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.

fuse box
The fuse and relay boxes in this vehicle are mounted on the engine compartment, left side of the
instrument panel and rear of the instrument cluster (3 off in total). The capacities and its names for each
fuse and relay are marked on the each fuse and relay box cover.
The label attached on each fuse box indicates only major fuses and relays. For detailed information, see
the power distribution circuit diagram.

Seat belt internal buzzer (chime) and warning lamp
The ignition is turned ON from OFF with the driver and passenger seat belts unbuckled.
The internal buzzer (chime) sounds and the warning lamp comes on for 6 seconds (T2).
(internal buzzer controlled by BCM, warning lamp controlled by instrument cluster) A.
B. Operation 1.
The ignition is turned ON from OFF with the driver and passenger seat belts unbuckled.
The internal buzzer (chime) does not sound but the warning lamp comes on for 6 seconds (T2).
(The seat belt reminder is operated when the vehicle is driven at 10 km/h (for EU), 25 km/h (for GEN)) C.
D. Operation 2.
When the fastened driver seat belt is unbuckled with IGN ON.
The internal buzzer (chime) sounds and the driver seat belt warning lamp comes on for T2 again. E.
F. Operation 3.
The ignition is turned OFF while the internal buzzer (chime) and seat belt warning lamp are activated.
The internal buzzer (chime) and seat belt warning lamp are deactivated. G.
H. Operation 4.
8. SEAT BELT CONTROL
The driver seat belt is fastened while the internal buzzer (chime) and seat belt warning lamp are
activated.
The internal buzzer (chime) does not sound but the warning lamp comes on for the time remaining. I.
J. Operation 5.
When the seat belt reminder operation conditions are met during the warning, the seat belt reminder
is operated after stopping the warning output.
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. -

Seat belt reminder operation
A
BIf the seat belt is fastened after the seat belt reminder is activated, the output of the reminder is
turned OFF immediately. The reminder will be operated again whenever the seat belt is
unbuckled.
CWhen the seat belt reminder is activated initially with the seat belt unbuckled, the internal buzzer
(chime) is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle
continues for 5 minutes) and the driver seat belt warning lamp on the instrument cluster remains
on.
DWhen the seat belt reminder is activated with the seat belt unbuckled, the internal buzzer (chime)
is turned ON for 0.02 seconds and then turned OFF for 1.18 seconds (this cycle continues for 5
minutes) and the passenger seat belt warning lamp on the instrument cluster remains on, after
detecting that the passenger seat is occupied through the input value of the passenger seat
occupancy sensor.
EWhen the vehicle speed is changed while the seat belt reminder is turned on, the internal buzzer
(chime) is operated as follows:
FPriority of internal buzzer (chime) operation
(Seat belt reminder > ignition key reminder > sunroof warning > tail lamp warning > hazard
warning flasher on > turn signal indicator)GEN
The seat belt reminder is operated when the
vehicle is driven at 25 km/h or more with IGN
ON and alternator in High status (engine
running), and driver seat belt is not fastened. If
the vehicle speed is decreased to less than 25
km/h within 5 minutes after the seat belt
reminder is activated, the internal buzzer
(chime) is turned off. If the vehicle speed is
increased to 25 km/h or more, the buzzer
signal is output for 5 minutes. Only EU If the driver and passenger seat belts are not
fastened with the ignition switch ON, engine
running, vehicle speed above 10 km/h and
any passenger occupied, the seat belt
reminder is activated. In addition, even though
the vehicle speed reduces to below 10 km/h
after the reminder is activated at speed of 10
km/h or higher, it will remain activated.
