C: Caution

Vehicle that has a keyless access with push button
start system and is originally NOT provided with a
security ID (security tag)

• When you install wireless radios or car
phones, make sure that the immobilizer
system is not influenced by their electric
waves.
• Do not operate cell phones or wireless radios
or the like when either trouble diagnosis or
immobilizer registration is in progress.
• During immobilizer registration, do not bring a
key with a different ID close to the ignition
switch. When the access key is on a keychain,
remove it from the chain before start of
diagnosis. When there are several keys on one
keychain, remove them from the keychain and
use them individually for the work.
• The work of "Registering the Smart
Immobilizer", "Registering the Smart ECM"
and "Delete the Mobile Key (Access Key) ID"
includes the operation of holding up the
access key to the push engine switch (pushbutton ignition switch). Pay attention to the
following when performing this operation.
• Confirm that the battery voltage is 11 V or
more and execute each mode.
• When confirm/register access key, only
one key can be brought into vehicle at a
time. For registration of multiple keys,
bring a key into vehicle and perform
registration while leaving rest of other
keys outside.
• When holding up the access key to the
push engine switch (push-button ignition
switch), do not hold two or more access
keys at the same time, but use only one
each time. (When the access key is on a
keychain, remove it from the keychain
before the work.)
• When holding the access key up to the
push engine switch (push-button ignition
switch), bring the access key close to the
push engine switch (push-button ignition
switch) as shown below.

A: Structure
An immobilizer system consists of the following
components: Immobilizer indicator (in the
combination meter), ECM, access key, immobilizer
antenna (incorporating a push switch), keyless
access CM, steering lock CM, ID code box (for a
model with ID code box), indoor and outdoor
antennas, and receiver (may be incorporated in
keyless access CM).

B: Operation
Get in the vehicle with your access key and let the
access key send the ID via the indoor antenna. The
access key sends the ID to the receiver and the
received ID is sent to the collation CM where it is
collated with the IDs of other immobilizer-related
units. Step on the brake pedal (for an AT model) or
clutch pedal (for a MT model) and press the push
engine switch so that the starter rotates to start the
engine.
If the IDs do not match within the specified period of
time after the RPM of the engine reaches the
specified RPM, the engine stops. If the IDs do not
match, the engine stops within a couple of
seconds. If the engine does not start as a result of
