DESCRIPTION The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressure of each wheel. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured tire pressure values with the tire pressure threshold. When the measured tire pressure value is less than this threshold, the warning light in the combination meter assembly illuminates. The tire pressure warning ECU and receiver stores a DTC when the tire pressure warning valve and transmitter stops transmitting signals. The signals can be forcibly transmitted by releasing the tire pressure rapidly. The stored DTCs are cleared when signal transmission resumes.
HINT: It is necessary to perform the following procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC. WIRING DIAGRAM  PROCEDURE
(a) Set the tire pressure to the specified value. Click here
(b) Turn the engine switch off. (c) Connect the Techstream to the DLC3. (d) Turn the engine switch on (IG). (e) Turn the Techstream on. (f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List. (g) Read the Data List according to the display on the Techstream. Chassis > Tire Pressure Monitor > Data List
HINT: *1: It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121 to C2124. Click here
(h) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds. (1) Check that each "ID Tire Inflation Pressure" value displayed on the Techstream has changed. OK: Each "ID Tire Inflation Pressure" value displayed on the Techstream changed to the actual tire inflation pressure value. NOTICE:
(2) After confirming that all of the tire "ID Tire Inflation Pressure" values displayed on the Techstream have changed, set the tire pressure to the appropriate specified values. HINT: If an "ID Tire Inflation Pressure" value displayed on the Techstream has not changed after rechecking, inspect for another problem. Click here
