HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in the 2ND position, the BCM receives input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU
located in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6.
Ground is supplied

to front combination lamp RH terminal 7

through grounds E21, E50 and E51,

to front combination lamp LH terminal 7

through grounds E21, E50 and E51.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the HIGH or PASS position, the BCM receives input
signal requesting the headlamp high beams to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay coil
and low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

through IPDM E/R terminal 20

to front combination lamp RH terminal 6,

through 15A fuse (No. 86, located in IPDM E/R)

through IPDM E/R terminal 30

to front combination lamp LH terminal 6,

through 10A fuse (No. 72, located in IPDM E/R)

through IPDM E/R terminal 27

to front combination lamp RH terminal 5,

DAYTIME LIGHT SYSTEMPFP:284B2
Component Parts and Harness Connector LocationAKS007MZ
System DescriptionAKS007N0
Daytime light system turns ON daytime light lamps while driving. Daytime light lamps are not turned ON if
engine is activated with parking brake ON. Take off parking brake to turn ON daytime light lamps. The lamps
turn OFF when the lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when the
lighting switch is in the PASSING position (daytime light lamps are not turned OFF only by parking brake
itself).
The parking brake signal and engine run/stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.

CAN Communication System DescriptionAKS007N1
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.

FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationAKS007O5
System DescriptionAKS007CI
Control of the front fog lamps is dependent upon the position of the combination switch (lighting switch). The
lighting switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp opera-
tion.When the lighting switch is placed in the fog lamp position the BCM (body control module) receives input
signal requesting the front fog lamps to illuminate. When the headlamps are illuminated, this input signal is
communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communi-
cation lines. The CPU (central processing unit) located in the IPDM E/R controls the front fog lamp relay coil.
When activated, this relay directs power to the front fog lamps.

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.
