POWER SUPPLY AND GROUND
Power is supplied at all times
- through 7.5 A fuse [No. 5, located in the fuse block (J/B)]
- to security indicator lamp terminal 1.
Power is supplied at all times
- through 30 A fusible link (letter d, located in the fuse and fusible link box)
- to smart entrance control unit terminal 11.
With the ignition switch in the ACC or ON position, power is supplied
- through 7.5 A fuse [No. 10, located in the fuse block (J/B)]
- to smart entrance control unit terminal 21.
Ground is supplied
- to smart entrance control unit terminal 16
- through body grounds M15, M71 and M76.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, engine hood and trunk lid.
To activate the vehicle security system, the smart entrance control unit must receive signals indicating the doors, engine hood and trunk lid are closed and the doors are locked. When a door is open, smart entrance control unit terminal 28, 29 or 40 receives a ground signal from each door switch.
When a door is unlocked, smart entrance control unit terminal 26, 36 or 37 receives a ground signal from terminal 4 of each door unlock sensor. When the engine hood is open, smart entrance control unit terminal 27 receives a ground signal
- from terminal 1 of the hood switch
- through body grounds E9 and E28.
When the trunk lid is open, smart entrance control unit terminal 38 receives a ground signal
- from terminal 1 of the trunk room lamp switch
- through body grounds B109 and B110.
When the doors are locked with key or multi-remote controller and none of the described conditions exist, the vehicle security system will automatically shift to armed mode.
VEHICLE SECURITY SYSTEM ACTIVATION (WITH KEY OR REMOTE CONTROLLER USED TO LOCK DOORS)
If the key is used to lock doors, terminal 41 receives a ground signal
- from terminal 1 of the key cylinder switch (driver side)
- from terminal 3 of the front door key cylinder switch (passenger side)
- through body grounds M15, M71 and M76
If this signal or lock signal from remote controller is received by the smart entrance control unit, the vehicle security system will activate automatically
Once the vehicle security system has been activated, smart entrance control unit terminal 31 supplies ground to terminal 2 of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blink.
Now the vehicle security system is in armed phase.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
- opening the door without using the key
- opening the engine hood or the trunk lid
- unlocking the door without using the key
Once the vehicle security system is in armed phase, if the smart entrance control unit receives a ground signal at terminal 26, 36, 37 (door unlock sensor), 28, 29, 40 (door switch), 38 (trunk room lamp switch) or 27 (hood switch), the vehicle security system will be triggered. The headlamps flash and the horn sounds intermittently.
Power is supplied at all times
- through 10 A fuse (No. 36, located in fuse and fusible link box)
- to vehicle security lamp relay terminal 1 and
- to horn relay terminals 1 and 3
- through 10 A fuse (No. 41, located in fuse and fusible link box)
- to horn relay terminal 6.
When the vehicle security system is triggered, ground is supplied intermittently
- from terminal 4 of the smart entrance control unit
- to vehicle security lamp relay terminal 2 and
- from terminal 19 of smart entrance control unit
- to horn relay Terminal 2.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, the door or the trunk lid must be unlocked with the key or remote controller.
When the key is used to unlock the door, smart entrance control unit terminal 30 receives a ground signal
- from terminal 3 of the front door key cylinder switch (driver side)
- from terminal 1 of the front door key cylinder switch (passenger side)
When the key is used to open the trunk lid, smart entrance control unit terminal 42 receives a ground signal from terminal 1 of the trunk lid key cylinder switch.
When the smart entrance control unit receives either one of these signals or unlock signal from remote controller, the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Multi-remote control system may or may not operate vehicle security system (horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently.
- from smart entrance control unit terminal 4
- to vehicle security lamp relay terminal 2 and
- from smart entrance control unit terminal 19
- to terminal 2 of horn relay.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when smart entrance control unit receives any signal from multi-remote controller.
