OPERATED PROCEDURE
Power Door Lock Operation
BCM locks all doors with receiving 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.
Hazard and Horn Reminder
Power is supplied at all times
●
to horn relay terminal 2
●
through 10A fuse (No. 32, located in the fuse and fusible link box).
When BCM receives LOCK or UNLOCK signal from key fob with all doors closed, BCM sends horn chirp sig-
nal to IPDM E/R.
IPDM E/R grounds horn relay
●
to horn relay terminal 1
●
through IPDM E/R terminal 51, and
●
to BCM terminals 45 and 46 from hazard warning lamp system
Horn relay is now energized, and hazard warning lamp flashes and horn sounds as a reminder.
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
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
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”.

Room Lamp and Keyhole Illumination Operation
When the following conditions come:
●
condition of room lamp switch is DOOR position;
●
door switch OFF (when all the doors are closed);
Remote keyless entry system turns on room lamp and key ring illumination (for 30 seconds) with input of
UNLOCK signal from key fob.
For detailed description, refer to
.
Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in ignition 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
For detailed description, refer to
BL-205, "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”.

CAN Communication System Description
AIS003CO
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.
