IMMOBILIZER SYSTEM REPROGRAM PROCEDURE

BME091467000W01

  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 cannot reprogram, confirm how many keys can start the engine. Then, perform the key replacement or additional 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), the customer should bring all keys 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 the customer has only one valid key when replacing the immobilizer system component parts, the dealer should contact a 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 an immobilizer unit that has already been programmed is not possible.
  • The immobilizer unit and PCM should not be newly replaced 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 confirming, wait for more than 5 seconds before inserting the next key.
  • When the customer does not need to register more than two keys, the following procedures can be stopped after registering two keys.
  • If the key cannot be registered in spite of the fact that the immobilizer system operates normally, there may be a malfunction with the key reminder switch or wiring harness.
