FRONT FOG LAMP
Revision: 2005 July 2005 FX

to BCM terminal 38.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51.
FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. 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, the 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 37

to front fog lamp LH terminal 1,

through IPDM E/R terminal 36

to front fog lamp RH terminal 1.
Ground is supplied

to front fog lamp LH terminal 2

through grounds E21, E50 and E51,

to front fog lamp RH terminal 2

through grounds E21, E50 and E51.
With power and grounds supplied, front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionAKS007CJ
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 UnitAKS0080V
Refer to LAN-30, "CAN Communication Unit" .

through rear combination lamp RH terminal 4

to rear combination lamp control unit terminal 8.
BCM sends signal to the unified meter and A/C amp. through the CAN communication lines, and turns ON turn
signal indicator lamp with combination meter.
With power and input supplied, BCM controls the flashing of hazard warning lamps when key fob is used to
activate remote control entry system.
