and step on brake 3 times to my 2014 Escape here in Canada and it worked, Saved me from hooking up my laptop through Froscan and possibly bricking the car (curiosity always gets the best of me).

[alrack]

I did the 5 times high beam switch and 3 times brake light worked great did not even lose my radio presets.

[louithrottler]

Mate cheers. Just to confirm - I bought a 2018 Mondeo Estate 1.5l Econetic Diesel (manual) and after just 2 weeks I was hit with the auto-start-stop issue. I remember briefly seeing a message about 'auto city stop sensor damaged' or some bs then that was it. I was driving it like a little baby girl so I knew it was nothing I'd done. I ended up here and (for me) the second method worked first time.
1) Get in, close door, press ignition (engine off)
2) Quickly flash your main beam 5 times and then press the brake 3 times
3) After 5-10 seconds the battery icon flashes 3 times to confirm.

Magic. Mate you da man. Worked like a charm.

5 Times high beam and 3 Times brake for Ford ecosport 1.0 ecoboost 2018 work succesfully thx🤗🤗🤗🤗

[mrb]

I have a 2015 Ford Transit 350 (UK spec) and the process is slightly different.
1. Ignition on 2nd click
2. Turn Lights on Main beam
3. Press rear fog light 5 times
4. Press hazard lights 10 times.
5. Wait approx 5 secs, the battery light will flash a few times. JOB DONE
6. Bring it for a 10 miles drive, this will 'program' it permanently.

[mdsymonds]

It is quicker using this method than getting my scan tool hooked up and using that, which doesn't always work anyway. 👍

[DalekBass]

This procedure worked for me on a 2012 Ford Focus 1.0L Ecoboost RHD. Thanks for posting. Appreciated.

[rogerbarfell]

Worked in my wife's 17 fusion brights and brake method thank you

[gabrielpefcik]

I just replaced a brand new battery on my " 2015 Ford Focus 1.5l Duratorq (diesel) Zetec S " and by chance get around this video,
I have to say :
Description is spot on and it worked on my car, battery symbol on dashboard definitely flashed 3 times after few second I did it.
Thank you for sharing this video and description with us ordinary guys "dependant on rip-off dealership companies charges" !
Right to repair for everyone. Thanks again God bless

Thank you, this just saved me from getting stung by National Tyres here in the UK, they wanted 35 pounds for this simple procedure.
