Service bulletin 1HD-M8G2K-03

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

Tech Tips, TT459: TIRE PRESSURE MONITORING SYSTEM (TPMS). Both dealers and customers have raised questions regarding TPMS and how the system works. Additionally there have been warranty claims for tire pressure sensors that upon return have been tested as ?no trouble found?. The intention of this Tech Tip is to answer some of those questions, and reduce replacement of functioning tire pressure sensors.
