Part name
Description
BCM
BCM (Body Control Module) controls auto light operation accord-
ing to signals from optical sensor, lighting switch and ignition
switch.
IPDM E/R
IPDM E/R (Intelligent Power Distribution Module Engine Room)
operates parking, license plate, tail and headlamps according to
CAN communication signals from BCM.
Combination switch (lighting and turn signal switch)
The lighting switch outputs lighting requests to the BCM.
Optical sensor
Optical sensor detects ambient brightness and converts light
(lux) to voltage, then sends the optical sensor signal to BCM.
Door switches
Detects door open/closed status and forwards that status to the
BCM.

FRONT FOG LAMP

INFOID:0000000009478437
System Description
INFOID:0000000009478438
The front fog lamps are activated with the combination switch (lighting and turn signal switch). The combina-
tion switch (lighting and turn signal switch) signal to the BCM is monitored with the BCM combination switch
reading function. When the fog lamps are turned ON with the combination switch (lighting and turn signal
switch), the BCM sends a front fog lamp request signal via CAN communication lines to the IPDM E/R. The
IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.
FRONT FOG LAMP OPERATION
When the combination switch (lighting and turn signal switch) is in front fog lamp ON position and also in 1ST
or 2ND position or AUTO (if equipped) position (headlamp is ON), the BCM detects FR FOG ON and the
HEAD LAMP1 or 2 ON. The BCM sends a front fog lamp request ON signal via the CAN communication lines
to the IPDM E/R. The IPDM E/R then turns ON the front fog lamp relay sending power to the front fog lamps.

TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal switch) is in LH or RH position with the ignition switch in
ON position, the BCM detects the TURN RH or TURN LH ON request. The BCM outputs the flasher signal to
the respective turn signal lamp. The BCM also sends a turn indicator signal ON request via the CAN commu-
nication lines to the combination meter. The combination meter then activates the appropriate turn signal indi-
cator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazard indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combination meter then activates the hazard indicator and audible
buzzer.
