Official summary
ServiceNews Article - It has been found that when replacing the PCM/ECM, the Dynamic Drive mode images - normally displayed on the center display - no longer appear. In order to prevent this, make sure that the software version on the infotainment control unit reads D.1.5.1 or higher. If the version is not up to date, you must complete the update by using the OTA function or via USB.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
