System Description

NKS001PC

●

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

●

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

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 10A 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 F, located in fuse and fusible link block)

●

to BCM terminal 55,

●

through 10A fuse [No. 18, located in fuse block (J/B)]

●

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,

FRONT FOG LAMP

Revision: 2006 August

2006 Murano

●

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

●

to BCM terminal 38.

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

●

through grounds M14 and M78,

●

to IPDM E/R terminals 38 and 60

●

through grounds E13, E26 and E28.

FRONT FOG LAMP OPERATION

When the lighting switch is in front fog lamp ON position and also in 2ND position or AUTO position (LOW
beam is ON*), BCM detects FR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by BCM
combination switch reading function. BCM sends front fog lamp request signal (ON) through CAN communica-
tion.
When receiving front fog lamp request signal (ON), IPDM E/R turns ON front fog lamp relay in IPDM E/R.
IPDM E/R supplies 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 RH and LH terminals 2

●

through grounds E13, E26 and E28.

With power and ground supplied, front fog lamp illuminate.
*: For a description of auto light operation, refer to

LT-81, "System Description"

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

NKS001PD

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.
