The headlamps will then illuminate. For a description of headlamp operation, Refer to LT- 5 , "System Descrip-
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.

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)

FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination s witch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, t he CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power
 through IPDM E/R terminal 36
