DTC C2126/26 Transmitter ID not Received in Main Mode


DESCRIPTION

After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then illuminates.
When the tire pressure warning ECU and receiver successfully receives radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.

DTC No.
DTC Detection Condition
Trouble Area
C2126/26
After ID registration is completed, ECU does not receive radio waves from transmitters whose IDs are stored in ECU.
  1. ID registration failure
  2. Tire pressure warning valve and transmitter
  3. Tire pressure warning antenna (for Rear Side)
  4. Tire pressure warning antenna (for Front Side)
  5. Harness or connector
  6. Tire pressure warning ECU and receiver
NOTICE:
For the ID switching function, (Main) is displayed on the DTC screen for the DTCs even when the 2nd set of tires is selected.
HINT:
The purpose of this DTC is to help prevent delivering a vehicle that has incorrectly registered IDs. After all IDs are registered, DTC C2126/26 is detected and the tire pressure warning light blinks for 1 minute and then illuminates. If the tire pressure warning light does not turn off after a little while, IDs may be incorrectly registered.

  1. Check the Data List.

    NOTICE:
    1. It may take a few minutes to display the updated tire pressure data.
    2. When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the data.
    3. Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.
