INITIAL CONDITION TO ACTIVATE THE SYSTEM
To activate the vehicle security system, the smart entrance control unit must receive signals indicating the
doors and hood are closed and the doors are locked.
When a door is open, smart entrance control unit terminal 1, 2, or 3 (Crew Cab) receives a ground signal from
the corresponding door switch.
When the hood is open, ground is supplied
●

If this signal or lock signal from keyfob is received by the smart entrance control unit, the vehicle security sys-
tem will activate automatically.
Once the vehicle security system has been activated, smart entrance control unit terminal 38 supplies ground
