PROCEDURES NECESSARY WHEN ECU OR OTHER PARTS ARE REPLACED
2. REGISTRATION RELATED TO SFI SYSTEM
(a) DESCRIPTION
HINT
This registration section consists of two parts: Read VIN and Write VIN.
(1) Read VIN: Explains the VIN reading process in a flowchart. This process allows the VIN stored in the ECM to be read in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle ECM, are the same.
(2) Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is changed, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
(b) READ VIN
(1) Confirm the vehicle VIN.
(2) Connect the Techstream to the DLC3.
(3) Turn the engine switch on (IG).
(4) Turn the Techstream on.
(5) Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.
(c) WRITE VIN
(1) Confirm the vehicle VIN.
(2) Connect the Techstream to the DLC3.
(3) Turn the engine switch on (IG).
(4) Turn the Techstream on.
(5) Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Write.
3. INITIALIZATION RELATED TO AUTOMATIC TRANSMISSION SYSTEM
(a) RESET MEMORY
NOTICE:
* Perform the Reset Memory (AT initialization) when replacing the automatic transmission assembly, valve body assembly or any of the shift solenoid valves.
* The Reset Memory can be performed only with the Techstream.
HINT
The ECM memorizes the control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, valve body assembly or any of the shift solenoid valves has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
(1) Connect the Techstream to the DLC3.
(2) Turn the engine switch on (IG).
(3) Turn the Techstream on.
(4) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.
NOTICE:
After performing the Reset Memory, be sure to perform the Road Test described earlier.
HINT
The ECM learns through the Road Test.
4. ADJUSTMENT FOR AUTOMATIC TRANSMISSION FLUID

6. REGISTRATION RELATED TO TIRE PRESSURE WARNING SYSTEM
(a) DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing a tire pressure warning valve and transmitter and/or the tire pressure warning ECU:
Prepare all transmitter ID data before starting registration.
(1) Before registration
1 In case of tire pressure warning ECU replacement:
* Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
* 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.
2 In case of tire pressure warning valve and transmitter replacement:
* Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
NOTICE:
The transmitter ID is written on the tire pressure warning valve and transmitter. It will be unable to be read after installing the tire pressure warning valve and transmitter to the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.
(b) REGISTER TRANSMITTER ID (USING TECHSTREAM)
(1) Set the air pressure of all tires to the specified value(s).
(2) Turn the engine switch off.
(3) Connect the Techstream to the DLC3.
(4) Turn the engine switch on (IG) and the Techstream on.
(5) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
(6) Perform the procedures displayed on the Techstream.
HINT
* The previously registered IDs will be cleared from the memory when the registration is completed.
* Registration can be performed during initialization. However, the initialization will be canceled when the registration is started.
* If this step is not completed within 300 seconds, this mode will be canceled.
(7) Confirmation of transmitter ID registration:
1 Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
2 Read the "ID Tire Inflation Pressure" values.
3 Confirm that the tire pressure data of all tires (including the spare tire) is displayed on the Techstream screen.
NOTICE:
* It may take up to about 2 or 3 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 C2125/25.
* 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.
* The tire pressure information reception condition can also be confirmed through the multi-information display tire pressure display screen.
* 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 and receiver successfully receives information from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.
7. INITIALIZATION RELATED TO TIRE PRESSURE WARNING SYSTEM
(a) DESCRIPTION OF INITIALIZATION
