Check Brake system message with ABS module code

[newdeal99]

I just did some updates in FDRS including the BCM and now I have a check brake system message and also a 12v battery state of charge error message that come up on my display when I start the vehicle. This didn't happen before the update. The ABS module error is related to inadequate voltage. I get the error even when I have a charger on the battery and when I start the vehicle. Is my battery bad or is there something else going on? I tried resetting the battery learned values but that didn't work. Just looking for some help on how to fix this.

One of two options.

Drive it 20 mins or so and see if it goes away If not

The other option we have to roll you back to the old BCM version

I had a similar issue last week with mine. ABS kept saying battery low state of charge, "DTC U3003-16". I checked the battery state of charge in BCM and it was at 84%. Reset the ABS and BCM modules with no help, resting the BMS did not help either. I Let the truck sit over night and through the next day while I was at work (about 16 hours untouched). When I got home I was going to try other steps to try and clear the message all was perfect, no DTC's. Im guessing the battery management system had to go through its process. If I remember correctly the Battery Monitoring System normally take about 8 hours to fully calibrate. I have not had any issues since everything cleared itself.
