FRONT FOG LAMP

PFP:26150

Component Parts and Harness Connector Location

AKS00AMD

System Description

AKS005P3

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The light-
ing switch must be in the 2ND position or AUTO position (headlamp is ON) for front fog lamp operation. When
the lighting switch is placed in the fog lamp position the BCM (body control module) receives input signal
requesting the 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 communication 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

●

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

●

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

to BCM terminal 42.

When the ignition switch is in ON or START position, power is supplied

●

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

●

through 10A fuse [No. 1, located in fuse block (J/B)]

●

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

●

●

to BCM terminal 11.

Ground is supplied

●

to BCM terminal 52

●

through grounds E13, E26 and E28,

●

to IPDM E/R terminals 38 and 60

●

through grounds E13, E26 and E28.

FOG LAMP OPERATION

The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the fog
lamp relay. The 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 E13, E26 and E28,

●

to front fog lamp RH terminal 2

●

through grounds E13, E26 and E28.

With power and grounds supplied, the 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 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 fog lamps (and headlamps) remain illuminated for 5 minutes, and then the 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 Description

AKS004JX

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.
