Official summary

This is a Technical Journal: It may happen that after a software download, the TPMS light is flashing and DTC VDDM-U24004A, "ECU Software. System internal failures" is set. This is due to that the I-TPMS function in VDDM has not been initialized.

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.
