INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors hood and trunk lid.
Pattern A
To activate the vehicle security system the smart entrance control unit must receive signals indicating the doors hood and trunk lid are closed.
When a door is open smart entrance control unit terminal 1 2 or 3 receives a ground signal from each door switch.
When the hood is open smart entrance control unit terminal 6 receives a ground signal
- from terminal 1 of the hood switch
- through body grounds Eli E22 and E53.
When the trunk lid is open smart entrance control unit terminal 13 receives a ground signal
- from terminal 1 of the trunk room lamp switch
- through body grounds T6 and T8.
When smart entrance control unit receives LOCK signal from key cylinder switch or keyfob and none of the described conditions exist the vehicle security system will automatically shift to armed mode.
Pattern B
To activate the vehicle security system the smart entrance control unit must receive signal indicating any door (including hood and trunk lid) is opened.
When the front doors are locked with key lock/unlock switch or keyfob and then all doors are closed the vehicle security system will automatically shift to armed mode.
VEHICLE SECURITY SYSTEM ACTIVATION
Pattern A
With all doors (including hood and trunk lid) closed if the key is used to lock doors front power window main switch terminal 6 receives a ground signal
- from terminal 3 of the key cylinder switch LH
- through body grounds M9, M25 and M87.
If this signal or lock signal from keyfob is received by the smart entrance control unit the vehicle security system will activate automatically.
NOTE: Vehicle security system can be set even though all doors are not locked.
Pattern B
With any door (including hood and trunk lid) open if lock/unlock switch is used to lock doors terminal 33 receives a ground signal
- from terminal 8 of lock/unlock switch LH or
- from terminal 11 of lock/unlock switch RH
- through body grounds M9, M25 and M87 or
With any door (including hood and trunk lid) open if the key is used to lock doors front power window main switch terminal 6 receives a ground signal
- from terminal 3 of the key cylinder switch LH
- through body grounds M9, M25 and M87.
If these signals and lock signal from keyfob are received by the smart entrance control unit ground signals of terminals 1 2 and 3 are interrupted and all doors are closed the vehicle security system will activate automatically.
NOTE: Vehicle security system can be set even though the rear door is not locked.
Once the vehicle security system has been activated smart entrance control unit terminal 38 supplies ground to terminal 5 of the security indicator lamp.
The security lamp will illuminate for approximately 30 seconds and then blinks every 2.6 seconds.
Now the vehicle security system is in armed phase.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
- opening a door
- opening the hood or the trunk lid
- detection of battery disconnect and connect.
Once the vehicle security system is in armed phase if the smart entrance control unit receives a ground signal at terminal 1 2 3 (door switch) 13 (trunk room lamp switch) or 6 (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 61 located in fuse and fusible link box)
- to vehicle security horn relay-1 terminals 1 and 3 and
- to vehicle security horn relay-2 terminal 1
- through 10 A fuse (No.57 located in fuse and fusible link box)
- to horn relay terminal 2.
Power is also supplied at all times
- through 15 A fuse (No.68 located in fuse and fusible link box)
- to headlamp relay LH terminal 3
- through 20 A fuse (No.54 located in fuse and fusible link box)
- to headlamp relay LH terminals 1 and 6
- through 15 A fuse (No.69 located in fuse and fusible link box)
- to headlamp relay RH terminal 3 and
- through 20 A fuse (No.55 located in fuse and fusible link box)
- to headlamp relay RH terminals 1 and 6.
When the vehicle security system is triggered ground is supplied intermittently
- to headlamp LH relay terminal 2 from smart entrance control unit terminal 21 and
- to headlamp RH relay terminal 2 from smart entrance control unit terminal 59
- through smart entrance control unit terminals 43 and 64.
When headlamp relays (LH and RH) are energized and then power is supplied to headlamps (LH and RH).
The headlamps flash intermittently.
When the vehicle security system is triggered ground is supplied intermittently
- from smart entrance control unit terminal 42
- to vehicle security horn relay-2 terminal 2.
When vehicle security horn relay-2 is energized ground is supplied intermittently
- to vehicle security horn relay-1 terminal 2 and
- to horn relay terminal 1.
When vehicle security horn relay-1 and horn relay are energized then power is supplied to vehicle security horn and horn.
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 a door or trunk lid must be unlocked with the key or keyfob. When the key is used to unlock the door front power window main switch terminal 19 receives a ground signal
- from terminal 1 of the LH key cylinder switch.
When the key is used to open the trunk lid smart entrance control unit terminal 12 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 keyfob the vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote keyless entry system may or may not operate vehicle security system (horn and headlamps) as required.
When the remote keyless entry system (panic alarm) is triggered ground is supplied intermittently
- from smart entrance control unit terminal 42
- to vehicle security horn relay-2 terminal 2
- from smart entrance control unit terminal 21
- to headlamp LH relay terminal 2 and
- from smart entrance control unit terminal 59
- to headlamp RH relay terminal 2
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 25 seconds or when smart entrance control unit receives any signal from keyfob.
