Hi, have you ever encountered the error above ? The car is an S60 II ( 2014 ) .
It seems thatr this error is related to battery voltage , but I changed the main battery with a new one, and the error is still there.( even if i cleared all the errors ). Could be related to the second/support battery ?
Any advices, please?
Thanks!

@sizan first of all. Always replace both batteries at the same time. They are both of equal age and wear level. Charge new batteries before you install them, this is really important. After changing the main battery, you have to perform a BMS reset. In Vdash this function can be found by clicking on the CEM under the advanced options. After this reset is done, lock the car and leave it alone for at least 4 hours.

Thank you @T5-T6-Schnappi !!
I am asking just to be sure : since I already changed the main baterry and reseted the BMS sensor, after I change the support battery it is required a new reset of BMS sensor ? and the lock the car for 4 hours part? What would be the best approach ?

BMS reset is only needed after replacing the main battery. The support battery has no sensor.
In your case simply do nothing. The battery management still adapts to the new battery, but it takes a little bit longer to be correct. Nothing to worry about. The BMS reset resets the battery timer, which is the only way to precisly tell the age of the battery or at least when it was installed in your car, and also tells the battery management to adapt to a new battery. This should never be performed without actually replacing the main battery.
