new to the forum, and this issue brought me here.

i replaced my battery with a new, off the shelf, OEM. reset the BMS using FORscan 2.3.25, and the battery light is still on. checked voltage, and it's charging around 14.1-14.25ish, so that's ok. reset it again, and the battery light is still on. what am i missing? the battery holds a charge..ok? when the vehicle is off it's in the high 12s, when things are running (with the engine off), low 12s/high 11s..not enough of a drain to say that the battery light should be on. i'm at a loss here and would really appreciate some help. thanks.

Did you clear the code? It might take a while to clear on its own.

I have somewhat the same problem. Bought oem battery and used forscan. Seemed to work and no lights on dash. When its charging its says 14.4 but when I turn it off and do an 8hr shift ive checked it where the battery dropped all the way down to 11.7 and i dont have battery light on. My car starts fine and lights dont flicker. Ive heard you can leave the battery disconnected for 8hrs and it will reset the BMS as well.

i erased the DTC codes, yeah. unless that's wrong. it was my first time using FORScan, but it made sense at the time.

i hooked up my car, went to the BMS reset, let it do it's thing (takes all of 25 seconds), then went to DTC, erased the codes that were there, started the car

nothing? does the battery light come on and stay on until the battery charge level is at a certain amount? (ie - comes on if below, say, 95%)

is it possible that the BMS reset doesn't work?
