Engine Immobilizer System: Registration

HINT:

The key has 2 codes: The key code (immobilizer code) and the wireless code. Both of these codes need to be registered. Refer to the wireless code registration procedures.

1. When adding master keys or sub key (Additional registration):
   1. Register the key code (immobilizer code) in the transponder key ECU.

      Target ECU	See procedure
      Transponder key ECU	Procedure "A"

2. When replacing the transponder key ECU (New registration):
   1. Register the key code (immobilizer code) in the transponder key ECU.

      Target ECU	See procedure
      Transponder key ECU	Procedure "B"

   2. Register the ECU COMMUNICATION ID between the hybrid vehicle control ECU and the transponder key ECU.

      Target ECU	See procedure
      Transponder key ECU	Procedure "C"

3. When replacing the hybrid vehicle control ECU:
   1. Register the ECU COMMUNICATION ID between the hybrid vehicle control ECU and the transponder key ECU.

      Target ECU	See procedure
      Transponder key ECU	Procedure "C"

1. When an ignition key is inserted into the ignition cylinder, the key code (immobilizer code) registration is automatic. In this mode, a maximum of 4 key codes for 3 master keys and 1 sub key can be registered. Any order of registration for master keys and sub key is acceptable fine because the transponder key ECU can distinguish between different types of keys.

   HINT:

   • When a new transponder key ECU is installed, key codes (immobilizer codes) must be registered with ignition keys.
   • New transponder key ECU will be automatically set to automatic key code registration mode.

     Procedure	Security Indicator Condition
     1. Start (Procedure "D")	Blinking occurs until the first key is inserted.
     2. Insert the key into the ignition key cylinder.	ON
     3. Registration begins. HINT: The registration will be completed approx. 1 sec. after the key is inserted.	OFF HINT: Apporx. 1 sec.
     4. Remove the key.	ON HINT: When the maximum number of the key codes is registered, the security indicator remains off until the last key registered is removed. After it is removed, the security indicator starts blinking.
     5. Register another key ? Yes: Go to procedure "D" . No: Go to procedure "E"
     6. End (Procedure "E")

   HINT:

   • When no key is inserted in the key cylinder while the system is in automatic key code registration mode, the security indicator remains on.
   • When the immobilizer system is operating normally and the key is pulled out, the security indicator blinks continuously.
   • If the key code registration has failed in the automatic key code registration mode, code 2-1 will be output from the security indicator. Trying to register an already registered key will cause code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will be output from the security indicator. The output details are shown below.

2. Finish the automatic key code registration mode. The automatic key code registration mode can be forced to end when at least 1 key code (immobilizer code) for the master key has been registered.
   1. Turn the ignition switch on and off 5 times within 10 seconds using the already registered master key.

1. Register an additional key by using the intelligent tester.

   HINT:

   • A maximum of 5 master 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. 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 (taken from the original master key). However, the new master key will not be able to lock and unlock doors through the door key cylinder. It is advisable to keep the original master key. If the new master key's transmitter module's battery fails, the original master key can be used to lock and unlock doors through the door key cylinder.

   Procedure	Time (Completion of operation)	Security Indicator Condition
   1. Start	-	The indicator will blink until the first key is inserted.
   2. Insert the already registered master key in the ignition key cylinder and turn the ignition switch on.
   3. Intelligent tester operation: Select IMMOBILIZED Select ID UTILITY. Select TRANS CODE REG HINT: After completing the above operation, proceed to the next step in accordance with the prompts on the tester screen.	Within 120 sec.	OFF
   4. Remove the master key.	Within 20 sec. of the instruction on the tester.	ON
   5. Insert the key to be registered in the ignition key cylinder.	Within 10 sec.
   6. After 60 sec. the key is registered. HINT: Security indicator goes off.	-	Blinking
   7. Next		OFF
   8. End

   NOTE: If the key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator. Trying to register an already registered key will cause code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will be output from the security indicator. The output details are shown in procedure "B".

   HINT:

   • A brief outline of procedures for key code registration is shown above. For detailed information, please refer to the screen of the intelligent tester.
   • When the immobilizer system is operating normally and the key is pulled out, the security indicator will blink.

1. Erase key codes by using the intelligent tester.

   HINT:

   • All key codes will be erased except for the master key which is used for erasing the key codes.

     In order to use a key for which the code has been erased, it is necessary to register the key code again.

   • The registration operation will be cancelled if each step is not completed within the specified time.
