POWER DOOR LOCK SYSTEM OPERATION

E5U091466000N05

• When the driver’s door is locked/unlocked with the driver’s door lock knob or key cylinder, the door lock-link 

switch in the door lock actuator is locked/unlocked via the rod.

• The keyless control module activates each lock actuator to lock/unlock according to the lock/unlock signal from 

the door lock-link switch.

• The doors also can be locked/unlocked by operating the key or transmitter.

• The answer-back function has been adopted where the hazard warning lights flash and a buzzer sounds to 

confirm that the doors are locked/unlocked.

• A rolling code type transmitter has been adopted to prevent theft by radiowave interception.

• To prevent improper operation while the vehicle is moving, the doors cannot be locked/unlocked by operating 

the transmitter if the ignition key is not in the LOCK position.

KEYLESS ENTRY SYSTEM OPERATION

Lock/unlock

Note

• If any of the following conditions are met, the doors cannot be locked by operating the transmitter.

— The key is inserted in the ignition key cylinder.

— The ignition switch is not in the LOCK position.

— Any door is open.

• If any of the following conditions are met, the doors cannot be unlocked by operating the transmitter.

— The key is inserted in the ignition key cylinder.

— The ignition switch is not in the LOCK position.

1. When the transmitter is operated, the transmitter sends ID data and rolling code. They are received by the 

keyless receiver and sent to the keyless control module.

2. When the keyless control module receives a lock/unlock signal from the transmitter and verifies the ID, the 

signal is sent to the all lock actuators activate to lock/unlock.

3. The keyless control module operates the hazard warning light to flash according to lock/unlock signal from the 

transmitter.

— When the LOCK button is pressed, the hazard warning lights flash once.

— When the UNLOCK button is operated, the hazard warning lights flash twice.

IMMOBILIZER SYSTEM OUTLINE

E5U091467000N09

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

registered to the vehicle to start the engine. Therefore, it functions to prevent theft by means such as a forged 
key or electrical 'hotwiring'.

• Consists of the key (with built-in transponder), coil antenna, PCM, instrument cluster and security light (in the 

instrument cluster).

• The immobilizer system operates automatically when the ignition switch is turned to the LOCK or ACC position. 

(The security light illuminates when the immobilizer system is in operation)

• When the ignition switch is turned from the LOCK (or ACC position) to the ON (or START position) with a 

previously registered key, the release operation begins automatically. The engine is allowed to start only after 
this operation is successful. (The security light illuminates for 3 s and then goes out when the immobilizer 
system has been released.)

• The immobilizer system cannot be deactivated.

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

registered. Moreover, when performing “Instrument cluster replacement”, “PCM replacement”, or “Replacement 
of all the keys”, two or more keys usable with the immobilizer system must be readied.

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

the number of keys registered for a single vehicle.

• If there is a system malfunction or the immobilizer system is not properly released due to release operation 

failure, the malfunction location can be verified 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 
registration 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

IMMOBILIZER SYSTEM CONSTRUCTION/OPERATION

E5U091467000N12

• 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.
