OPERATED PROCEDURE
Power Door Lock Operation
BCM receives a LOCK signal from key fob. BCM locks all doors with input of LOCK signal from key fob.
When an UNLOCK signal is sent from key fob once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from key fob again within 5 seconds, all other door will be unlocked.
Power door lock operation mode can be changed using “DOOR LOCK-UNLOCK SET” mode in “WORK SUP-
PORT” of “POWER DOOR LOCK SYSTEM”.
Refer to BL-65, "
Work Support" .
Power door lock operation mode can be changed also on the display.
Hazard and Horn Reminder
When the doors are locked or unlocked by key fob, power is supplied to hazard warning lamp and lamp flash
as follows

LOCK operation: C mode (flash twice) or S mode (flash twice)

UNLOCK operation: C mode (flash once) or S mode (do not flash)
BCM outputs to IPDM E/R for horn reminder signal as DATA LINE (CAN H line and CAN L line).
The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).
Operating function of hazard and horn reminder
Hazard and horn reminder do not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-II
Hazard and horn reminder can be changed using “MULTI ANSWER BACK SET” mode in “WORK SUPPORT”.
Refer to BL-65, "
Work Support" .
Without CONSULT-II
When LOCK and UNLOCK signals are sent from the key fob for more than 2 seconds at the same time, the
hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:
Auto Door Lock Operation
Auto lock function signal is sent for operation when any of the following signals are not sent within 1 minute
after the unlock signal is sent from the key fob:

when door switch is turned ON for open.

when the key switch is turned ON.

when the lock signal is sent from the key fob.
Auto door lock mode can be changed using “AUTO LOCK SET” mode in “WORK SUPPORT”.
Refer to BL-65, "
Work Support" .
Auto door lock mode can be changed also on the display.

Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn and
headlamp intermittently with input of PANIC ALARM signal from key fob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
Panic alarm operation mode can be changed using “PANIC ALARM SET” mode in “WORK SUPPORT”.
Refer to BL-65, "
Work Support" .
For detailed description, refer to BL-180, "
VEHICLE SECURITY (THEFT WARNING) SYSTEM" .
Keyless Power Window Down (Open) Operation
When key fob unlock switch is turned ON with ignition switch OFF, and key fob unlock switch is detected to be
on continuously for 3 seconds, the driver's door and passenger's door power windows are simultaneously
opened.
Power window is operated to open and the operation continues as long as the key fob unlock switch is
pressed.
Keyless power window down operation mode can be changed using “PW DOWN SET” mode in “WORK SUP-
PORT”. Refer to BL-65, "
Work Support"
Room Lamp and Ignition Key Ring Illumination Operation
When the following conditions come:

condition of interior lamp switch is DOOR position;

door switch OFF (when all the doors are closed);
Remote keyless entry system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from key
fob. For detailed description, refer to LT- 1 5 6 , "
INTERIOR ROOM LAMP" .
CAN Communication System DescriptionNIS001MJ
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS001MK
Refer to LAN-32, "CAN Communication Unit" .
