How the Circuit Works
Arming the Security System
The security system can be armed:
r By pressing the remote control LOCK button
(if equipped)
. 20 seconds atter closing all doors (C)UDX only)
Arming with the Transmitter
The security system can be armed by removing the
ignition key from the ignition switch, closing all
doors and the trunk, and pressing the LOCK button
on the transmitter. When you arm the system in this
way, the remote control LED comes on, the status
LED flashes once per second, the parking lights
flash once. the doors lock. and the horn sounds
once if the beeo sound mode is on.
Passive Arming (CX and Dx only)
When you turn the ignition to OFF, remove the
ignition key from the ignition switch, and close all
the doors and the trunk; the system will
automatically arm itself 20 seconds after the trunk
or last door is closed. When you arm the system
this way, the status LED tlashes 4 times per second
during the exit delay time, and once per second
after the system is armed; the parking lights will
flash once to confirm that the system is armed.
Triggering the Alarm
Atter you've armed the system, it will trigger the
alarm if any door or the trunldhatch is opened. lf the
battery is disconnected when the system is armed or
in the alarm mode, reconnecting it will immediately
trigger the alarm. When the alarm is triggered, the
following will occur for 30 seconds:
. the horn sounds
o the parking lights flash once per second
. the status LED flashes hvice oer second
. the starter is disabled
After 30 seconds, the alarm will stop and the
system will rearm. Pressing the transmitter
UNLOCK button will disarm the svstem.
tlr
133-13
Disarming the System without the Remote
Transmitter (HX, LX, and EX)
You can disarm the system by turning the ignition
switch to ON (ll) and pressing the disarm/valet
switch on the right side ol the stereo tuner face. The
disarm switch will also disarm the svstem after the
system has been triggered.
Disarming the System with the Remote
Transmitter (Hx, Lx, Ex, DX-V, and Si)
Pressing the transmitter UNLOCK button will disarm
the system. The parking lights llash t\ivice if the
alarm has not been tnggered. The parking lights
flash three times if the alarm has been triggered.
The driver's door will unlock. lf you press the unlock
button twice, it will unlock all doors. lf a door is not
opened within 30 seconds, the system will lock all
doors and rearm.
Disarming the System (CX and DX only)
lf the system arms itself, there is a 20 second delay
after you open a door before the alarm will trigger.
To disarm the system in this mode, simply turn the
ignition switch to the ON position
ldentitying Tripped Sensors
The system identifies which sensor trips the alarm
by flashing the status LED. To display the trip
sensor flash code, press the disarm/valet switch 3
times within 5 seconds after the system has been
disarmed. The status sensor will blink according to
the followino codes:
SensorsNumber of Flashes
Door
TrunldHatch
System Switches
1 blink, pause, repeat
2 blinks, pause, repeat
3 blinks, pause, repeat
For further operating instructions, see the security
syslem owner's manual.
