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 RUclips 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.
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.
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!
Hi, initially (as im UK based) the video was mainly for european vehicles, but the video seems to have taken off in the US.......Glad it helped
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?
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!
Worked perfectly with my 2016 S-max. Thanks
This one is the winner. Make sure you deactivate your alarm before resetting. It took me a couple of times to figure it out. Good luck.
Carried out to instructions on 2016 focus diesel stop start works everytime, car had a service recently told garage they said battery needed charging battery was charged worked about 3 times then stopped working the battery is four years old so i would imagine the voltage lower than a brand new battery Many thanks
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!
did it worked actually? i need to replace my battery on my 2017
Yes it worked man
Great video mate , done my 2014 kuga followed your video through the process and was spot on . Thanks !
Thank you, this just saved me from getting stung by National Tyres here in the UK, they wanted 35 pounds for this simple procedure.
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!
It is quicker using this method than getting my scan tool hooked up and using that, which doesn't always work anyway. 👍
I don’t have fog lamps and the method in the description worked on my 2018 f-350. Thanks!
Thanks, the car I've just bought is a late 2011 Mk4 Mondeo econetic which is supposed to have Stop-Start, I didn't think it had until I ran this reset.
Worked in my wife's 17 fusion brights and brake method thank you
This works , thank you , my Ford Focus mk 3 1.6 petrol had a flat battery , I jumped it with a spare battery , then the engine malfunction light appeared.. I pressed my bottom left fog 5 times then hazards 10 .. started engine and malfunction light gone , as we say in the uk 🇬🇧 bloody amazing. Your a star my friend ..
its really meant for re-setting the bms charging data when a new battery is fitted
You saved my freaking life man. I could not for my life reset the freaking battery!!!!!!!! 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.
no problem
Does this work if you don't have push button start? Do you turn the key on (without starting)?
Fyi, just tried it and it looks like it worked. Got the battery light to flash
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.
I just did this on my 2015 Edge Sport, worked.. thank you!
This worked on my 2015 Screw, F150, 2.7 ecoboost, as well. Thank you.
This also worked on a 2016 Ford Fusion 2.5L. Battery indicator flashed on dashboard twice.
Ford escape 2013 in Canada. Tricks with 5x high beam and 3x brake work well!! Thank you very much!!
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.
Hi. Thanks a lot. It works on a 2016 Ford C-Max energi. It was going on save mode and not starting at least it was jump it. I just had to recharge the battery so the BMS gets the most accurate information. Blessings
Hi, I have the same car. It doesn’t seem to work on mine. Trying to figure out if I’m doing something wrong. Did you do anything different on yours? Thanks in advance.
Mondeo 2011 2.0L Duratorq CR TC (140PS) - I have to say this sounds like a wind-up, but I tried it and it solved a very annoying problem! Thank you!
which method did you choose?
This procedure worked for me on a 2012 Ford Focus 1.0L Ecoboost RHD. Thanks for posting. Appreciated.
This worked easily on ford focus mk3. Thank you for this video. Helped me
Great video. Worked on my Focus 1.6 tdci, 2012.Thanks.
Thanks for watching
This worked on my 2013 Focus Zetec S Ecoboost. Cheers
Thank you I've just done this as my stop start wasn't working and now is thanks to u 👌👍👍
Worked for Ford fiesta 2018 zetec automatic. Flash lights 5 times, press break pedal 3 times, wait 5 secs, and bms resets.
Awesome..love these quick tips n tricks.. Pity i cant remember them all
Thanks for your video. Tried on a 2018 ford kuga and while doing the reset process... the battery indicator did not blink as explainned.... however it did work the reser and auto start stop now is working fine.
Sometimes I find the alternative method better
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, wooooohooooo. Saved me from hooking up my laptop through Froscan and possibly bricking the car (curiosity always gets the best of me).
How do you know it worked? What were the signs that it was successful?
@@Jeppedy battery light flashes 3 times.
@@imgerrydee I did that and the light flashed 8 times, then turned off ignition and back on and waited 30 seconds and it flashed again. Snake oil.
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.
The procedure is in the video description. Thanks for watching
@@SYDiagnostics should the battery be fully charged before the reset?
@@me109g4 Thats the idea, the process is to be carried out after a battery replacement. It seems most who've watched it a re-setting it un necessarily for a stop start issue
@@SYDiagnostics my new battery was only charged at around 80%,, so i will charge to 100% before doing this. Thanks.
My 2015 Taurus has no battery symbol.
Thank you so much for this reset procedure. 👍🤠👍
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
Thanx a lot for this beautiful video I just tried it now at night on my 2014 Lincoln MKT but the battery light I can’t see it on the dash board but check engine start flashing I tried booth methods actually, I’ll wait till tomorrow and see
By chance I changed the alternator and battery for that msg “check charging system “ and the light after new alternator and battery was on and off
Thank
You SIR deserve a medal! Thank you.
Glad it helped!
What’s the reason that you need to do a battery reset ?
Because I have my mustang 2012 I replaced a new alternator & battery
Then the battery sign start blinkin while driving & sometimes leaving the car off for 12+ hours the battery becomes dead !
If you press the rear fog light switch 5 times (on-off-on-off-on), the lights are ON during the procedure. Well, I read elsewhere (ford mondeo mk5 forum), you should press the switch 6 times - actually is it 12 times (on-off-on-off-on-off-on-off-on-off-on-off) - so that the lights stay OFF. The analog procedure for the hazard lights (on-off-on-off-on-off; you have to press the switch 6 times; NOT only 3 times). Any thoughts on that? Thanks.
I had to switch the headlights to Auto to get this to work on a 2017 Ford Escape Trend - New Zealand version. The dash engine light flashed three times when finished.
Tried it on my dad's 2017 Ford F-150. This got it going again. It had an issue with a warning sign that said "system off to save battery". The steering would lock off and all the lights on front panel would turn off locking the power steering. This kept happening on and off. It eventually came to where the front panels lights would turn off after ignition. When he shut down the engine, all the lights of the front panel came back on. It is still running now and we'll see where it goes from here. Thanks for the help.
Did it work for you because I am having the same exact problems
Thank you so much. My 2010 everest starts after the process you've shared. God bless
If it does not work then there is an alternative method in the video description. Why are you needing to reset it?
Thanks Steve for this. Came in handy
I thrived the alternate method & the battery light didn’t blink 3 times. Did I miss something? Does the vehicle have to be running? Thanks!
Hi , working on 2021 renault clio fault while driving everything cutting out for 2 seconds engine , power steering and no dash lights , speedo rev counter etc only does it in the morning after a few minutes of driving , no codes could the bms on the battery cause this and would it be okay to disconnect this or bypass it to try it ?
My gear shift light becomes really dark when i turn on my headlight help! I just got new batteries
Very KNOWLEDGEABLE
Thanks 👍
SY Diagnostics
From Nick Ayivor from London England UK 🇬🇧
Does this work on the new s max…it has 2 batteries & an inverter so I’m suspicious the failure to stop start is because the battery is actually low because 11.9v when off but I suspect that’s the domestic battery
I did the 5 times high beam switch and 3 times brake light worked great did not even lose my radio presets.
Yes, this is what I did for my 2015 Ford Escape as well. I will try either of these on my 2013 Ford Mustang. Yes, I did replace both batteries, not doing this for fun. :)
Works on Galaxy MK2 2013. 😉
MANY THANKS.
What about the small battery icon that's located in the top center display? I get a warning of door ajar and a little battery light comes on that resembles a cell phone battery icon
Tried the alternate method on my 2013 fusion. It didn’t seem to do anything.
Should this work for a 2013 Ford Edge? I tried both methods and doesn't seem to work.
Does this work On 2017Ford Taurus SEL, After tune up?
Because it’s saying check braking system.
Hi mate I have a Ford kuga 2016 I have got the dreaded problem with the ambient temperature sensor will do this help it in. Anyway once I’ve changed the sensor with a new one. Thanks in advance Wayne
Does this process work on Resetting Braking System on 2017 Ford Taurus SEL?
Thank you for this video because my husband is on the phone with the dealership right now and I was able to have him read this to them on the phone as they’re trying to convince him it should cost $175 to do this before they can diagnose my vehicle 😂😂 it made it worth every second of this hassle right now lmao now they’re bonding over it
2017 Ford S Max (UK) what worked for me push the start button (without starting the engine) then flash headlights 5 times and press brake 3 times.
Tried this and the battery lights flashed three time as it should like it’s been reset. When I lock the vehicle the alarm keeps going off? Any ideas?
Hello from South Africa. 5 x flash high beam and 3 x brake worked a treat on my 2016 Ford Everest! Thanks for your help 👍🏻
thanks the high beam and brake trick worked for me
Okay I read in the text where it said you have to replace the battery with the exact type of battery I want to replace the flooded lead with a fiberglass Matt battery I know it lasts longer because the fiberglass Matt is between each of the lead plates and prevents vibration and shorting out of the plates I've had fiberglass batteries last as long as 8 or more years do you know if that's possible to switch to a AGM battery
You have a new subscriber.
You saved me! I replaced the battery and the start /stop didn't work for a while.
I think after that, I will be fine. Thank you!!!
I tried the 5 high beams and 3 brake presses on my 2013 Fusion and there is no blinking battery icon? Does a 2013 Fusion even have a battery light? I dont have a rear fog. ty
So I managed to figure out how to do it, incase anyone else with a North American Ford Fiesta (ST in my case) needs this done!
You press the start button without having your foot on the brake so power is on in accessory mode, but engine isn't running, then you'll need to pull the High Beam lever all the way where it toggles and stays on/off (not half pull where it toggles briefly) toggle that on / off 5x and then hit the brakes 3x.
i give this method as an alternative in the video description below
Same lang po ba process sa 2016 ambiente sir? Salamat
It didn't work on Ford Fiesta 2015 Ecoboost. The headlights should be on when doing this procedure?
5 Times high beam and 3 Times brake for Ford ecosport 1.0 ecoboost 2018 work succesfully thx🤗🤗🤗🤗
Does this work in Ranger Raptor 2020?
Thank you sir 😁✌️
Going to try this my stop start stopped working before Christmas 👍
Did it work or was it battery?
@@MellowPuffNZ was a bad connection
Hi sir, 2014 ford ranger no start , only crank , after scan bcm have 17 eror, it want reset any more , what to do any idea??
Yesssssssssssss! Another satisfied customer. Many thanks.
Thanks worked perfectly on my 2016 F150 (alternate method no rear fog lights)
What alternate method you use? I also got a 2016 f150
@@214vince1 the instructions for alternative method(without fog lamps) is in the description below the video. I did the steps exactly as instructed within the 10 seconds and battery light blinked 3 times telling me it was successful.
Hi, most of the time when I do this procedure, my battery light only flashes 2 times at the end of the process.. can anyone tell me what this means?
Alternate method worked for my 2015 Ford F150! Thanks!
Whats the alternate method? I don't see it
its in the video description
Is there a way to turn on the digital compass on a 2014 ford kuga. I have it ticked in settings but it stills shows blank. I checked all fuses etc. I had my battery replaced and after that it did not show
may be worth doing a sync re-set, I'll try to do a video on doing it
Will this work on a 2020 explorer st?
Sweet! Just what I was looking for to reset 2018 F150. Thank you!
I don't have a rear defroster on my F150... I was unaware that any of them did. Did you just hit the defroster button?
Could this work on 2015 Transit custom?
Will this work on a 2009 Mondeo?
Hi and thank you , apart from resolving the stop start will this reset improve the general running of the Fiesta ?
No not at all I'm afraid
@@SYDiagnostics Thank you for your reply , I bought the Fiesta from a main Ford agent about 4 months ago and presumed that the stop start had been disabled . It now works correctly and the annoying issue with the engine reving slightly when lifting my foot off the clutch has now gone . Cheers .
Does this work for 2011 Ford Edge? Thx
Tried this on my ford focus zetec 1.6 diesel and still doesnt work. Got the car few days ago as i upgraded from my old car.
Worked on 2012 Smax 2.0 diesel. Thanks.
2012 Focus S...i dont have this fancy stuff (rear fog lights, front fog lights, etc). Tried high beam flash 5x and brake 3x and that didnt work...looking for some help please
any other trick
When you do this, make sure your doors, trunk, and hood are all shut. At first, I did the 5-3 method, but it worked after pressing it about 7-9 times each.
Do you mean pressing brake pedal 7 to 9 times? Thanks Anthony
Do you have to turn on the car ? Do i need to turn off my alarm first or not? Thanks.
Nice 'How To' 👍🏻
I just purchased a 2020 F150 with the 2.7L engine in it, will this process work when it comes time for me to replace my battery. I guess I am just an old boy scout at heart, always be prepared. Thank you!
Im UK based so this isnt a vehicle we have. I see others have had issues with this process on the older F series, but i'd imagine it'd work for yours
what are REAR fog lamps ?
I've just had my battery replaced on my 16 plate grand cmax as the old one was completely flat, asked whether they needed to reset the monitoring and got told no. I've had it out for a run, stop start working fine and no issues, no warnings on dash but is it worth still performing this reset?
It should re calibrate itself in all fairness.
What year was this on...because when I do this it goes into "Train Front Left Tire" I'm trying to reset BMS on F-150 2013 model. Thanks. for vid....
There is an alternative method in the description. The video seems to have taken off more in US than it has in Europe where I am....
Hello! Will this method work on C-Max 2.0 2015 redisigned model. I am from EU. Thanks mate
Yes it should work if you have a battery monitor sensor on your negative battery cable
The bateery flashed when i did this on 2012 focus 1ltr eco boost but the stop start still isnt working
the process isnt intended as a stop start fix. It is a process required when changing the battery . by the popularity of the video it seems to have been assumed this is a stop start fix. Using forscan or similar you should be able to see the stop start inhibitors and find your problem. Most likely still battery state of charge
Changed the battery on my kuga mk2.5, and this didn't appear to work. Though its been a week or so and things appear to be working as normal. My question is how do i know if its reset or not and what are the consequences if it hasnt. Thank you.
There is an alternative method in the video description. The BMS reset will clear the aging data of the old battery and thus the BCM and PCM will have fresh data in which to calculate the charge rates for the alternator
Worked on 2015 escape titanium thanks
Good to hear
How did you do it on your escape?
My local ford dealer sed its recommended to leav the car with ignition off for 3hrs after this process so the car can determine the battery level of health or something like that. Is that right?
Yes. Once a reading below 100mV is recognised then the BMS can calculate correctly
@SYDiagnostics thanks for your reply 👍
I believe there's a difference between "Battery Registration" and the "BMS Reset". Is that right? I think the former changes the charging profile to the type of battery?? I would like to know since I have installed an AGM battery in my 2014 Ford F150 pick up. Thanks!
Correct, the BMS reset will only "tell" the BCM a new battery has been fitted and the charge rate/output will be according to the reported values of the BMS, load sensing inputs relevant to the battery fitted. I've seen within the bcm configuration / asbuilt details different battery profiles, so that would be a place to start. You would need a licenced forscan or IDS to change this (if available)
@@SYDiagnostics Thanks for your reply. I guess I will need to look into this!
Hi all, I changed battery on my C-Max II (2011) because there was "Low battery" warning. After replacing the battery the warning message still appears. So I tried this BMS reseting. My car does not have START-STOP system, but BMS unit is connected on negative connector. I tried the procedure (key on position II, 5x rear fog and 3x warning lights). It is necessary to wait approx. 15 seconds while the battery symbol starts flashing. It flashed only two times, not three times. I tried again several times and finally it flashed 3 times. Hope the warning message will not appear again. If yes, then the new battery should be charged not in a car but with standard charger, I think. Or BMS unit is not working properly :(
The video was aimed at showing a method to reset the bms after a battery change (like you) it seems most people have adopted it for stop start issues on used batteries 😒
What is the reset process for a 2013 Ford Edge Limited? I don't have a Rear Fog Lamp button/switch/toggle. Thanks.
