DirectorMan Report post Posted January 19 I want to perform a BMS reset, but I don't see the 12v icon on my display when I start it up in accessory mode. Is there a setting to make it visible? Quote Share this post Link to post Share on other sites

DirectorMan Report post Posted January 19 That is exactly why I want to do it, but I don’t see the battery icon. Quote Share this post Link to post Share on other sites
2014FordFusionSE Report post Posted January 20 I checked my Fusion as well. When you switch on the car without actually starting it, it displays all the dashboard lights. I don't see one for 12v or batteries which is probably why you're not seeing it either. Did you just replace the battery? Quote Share this post Link to post Share on other sites
DirectorMan Report post Posted January 20 Yes, I did, and I wanted to reset the BMS following the instructions on the YouTube videos, but if there is no 12v battery icon on the dashboard I have no way of knowing if the reset was successful, since the icon is supposed to flash once the BMS has been reset.

2014FordFusionSE Report post Posted January 20 I replaced the 12v battery on my Fusion a couple of years ago. I didn't do any reset and it works fine. I wouldn't worry about it. Quote Share this post Link to post Share on other sites
DirectorMan Report post Posted January 20 Thanks. I’ll try not to. There was a two or three day gap between when I removed the old battery and installed the new one. I assumed that I would have to reconfigure the radio presets, etc., but to my surprise when I started the car everything was intact. Does that make sense?

Cobra348 Report post Posted January 22 I agree with 2014FordFusionSE. I had my 12v battery replaced and nothing special needed to be done. Quote Share this post Link to post Share on other sites
DirectorMan Report post Posted January 23 The car has been performing well, so I've put that concern behind me. I'm still at a loss to explain how my presets survived the battery being disconnected for a few days. Quote Share this post Link to post Share on other sites

DirectorMan Report post Posted January 23 That was my assumption as well when I started the car and everything was as it used to be. My expectations were set by the YouTube video linked below that indicated that without connecting a memory saver prior to replacing the battery all configurations would be lost. I'm a happy camper since I didn't have to reconfigure everything from scratch. Thanks for your insights. https://youtu.be/gQHg5m5HDHM?si=8IyFhAUFRbgzfj9a Quote Share this post Link to post Share on other sites
