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 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.

The security indicator light reveals the following information:
Always ON and NO key in IG
* = Transponder ECU in Auto Registration mode
Blinking and NO key in IG = Normal operation

C. Using the numbered keys (0±9) on the Diagnostic Tester, enter the ªPasscode
Numberº received from TIS into the Diagnostic Tester (see Figure 9 below).
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. Operation

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 (page 5 of
this bulletin).
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 3 Master Keys, and 1 Sub Key.
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 (page 5 of this bulletin).
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 registered Master Key into the ignition cylinder.
b. Turn ignition ON (engine OFF).
c. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire
(SST 09843±18040 or equivalent) and leave for 30 minutes. (See Figure 10.)

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 engine starts correctly. Operation
