INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors, hood and trunk.
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk are
closed and the doors are locked by key fob.
When a door is open, 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 an unlock signal from terminal 14 of power window main switch with power window serial link.
When front door RH is unlocked by power window sub-switch (passenger side) (door lock and unlock switch),
BCM terminal 22 receives an unlock signal from terminal 16 of power window sub-switch (passenger side)
with power window serial link.
When front door key cylinder switch is in LOCK position, ground is supplied
●
to power window main switch terminal 4
●
through front door key cylinder switch terminals 6 and 4
●
through body grounds M16 and M70.
When the hood is open, IPDM E/R receives a ground signal
●
to IPDM E/R terminal 60
●
through hood switch terminal 2
●
through hood switch terminal 1
●
through body grounds E22, and E43.
The IPDM E/R then sends a signal to BCM via CAN communication line.
When the trunk is open, ground is supplied
●
to BCM terminal 57
●
through trunk room lamp switch terminal 1
●
through trunk room lamp switch terminal 2
●
through body grounds B402 and B405.
