PROCEDURES NECESSARY WHEN ECU OR OTHER PARTS ARE REPLACED
2. DESCRIPTION
HINT
This registration section consists of two parts: Read VIN and Write VIN.
(a) 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's ECM, are the same.
(b) 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.
3. READ VIN
(a) Confirm the vehicle VIN.
(b) Connect Techstream to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn the tester ON.
(e) Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.
4. WRITE VIN
(a) Confirm the vehicle VIN.
(b) Connect Techstream to the DLC3.
(c) Turn the ignition switch ON.
(d) Turn the tester ON.
(e) Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Write.
5. RESET MEMORY
NOTICE:
* Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assembly, engine assembly or ECM.
* 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, engine assembly, or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON and push the tester switch ON.
(c) Enter the following menus:
(1) Select: 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.
6. DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.
Prepare all transmitter ID data before starting registration.
(a) 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 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 valves and transmitters.
(2) In case of tire pressure warning valve and transmitter replacement:
Take a note of the 8 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 on the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.

17. NEW KEY REGISTRATION (PROCEDURE "B")
(a) New key code registration
HINT
* This mode operates normally when no key codes are registered in the transponder key ECU.
* When a new transponder key ECU is installed, key codes must be registered in the transponder key ECU.
* In this mode, a maximum of 3 key codes for 2 master keys and 1 sub-key can be registered. The master keys and sub-key can be registered in any order because the transponder key ECU can distinguish between different types of keys.
* New key codes must be registered with the battery connected. The ignition switch can be either ON or OFF.
(b) End the new key code registration mode (when not using Techstream)
HINT
The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key has been registered.
(1) Turn the ignition switch ON and OFF 5 times within 10 seconds using a master key that has already been registered.
(c) End the new key code registration mode (when using Techstream)
HINT
The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key has been registered.
(1) Insert the key into the ignition key cylinder and turn the Techstream ON.
(2) Follow the instructions on the Techstream screen to end the new key code registration mode.
HINT
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
* If the new key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister an already registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown below.
18. REGISTRATION OF ADDITIONAL KEY (PROCEDURE "A")
(a) Additional key code registration
HINT
* At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
* In this mode, a maximum of 5 master key codes and 3 sub-key codes can be registered.
* This mode ends if each step is not completed within the specified time.
* When the ignition key cylinder or the ignition key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.
NOTICE:
When only the ignition key cylinder has been replaced, the new key cannot be used to lock or unlock doors. Therefore, keep the original key for locking and unlocking doors in order to avoid being locked out of the vehicle if the transmitter battery becomes depleted.
HINT
* A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the screen of the Techstream.
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
* If the additional key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister a previously registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown in procedure "B".
19. ERASURE OF KEY CODE (PROCEDURE "D")
HINT
All key codes are erased except for the master key which is used for erasing the key codes. In order to use a key whose code has been erased, a new key code must be registered.
(a) Erasure all key codes except master key
HINT
* At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
* Make sure the inserted key is a registered master key.
(b) Erasure all of key codes
HINT
* This mode performs normally, when at least one key codes must be registered in the transponder key ECU.
* Insertion key is either registered key or unregistered key.
HINT
* A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the screen of the Techstream.
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
20. ECU - ECM COMMUNICATION ID REGISTRATION (PROCEDURE "C")
