Service bulletin L-SB-0033-13

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

2014 model year RX 350 and RX 450h vehicles are equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (except the spare tire) has a tire pressure warning valve/sensor that measures tire pressure data. The data is transmitted to the Tire Pressure Warning System antenna/receiver and then to the Tire Pressure Warning System ECU. During Pre-Delivery Service (PDS), the tire pressure warning valves/sensors must be activated for Japan-built vehicles by following the activation procedure in this bulletin. NAP-built vehicles do NOT require activation, but both Japan-built (VINs start with ?J?) and NAP-built (VINs start with ?2?) vehicles require the TPWS to be initialized by following the initialization procedure in this bulletin.
