Reset Procedure
REGISTRATION
1. BEFORE REGISTRATION
NOTICE:
The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire onto the wheel. Therefore, make a note of the transmitter ID before installing the tire.
(a) In case of tire pressure warning ECU replacement:
(1) Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
(2) If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.
(b) In case of tire pressure warning valve and transmitter replacement:
(1) Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

2. REGISTER TRANSMITTER ID (USING THE TECHSTREAM)
HINT
* The previously registered IDs will be cleared from memory when the registration is completed.
* If the ID registration step is not completed within 300 seconds, ID registration will be canceled.
(a) Set the air pressure of all tires to the specified value(s) Component Tests and General Diagnostics.
(b) Turn the power switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the power switch on (IG) and the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
(f) Perform the procedure displayed on the Techstream.
3. CONFIRMATION OF TRANSMITTER ID REGISTRATION
NOTICE:
* It may take up to a few minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 Transmitter ID4 not Received (Test Mode DTC) - Tire Pressure Monitoring.
* If the IDs have not been registered, DTC C2171/71 is stored in the tire pressure warning ECU after 3 minutes or more.
* If normal pressure values are displayed, the IDs have been registered correctly.
* If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
* After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.
(a) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(b) Read the "ID Tire Inflation Pressure" values.
(c) Confirm that the tire pressure data of all tires (except the spare tire) is displayed on the Techstream screen.
INITIALIZATION
NOTICE:
* Initialization can be confirmed through the tire pressure warning light.
* The order in which the data is received is random.
* If the signals from all the wheels are received, initialization is completed.
* Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures Data List / Active Test.
* Initialization is normally completed within a few minutes.
* It may take up to 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 Transmitter ID4 not Received (Test Mode DTC) - Tire Pressure Monitoring.
* If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
* During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
* Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.
