DIC Service electrical system
2013 gran sport showing service electrical system on the DIC. Car was tuned by East Coast Supercharging back in 2014. Recently had a local performance shop clear any and all codes which there were a few that did not return but the service electrical system on the DIC came back almost immediately. Also had a scan tool hooked up recently and showed no codes. Been reading some forums about bad batteries and low voltage just looking for other similarities.

The C6 is very finicky when a main battery starts to lose it's power. Battery connections and corrosion on the posts are one cause, and also connections at the starter is good to check.
Under the passenger floor board, the 2 blue connectors can get shifted by a passenger pushing on the floorboard, and that can cause all sorts of weird alarms, codes etc.
Those can be disconnected, pins checked, some dielectric grease added, and put back together.
The C6 has a constant draw of approx .002 amps even with the car off, so it can be hard on batteries.
It is recommended to change the main battery on a regular schedule of approx 5 years or so.
If the battery gets low, and has to be jumped, or charged up quickly, it is best to replace it, or it will start causing electrical issues in the near future.
Good Luck

Update: the performance shop was successful repairing the issue a ripple test on the alternator was performed that indicated some interference from 3 coil packs with corrosion and some plug wires that were melted due to improper routing from the tuning shop prior that performed their modification and also a knock sensor wire was repaired have not had the service light return. Thanks again for the help
