Kia Sportage QL (2015-2019) Service Manual / Body Electrical System / Anti-theft System / Description and operation

Description
Anti-theft device
Block diagram

BCM : Arming/Disarming data output
SIREN : Siren ON when disconnecting the battery, TILT & UIP sensor input
OFF switch : Alarm function OFF
TILT sensor : Senses the vehicle angle
UIP (Ultrasonic Intrusion Protection) sensor : Senses any unauthorised entry
This system is designed to provide protection from unauthorised entry into the vehicle.
This system is operated in three stages:
"Armed" stage, "Theft-alarm" stage and "Disarmed" stage.
If triggered, the system provides an audible alarm with blinking of the hazard warning lights.
Function
1.
Siren
(1)
Power On/Off
To turn on the siren, a power supply it required. It saves its status in the internal memory before being removed from the car battery supply or siren/sensors connector. Make sure that the system is in DISARM state, otherwise it will go off using the internal battery.
(2)
Arming/Disarming
The system is armed by BCM specific command on LIN BUS
Conditions to ARM the SIREN
System in DISARM STATE
Ignition "OFF"
The system is disarmed by BCM specific command on LIN BUS
Conditions to ARM the SIREN
System in ARM STATE
System in ALARM STATE
(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 excludes it automatically (except for UIP and TILT sensors). It will be re-included in the protection when it returns to the correct condition. A continuous low power sound indicates the exclusion during Pre-Arm/INHIBITION time.
The INHIBITION time duration is 30 seconds starting from DISARM to ARM transition.
ARM STATE
In this state, the vehicle is fully protected.
Partical ARM STATE
In this state, the vehicle excluding the UIP and TILP sensors, is not fully protected.
ALARM STATE
In this state, the SIREN goes off using vehicle battery if present, otherwise its internal battery.
ALARM PAUSE STATE
The ALARM PAUSE STATE is the state between two consecutive ALARM STATES
(5)
Stabilization Time
The Stabilization Time is the time in which the external sensors (UIP and TILT) need to stabilize the function when the system is armed. The Stabilization time duration for UIP and TILT sensors is 30 seconds starting from DISARM to ARM transition.
(6)
Alarm Causes
The SIREN activates the sound and sends to the BCM a LIN BUS command to activate the blinker.
The ALARM SIREN will be activated when any of the alarm conditions 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 cause of alarm is not eliminated, the ALARM CYCLE will be repeated after an ALARM PAUSE.
The durations for the ALARM CYCLE and ALARM PAUSE are 27±0.5 seconds and 5±0.5 seconds respectively.
During the ALARM CYCLE, it can be DISARMED by BCM specific LIN BUS command.
(7)
Protection
PARAMETRIC – IGN KEY
The SIREN protects the vehicle against parametric opening and ignition key activation attempts.
The BCM sends a specific command to the SIREN if a door/hood/tailgate are opened or the ignition is turned on.
If the SIREN is in ARM state or PARTIAL ARM state, it will go into the ALARM state. If the alarm condition remains, the SIREN will go again into the ALARM state until the alarm counter has rolled off (total 9 ALARM cycles of 27.5 seconds and 8 ALARM pauses of 5 seconds by internal memory default).
INTERNAL LIN Tampering
If the communication is interrupted during ARM State, the SIREN will go into the ALARM state. If the alarm condition remains, the SIREN will go again into the ALARM state until the alarm counter has rolled off (total 9 ALARM cycles of 27.5 seconds and 8 ALARM pauses of 5 seconds by internal memory default).
Vehicle Battery Tampering
If one or both power supply wires (B+ and/or GND) are removed during ARM state or PARTIALARM state, the SIREN will go into the ALARM state.
If the alarm condition remains, the SIREN will go again into the ALARM state until the alarm counter has rolled off (total 8 ALARM cycles of 26 seconds and 7 ALARM pauses of 14 seconds by internal memory default).
Internal Battery Connection
The SIREN is a self-powered system with internal back-up battery (primary lithium type with typical capacity of 1,400 mAh). The external power supply is always monitored and the behaviour of the system will change according to the following table.
