    Please help c1241 code

    ✳️✳️ Update the local garage told me it HV traction battery problem. And he told me he had recalibrate the battery because the cells were not even, some 80 % and some 50%. He did this by using a snap on scanner only. And it took approximately 30 minutes. Is this possible I paid him for the work.



    As I drove out of the garage. The braking system light re appeared. Thanks for looking everyone. IMG_1240.jpeg IMG_1229.jpeg

    I think I would not return to that garage. C1241 is not about the traction battery, and there is no traction battery 'recalibration' that balances the modules in half an hour using only a scan tool.

    He can insist all he wants; there's no scan tool function to 'balance' a traction battery that I know of. Not in half an hour, not in an hour.

    So far, I can't say what "needs replacing", if anything. It sounds like you have a C1241 code. You can search for C1241 on this page, and you'll get the basic idea what things can cause it and where to start looking:

    Fixing or replacing anything comes after finding the cause of the problem.
