TSB: 2017 model year LX 570 vehicles are equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (including the spare tire) has a tire pressure warning valve/sensor that measures tire pressure. The data is transmitted to the Tire Pressure Warning System antenna/receiver and then to the Tire Pressure Warning System ECU. After adjusting ALL tires to the standard air pressure, perform initialization of the Tire Pressure Warning System during Pre-Delivery Service (PDS) according to the procedure outlined below.
