Well I'm glad I read this thread. Never knew what a "BMS" was before. My battery threw a low battery light one day when I had the key on engine off, which I thought was weird. I noticed on Wednesday when I was coming home from work, my HVAC controls completely turned off then turned back on about a minute after I left the parking lot. Then the next morning the car was dead, and I needed another jump when I was leaving work that afternoon. Got the battery replaced yesterday, but had no idea about this "Battery Monitor System" that needed reset.

Gonna get that software downloaded and OBD cable purchased so I can take care of that. I'll look after I post this, but is there a stickied thread about what can be done with FORScan? Anything cool? lol...

Thanks, y'all.

Nothing new to add to the helpful information that's already been posted, but I just wanted to mention that I replaced my battery about a week or so ago and after buying the ScanTool OBDII/USB cable and downloading FORScan, I was able to reset my BMS in less than a minute.

It couldn't have been easier, so thank you everyone for sharing your tips and knowledge.

Interesting stuff..so...is your 2014 deemed to be the MK3.5 model? We may need others to chime in. The reason I ask is I've seen threads stating that the Forscan product is incompatible with the 2015 model MK3.5.
But, if your2014 is the MK3.5 then I'll go ahead and buy what you have and reset the BMS on my 2015.
Thanks

Ductape91 is correct: mine is not a 3.5.

Regarding FORScan's compatibility with your car, I see mention of Focus models through 2017 in their update lists, so I would think your car should certainly work with FORScan. The FORScan program is free, and the ScanTool cable is cheap and handy enough that I would buy it anyways, because surely it could be used for something some time down the road.

Hopefully someone more "in the know" than myself chimes in soon to help you get a solution, but at least from what I read on their site, FORScan should work with your car.

So. Stupid question, how can I tell if my focus has the BMS and smart charging system that needs to be reset? Is there something I should be looking for like a sensor somewhere or is a different type of battery than a standard led acid battery? I've got 2 Foci (13' & 14') both will need batteries before the heat of the summer. Thanks for any assistance!
