FRONT FOG LAMP

FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationBKS001OP
System DescriptionBKS001OQ

BCM (Body Control Module) controls front fog lamp operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates front fog lamp according to CAN
communication signals from BCM.

Unified meter and A/C amp. operates front fog lamp indicator according to CAN communication signals.
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 front fog lamp relay (located in IPDM E/R),

through 15A fuse (No. 71, located in IPDM E/R)

to CPU (central processing unit) located in IPDM E/R,

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

to CPU located in IPDM E/R,

through 50A fusible link (letter M, located in fuse and fusible link block)

to BCM terminal 55,

through 15A fuse [No. 17, located in fuse block (J/B)]

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

to ignition relay (located in IPDM E/R),

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

to BCM terminal 38,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 8.
When the 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 terminal 52 and

to combination meter terminals 10, 11 and 12

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), BCM detects FR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by
BCM combination switch reading function. And then, BCM sends front fog lamp request signal (ON) through
CAN communication.
When receiving front fog lamp request signal (ON), IPDM E/R turns ON front fog lamp relay in IPDM E/R. And
then, front fog lamp go ON. IPDM E/R supplies power

through IPDM E/R terminal 36

to front fog lamp RH terminal 1,

through IPDM E/R terminal 37

to front fog lamp LH terminal 1.
Ground is supplied

to front fog lamp RH and LH terminals 2

through grounds E1 and E31.
With power and ground supplied, the front fog lamp illuminates.
Unified meter and A/C amp. receives front fog lamp request signal (ON) through CAN communication, and
make front fog indicator go ON in combination meter.

CAN Communication System DescriptionBKS001OR
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 UnitBKS001OS
Refer to LAN-49, "CAN System Specification Chart" .
