IMMOBILIZER SYSTEM CONSTRUCTION/OPERATION
• When a key is inserted into the key cylinder, the key ID number of the key and the key ID number registered in
the PCM are compared. If the comparison is successful, permission is given to start the engine. For PCM
control, see Section 01, CONTROL SYSTEM.
• Keys contain a unique ID number that is previously registered in the instrument cluster. Due to this, if
immobilizer system component parts are replaced (such as key addition/clearing and instrument cluster
replacement), it is necessary to reset the system.
