Replaced CLC battery with a brand new one before annual pressure test as we always do. Performed test and everything was fine, car running perfect. Killed power to check an issue with battery lowering, turned power back on and complete program dump. Reloaded using the World tool like we have done a hundred other times, did learn run, everything works as it should but no hall calls. Laptop sees it when you push a call but car will not respond to hall calls.
