Initial Condition To Activate The System
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, Intelligent Key or ignition key.
When a door is open, BCM terminal 12 (passenger side door), 13 (rear RH door), 62 (driver side door), 63 (rear LH door) receives a ground signal from each door switch.
When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 14 of power window main switch with power window serial link.
When front door RH is unlocked by front power window switch (passenger side) (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 16 of front power window switch (passenger side) with power window serial link.
When the hood is open, IPDM E/R receives a ground signal
- to IPDM E/R terminal 56
- through hood switch terminal 2
- through hood switch terminal 1
- through body grounds E21, E50 and E51.
The IPDM E/R then sends a signal to the BCM through the CAN SYSTEM.
When the back door is open,
- to BCM terminal 58
- through back door closure motor terminal 7
- through back door closure motor terminal 8
- through body grounds B15 and B45.
