Function Description

1. Transponder Key Type

Before any Immobilizer functions are performed, verify the type of transponder key that you are attempting to use for the service operation. Some functions may only be performed with a registered Master Key.

2. Transponder Code Registration

This function allows the registration of additional transponder keys (Master or Sub) using a registered Master Key.

3. Transponder Code Erasure

This function allows the user to erase all the transponder keys except the registered Master Key used during this function.

4. Transponder ECU Reset

This function allows the registration of a new Master Key even if all original Master Keys are lost. Once the Immobilizer system is reset, all previous registered keys will be erased.

5. Transponder ECU Replacement

When the Transponder ECU is replaced, the transponder keys must be registered to the new ECU, auto registration closed, and ECU communication completed.

6. Engine ECU Replacement

When the Engine ECU is replaced, ECU communication must be completed to synchronize an encrypted security code between the engine and Transponder ECUs.

1. Transponder Key Type

Before any Immobilizer functions are performed, verify the type of transponder key that you are attempting to use for the service operation. Some functions may only be performed with a registered Master Key.

A. Insert the current key into the ignition cylinder and turn to the ON position.

HINT: The Immobilizer key blanks for the models listed in this TSB are preconfigured as Master or Sub Keys. Master Key blanks cannot be registered as Sub Keys nor can Sub Key blanks be registered as Master Keys. Also, the flat key is now enabled as a full function Master Key that must be registered.








B. Follow the screen flow in Figure 1 to determine the key type.

C. Key type and registration status will be indicated on the Immobilizer data list (Figure 1, screen E).

^ MATCH" = The key in the ignition cylinder matches this key type.

^ NO MATCH" = The key in the ignition cylinder does NOT match this key type.


2. Transponder Code Registration

This function allows the normal registration of additional transponder keys (Master or Sub) using a registered Master Key.

NOTE: This function requires the use of one registered Master Key. The use of a Sub Key will NOT complete Transponder Code Registration. Attempting registration of additional keys with only a Sub Key will result in errors and incomplete registration.








HINT: The Immobilizer key blanks for the models listed in this TSB are preconfigured as Master or Sub Keys. Master Key blanks cannot be registered as Sub Keys nor can Sub Key blanks be registered as Master Keys. Also, the flat key is now enabled as a full function Master Key that must be registered.

A. Insert a registered Master Key into the ignition cylinder and turn to the ON position.








B. Follow the screen flow in Figure 2 to register new Master or Sub keys. It is possible to register up to 5 Master Keys and 3 Sub Keys.

C. Be sure to follow the instructions on key insertion, ignition ON/OFF and key removal exactly as described on the Diagnostic Tester.

3. Transponder Code Erasure

This function allows the user to erase all the transponder keys except the registered Master Key used during this function.

NOTE: This function requires the use of one registered Master Key. The use of a Sub Key will NOT complete Transponder Code Erasure.

A. Insert a registered Master Key into the ignition cylinder and turn to the ON position.









B. Follow the screen flow in Figure 3 shown to erase all Master or Sub keys, except the registered Master Key used for this procedure.

4. Transponder ECU Reset

This function allows the registration of a new Master Key even if all original Master Keys are lost. Once the Immobilizer system is reset, all previous registered keys will be erased. Use a new transponder Master Key to complete Transponder ECU Reset.


Immobilizer Reset

The Immobilizer Reset function is a 4-step process:

A. Using the Diagnostic Tester, retrieve a "Seed Number" through the OBD/MOBD Immobilizer function.

^ A "Seed Number" is a unique number provided by the Diagnostic Tester and validated at TMS in order to return a Passcode.


B. Using the TIS (Technical Information System) workstation, select Immobilizer Reset, and complete the request form to retrieve a "Passcode Number."

^ A "Passcode Number" is a unique number required by the Diagnostic Tester to reset the ECU allowing it to accept a new Master Key.


C. Enter the "Passcode Number" received from TIS into the Diagnostic Tester, register any additional customer keys, and close auto registration mode.

D. Confirm successful Immobilizer reset and new Master Key registration.

A. Connect the Diagnostic Tester to DLC3 and turn ignition ON.

a. Using the Diagnostic Tester, retrieve a "Seed Number" through the OBD/MOBD Immobilizer function.









b. Follow each step outlined in Figure 4.








B. Using the TIS (Technical Information System) workstation, select Immobilizer Reset, and complete the request form to retrieve a "Passcode Number."

a. Click on Diagnostics.

b. Click on Immobilizer Reset.









c. Read the instructions on the screen and click on Continue. (See Figure 6)








d. Complete the request form and enter the "Seed Number" from the Diagnostic Tester. Click on Submit (Figure 7).

NOTE: All fields must be completed.







e. TIS will now return the Passcode that needs to be entered into the Diagnostic Tester.

NOTE: The Passcode given by TIS is only valid for one Immobilizer Reset Event.







C. Using the numbered keys (0-9) on the Diagnostic Tester, enter the "Passcode Number" received from TIS into the Diagnostic Tester (see Figure 9). Press ENTER to clear all registered transponder codes except the Master key in the ignition cylinder.

NOTE: ^ During the reset process do not remove the key from the ignition.

^ This step takes approximately 16 minutes.

^ Following a reset, the Transponder ECU is in auto registration mode.

^ Auto registration mode allows 3 Master Keys and one Sub Key to register automatically.

^ To register additional keys, remove the Master Key currently in the ignition. Insert keys (Master or Sub) into the ignition cylinder without turning the ignition on or off - simply insert and remove. (See Figure 9, screen D.)

NOTE: ^ If 4 keys are registered at this time, auto registration mode is automatically closed.

^ If less than 4 keys are registered at this time, auto registration mode must be closed manually by cycling the ignition ON/OFF more than 5 times in 10 seconds. (See Figure 9, screen E.)

^ If more than 4 keys need to be registered, use Transponder Code Registration.

D. Verify that keys are registered correctly by starting the engine with each newly registered key.

NOTE: ^ If the vehicle starts, the new key code was registered correctly.

^ If the vehicle does not start with any key, perform the Immobilizer Reset function again.

^ If only one of the registered keys will not start the vehicle, attempt to register the key again following the Transponder Code Registration procedure.

5. Transponder ECU Replacement

When the Transponder ECU is replaced, the transponder keys must be registered, auto registration closed, and ECU communication completed.

A. Replacement transponder ECUs are in auto registration mode. This allows transponder keys to automatically register as they are inserted into the ignition cylinder. It is possible to automatically register up to 3 Master Keys, and 1 Sub Key. Since the transponder ECU can distinguish the key type (Master or Sub), the registration order is not specified.

NOTE: ^ If 4 keys are registered at this time, auto registration mode is closed.

^ If less than 4 keys are registered at this time, auto registration mode must be closed manually by cycling the ignition ON/OFF more than 5 times in 10 seconds.

^ If more than 4 keys need to be registered, use Transponder Code Registration procedure.

B. Once auto registration mode is closed, ECU Communication must be performed between the transponder ECU and the Engine ECU. Complete ECU communication using the following steps:

a. Insert a registered Master Key into the ignition cylinder.

b. Turn the ignition ON (engine OFF).










c. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire (SST 09843-18020 or equivalent) and leave for 30 minutes. (See Figure 10.)

d. After 30 minutes, turn ignition OFF and remove check wire from DLC3.

e. Start the vehicle to confirm successful ECU communication.

NOTE: If ECU communication is not completed correctly, the engine will not start and DTC B2799 will be set. DTC B2799 will be cleared after the engine starts correctly.

6. Engine ECU Replacement








When the Engine ECU is replaced, ECU communication must be completed. ECU Communication must be performed between the transponder ECU and the Engine ECU. Complete ECU communication using the following steps:

A. Insert a registered Master Key into the ignition cylinder.

B. Turn the ignition ON (engine OFF).








C. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire (SST 09843-18020 or equivalent) and leave for 30 minutes. (See Figure 11.)

D. After 30 minutes, turn ignition OFF and remove check wire from DLC3

E. Start the vehicle to confirm successful ECU communication.

NOTE: If ECU communication is not completed correctly, the engine will not start and DTC B2799 will be set. DTC B2799 will be cleared after the engine starts correctly.
