Code C2112 Scion Description

The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressures. The measured values are transmitted to the Tire Pressure Warning ECU and receiver in the vehicle as radio waves. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air 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 Diagnostic Trouble Code (DTC) when the tire pressure warning valve and transmitter stop transmitting signals. The signals can be forcibly transmitted by releasing the tire pressure rapidly. The stored DTC is cleared when signal transmission resumes.
