If I'm not touching car for a day my battery goes flat. In car seems everything working. Any suggestions of what is causing this and explanation of the fault code? I know that ROSS TECH says that is CCM Module faulty and check wiring. But maybe some of you have had the same issue and find some common problem. Thank you for any help.
