Initial Condition To Activate The System
WARNING: This page is about a different car, the 2005 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
The operation of the vehicle security system is controlled by the doors and trunk lid.
To activate the vehicle security system, BCM must receive signals indicating the doors and trunk lid are closed and the doors are locked.
When a door is open, BCM terminal 12, 13, 47 or 48 receives a ground signal from each door switch.
When front door LH is unlocked, BCM terminal 22 receives a signal from terminal 14 of main power window and door lock/unlock switch.
- When front door RH is unlocked, BCM terminal 22 receives a signal from terminal 11 of power window and door lock/unlock switch RH.
- The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the trunk lid is open, BCM terminal 42 receives a ground signal
- from terminal 1 of the trunk lamp switch and trunk release solenoid
- through body grounds B7 and B19.
