ACTIVE ARMING MODE
(a) Active arming mode:
This system operates as described in the diagram below when one of the items
for each condition is met.
HINT:
The term "all doors" used in this section refers to the driver door, front passenger
door, rear door LH and rear door RH.
|
Condition
|
Item
|
|
Condition [1]
|
In disarmed state 1, when the ignition switch is off and the key is not
in the key cylinder, the system state is switched if the following condition
is met:
- With all doors and the engine hood closed, all doors are locked
by wireless operation or key linked power door lock operation.
In disarmed state 1, when the ignition switch is off, the key is not
in the key cylinder, the engine hood is closed and all doors are locked,
the system state is switched if the following condition is met:
- The state changes from any of the doors being opened to all doors
being closed.
|
|
Condition [2]
|
- Allow approximately 30 seconds to elapse.
|
|
Condition [3]
|
One of the following conditions is met:
- All doors are unlocked by wireless operation or key linked power
door lock operation.
- Any door is unlocked.
- Any door is opened.
- The key is inserted to the key cylinder.
- The battery is reconnected.
|
|
Condition [4]
|
One of the following conditions is met:
- The engine hood is opened when the engine hood is closed.
- Any door is opened when all doors are closed.
- Any door is unlocked when all doors are locked.
- The glass breakage sensor detects that glass is broken.*
HINT:
When the glass breakage sensor detects the glass is broken (1st time),
the sensor will set off an alarm for 20 seconds (pre-alarm). If the
glass breakage sensor detects that more glass is broken (2nd time or
more), the system state is switched to the alarm sounding state. If
the glass breakage sensor does not detect 2nd glass breakage and 20
seconds elapse from 1st time, the system state stays the armed state.
- The ignition switch is turned to ON when the key is not in the key
cylinder.
|
|
Condition [5]
|
One of the following conditions is met:
- The ignition switch is turned to ON and the engine is running at
550 rpm for more than 2 seconds.
- All doors are unlocked by wireless operation or key linked power
door lock operation.
- The ignition switch is turned to ACC or ON when the key is in the
key cylinder.
|
|
Condition [6]
|
- After approximately 57 seconds, the alarm stops and the system returns
to the armed state.
|
|
Condition [7]
|
- The engine hood is closed with all the doors closed.
|
|
Condition [8]
|
One of the following conditions is met:
- Any door is unlocked when all doors are locked.
- Any door is opened.
- The ignition switch is turned to ACC or ON.
- The battery is reconnected.
- All doors are unlocked by wireless operation or key linked power
door lock operation.
|
|
Condition [9]
|
In disarmed state 1, when the ignition switch is off and the key is not
in the key cylinder, the system state is switched if the following condition
is met:
- With all doors closed and the engine hood open, all doors are locked
by wireless operation or key linked power door lock operation.
In disarmed state 1, when the ignition switch is off, the engine hood
is open and all doors are locked, the system state is switched if the following
condition is met:
- The state changes from any of the doors being opened to all doors
being closed.
|
|
Condition [10]
|
- The engine hood is opened.
|
- *: w/ Glass Breakage Sensor
FORCED DOOR LOCK CONTROL
(a) The forced door lock control prevents the vehicle from being tampered with.
Immediately after a door is unlocked (armed state), all doors are forced to lock
by a forced door lock signal.
(1) If the following conditions are met, the forced door lock control is operated.
- The theft deterrent system is in the armed state.
- Any door is unlocked.
ALARM MEMORY FUNCTION
(a) If the alarm is set off (tampering is detected) while the theft deterrent
system is in the armed state, it will be stored by the alarm memory function. Whenever
the theft deterrent system is canceled, the alarm memory function causes the taillights
to light up for 2 seconds in order to inform the user that the alarm has been set
off.
(1) Condition that cause the taillights to light up for 2 seconds:
The theft deterrent system has entered the alarm sounding state (tampering has
been detected) at least once.
HINT:
Active arming mode: See Active Arming Mode.
PANIC ALARM CONTROL
(a) Panic alarm control makes it possible to voluntarily set off the panic alarm
by pressing the panic switch on the electrical key transmitter sub-assembly.
(1) Conditions that cause panic alarm control to set off the panic alarm:
The panic switch on the electrical key transmitter sub-assembly is pressed under
the following conditions:
- The ignition switch is off.
- The theft deterrent system is not in the alarm sounding state.
(2) Conditions that cause the panic alarm control to shut off the alarm:
Any of the following conditions is met during panic alarm control operation:
- The ignition switch is turned to ON.
- The panic switch is pressed again.
- Any of the switches on the electrical key transmitter sub-assembly (lock/unlock)
is pressed.
- The panic alarm ends (approximately 57 seconds have elapsed).
- The theft deterrent system switches to the alarm sounding state. Under this
condition, the theft deterrent system controls the alarm rather than the panic
alarm control. In order to cancel this alarm, refer to the theft deterrent system
alarm sounding state cancellation procedure.
SECURITY INDICATOR LIGHT OUTPUT
(a) According to the state of the theft deterrent system, the main body ECU (multiplex
network body ECU) outputs a signal to turn the security indicator light on. However,
some of the actual lighting conditions of the security indicator light are different
from the output signals of the main body ECU (multiplex network body ECU).
