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.

Resetting the PAX System Warning When a tire goes flat or, is very low on pressure, the multi-information display will show “PAX SYSTEM WARNING, RUN FLAT DRIVING.” After the tire is repaired or replaced, you must reset the warning indicator (and the mileage counter that supports it), no matter how far the vehicle was driven in the run flat mode. 1. To put the gauge control module into the self-diagnostic mode: Turn the headlight switch to ON. Press and hold the SELECT/RESET (instrument panel brightness) knob. Turn the ignition switch to ON (II). Within 5 seconds, turn the headlights to AUTO, then to ON, and then to AUTO again. Within 5 seconds, release the SELECT/RESET knob, then push and release the knob three times. 2. Once the gauge control module is in the self-diagnostic mode, press and hold the INFO button on the steering wheel for 5 seconds to get to the CUSTOMIZE MENU. 3. Use the INFO button to scroll through to the PAX RESET screen, then press the SEL/RESET button on the steering wheel. 4. Use the INFO button to scroll to the appropriate wheel, and then press the SEL/RESET button on the steering wheel to reset the PAX warning system display. The screen should read PAX RESET COMPLETED. Repeat this step for each wheel that needs to be reset. 5. Use the INFO button to scroll through to EXIT, then press the SEL/RESET button. 6. Turn the ignition switch to LOCK (0) to exit the self-diagnostic mode.

Models ‘04 – ‘05 Highlander, RAV4, Sienna, & Solara, ‘05 Scion tC This service bulletin provides the proper procedures for normal maintenance re- initialization of the indirect Tire Pressure Warning System (TPWS). When performing service that requires tire rotation or tire replacement, suspension component replacement or alignments, the Tire Pressure Warning System must be re-initialized. During initialization, the Tire Pressure Warning System, located within the ABS or Skid Control ECU, learns the tire sizes from rotational speeds and resonance frequencies.
