(14) Immobilizer control
A. Overview
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is
turned to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if
correct, allows the vehicle to start the engine.

13) Theft Deterrent
(1) Description of Burglar Alarm Function
The “LOCK” output is “ON” when receiving the “LOCK” signal from transmitter while the
ignition key is removed and all doors are closed. The armed mode is activated when the door lock
switch is locked (theft deterrent horn output: once, hazard relay output: twice).
The theft deterrent horn and hazard relay outputs are “ON” when receiving the “LOCK” signal
from the remote control key again in armed mode (theft deterrent horn output: once, hazard relay
output: twice).
When receiving “LOCK” signal from the remote control key while any of doors is not closed,
only the “LOCK” output can be done and then activates the armed ready mode (without theft
deterrent horn and hazard warning flasher). At this moment, if the ignition key is in the ignition switch,
the door unlock switch is turned “ON” or the door lock switch is unlocked (after 0.6 seconds),
cancels the armed mode and activates the normal mode. However, in these cases, if closing the
door and locking the door lock switch, the theft deterrent horn outputs once and the hazard warning
flasher outputs twice and then activates armed mode.
When the door is not opened or the ignition key is not inserted into ignition switch for 30 seconds
after receiving “UNLOCK” signal, outputs “LOCK” and then activates armed mode (RELOCK
operation). Also, at this moment, the system outputs the theft deterrent horn and hazard warning
flasher.
The armed mode will not be activated except above conditions.
Ex) The armed mode will not be activated when the door is locked by the ignition key. 1.
