Antitheft and Alarm Systems: Description and Operation

1. Operation flow
2. Setting the theft warning system Initial condition
1. Close all doors.
2. Close hood and trunk lid.
Disarmed phase
The theft warning system is in the disarmed phase when any door(s), hood or trunk lid is opened. The security indicator lamp blinks every second.
Pre-armed phase and armed phase
The theft warning system turns into the "pre-armed" phase when hood, trunk lid and all doors are closed and locked by key or multi-remote controller. (The security indicator lamp illuminates.)
After about 30 seconds, the system automatically shifts into the "armed" phase (the system is set). (The security indicator lamp blinks every 2.4 seconds.)
3. Canceling the set theft warning system
When the following (a) or (b) operation is performed, the armed phase is canceled.
a. Unlock the doors with the key or multi-remote controller.
b. Open the trunk lid with the key. When the trunk lid is closed after opening the trunk lid with the key, the system returns to the armed phase.
4. Activating the alarm operation of the theft warning system
Make sure the system is in the armed phase. (The security indicator lamp blinks every 2.4 seconds.) When the following operation (a), (b) or (c) is performed, the system sounds the horns and flashes the headlamps for about 2.5 minutes. (At the same time, the system disconnects the starting system circuit.)
a. Engine hood, trunk lid or any door is opened before unlocking door with key or multi-remote controller.
b. Door is unlocked without using key or multi-remote controller.
c. Trunk lid key cylinder is removed, by being punched, for example.
Power is supplied at all times
^ through 7.5 A fuse [No. (40), located in the fuse block (J/B)]
^ to security indicator lamp terminal (2).
With the ignition switch in the ACC or ON position, power is supplied
^ through 7.5 A fuse [No. (19), located in the fuse block (J/B)]
^ to Body Control Module (BCM) terminal (25).
BCM is connected to LCU01, LCU02, LCU03, LCU04 and LCU05 as DATA LINES A-1 or A-2.

INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the theft warning system is controlled by the doors, hood and trunk lid.
To activate the theft warning system, the BCM must receive signals indicating the doors, hood and trunk lid are closed and the doors are locked.
When a door is open, BCM terminal (35) receives a ground signal from each door switch.
When a front door is unlocked, door LCU01 or 02 terminal (4) receives a ground signal from terminal (2) of each door unlock sensor.
When a rear door is unlocked, door LCU03 or 04 terminal (5) receives a ground signal from terminal (2) of the door unlock sensor.
When the hood is open, BCM terminal (36) receives a ground signal
^ from terminal (1) of the hood switch
^ through body grounds (E5) and (E30).
When the trunk lid is open, BCM terminal (37) receives a ground signal
^ from terminal (1) of the trunk room lamp switch
^ through body grounds (B16) and (B19).
When the trunk lid key cylinder is removed by being punched, for example, BCM terminal (26) receives a ground signal from removed tamper switch.
When the doors are locked with key or multi-remote controller and none of the described conditions exist, the theft warning system will automatically shift to armed phase.

THEFT WARNING SYSTEM ACTIVATION (With key or remote controller used to lock doors)
If the key is used to lock doors, LCU01/02 terminal (6) receives a ground signal
^ from terminal (1) of the door key cylinder switch
^ through body grounds (M13), (M73) and (M111).
If this signal or lock signal from remote controller is received by the LCU01/02 or LCU05, the theft warning system will activate automatically.
Once the theft warning system has been activated, BCM terminal (2) supplies ground to terminal (1) of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blink.
Now the theft warning system is in armed phase.

THEFT WARNING SYSTEM ALARM OPERATION
The theft warning system is triggered by
^ opening a door
^ opening the trunk lid
^ opening the hood
^ removing trunk lid key cylinder
^ unlocking door without using the key or multi-remote controller.
Once the theft warning system is in armed phase, if BCM or LCU receives one of the following ground signals, the theft warning system will be triggered. The headlamps flash and the horn sounds intermittently, and the starting system is interrupted.
^ door switch open signal at BCM terminal (35)
^ trunk room lamp switch open signal at BCM terminal (37)
^ hood switch open signal at BCM terminal (36)
^ front door unlock signal at LCU01/02 terminal (4)
^ rear door unlock signal at LCU03/04 terminal (5)
^ trunk lid key cylinder removed signal at BCM terminal (26)
Power is supplied at all times
^ through 10 A fuse [No. (17), located in the fuse block (J/B)].
^ to theft warning relay terminal (1).
If the theft warning system is triggered, ground is supplied
^ from terminal (22) of the BCM
^ to theft warning relay terminal (2).
With power and ground supplied, power to the clutch interlock relay (M/T models) or inhibitor relay (A/T models) is interrupted. The starter motor will not crank and the engine will not start.
Power is supplied at all times
^ through 7.5 A fuse (No. (65) located in fuse and fusible link box)
^ to theft warning lamp relay terminal (1)
^ to theft warning horn relay-2 terminal (1).
When the theft warning system is triggered, ground is supplied intermittently
^ from terminal (21) of the BCM
^ to theft warning lamp relay terminal (2) and
^ to theft warning horn relay-2 terminal (2).
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate it the vehicle is tampered with again.

THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door or the trunk lid must be unlocked with the key or remote controller.
When the key is used to unlock a door, LCU01/02 terminal (5) receives a ground signal
^ from terminal (2) of the door key cylinder switch.
When the key is used to unlock the trunk lid, BCM terminal (10) receives a ground signal from terminal (1) of the trunk lid key cylinder switch.
When the BCM/LCUs receives either one of these signals or unlock signal from remote controller, the theft warning system is deactivated. (Disarmed phase)

PANIC ALARM OPERATION
Multi-remote control system may or may not operate theft warning system (horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently.
^ from BCM terminal (21)
^ to theft warning lamp relay terminal (2) and
^ to theft warning horn relay-2 terminal (2).
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when LCU05 (multi-remote control unit) receives any signal from multi-remote controller.
