Preliminary CheckINFOID:0000000001327893
Remove the fuse No.18 for the back door cl osure with the back door closure inactive.
Check that the back door can be open / close normally.
CAUTION:
It is judged it is abnormal, disc ontinues closure operation, and drive lever returns to a neutral position
if not becoming full-latch within about three seconds after half-latch.
When this operation is done cont inuously three times, both back door closure and back door opener
switch are not operated because the func tion of back door closure is stopped.
Thing to reset power supply by pull ing out and opening fuse in that case.

Make sure the system is in the armed phase. (The security indicator lamp brinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, t he system sounds the horns and flashes the headlamps for
about 50 seconds.
1. Hood, back door or any door is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.
POWER SUPPLY
Power is supplied at all times
 through 10A fuse [No.19, located in the fuse block (J/B)]
 to security indicator lamp terminal 1.
 through 50A fusible link (letter M, located in the fuse and fusible link box)
 to BCM terminal 55.
 through 15A fuse [No.22, located in the fuse block (J/B)]
 to BCM terminal 42.
 through 15A fuse [No.34, located in the fuse and fusible link box]
 to horn relay terminal 2.
 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.
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.
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 s witch (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.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
 opening a door
 opening the back door
 opening the hood
 detection of battery disconnect and connect.
The vehicle security system will be triggered once the system is in armed phase,
When BCM receives a ground signal at terminals 12 (p assenger side door), 13 (rear RH door), 58 (back door),
62 (driver side door), 63 (rear LH door), or rece ives a signal from the IPDM E/R (hood switch).
When the vehicle security system is triggered,
ground is supplied intermittently from IPDM E/R terminals 38 and 60.
