Toyota Corolla Cross: Tire Pressure Monitor Transmitter ID 1 Missing Message (C214187-C214487)

Toyota Corolla Cross (2022-2024) Service Manual / Suspension / Tire Pressure Monitoring / Tire Pressure Warning System / Tire Pressure Monitor Transmitter ID 1 Missing Message (C214187-C214487)

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.

DTC No.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the tire pressure warning ECU and receiver, first use the GTS to record all of the current IDs and registered tires with transmitters of the tire pressure warning valve and transmitter registered to the tire pressure warning ECU and receiver.
  • It is necessary to perform initialization after registration of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU and/or one of the valve and transmitters has been replaced.

PROCEDURE

1.

CHECK FREQUENCY RECEIVING CONDITION

(a) Check that the following conditions are not met:

(1) Facilities or devices that use similar radio frequencies are located in the vicinity of the vehicle.

HINT:

If the vehicle is located in an area such as the one described above, the tire pressure warning light may illuminate after blinking for 1 minute due to interfering radio frequencies.

(2) Devices using similar radio frequencies are used in the vehicle.

HINT:

Radio transmissions may be interrupted due to the surroundings or devices installed by the user.

Result

Proceed to

There is no device or facility that uses radio waves of approximately the same frequency in the vicinity of the vehicle or inside the vehicle.
