VEHICLE SECURITY SYSTEM DEACTIVATION
To deactivate the vehicle security system, a door or the back door must be unlocked with the key or key fob.
When the key is used to unlock a door, BCM terminal 22 receives signal
●
from terminal 14 of the power window main switch (door lock and unlock switch).
When the BCM receives either one of these signals or unlock signal from key fob or key cylinder switch, the
vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
Remote control entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote control entry system is triggered, ground is supplied intermittently to both headlamp relay
and horn relay.
When headlamp relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied to
headlamps (LH and RH) and horns (HIGH and LOW).
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off after 30 seconds or when BCM receives any signal from key fob.
CAN Communication System Description
AIS001VQ
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.
