I just got back from the Studio and there was a flash update but they didn't tell me any information about it. Work Order just specified RRT-15-010.

My 2015 POP with 4100 miles threw the same code. It was read by the local Chrysler dealer for no charge. I disconnected the battery for a half hour, and the CEL didn't com on for several days. Then it came on again. I drove it for a day with the CEL light on. Then, for some reason the CEL went off and has stayed off.

Maybe this will fix my problem.
