The small black wire at the negative terminal may have been damaged during a recent battery replacement.

This bulletin applies to 2014-2019 Chevy Corvette vehicles. During initial diagnosis, a technician may find a B1517 set.

If this code is set in any module, or even in multiple modules, technicians are to first inspect the battery cable connections.

In many cases, the small black wire that connects to the larger battery negative cable is loose or damaged. This may be the result of a recent battery change. Check the small black wire for looseness, poor rotation or disengagement from the terminal.
