Vehicle Security System Activation

VEHICLE SECURITY SYSTEM ACTIVATION

Pattern A
With all doors closed (including hood and trunk lid), if the key is used to lock doors, smart entrance control unit terminal 41 receives a ground signal:
- from terminal L of the front door key cylinder switch LH
- to terminal E of the front door key cylinder switch LH
- through body grounds M28 and M54.

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 open, if lock/unlock switch is used to lock doors, smart entrance control unit terminal 23 receives a ground signal:
- from terminal 14 of main power window and door lock/unlock switch
- to terminal 3 of main power window and door lock/unlock switch, or
- from terminal 1 of door lock/unlock switch RH
- to terminal 5 of door lock/unlock switch RH
- through body grounds M28 and M54.

With any door open, if the key is used to lock doors, smart entrance control unit terminal 41 receives a ground signal:
- from terminal L of the front door key cylinder switch LH
- to terminal E of the front door key cylinder switch LH
- through body grounds M28 and M54.

If these signals and lock signal from keyfob are received by the smart entrance control unit and ground signals of terminals 36 and 37 are interrupted (both front doors locked), 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 31 supplies ground to terminal 2 of the security indicator lamp.

The security indicator lamp will illuminate for approximately 30 seconds and then blink every 2.6 seconds.

Now the vehicle security system is in armed phase.
