Introduction The 2011 model year Camry is 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 TSB. NAP-built vehicles do not require activation, but both Japan-built and NAP-built vehicles require the TPWS to be initialized by following the initialization procedure in this TSB. Initialization Procedure NOTE Perform the following initialization procedure for BOTH NAP-built and Japan-built vehicles. 1. Cycle the ignition switch to the “IG–ON” mode and connect TIS techstream. 2. Adjust all tires (except the spare tire) to the standard tire in?ation pressure, as indicated on the Tire and Loading Information label located inside the driver’s door jamb and con?rm that the Low Tire Pressure Warning Light is OFF. NOTE To adjust tire pressure correctly when outside temperature is signi?cantly colder or warmer than shop temperature. Follow the procedures outlined in the Tire In?ation Pressure Compensation and Adjustment service bulletin (T-SB-0345-08). NOTE Adjust the tire pressure when the tires are cold. NAP-built: Remove the ID number labels that are attached to each wheel and discard.
