Immobilizer System Reprogram Procedure

NOTE
^ When an error occurs during the reprogram procedures except when both the immobilizer unit and PCM are replaced, repeat the procedure from step 1, If you still can not reprogram, confirm how many keys can start the engine.
Then, perform the key replacement or addition reprogram procedure according to the valid key number.
^ To make a copy of the key or replace the immobilizer system component parts (the key(s), steering lock, immobilizer unit and/or PCM), customer should bring all keys she/he has to the dealer. This is because the previously programmed key IDs are erased when reprogramming the key IDs into the immobilizer unit and PCM.
^ If customer has only one valid key when replacing the immobilizer system component parts, the dealer should contact a importer/distributor to obtain the code word.
^ To replace the immobilizer unit or PCM, there should be at least one valid key. Otherwise, both the immobilizer unit and PCM should be replaced.
^ The immobilizer unit and PCM cannot be changed from one car to another. If the immobilizer unit or PCM is replaced with one from another car, the engine will not start. Reprogramming of the IDs and code word of the Immobilizer unit that has already programmed as set is not possible.
^ The immobilizer unit and PCM should not be replaced with a new one as a trial during troubleshooting. If this is done, the ID and code word will be programmed into the new unit and it cannot be used for other cars even if you find that the old unit was normal.
^ The immobilizer system cannot be deactivated.
^ Confirm that all keys registered can start the engine after the reprogram procedure.
^ When customer does not need to register more than two keys, the following procedures can be stopped after registering two keys.
