Circuit 15 has an open circuit




i did a quick search but couldnt really find anything related nor any useful info that could help.
a few days ago i went to work just like i usually do in the morning , and after maybe 3 minutes if driving , i lost power , exhaust didn't sound the same (hard to explain but you could tell and hear that something is wrong) , i got a CEL but without any notification on cluster display , just lost power and an orange CEL in cluster.
so i immediately pulled into a parking. Restarted the car and everything is good ever since.
today i got my hands on a Icar soft OBD 2 scanner and was able to pull the code... which said A12c (not sure if its the actual code or just a scanners random number) circuit 15 has an open circuit , which i thought was related to the problem i had the other day.
any thoughts or info about this code?
thank you
