SECURITY AND LOCKS [ADVANCED KEYLESS SYSTEM]
IMMOBILIZER SYSTEM CONSTRUCTION/OPERATION
• Keys contain a unique ID number that is previously programmed to the keyless control module and PCM. Due
to this, if immobilizer system component parts are replaced (such as key addition/clearing or replacement of
the keyless control module, instrument cluster or PCM), it is necessary to reset the system.
Key ID Number Verification Procedure
The start knob is pressed and the ignition switch is turned
to the ON position.
