Repair Instruction: Initialization

HINT:

The VIN is a 17-digit alphanumeric vehicle identification number. The Techstream is required to register the VIN.

1. Description

   HINT:

   This registration section consists of two parts: Read VIN and Write VIN.

   1. Read VIN: 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.
   2. Write VIN: 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 procedure.
2. Read VIN
   1. Confirm the vehicle VIN.
   2. Connect the Techstream to the DLC3.
   3. Turn the ignition switch to ON.
   4. Turn the Techstream on.
   5. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Read.
3. Write VIN
   1. Confirm the vehicle VIN.
   2. Connect the Techstream to the DLC3.
   3. Turn the ignition switch to ON.
   4. Turn the Techstream on.
   5. Enter the following menus: Powertrain / Engine and ECT / Utility / VIN / VIN Write.

HINT:

• The ID codes are the same as recognition codes for the wireless transmitter and the engine immobilizer function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobilizer function to be operated.
• Code registration is necessary when the certification ECU (smart key ECU assembly), ID code box (immobilizer code ECU), steering lock ECU, or key is replaced with a new one.

1. Vehicles with the smart key system do not have a key slot. Therefore, hold the key close to the engine switch to register the key, as shown in the illustration.

1. The following table shows ECU replacement and key registration procedures for cases in which a malfunctioning ECU has been identified through the troubleshooting of the smart key system.

   HINT:

   • The following procedures can be performed:
     • New key ID registration
     • Additional key ID registration
     • Key ID erasure
     • All key ID erasure
     • ECU code registration
   • If the customer has not brought all the registered keys, replacement of the ID code box (immobilizer code ECU) is also required.
   • A maximum of 4 keys can be registered.

1. New key code registration (Procedure "A"):
   NOTE: Make sure that no key codes are registered in the transponder key ECU assembly.

   HINT:

   • 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 assembly 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.
   • When a new transponder key ECU assembly is installed, key codes must be registered in the transponder key ECU assembly.

1. Additional registration (Procedure "B"):

   HINT:

   • A maximum of 5 key codes and 3 sub-key codes can be registered.
   • Registration mode will end if any step is not completed within the specified time.
   • When the ignition cylinder or the 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.
   NOTE: When the ignition key cylinder has been replaced, locking and unlocking doors are possible with the new master key's transmitter module (removed from the original master key). However, the new master key will not be able to lock and unlock doors through the door key cylinder. Keep the original master key.

HINT:

The ECM memorizes the condition that the ECT controls the automatic transaxle assembly and engine assembly according to those characteristics. Therefore, when the automatic transaxle 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.

1. Turn the ignition switch off.
2. Connect the Techstream to the DLC3.
3. Turn the ignition switch to ON and the Techstream main switch on.
4. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory. Then, press "Next".
   CAUTION: After performing the RESET MEMORY, be sure to perform the ROAD TEST (See ROAD TEST ) described earlier.

   HINT:

   The ECM is learned by performing the ROAD TEST.

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.

1. Before registration
   1. When replacing the tire pressure warning ECU:
      • 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 valve and transmitters (See TIRE PRESSURE WARNING SYSTEM ).
   2. When replacing a tire pressure warning valve and transmitter:
      • Take note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
        Fig 5: Identifying Tire Pressure Warning Valve And Transmitter

        Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      NOTE:

      • 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.
      • The ID registration must be performed for all tire pressure warning valve and transmitters. Check the Data List, replace the exchanged ID with a new ID, and make a new DATA LIST of all 4 tires for the vehicle.

1. Set the all tire pressure to the specified value (See TIRE PRESSURE WARNING SYSTEM ).
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 / Utility / ID Registration.
7. Perform the following procedure displayed on the screen.
8. 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 data of tire pressure of all tires are displayed on the Techstream.
      NOTE:

      • It takes about 2 or 3 minutes to display the updated 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.
      • If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
      • If normal pressure values are displayed, the IDs have been registration 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 (Transmitter ID not Received) is set 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 radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.

1. Adjust all tire (except spare tire) to the standard tire inflation pressure, as indicated on the tire and loading information label on the vehicle.
2. Turn the ignition switch to ON.
3. Push and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.

4. Turn the ignition switch off.
5. Connect the Techstream to the DLC3.
6. Turn the ignition switch to ON.
7. Turn the Techstream on.
8. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
9. Check that the initialization has been completed.
10. Confirm that the tire pressure data of all wheels are displayed on the Techstream.
    NOTE:

    • The initialization is normally completed within 2 or 3 minutes.
    • If the initialization has not been completed successfully, DTC C2177/77 is set after a vehicle speed 8 km/h (5 mph) or more continues for 20 minutes or more.
    • The initialization can be terminated by connecting terminals TC and CG of the DLC3.
