Some owners of 2017-2018 Chevy Corvette vehicles may comment about a “Service Rear Differential” message displayed on the DIC (driver information center).

The condition may be caused by a software anomaly in the rear differential clutch control module (RDCCM). The module must be updated to the latest software calibration available. Refer to K47 Rear Differential Clutch Control Module Programming and Setup in the service manual.
