DTC C2111/11: Transmitter ID1 Operation Stop; DTC C2112/12: Transmitter ID2 Operation Stop; DTC C2113/13: Transmitter ID3 Operation Stop; DTC C2114/14: Transmitter ID4 Operation Stop: Description

The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the air pressure of the tires. The measured values are transmitted to the tire pressure warning antenna on the body as radio waves and then sent to the tire pressure warning ECU and receiver. The ECU and receiver 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 comes on. The tire pressure warning ECU and receiver stores a DTC when a tire pressure warning valve and transmitter stops transmitting signals. At this time, forcibly transmit the signals by releasing the tire pressure rapidly. The stored DTC is cleared when the signal transmission is resumed.

HINT: 

It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.
