DESCRIPTION
Operation Flow
Setting the Vehicle Security System
Initial condition

Ignition switch is in OFF position.
Disarmed phase

When hood, doors or trunk is open, the vehicle security system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.

When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4
seconds.
Pre-armed phase and armed phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (The security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door key cylinder switch or Intelligent Key, after hood, trunk and all
doors are closed.
2. Hood, trunk and all doors are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. Then, the system automatically shifts into the
“armed” phase.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
Revision: 2007 April2007 M35/M45
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 50A fusible link (letter F , located in the fuse and fusible link box)

to BCM terminal 55,

through 10A fuse [No. 21, located in the fuse block (J/B)]

to BCM terminal 42,

through 10A fuse [No. 71, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 78, located in the IPDM E/R]

to IPDM E/R internal CPU,

through 15A fuse [No. 37, located in the fuse block (J/B)]

to multi-function switch (security indicator) terminal 1.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in the fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through body grounds M16 and M70.
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.
