Engine Immobiliser System (W/O Smart Key System)








ENGINE IMMOBILISER: ENGINE IMMOBILISER SYSTEM (w/o Smart Key System): REGISTRATION

REGISTRATION

1. DESCRIPTION OF CODE REGISTRATION
HINT:
- The key code (immobiliser code) is needed when the transponder key ECU, hybrid vehicle control ECU or key is replaced with a new one.
- The key has 2 codes: the key code and the wireless code. Both of these code types need to be registered when the key is replaced with a new one. Refer to the following key code registration procedures and the entry and wireless code registration procedures Registration.

2. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES
(a) The following table shows ECU replacement and key registration procedures in case the malfunctioning ECU has been determined after troubleshooting the engine immobiliser system.
HINT:
- The following procedures indicated in the table below require the use of the Techstream:
- New key code registration
- Additional key code registration
- Key code erasure
- ECU code registration
- If all of the registered keys are not available, replacement of the transponder key ECU is also required.





3. KEY REGISTRATION IN AUTOMATIC REGISTRATION (NEW REGISTRATION)
(a) When a key is inserted into the key slot, the key code (immobiliser code) registration is automatic. In this mode, a maximum of 2 key codes can be registered.
HINT:
- When a new transponder key ECU is installed, key codes (immobiliser codes) must be registered in the transponder key ECU.
- New transponder key ECU are automatically set to automatic key code registration mode.





(b) End automatic key code registration mode.
Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for the key has been registered.
(1) Turn the power switch from ON (IG) and OFF 5 times within 10 seconds using the already registered key.
HINT:
- When no key is inserted into the key slot in automatic key code registration mode, the security indicator light remains on.
- When the immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
- If the key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator light. Trying to reregister 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 light. The output details are shown below.





4. REGISTRATION OF ADDITIONAL KEY (ADDITIONAL REGISTRATION)
(a) Register an additional key using the Techstream.
HINT:
- A maximum of 5 key codes can be registered.
- Registration mode will be ended if each step is not completed within the specified time.




HINT:
- A brief outline of procedures for key code registration is shown above. For more detailed information, refer to the Techstream screen's instructions.
- When the immobiliser system is operating normally and key is pulled out, the security indicator light blinks continuously.
- If the key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator light. Trying to reregister an already registered key will be 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 light. The output details are shown in the "KEY REGISTRATION IN AUTOMATIC REGISTRATION (NEW REGISTRATION)" procedures.

5. ERASURE OF KEY CODE
(a) Erase the key codes using the Techstream.
HINT:
- All key codes are erased except for the key that is used to erase the key codes. In order to use a key whose code has been erased, a new key code must be registered.
- Registration will be canceled if each step is not completed within the specified time.




HINT:
- A brief outline of procedures for the key code erasure is shown above. For more detailed information, refer to the Techstream screen's instructions.
- When the immobiliser system is operating normally and key is pulled out, the security indicator light blinks continuously.

6. ECU COMMUNICATION ID REGISTRATION (TRANSPONDER KEY ECU - HYBRID VEHICLE CONTROL ECU)
NOTICE:
- If the transponder key ECU and/or hybrid vehicle control ECU has been replaced, register the ECU communication ID to both ECUs in order to match their IDs.
- The hybrid control system cannot be started unless the ECU communication ID matches.
- When the transponder key ECU has been replaced, do not turn the power switch from ON to OFF 20 times or more consecutively. The ECU communication ID must be registered before such an occurrence or the transponder key ECU will need to be replaced. If the transponder key ECU is unable to be recognize the hybrid vehicle control ECU, the hybrid control system will be unable to be started. If the transponder key ECU cannot recognize the hybrid vehicle control ECU, the transponder key ECU must be replaced again with a new one.
- After the registration, pressing the power switch may not start the system on the first try. If so, press the poser switch again.
- After the hybrid control system is started, erase DTC B2799 (code for hybrid vehicle control ECU's immobiliser communication error) using either of the following:
- Using the Techstream Engine Immobiliser System (w/o Smart Key System).
- Disconnect the battery for 30 seconds.

(a) Register the ECU communication ID.
(b) Using SST, connect terminals TC and CG of the DLC3.
SST: 09843-18040





(c) Turn the power switch ON (IG) (do not start the hybrid control system) and leave it as is for 30 minutes.
(d) Turn the power switch OFF and disconnect terminals TC and CG.
(e) Check that the hybrid control system starts.
7. ECU COMMUNICATION ID REREGISTRATION (TRANSPONDER KEY ECU - HYBRID VEHICLE CONTROL ECU)
NOTICE:
- The ECU communication ID should be registered when the hybrid vehicle control ECU is replaced in order to match the ECU communication ID (transponder key ECU - hybrid vehicle control ECU).
- The hybrid control system cannot be started unless the ECU communication ID (transponder key ECU - hybrid vehicle control ECU) matches.

(a) Insert the already registered key in the key slot and turn the power switch ON (READY) with the brake pedal depressed.
(b) Check that the hybrid control system stays on for more than 3 seconds.
