NOTE:
If an incorrect password is input five times in a row, immobilizer-ECU assumes an unauthorized operation is being attempted. Start prevention mode will be set, and engine will not function. To clear start-prevention mode, turn ignition switch to ON position and wait 20 minutes.
NOTE:
If ignition key, immobilizer-ECU or PCM is replaced, encrypted codes of all ignition keys must be registered.
