• to BCM terminal 38.
Ground is supplied• to BCM terminal 67
• through body grounds M57 and M61.
INITIAL CONDITION TO ACTIVATE THE SYSTEM
The operation of the vehicle security system is controlled by the doors and trunk (sedan).
To activate the vehicle security system, BCM must receive signals indicating the ignition switch is OFF, doors
and trunk (sedan) are closed and locked.
When a door or trunk (sedan) is open, BCM terminal 12, 13, 42, 43, 47 or 48 receives a ground signal from
each door or trunk switch. In addition to BCM, when back door is open, the Intelligent Key unit terminal 23
receives a ground signal from back door or trunk (sedan) through BCM terminal 30.
When front door LH is unlocked, BCM terminal 46 receives a signal from terminal 6 of main power window and
door lock/unlock switch.
When front door RH is unlocked, BCM terminal 46 receives a signal from terminal 2 of power window and door
lock/unlock switch RH.
VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
• Opening a door without using the key, keyfob or Intelligent Key.
• Opening trunk without using the key, keyfob or Intelligent Key (sedan).
The vehicle security system will be triggered once the system is in armed phase,
• when BCM receives a ground signal at terminals 12, 13, 47, 48 (front or rear door switch), terminal 42
(sedan, trunk switch) or terminal 43 (hatchback, back door switch).
When the vehicle security system is triggered, ground is supplied intermittently
• from IPDM E/R terminal 45
• to horn relay terminal 1.
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.
VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or trunk (sedan) must be unlocked with the key, keyfob or
Intelligent Key.
When the key is used to unlock the driver door, BCM terminal 7 receives signal
• from terminal 3 of the front door key cylinder switch LH.
When the key is used to open the trunk (sedan), BCM terminal 41 receives signal
• from terminal 1 of the trunk key cylinder switch.
When the BCM receives an unlock signal from keyfob, Intelligent Key, front door key cylinder switch LH or
trunk key cylinder switch (sedan), the vehicle security system is deactivated (Disarmed phase).
PANIC ALARM OPERATION
Intelligent Key and remote keyless entry system may or may not operate vehicle security system (horn and
headlamps) as required.
When the remote keyless entry system is triggered, ground is supplied intermittently

• to rear combination lamp LH terminal 1
• through grounds B7 and B19.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power
• through BCM terminal 61
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 (all models) and D402 (with hatchback).
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
• through 40A fusible link (letter g , located in fuse, fusible link and relay box)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57,
• through 10A fuse [No. 13, located in fuse block (J/B)]
• to combination meter terminal 27.
Ground is supplied
• to hazard switch terminal 1,
• to BCM terminal 67, and
• to combination meter terminals 21, 22 and 23
• through grounds M57 and M61.
When hazard switch is depressed, ground is supplied
• through hazard switch terminal 2
• to BCM terminal 29.
BCM then supplies power
• to front combination lamp LH terminal 4 and
• to rear combination lamp LH terminal 6
• through BCM terminal 60,
• to front combination lamp RH terminal 4 and
• to rear combination lamp RH terminal 6
• through BCM terminal 61.
Ground is supplied
• to front combination lamp LH and RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp LH terminal 1
• through grounds B7 and B19,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 and D402 (hatchback).
The BCM also supplies input to combination meter across the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination meter, which in turn supplies ground to the left and right
turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times
• through 40A fusible link (letter g , located in fuse, fusible link and relay box)
• to BCM terminal 70,
