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.

Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm², 5.8 psi) within 30 seconds.

Check that each "ID Tire Inflation Pressure" value displayed on the GTS has changed.

OK:: Each "ID Tire Inflation Pressure" value displayed on the GTS changed to the actual tire inflation pressure value.

NOTICE:: ·

It may take a few minutes until the values are displayed.

·

When an "ID Tire Inflation Pressure" value has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the value.

ii.

After confirming that all of the tire "ID Tire Inflation Pressure" values displayed on the GTS have changed, set the tire pressure to the appropriate specified values.

HINT:: If an "ID Tire Inflation Pressure" value displayed on the GTS has not changed after rechecking, inspect for another problem.; Click hereSuspension>TIRE PRESSURE MONITORING>TIRE PRESSURE WARNING SYSTEM (for Gasoline Model (for Type A))>C2121202304,202502,_53,_080780,_0393955,RM100000002B0EY,C2121
