This bulletin applies to 2014-2019 Chevy Corvette vehicles. While the vehicle may be in your shop for any number of reasons, if DTC B1517 is found set in any module, or even multiple modules, first inspect the battery cable connections.

In many cases, the small black wire that connects to the larger battery negative cable may be loose or damaged.

If the vehicle history is reviewed, or if the customer is questioned, it will usually be found that a battery was recently replaced. This may have been done by a technician (or owner) who was unfamiliar with the vehicle.

The small black wire may be loose, rotated or pulled out of the terminal. Any loose connection or damage to this circuit may cause a B1517, especially with symptom 5A.
