This bulletin may apply to vehicles still within the new model launch repair authorization period!

Center (TAC) per the repair authorization. Reference this TSB in the first line of the TAC case.

Make sure the vehicle is online and has a valid time signal (sufficient satellite reception).

Ensure the ignition was not activated using a digital key.
