IMMOBILIZER SYSTEM CONSTRUCTION/OPERATION

E5U091467000N03

• 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.

The PCM verifies that the received key ID number matches
the key ID number which has already been programmed.

Engine start is enabled.
(The security light illuminates approx. 3 s and goes off.)

Engine start is disabled.
(The security light starts flashing/illuminating after an
error, such as verification failure or malfunction, is
detected, and then indicates the DTC for ten times
repeatedly.)

Immobilizer System Setting

• Some immobilizer system settings can be performed only using the WDS or equivalent. When using the WDS

or equivalent, first, security access must be requested. Obtain security access permission according to the
WDS or equivalent screen and then perform system procedures.

• When immobilizer system component parts (key, PCM, coil antenna, and keyless control module) are replaced,

the system must be reset as described below. Refer to the Workshop Manual for the detailed setting procedure.

AUXILIARY KEY CONSTRUCTION

E5U091467000N04

• Keys for use with the immobilizer system have an

electronic communication device (transponder)
built into the key head that retains specific
electronic codes (key ID number).

WDS or equivalent setting items

Contents

Programming an additional ignition key

Allows key ID number programming.

Ignition key ID number clearing

Clears all programmed key ID numbers and programs new key ID
numbers.

Customer spare key programming enable

“Additional ignition key programming” is enabled.

Note

• This is the default setting on new vehicles.

Customer spare key programming disable

“Additional ignition key programming” is disabled.

Note

• When only the WDS or equivalent must be used to program

key ID numbers, making a forged key by using two keys that
can start the engine is prevented. This function is for use by
rental car agencies or other companies with vehicle fleets.

Component part

Setting

Key addition

Key ID number of added key must be programmed. Key ID number programming can
be performed according to the following methods:

• Method for programming additional keys using two keys that can start the engine

• Method using the WDS or equivalent

Key clearing

The programmed key ID number can only be cleared using the WDS or equivalent.
When clearing key ID numbers using the WDS or equivalent, all the programmed key
ID numbers are cleared.

PCM replacement

• The key ID numbers for all keys that were being used must be programmed using

the WDS or equivalent. Two or more keys must be programmed.

Instrument cluster

• The key ID numbers for all keys that were being used must be programmed using

the WDS or equivalent. Two or more keys must be programmed.

Keyless control module replacement

• Card key and steering lock unit must be programmed.

• The key ID numbers for all keys that were being used must be programmed using

the WDS or equivalent. Two or more keys must be programmed.

Steering lock unit replacement
(including key replacement)

• Steering lock unit must be programmed.

• The key ID number must be programmed using the WDS or equivalent. Two or

more keys must be programmed.

Coil antenna replacement

Immobilizer system resetting is not necessary.

• Installed on the steering lock.

• Forms a magnetic field near the steering lock and

communicate to the key.

• Demodulates the received key signal and outputs

the signal to the keyless control module.

SECURITY LIGHT CONSTRUCTION/OPERATION

E5U091467000N06

Construction

• Allows visual confirmation of immobilizer system operation.

• If any malfunction is detected in the immobilizer system, the malfunction location can be verified by the security

light illumination/flashing pattern.

Caution

• Always use the WDS or equivalent to verify DTCs even if the security light indicates a DTC. If the

security light itself has a malfunction, a DTC may not be indicated properly.

Operation

• When the immobilizer system is operating, the

security light flashes repeatedly 0.1 s every
approx. 2 s.

• When the immobilizer system is deactivated

normally, the security light illuminates for approx.
3 s and then goes out when the start knob is
turned to the ON position.

• If the immobilizer system is not deactivated

normally (malfunction detected by the malfunction
diagnosis function), the security light indicates a
DTC. When the start knob is turned to the ON
position, the security light flashes or illuminates
for 1 min in the following pattern:

— DTC 15 or lower: Flashes

— DTC 21: On

Note

• The security light indicates the DTC 10

times.

• If multiple DTCs that can be confirmed with

the security light are detected, only the DTC
with the lowest number of those detected will
be indicated by the security light.
