Kia Carens: Anti-theft System / Description and operation
Anti theft device
| • |
BCM : Arming-Disarming data output
|
| • |
SIREN : Siren ON when disconnecting the battery, TILT & UIP sensor input
|
| • |
OFF switch : Alarm function OFF
|
| • |
TILT sensor : Sense the vehicle angle
|
| • |
UIP (Ultrasonic Intrusion Protection) sensor : Sense the unauthorised
entry
|
This system is designed to provide protection from unauthorised entry into the
vehicle.
This system is operated in three stages :
the first is the "Armed" stage, the second is the "Theft-alarm" stage, and the
third is the "Disarmed" stage.
If triggered, the system provides an audible alarm with blinking of the hazard
warning lights.
Function
| 1. |
Siren
| (1) |
Power On-Off
It is necessary to apply voltage to the SIREN to power-on the
SIREN.The SIREN saves its status into the internal memory. Before
removing the car battery supply or SIREN/Sensors connector.
Take care that the system is in DISARM state otherwise it will
start to sound using the internal battery.
|
| (2) |
Arming-Disarming
The system is armed by BCM specific command on LIN BUS
Conditions to ARM the SIREN
| –
|
IGN OFF
The system is disarmed by BCM specific command on LIN
BUS
|
Conditions to ARM the SIREN
|
| (3) |
Arming Disarming signaling
The BCM manages the blinker activation during DISARM to ARM,
ARM to DISARM and ALARM to DISARM transition.
|
| (4) |
Functional States
| –
|
DISARM STATE
In this state the vehicle is not protected
|
| –
|
Pre ARM/ INHIBITION Time
The Pre ARM or INHIBITION TIME starts when the SIREN
receives an ARM command by IPM.
If one or more protections are active during DISARM/ARM
transition or during the inhibition time, the SIREN
exclude it automatically(except for UIP and TILT sensor).
It will be re-included in the protection when it will
return in the correct condition A continuous low power
sound indicated the exclusion during Pre Arm/INHIBITION
time.
The INHIBITION Time duration is 30 sec starting from
DISARM to ARM transition.
|
| –
|
ARM STATE
In this state the vehicle is fully protected
|
| –
|
Partical ARM STATE
In this state the vehicle is not fully protected : the
UIP and TILT sensor are excluded.
|
| –
|
ALARM STATE
In this state the SIREN is sounding using vehicle battery
if present, otherwise its internal.
|
| –
|
ALARM PAUSE STATE
The ALARM PAUSE STATE is a state among two consecutive
ALARM STATE
|
|
| (5) |
Stabilization Time
The Stabilization Time is the time that the external sensor(UIP
and TILT) need to stabilize the function when system are armed.
The Stabilization time duration for UIP and TILT sensor is 30
sec starting from DISARM to ARM transition.
|
| (6) |
Alarm Causes
The SIREN activates the sound and send to the BCM a LIN BUS
command to activate the blinker.
When an alarm condition is detected in ARM STATE
| –
|
PARAMETRIC ………………………………by LIN
BUS command
|
| –
|
IGN Key …………………………………… by
LIN BUS command
|
| –
|
EXTERNAL SENSOR……………………… by INTERNAL
LIN command
|
| –
|
VEHICLE BATTERY TAMPERING……………by POWER SUPPLY
Monitoring
|
| –
|
INTERNAL LIN TAMPERING FUNCTION……by heartbeat Monitoring
If the alarm cause is not removed, the ALARM CYCLE is
repeated after an ALARM PAUSE.
The ALARM CYCLE duration is 27±0.5 sec and ALARM PAUSE
is 5±0.5 sec.
During the ALARM CYCLE, it is possible to DISARM by
BCM specific LIN BUS command.
|

Protection
| –
|
PERIMETRIC – IGN KEY
The SIREN protects the vehicle against perimetric opening
and ignition key activation attempts.
The BCM sends a specific command to the SIREN if a door/hood/tgate
are opened or theignition is turn-on.
If the SIREN is in ARM state or PARTIAL ARM state, it
goes to ALRAM state. If the alarm condition remains
the SIREN will go again to the ALARM state until the
alarm counter is rolled off(total 9 ALARM cycles of
27.5sec and 8 ALARM pause of 5sec, internal memory default)
|
| –
|
INTERNAL LIN Tampering
If the communication is interrupted during ARM State,
the SIREN goes to ALARM state. The the alarm condition
remains, the SIREN will goes again to ALARM state until
the alarm counter is rolled off(total 9 ALARM cycles
of 27.5sec and 8 ALARM pause of 5sec, internal memory
default)
|
| –
|
Vehicle Battery Tampering
If one or both power supply wire(B+ and/or GND) are
removed during ARM state or PARTIALARM state,the SIREN
goes to ALARM state.
The the alarm condition remains, the SIREN will goes
again to ALARM state until the alarm counter is rolled
off(total 8 ALARM cycles of 26ec and 7 ALARM pause of
14sec, internal memory default)
|
| –
|
Internal Battery Connection
The SIREN is a self-powered system with internal back-up
battery(primary lithium type Typical capacity 1400mAh)
The external power supply is always monitored and the
behaviour of the system will change According to the
