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.
BCM receives a UNLOCK signal from key fob. BCM unlocks all doors with input of UNLOCK signal from key
fob.
Hazard Reminder
When the doors are locked or unlocked by key fob, supply power to hazard warning lamp flashes as follows

LOCK operation: 3 or 4 mode (flash once)

UNLOCK operation: 2 or 4 mode (flash twice)
The hazard reminder has 1, 2, 3 or 4 mode

Auto lock function signal is sent for operation when any of the following signals are not sent within 30 seconds
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”.

INTERIOR ROOM LAMP" .
CAN Communication System DescriptionBIS000WG
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 UnitBIS000WH
