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:
Condition | Item |
---|---|
Condition [1] | In disarmed state 1, when the engine switch is turned off, the system state is changed if the following condition is met:
In disarmed state 1, when the engine switch is off, the engine hood is closed and all doors are locked, the system state is changed if the following condition is met:
|
Condition [2] |
|
Condition [3] |
|
Condition [4] |
|
Condition [5] |
|
Condition [6] |
|
Condition [7] |
|
Condition [8] |
|
Condition [9] | In disarmed state 1, when the engine switch is turned off, the system state is changed if the following condition is met:
In disarmed state 1, when the engine switch is off, the engine hood is open and all doors are locked, the system state is changed if the following condition is met:
|
Condition [10] |
|
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.
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:
(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:
THEFT WARNING SIREN ASSEMBLY (w/o Security Horn Assembly)
(a) The theft warning siren assembly has an internal battery. If power to the theft warning siren assembly is interrupted or the communication line is open, the theft warning siren assembly detects it and sounds the alarm using the internal battery.
(b) The theft warning siren assembly has the following alarm controls: normal alarm control and open circuit alarm control. Under normal alarm control, the alarm sounds based on instructions from the main body ECU (multiplex network body ECU) whereas under open circuit alarm control, the theft warning siren assembly judges current security conditions and sounds the alarm by itself.
(1) Normal alarm control
The theft warning siren assembly sounds when the theft deterrent system is in the alarm sounding state and does not sound when the system is not in the alarm sounding state.
HINT:
If the communication between the theft warning siren assembly and main body ECU (multiplex network body ECU) is continuously interrupted for 70 seconds or more while the theft deterrent system is in the alarm sounding state, the theft warning siren assembly will stop sounding.
(2) Open circuit alarm control
The theft warning siren assembly changes between the disarmed state and armed state in accordance with the change of the theft deterrent system between the disarmed state and armed state. If the power source, ground or communication line becomes open while the theft warning siren assembly is in the armed state, the theft warning siren assembly will sound.
During the open circuit alarm sounding state, the theft warning siren assembly sounds intermittently for 27.5 seconds and then stops for 5 seconds. This pattern repeats a maximum of 9 times.
This intermittent sounding will stop when either of the following conditions is met:
1. The theft warning siren assembly changes to the disarmed state.
2. The circuit returns to normal.
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).
Output State of Theft Deterrent System | Security Indicator Light | |
---|---|---|
Output Signal from Main Body ECU (Multiplex Network Body ECU) | Actual Lighting Condition | |
Disarmed state (1), (2) | Off |
|
Arming preparation state | On | On |
Armed state | Off | Blinking |
Alarm sounding state | On | On |
Time | Security Indicator Light |
---|---|
0.125 sec. | On |
1.875 sec. | Off |
HINT:
When the immobiliser system is set, the security indicator light blinks during both the disarmed state and the armed state due to output signals from the immobiliser system.
