BURGLAR ALARM FUNCTION

BURGLAR ALARM

1. Basic Concept



The following functions are related to the RKE and burglar alarm systems.



Door locking



Door unlocking



PSD open/close (both for left and right)



PTG open/close



Panic



If IGN key is inserted into the key cylinder, the RKE transmitter functions are inoperative.



Door locking by RKE signal:



Whenever this signal is received, door LOCK pulse is always issued.



Hazard lamp flashes one time for 1 second depending on the burglar alarm state.



This signal will make the system possible to enter into the ARM state (or PREARM state
depending on the vehicle condition).



Door unlocking by RKE signal.



Whenever this signal is received, door UNLOCK pulse is always issued.



Hazard lamp flashes two times whenever the key fob unlock signal is received.



This signal will make the system possible to enter into the DISARM or 30sec DELAY state
depending on Condition A is true or not.



LH or RH PSD open/close by RKE signal.



Only with the information received by RKE, the burglar alarm system cannot distinguish the
OPEN signal from CLOSE signal.



RAM will pass this signal to LH PSD and RH PSD then the burglar alarm state is decided
depending on the vehicle condition.



PTG open/close



Only with the information received by RKE, the burglar alarm system cannot distinguish the
OPEN signal from CLOSE signal.



RAM will pass this signal to PTG module then the burglar alarm state is decided depending
on the vehicle condition.



Panic by key fob



Whenever this signal is received, the PANIC function is activated (unless the system is
already in an ALARM state).



Mechanical key on the driver door, assist door and tail gate door



It is possible to ARM or DISARM the system.

ARM MODE



If 30 second timer is elapsed without any changes from the ARM WAIT mode, then system goes to ARM
mode.



Whenever RKE lock signal is received in the ARM state, then the system makes a hazard flash (1 second)
and sends a door lock pulse.

PREARM MODE



If the vehicle is locked using the RKE transmitter or the door lock cylinder, and one or more doors are in
an OPEN state, the system issues a LOCK pulse and enters a PREARM state. "In the PREARM state, the
hazard lamps do not flash".



If all doors are closed in the PREARM state, the system enters ARM WAIT mode, and the hazard lamps

will flash once.



During PREARM state, if f key reminder switch is ON & IGN 1 & IGN 2 are turned on in this state, the
system immediately goes to DISARM state

ARM WAIT MODE



The ARM WAIT mode is active for 30 seconds. If any entrance (hood, doors, tailgate) is opened, any
lock knob is moved to an UNLOCK state, or the ignition switch is turned ON, the system will
immediately enter DISARM mode. The system will enter ARM state if none of the previously mention
conditions occur during the 30-second ARM WAIT mode.

DISARM MODE



If RKE unlock signal is received, then UNLOCK output is issued together with the flashing of hazard
lamp (two times) and the system enters into the DISARM condition.



If mechanical key switch unlock signal is received, then UNLOCK output is issued for 500ms and the
system enters into the DISARM condition.



When entering into DISARM from ALARM state, current alarm will be cancelled and burglar alarm relay
drive output is turned off.



When RKE unlock signal is received again in the DISARM state, UNLOCK output is issued again and
hazard lamp is flashed also (two times).

ALARM MODE



If one or more of entrances are opened in the ARM or REARM state, then Burglar alarm relay drive
output is turned ON in order to inhibit the start condition, and hazard lamp and siren are activated for 3
consecutive cycle of 27 seconds duration.



Siren output and hazard lamp should be synchronized to get the same output period.



Even though all the doors are closed during alarm, alarm continues to operate it for the remaining time.



When there is a new attack (with one of the entrance is still open) in the vehicle after completing the
alarm output, alarm should not be started again.

AFTER ALARM STATE



If ALARM cycle is elapsed, the system goes into AFTER ALARM state.



During this state,



Burglar alarm relay drive output maintains ON.



Siren and hazard lamp output are stopped.



If another entry is opened during the AFTER ALARM state, the burglar alarm relay drive output remains
ON, but the siren will not be re-activated.

REARM STATE



If all entrances are is closed during AFTER ALARM state, the system goes into REARM state.

BATTERY REMOVAL



If the battery is removed with the system in the ARM state, the system will be placed into the ARM state
upon battery reconnect.



The ALARM state will be re-activated if the battery is disconnected, then reconnected, with the system in
an ALARM state.



If the battery is disconnected and reconnected with the system in AFTER ALARM state, the alarm will be
re-activated.



The system will enter DISARM mode if the battery is disconnected during the ALARM WAIT state.
