    3. Press the unlock switch.
3.Push the OK button after "Keyless ID Registration was finished." is displayed.

4.Check number of the keyless IDs registered.

"Tire Pressure Sensor ID Registration" METHOD
1.Select "4tires ID Reg. (Change tire PRS.)" and start the tire pressure sensor ID registration.
2.
caution Register all tire pressure sensor IDs within twenty minutes.
"4 SNSR ID Registration Do you want to start? Note Finish ID Registration within 20 minutes." is displayed. Then, press "OK."
note If the ID code registration is not finished within 20 minutes, all the ID codes registered in the TPMS transmitter before will be erased. For this reason, the ID codes need to be registered again.
3.Decrease the tire pressure to 174 kPa (25.2 psi) or less by changing 20 kPa (2.9 psi) or more, and register the TPMS transmitter ID code of each wheel to WCM.
note
  • You can start out the operations from any TPMS transmitter. The tire pressure sensor ID registration has no order.
  • On completion of the TPMS transmitter ID code registration, the TPMS transmitter ID code is displayed on the scan tool screen.
  • Scan tool cannot identify which registered TPMS transmitter is used for each wheel. For this reason, write down the tire number for each wheel when the tire number and ID code is displayed on the scan tool during ID code registration.
  • It may take approximately one minute for the ID code to be displayed on the scan tool screen after the tire pressure is reduced.
  • If the ID code is not displayed, reduce the tire pressure another 20 kPa (2.9 psi) or more. If the ID code is not displayed yet, rotate the tire to displace the TPMS transmitter, and reduce the tire pressure 20 kPa (2.9 psi) or more again.
  • If the ID code cannot be registered for all the four wheels, the WCM may be faulty, thus replace the WCM.
  • If the ID code can be registered for one wheel or more, the TPMS transmitter in which the code cannot be registered may be faulty, thus replace that TPMS transmitter.
4."4 SNSR ID Registration Completed." is displayed. Then, select "OK."
note The TPMS indicator illuminates for tire pressure alarm.
5.After one minute or more has passed, correct the tire pressure for all wheels with ignition switch "ON".
6.Check the data list "Registered ID reception, Tire 1, 2, 3, 4" if "YES" is displayed for each tire. When "NO" is displayed, drive the vehicle for approximately 5 minutes, check the display again. If "NO" is still displayed, register the ID code again.

"TPMS transmitter check" METHOD
According to the following procedures, identify which registered TPMS transmitter corresponds to which wheel, and check the tire pressure and acceleration value of each TPMS transmitter.
1.Check the data list "Air Pressure, Tire1, 2, 3, 4" and write down the tire pressure for all wheels.
note The display at this time is the data received most recently.
2.Perform the following procedures for four wheels in order, identify the wheel by checking the tire pressure of each wheel.
(1) Change the pressure of tire for 20 kPa (2.9 psi) or more so that the TPMS transmitter sends the latest sensor data (The tire pressure can either be decreased or increased).
(2) Check the data list screen to determine which tire number corresponds to the wheel whose tire pressure has changed.
note
  • It may take approximately one minute that the data of tire pressure change is displayed on the scan tool screen.
  • If the data of tire pressure change is not displayed on the scan tool screen, the most possible cause is that the radio wave sent from the TPMS transmitter cannot be received. In this case, the radio wave may be received by performing the procedures from (1) again after turning the tire to change the TPMS transmitter position. If the tire pressure change is still not displayed on the scan tool screen, the TPMS transmitter in which the ID code is not registered may be installed, or the TPMS transmitter may be faulty. Therefore, perform ID code registration or replace the TPMS transmitter according to the instructions of troubleshooting for DTCs. (At this time, do not register the ID codes or replace the TPMS transmitter.)
3.Check the tire pressure or acceleration value shown in the screen (if needed).
4.After checking by the tire pressure change, adjust the checked tire pressure to the proper value.

"Tire Pressure Sensor ID Check" METHOD
1.Select "Tire Pressure Sensor ID Check".
2.Check the registered TPMS transmitter IDs on the scan tool screen.
