DTC C2141-87: Tire Pressure Monitor Transmitter ID 1 Missing Message; DTC C2142-87: Tire Pressure Monitor Transmitter ID 2 Missing Message; DTC C2143-87: Tire Pressure Monitor Transmitter ID 3 Missing Message; DTC C2144-87: Tire Pressure Monitor Transmitter ID 4 Missing Message; DTC C2145-87: Tire Pressure Monitor Transmitter ID 5 Missing Message [11/2023 - 11/2024]: 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 valve and transmitters constantly send radio waves to the tire pressure warning ECU and receiver.

Under the conditions below, the tire pressure warning ECU and receiver is unable to receive the signals from the tire pressure warning valve and transmitters, and a DTC is stored.

• Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.
• Devices using similar radio frequencies are used in the vehicle.
• The ID of a tire pressure warning valve and transmitter is mistyped during registration.
• A tire, wheel and/or transmitter from a different vehicle is installed.
