IMMOBILIZER SYSTEM OUTLINE

E5U091467000N01

Note

• The construction and operation of the auxiliary key is described. Refer to “ADVANCED KEYLESS START

FUNCTION OPERATION” for starting engine with the card key. (See 09–14A–8 ADVANCED KEYLESS
START FUNCTION OPERATION.)

Special Features

• The immobilizer system is a vehicle theft prevention device that only allows keys that have previously been

programmed to the vehicle to start the engine. It functions to prevent theft by means such as a forged key or
hotwiring.

• The system consists of the key (with built-in transponder), coil antenna, PCM, instrument cluster, and keyless

control module.

• The immobilizer system activates automatically when the start knob is turned to the LOCK or ACC position.

(The security light in the instrument cluster flashes while the immobilizer system is activated.)

• When the start knob is pressed (push switch ON) and turned to the ON position with a previously programmed

auxiliary key, the immobilizer system deactivation operation begins automatically. The engine is allowed to start
only after the deactivation operation is completed successfully. (The security light illuminates for 3 s and then
goes out when the immobilizer system has been deactivated.)

• The immobilizer system cannot be disabled.

• Due to immobilizer system characteristics, the engine cannot be started unless two or more keys are

programmed. Therefore, when resetting the immobilizer system (PCM replacement, Keyless control module
replacement, or Replacement of all programmed keys), two or more keys usable with the immobilizer system
must be readied before starting the operation.

• A maximum of eight keys can be programmed to one vehicle. The PID/data monitor function can be used to

verify the number of keys programmed to the vehicle.

• If there is a system malfunction or the immobilizer system is not properly deactivated due to deactivation

operation failure, the malfunction location can be verified by the flashing pattern of the security light in the
instrument cluster, or using the malfunction diagnosis function of the on-board diagnostic system.

Caution

• If any of the following items are touching or near the key head, signal communication between the

key and vehicle is negatively affected, resulting in the engine not starting or a key programming
error. Do not perform procedures if any of the following items are touching or near the key head.

— Any metallic object

— Spare keys or keys for other vehicles equipped with an immobilizer system

— Any electronic device, or any credit or

other cards with magnetic strips
