April 5, 2026: LEMON Manuals is launched! Read the announcement.

Inspection Procedure

NOTE:
  • When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using Techstream and write them down before removal.
  • It is necessary to perform INITIALIZATION  after REGISTRATION  of the transmitter IDs into the tire pressure warning ECU if the ECU and/or any of the valve and transmitters have been replaced.
  1. READ OUTPUT DTC (DTC C2173/73) 
    1. Turn the ignition switch off.
    2. Connect Techstream to the DLC3.
    3. Turn the ignition switch on (IG) and turn the tester on.
    4. Enter the following menus: Chassis / Tire Pressure Monitor / Trouble Codes.
    5. Read the DTCs.

    NOTE: When DTC C2173/73 is output, troubleshoot that DTC first. Then troubleshoot DTCs C2121/21 to C2124/24.

    B:  GO TO DTC C2173/73 

    A: Go to next step 

  2. CHECK FREQUENCY RECEIVING CONDITION 
    1. Check that the vehicle is located in an area such as described below:
      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 described above, the tire pressure warning light may turn on only in a particular area due to interfering radio frequencies.

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

        OK: Facilities, or devices that use similar radio frequencies are not located in the vicinity of the vehicle. 

        HINT:

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

    NG: CHECK IF ANY DEVICE IS INSTALLED BY USER 

    OK: Go to next step 

  3. IDENTIFY TRANSMITTER CORRESPONDING TO DTC 
    1. Set the tire pressure to the appropriate specified values (See PRECAUTION  ).
    2. Turn the ignition switch off.
    3. Connect Techstream to the DLC3.
    4. Turn the ignition switch on (IG) and turn the tester on.
    5. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

    8. Check the DATA LIST.
      NOTE:
      • It takes about 2 or 3 minutes to display the updated tire pressure data.
      • 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°. Then rapidly release the tire pressure and recheck the data.
      • Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.
    9. After confirming that the "ID Tire Inflation Pressure" data for one tire (ID1 to ID5) has changed, repeat this procedure one by one. Identify the transmitter that corresponds to the DTC.
