- Hi and Welcome to another Dans Diagnostic video.
Today I talk you through the basics of the Ford Battery Monitoring Sensor (BMS) before showing you how to reset the system on the MK8 Ford Fiesta. This procedure will also work on newer Ford vehicles and older models with a BMS fitted but without a rear fog button.

Thank you for watching and commenting 👍
It worked for
Me On my 2018 stang eco boost convertible
Great vid
I've just reset bsm on my 2020 st focus and straight away auto stop and start is working and smart locks on both doors are working. My battery is 3 years old so should have set bsm as my cars bsm will think my battery is new ?
I had problem from FordPass application said distance etc desactive for protect battery and i gone Ford Service one night they did charge my battery and they told there is no defaut,and after day still my auto start stop and door of passenger keyless doesnt works after this video everything works well ty mate (my car fiesta mk8 st)
You are the best. Authorized Ford service center couldn't fix start/stop system since one year. Your way managed to do this. Start-stop is now working well! I didn't switch battery, previous owner only ride a car in short distances.
Thank you!
Maybe you or others could help on another challenge? How should eco mode work on mk8 st 2019 (switching to 2 cylinders) any icon on the dashboard should show? How I should know if it's on or off?
Thank you. Is it the ST Line 1.0l ecoboost you're talking about? The car doesn't let you know that it has entered/exited cylinder deactivation mode
@@DansDiagnostics I'm satisfied user of 2019 Mk8 St3 1.5l 200KM with performance package. Driving on normal mode I can't recognize when car runs on 2 cylinders. Previous owner mentioned that somewhere on dash "eco" icon was visible after cylinder deactivation. That is why I'm looking for more details.
I have a 2020 fiesta and I have to bump start it. Do I have to do this procedure because it has put the engine management light on
HI DAN, Im from south africa you got anymore of these resets please do post
Having problems with 2018 Smax, the dealer recalled and changed something on the BMS and the stop/start and the heated windscreen stopped working. No error codes were showing but it still didn't work. I think they possibly forgot to reset the BMS so when I get it back I will do it. One question, should I disconnect the battery before charging or charge it in-situ and then reset BMS. Also, does the stop/start take its information from the BMS level because I have read that if you reset the BNS with a used and slightly depleted battery it will work because of the the new lower threshold level. The stop/start does not bother me too much but the non-working heated screen is a real PITA.
I have a 2 year old mk8 ST. It shows "turn off ignition or start engine". Is it OK to try the rest procedure without changing battery? Few months backs I didn't use the car for many weeks after that it's in regular use. I notice the message frequently these days
@Dans Diagnostics, what do you mean by ‘car must have a rest period of at least 3 hours in 7 days’?
Park your vehicle and do not use or start the vehicle for 4 hours then all is good. Only have to do once.
My car is like 6 months old. All works but Ford pass keeps throwing deep sleep mode warnings. Battery voltage is 12,2 and the car is used daily.
Even after doing 90km of highway at speeds of 120-130km/h, throws the same issue of deep sleep.
You think this reset may help?
Hi, is it possible to completely remove the battery without first taking off the air filter? Thanx in advance.
Hey, thank you for your comment. If I remember correctly the battery can be removed on the MK8 Ford Fiesta without the need to remove the air filter housing but it is very tight and it is easier/safer to remove the air filter housing first. Attempting to remove the battery without first removing the air filter housing can result in damaged parts or personal injury so I would advise against it. Hope this helps
I have a kuga 17 plate just replaced the battery as was the original and was getting slow starts and stop start greys out cars all working as should with new battery but still no stop start I have tried your method but no luck
I've tried on my 2012 ka, my battery light doesn't flash, would this appear on my LCD cluster screen as mine doesnt not work ? Or is it where the red battery light up is?
Hi, thanks for your tutorial.
There is a part doesn't clear for me, it's what mean exactly "car must have a rest period of at least 3hours in 7 day period"
Hi Dans, thanks for sharing. I have fiesta 1.5 S AT 2014 is it possible to use the same method on resetting BMS after changing the battery as you shows in the video?
Hi, thanks for watching and commenting.
This method works on most Ford vehicles that I have tried it on, however there is another reset procedure that usually works when this one doesn't.
Ignition on
Rear Fog pressed 5 times
Hazard switch pressed 3 times
You should see the battery light flash on the cluster if it has worked.
Hope this helps
I have this problem with the start stop not working. When i do the reset (inside the car) it works for 1 drive but the next day it doesnt work again...any tips for this?
Hello.. can this remove the battery warning lights as well? Recently i replaced my alternator yet my battery warning light is still on..
Hi Dan, thanks for this. I have a MK3 Focus Tit X, are there 2 ways to reset this? Some videos suggest pressing rear fog x5 and then hazard x5
Hi, yes, this method works on the newer cars and on older ones without a rear fog button. Yours will need the ignition on, press the rear fog 5 times then the hazard switch 3 times and you should see the battery symbol flash on your cluster. Hope this helps.
@@DansDiagnostics that's great, thank you. I'll give this a try on Monday when the new battery arrives 👍🏻
Hey man in worked !
Question, we’ve got a ford st line 2019
But both of the front window bounce automatically back when we want to close them, we cant fix the problem, do you got any idea how to fix this?
It most likely needs a software update or reset on the Drivers Door Module (DDM). Theres a manual reset procedure but this doesn't tend to work too well when the windows bounce back like they do. IF I remember correctly you start with the window down and hold the window switch up until it reaches the top, then hold down till it goes all the way down, release the switch then press it down and hold for one second, then hold up till it gets to the top. IF it doesn't bounce back press and hold up for one second then try the one touch down and up and hopefully it'll reset. If not I'm either not remembering it correctly or it most likely needs the DDM update/reset. It is under warranty tho so you could get it sorted at your local Ford dealership 😁
@@DansDiagnostics yeahh!
Yesterday i installed the New update!
But i didnt worked, ive readed On internet that its a safety option for when something come in between it automatically bounce back, hands of little childeren as example
Can’t you make a video for the manual procedure? I’d really appreciate it!
Tried this on a 2017 kuga didn't work,any other way cheers
The reset for your vehicle should be…. Ignition on, press rear fog light 5 times, then hazard warning lights 3 times.
Battery light should then flash 3 times to indicate it’s reset.
Hello,
Can you please tell me the dimensions of your battery? Do you have the spec?
Thank you!!
It’s an ‘H6’ or group 48
Nothing happened?
saves a bunch of £££'s and avoids taking to a garage.......
Thats what its all about mate eh. And its quick and easy 👌
