00852 Fault Code

Can someone direct me how to clear fault code 00852?
 
From what I've read so far, I have this error code because I once had my battery disconnected.
 
thanks in advance!

Wat does the code mean?

This one took me a bit to sort through, according to the fault codes index 00852  is: - Loudspeaker(s) Front: Open Circuit.
 
But here's the catch, it's a false indication for my set-up. I installed RNS-E navigation and did not change the long coding to suit in 19-CAN Gateway for navigation present. The nav worked fine except I was getting a mis-leading fault code. Once i changed the long coding, I was good.
