IMMOBILIZER SYSTEM
CHASSIS ELECTRICAL54A-5
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 and engine-CVT-ECU . It
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 or
engine-CVT-ECU only when the sent
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.

Component name Outline of function
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.
Engine-ECU or
engine-CVT-ECU Starts the engine, and then continues the engine running if an engine
mobilization signal is co nfirmed. If an engine immobilization signal is
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.

COMBINATION METER
CHASSIS ELECTRICAL54A-10
COMBINATION METER
M2540005000894
The combination meter features large, clearly visible
analogue indicators. The meter has the speedometer
in the middle, the coolant temperature gauge at
upper right, the fuel gauge at lower right, and the
tachometer at left so that drivers can easily distin
-
guish the information from the meters. The combina-
tion meter offers the following advantages.
•The combination meter is used for air conditioner
and meter drive control to integrate ECU.
•CAN communication is used for more reliable
transmission of all gauge data and indicator lamp
input signals, such as vehicle speed, engine
RPM, and coolant temperature. For further
details on CAN, refer to GROUP 54C, CAN
P.54C-2. The signals that the combination meter
uses are described in the CAN communications
input signals table
.
•Several diagnosis functions such as the diagno-
sis code memory and actuator tests are prepared
in order to improve serviceability.
•For a brighter display at night and for a longer
useful life, all indicator lamps, warning lamps, and
illumination bulbs use LEDs.
•The indicators for the speedometer, fuel gauge,
and other gauges are driven by a stepping motor.
For further details, consult the stepping motor
section
.
•The electronic speedometer operates by receiv-
ing vehicle speed signals sent by the
engine-ECU or engine-CVT-ECU
via the CAN.
•A large and clear LCD type odo-tripmeter is pro-
vided. The odometer continuously displays val-
ues while the tripmeter adopts a twin-trip (trip A,
trip B) function which is switched by a reset but
-
ton. In addition, clock function is incorporated.
•A fog lamp indicator lamp is provided to let the
driver know that the fog lamp is on.
•A seat belt warning lamp is installed to encourage
the driver to fasten the seat belt.
•The high-contrast meter is adopted. When the
ignition is turned ON, such as the needles and
face display are illuminated with fade-in lighting
by the LED light source.
•To further accentuate the high-contrast lighting,
the light of the high-contrast meter fades in and
fades out when the light is turned on and off
respectively.
•With the auto illumination function incorporated in
the high-contrast meter, a two-stage switching of
daytime (non-dimming) and nighttime (dimming)
is achieved. Also, the brightness can be adjusted
using the illumination control knob.
•A tail lamp indicator lamp is installed which
informs the lighting status of the tail lamps to the
driver.
