Official summary
Complaint Red TPMS warning message in instrument cluster with "Check Tire" despite correctly set tire inflation pressures (see attachment for reference picture). Cause Excessively high minimum tire pressure values may have been stored in the tire pressure monitoring system control unit (N88). The minimum tire pressure value is stored in the control unit in order to prevent excessively low tire inflation pressures from being set and taught in. Remedy Recommission (initial startup) tire pressure monitoring system control unit (N88). This ensures new minimum tire pressure values are stored.

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.
