DTC C2141-96: Tire Pressure Monitor Transmitter ID 1 Component Internal Failure; DTC C2142-96: Tire Pressure Monitor Transmitter ID 2 Component Internal Failure; DTC C2143-96: Tire Pressure Monitor Transmitter ID 3 Component Internal Failure; DTC C2144-96: Tire Pressure Monitor Transmitter ID 4 Component Internal Failure; DTC C2145-96: Tire Pressure Monitor Transmitter ID 5 Component Internal Failure [11/2023 - ]: 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.

When the internal circuit of a tire pressure warning valve and transmitter is malfunctioning, one of these DTCs is output.

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.
