Will a new DME chip cause check engine light?

#1
After installing a performance chip now my check engine light is on. I checked the codes and it said Battery Voltage/DME Main Relay. Since my battery was dead I figured that was the problem but now after replacing the batter the light is still on :-/ The car runs great and I can definitly feel a difference with the chip so I'm not too concerned but I would like to put my mind at ease...

Thanks.
