7) Immobilizer Control
(1) Overview
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is turned
to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if correct,
allows the vehicle to start the engine.
For details, refer to Chapter "BCM".

5. CAN COMMUNICATION CONFIGURATION
The CAN topology is linked with CAN communication system, which consists of P-CAN and B-CAN.
The instrument cluster and BCM (Body Control Module) communicate through both P-CAN and B-CAN
at the same time, and the SKM (SMART Key Module) communicates with the instrument cluster and
BCM through B-CAN.

Speed sensitive intermittent wiper ▶
The BCM without rain sensor operates the wiper as follows:
When turning the ignition switch to ON from OFF position with the intermittent wiper switch in "ON"
position, the wipers do not operate.
When turning the wiper switch to ON from OFF position after turning the ignition switch to ON position,
the wipers operate one cycle.
The wiper's operation cycle depends on the vehicle speed (CAN communication with instrument
cluster) and wiping speed the side fascia panel.

4) Door Ajar Warning
While the BCM without SKM controls the warning lamp, the BCM with SKM controls the warning lamp
and sends the signal via the BCAN communication. But, this control is available only when any of doors
or tailgate, except engine hood, is open.
The instrument cluster controls the door ajar warning lamp according to the signal from the BCM.
(However, the BCM controls the door ajar warning lamp with the electric wire together with the BCAN
communication.)
Also, the instrument cluster controls the blinking function according to the vehicle speed.
(However, the BCM controls the door ajar warning lamp blinking with the electric wire together with
the BCAN communication.) 1.

(*1) : Ajar: Driver, passenger, rear door or tailgate is open
Close: Driver, passenger, rear door and tailgate are closed

5) Seat Belt
Seat belt warning ▶
When turning the ignition switch (IGN1) to ON from OFF position, the BCM sends the driver and front
passenger seat belt warning signals to the instrument cluster module through the CAN
communication, and the buzzer sounds for 0.6 seconds with the interval of 0.02 s ON and 1.38 s
OFF. If the driver/passenger seat belts are fastened, the buzzer does not sound but the warning lamp
blinks during the period. (the buzzer is controlled by BCM and the warning lamp is controlled by ICM)
For the passenger seat, however, the system detects if the passenger seat is empty or occupied and
operates the warning lamp only for the first time.
After that, the only seat belt reminder detects if the passenger seat is occupied.
For the driver seat, the seat belt reminder operates only when the seat belt is not fastened at the
vehicle speed of 25 km/h or higher.
The instrument cluster module controls the driver/passenger seat belt warning lamps by receiving the
driver/passenger seat belt warning lamp signals.
When turning the ignition switch (IGN1) to OFF position during the warning operation, the buzzer
stops and the warning lamp goes off.
If the driver/passenger seat belt is fastened during the warning operation, the buzzer stops but the
warning lamp blinks for the remaining time of the period.
If the driver/passenger seat belt signal changes to "unfastened" from "fastened" with IGN1 ON, the
driver/passenger seat belt warning lamp comes on and the buzzer sounds again for 0.6 seconds.
But, if the condition for seat belt reminder operation is met during the warning operation, the warning
operation stops and the seat belt reminder function is activated. 1.

Seat belt reminder ▶
Operating conditions for seat belt reminder are as follows: IGN ON, engine running (over 300 rpm),
vehicle speed of 25 km/h or higher, driver seat belt unfastened, passenger seat belt unfastened and
passenger seat occupied. In addition, if the seat belt reminder is activated at the speed of 25 km/h or
higher and the speed reduces to below 25 km/h within 5 minutes, the interior buzzer sound stops. The
buzzer sounds for 5 minutes again when the speed is 25 km/h or higher.
The seat belt reminder stops its operation when fastening the seat belt, but starts the operation again if
unfastening the seat belt.
If the seat belt reminder is initially operated due to unfastened driver seat belt, the buzzer sounds with
the interval of 0.02s ON/1.18s OFF, the instrument cluster sends the driver seat belt warning signal
(SBR) and the seat belt warning lamp stays on.
At this time, the buzzer sounds for 5 minutes.
If the seat belt reminder is operated due to unfastened passenger seat belt when the passenger seat
belt reminder sensor detects that the passenger seat is occupied, the instrument cluster sends the
driver seat belt warning signal and the seat belt warning lamp stays on.
For this case, the indicator shows each status of the driver and passenger seats but the indoor buzzer
is common to both seats.
If the simultaneous operating condition for the indoor buzzer is met, the driver seat has the priority.
If the driver seat belt is fastened, the same operation is also carried out in the passenger seat
automatically.
The buzzer and the warning lamp are operated according to the vehicle speed as below table during
the seat belt reminder operation. 1.
