Hello and welcome to Justanswer. My name is XXXXX X am a Automotive Mechanic here to help you with your problem.
There is something you can try. Do a global reset on the system this will be like rebooting the computer. Disconnect both the negative and positive battery cables for 5 minutes before reconnecting the battery cables make sure they are both off touch them together for 15-30 seconds this will ensure the residual gets discharged. Than reconnect the cables
If the problem is still there yu will most likely need to replace the deck because of a internal short on the circuit board
they just changed my battery
Changing the battery is not the same thing
did this cause the problem?
This is how you do the global reset it has to be done in this order to reset
Did it work before the battery was changed
This might do the trick than.. I would try it because if the module is getting inaccurate values this will reset it
They should be willing to fix this at no cost. Make sure they know it was perfect before they changed the battery
