tion".
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
DELAY TIMER FUNCTION
Delay timer function carries out a function that BCM ac tivates the timer and controls lights out of headlamps by
door switch signal and lightning switch signal when turn ing the Ignition switch OFF while it is ON and head-
lamps are ON by the auto light function.
Timer types are a 5 minute timer and a 45 second timer
When opening any door (door switch is ON), the 5 mi nute timer starts and then headlamps go out 5 minutes
later
When all the doors are closed (from door switch ON to OFF), the 45 second timer starts and then headlamps go out 45 seconds later. If any door is opened (door switch ON) while the 45 second timer is in operation, the
5 minute timer starts again
The timer stops when turning on the ignition switch or turning off the auto light switch under the above condi-
tions.
Delay timer control mode can be changed by the f unction setting of CONSULT-III or display.
CAN Communication System DescriptionINFOID:0000000001328308
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 s peed 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 CA N 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 UnitINFOID:0000000001328309
Refer to LAN-43, "CAN System Specification Chart".
Major Component and FunctionsINFOID:0000000001328310
Components Functions
BCM Turns on/off circuits of tail light and headlamp according to signals from light sensor, lighting switch (AUTO),
driver door switch, passenger door switch, rear door switch, and ignition switch (ON, OFF).
Optical sensor Converts outside brightness (lux) to voltage, and sends it to BCM. (Detects brightness of 800 to 2,500 lux)
