NOTE: *: If a diagnosis code is sent for this function,
the display informs users whether a mechanical
problem currently exists or whether it existed before
but normal operation has been restored. The mes

IMMOBILIZER SYSTEM
M2540003000490
The engine immobilizer system prevents the engine
from starting and immobilizes the vehicle if a key
other than the key registered for that vehicle is used
in an attempt to start the engine after forced entry.
The engine immobilizer system consists of the igni
-
tion key, key ring antenna, immobilizer-ECU,
engine-ECU
works in the following way and has these functions.
1. With the ignition key turned ON, the transponder
(a small transmitter) integrated in the ignition key
transmits its own encrypted code to the ring
antenna via radio wave.
2. According to the sent encrypted code, the immo-
bilizer-ECU controls the engine-ECU
engine-CVT-ECU
encrypted code agrees with the pre-registered
one.
3. The system is designed to be maintenance-free because the power source for the transponder is
supplied by the immobi lizer-ECU. Three ignition
keys are provided, and up to eight keys can be
registered to one vehicle as needed. More than
one trillion of encrypted code combinations can
be registered, and parts of them are irregularly
changed whenever the ignition key is turned ON.
This feature prevents code copying, resulting in
higher security of the system.

Immobilizer-ECU with an
antenna•Supplies electrical power to the transponder integrated in the ignition key,
and transmits random number data.
•Verifies the encrypted code which is sent from the transponder. If the code
is correct, it sends an engine mobili zation signal to the engine-ECU
or engine-CVT-ECU
TransponderIs power-supplied by the immobilizer-ECU. When the transponder receives
random number data, it processes it an d the encrypted code. Then it transmits
the process result to the immobilizer-ECU.

confirmed, the ECU cancels the engine control and stops the engine.

Encrypted code registration criteria table
The ignition key contains a transponder (small trans-
mitter), which retains an unique encrypted code.
Under any of the conditions below, the encrypted
code must be registered in the immobilizer-ECU
again. The immobilizer-ECU can retain maximum
eight different encrypted codes. This means that
maximum eight ignition keys can be registered.

TECHNICAL FEATURES
GENERAL00-27
POWER WINDOW WITH SAFETY MECHA-
NISM
The power window with safety mechanism has been
adopted to automatically roll down and stop the door
window glass as soon as the occurrence of jamming
is detected at the time of rolling up the door window
glass.
SUNROOF WITH SA FETY MECHANISM
The sunroof with safe ty mechanism has been
adopted so that the roof lid glass can move in the
reverse direction and stop when application of exter
-
nal force hinders the movement during the sliding to
close or tilt down operation.
TRIMS AND HEADLINING
The head impact absorption structure has been
adopted for the pillar trim, quarter trim, and headlin
-
ing so that impact towards the head of a passenger
can be reduced.
