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.
OUTLINE
Power is supplied at all times

through 15A fuse (No. 88, located in IPDM E/R)

to front fog lamp relay, located in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)

to ignition relay, located in IPDM E/R, from battery direct,

through 10A fuse (No. 71, located in IPDM E/R)

When ignition switch is in ACC or ON position, power is supplied

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

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.
