Initial Condition To Activate The System

WARNING: This page is about a different car, the 2003 Nissan Murano. 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, hood and back door.

To activate the vehicle security system, BCM must receive signals indicating the doors, hood and back door are closed and the doors are locked by key fob.

When a door is open, BCM terminal 10 or 14 receives a ground signal from each door switch. (Auxiliary circuit.)

When a door is open, unified meter and A/C amp. terminal 7 (passenger side door), 8 (driver side door), 17 (rear RH door), 18 (rear LH door) receives a ground signal from each door switch.

The unified meter and A/C amp. then sends a signal to the BCM through the CAN SYSTEM.

When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 74 receives a signal from terminal 14 of power window main switch.

When front door RH is unlocked by power window switch (passenger side) (door lock and unlock switch), BCM terminal 74 receives a signal from terminal 16 of front power window switch (passenger side).

When the hood is open, IPDM E/R receives a ground signal

from hood switch terminal 1
to IPDM E/R terminal 51
through body grounds E13, E26 and E28.

The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM. When the back door is open, BCM terminal 18 receives a ground signal

from terminal 1 of the back door switch
through body grounds B7 and B20.
