    REPLACE CORRESPONDING TIRE PRESSURE WARNING VALVE AND TRANSMITTER. Refer to  REMOVAL [03/2017 - 09/2019] 

  3. IDENTIFY TRANSMITTER CORRESPONDING TO DTC (TIRE POSITION) 
    1. Set the tire pressure to the specified value.

      Refer to INSPECTION [03/2017 - 06/2017]

    2. Turn the ignition switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the ignition switch to ON.
    5. Turn the Techstream on.
    6. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
    7. Display the "ID Tire Inflation Pressure" value for each wheel using the Techstream.

      Chassis > Tire Pressure Monitor > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      ID 1 Tire Inflation Pressure ID1 tire inflation pressure min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2 , 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2 , 0 psi)

      max.: Absolute pressure (abs) / 480 kPa (4.9 kgf/cm2 , 70 psi), Relative pressure (Gauge) / 380 kPa (3.9 kgf/cm2 , 55 psi)      		 Actual tire inflation pressure If N/A is displayed, data has not been received.*1

      HINT: 

      *1: It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.

      Refer to DTC C2121/21: No Signal from Transmitter ID1; DTC C2122/22: No Signal from Transmitter ID2; DTC C2123/23: No Signal from Transmitter ID3; DTC C2124/24: No Signal from Transmitter ID4; DTC C2181/81: Transmitter ID1 not Received (Test Mode DTC); DTC C2182/82: Transmitter ID2 not Received (Test Mode DTC); DTC C2183/83: Transmitter ID3 not Received (Test Mode DTC); DTC C2184/84: Transmitter ID4 not Received (Test Mode DTC) [03/2017 - 06/2017]

      Chassis > Tire Pressure Monitor > Data List 

      Tester Display
      ID 1 Tire Inflation Pressure
      ID 2 Tire Inflation Pressure
      ID 3 Tire Inflation Pressure
      ID 4 Tire Inflation Pressure
    8. Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kg/cm2 , 5.8 psi) within 30 seconds. If the "ID Tire Inflation Pressure" value displayed on the Techstream does not change, the tire pressure warning valve and transmitter corresponding to the unchanged "ID Tire Inflation Pressure" value was the cause of the output DTC.

      HINT: 

      • Identify the malfunctioning tire pressure warning valve and transmitter by repeatedly decreasing the tire pressure for each tire.
      • Record which "ID Tire Inflation Pressure" value corresponds to each tire.
    9. Check the Data List.
      NOTE:
      • It may take a few minutes until the values are displayed.
      • When an "ID Tire Inflation Pressure" value 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 value.
      • Record the transmitter IDs and positions of transmitters that are normal.
    10. After confirming that the "ID Tire Inflation Pressure" value for one tire has changed, repeat this procedure one by one. Identify the transmitter that corresponds to the DTC.
    11. When all of the "ID Tire Inflation Pressure" values have changed, identify the malfunctioning tire pressure warning valve and transmitter using the recorded ID numbers and output DTCs.
