Brand Quality would like to remind dealers that oil leak dye is not compatible with the M1L Corvette transmission and should not be used in place of trace powder. Document ID: 5395398 states:

Failure to use the recommended trace leak powder may cause internal transmission component damage

C8 Corvette (2020+) Instrument Cluster Programming

Dealers may have difficultly to program the Instrument Panel Cluster (IPC) in these vehicles.
This may be the result of completing Service Update N202314260, or it may be just a regular programming procedure for another issue.

If there is a concern where the Graphics Programming portion of the IPC will not complete, please make sure that there are not any communication issues or DTCs set that would apply to a different diagnostic path.
Also make sure that the ignition is in the OFF power mode and that an MDI 2 is being used for programming. In addition, verify the battery SOC is sufficient for programming.

If the programming procedure still will not complete, please contact Techline for additional programming support
