THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM: REGISTRATION; 2013 MY FR-S [03/2012 -]

1. DESCRIPTION OF CODE REGISTRATION

(a) The key has 2 codes: the key code (immobiliser code) and the wireless code. Both of these codes need to be registered. For the wireless code registration procedures, refer to Wireless Door Lock Control System Registration.

Key code registration is necessary when the main body ECU (network gateway ECU), combination meter assembly*1 or transponder key ECU assembly*2 or key is replaced with a new one.

* *1: w/o Transponder Key ECU Assembly

* *2: w/ Transponder Key ECU Assembly

2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

HINT
* The following procedures require the use of the Techstream:
* New key code registration
* Key code re-registration
* Additional key code registration
* Key code erasure
* A maximum of 6 key codes can be registered.






3. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES

(a) The following table shows ECU replacement and key registration procedures for cases in which an ECU has been determined to be malfunctioning during troubleshooting of the engine immobiliser system.

HINT
* The following procedures require the use of the Techstream:
* New key code registration
* Key code re-registration
* Additional key code registration
* Key code erasure
* A maximum of 6 key codes can be registered.









* *1: w/o Transponder Key ECU Assembly

* *2: w/ Transponder Key ECU Assembly

* *3: If none of the registered keys are available, the main body ECU (network gateway ECU) cannot authenticate users, and it will be necessary to replace the combination meter assembly*1 or transponder key ECU assembly*2 with new ones. However, if there is at least one registered key available, erasing the key code before replacing the main body ECU (network gateway ECU) will make it unnecessary to replace the combination meter assembly*1 or transponder key ECU assembly*2. After replacing with a new combination meter assembly*1 or transponder key ECU assembly*2, register all keys as new key codes, and carry out ECU communication ID registration.
