Service bulletin LI40.15-P-079038

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
