C: Caution

Vehicle that does NOT have a keyless access with
push button start system, without security ID
(security tag) when the vehicle is new, and without
immobilizer CM

• 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.

A: Structure
An immobilizer system consists of the following
components: Combination meter or security CU
(for a model with security CU), immobilizer
indicator (in the combination meter), body
integrated unit, ECM, ignition key, and immobilizer
antenna.

• During immobilizer registration, do not bring
a key with a different ID close to the ignition
switch. When the 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.

B: Operation
When the ignition key incorporating a transponder
is inserted into the key cylinder, the body integrated
unit receives the ignition key ID via the immobilizer
antenna.
The received key ID is collated with the key ID
stored in the memory of the body integrated unit. At
the same time, the meter IDs (SCU IDs) stored in
the memory of the body integrated unit and
combination meter (or the security CU) are
collated.
Then, the engine IDs stored in the memory of the
ECM and body integrated unit are collated.
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 a mismatch of the IDs, the immobilizer
indicator in the combination meter turns on to
indicate that the immobilizer is active. When the
ignition key is removed, the immobilizer is activated
and the immobilizer indicator lamp flashes to
generate an alert notifying people around the
vehicle that it is protected by the immobilizer.

• When the engine cannot be started with a
registered key, pull the ignition key from the
ignition switch, wait approximately one
second until the immobilizer warning lamp
starts flashing, and then turn the ignition key
slowly to start the engine.
• Confirm that the battery voltage is 11 V or
more and execute each mode.
• During immobilizer registration, make sure
connectors do not get disconnected.
Note:
When performing either one of the operations
shown below, perform also the "Registering
Remote Control Engine Starter".
• Installing remote control engine starter
• Replacing remote control engine starter
• Replacing collation ECM of a vehicle
equipped with remote control engine starter
