FRONT FOG LAMPPFP:26150
Component Parts and Harness Connector LocationEKS00P3Y
System DescriptionEKS00P3Z
The control of the front fog lamps is dependent upon the position of the combination switch (lighting switch).
The lighting switch must be in the 1ST position, 2ND position or AUTO position (LOW beam is ON) for front
fog lamp operation. When the lighting switch is placed in the front fog lamp position, the BCM (body control
module) receives input signal requesting the front fog lamps to illuminate. When the headlamps are illumi-
nated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication. The CPU (central processing unit) of 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
lto ignition relay (located in IPDM E/R) and
lto front fog lamp relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 10A fuse [No. 19, located in fuse block (J/B)]
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied

TURN SIGNAL AND HAZARD WARNING LAMPS
lto side turn signal lamp LH terminal 1 and
lto rear combination lamp LH terminal 2.
Ground is supplied
lto front combination lamp LH terminal 2
lto side turn signal lamp LH terminal 2 and
lto rear combination lamp LH terminal 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the left
turn signal indicator lamp.
With power and input supplied, BCM controls flashing of LH turn signal lamps.
RH Turn
When the turn signal switch is moved to the right position, BCM receives input signal requesting right turn sig-
nals to flash.
BCM then supplies power
lthrough BCM terminal 48
lto front combination lamp RH terminal 1
lto side turn signal lamp RH terminal 1 and
lto rear combination lamp RH terminal 2.
Ground is supplied
lto front combination lamp RH terminal 2
lto side turn signal lamp RH terminal 2 and
lto rear combination lamp RH terminal 3
lthrough ground E21, E41 and E61.
The BCM also supplies input to combination meter terminals 11 and 12 through the CAN communication. This
input is processed by unified meter control unit in combination meter, which in turn supplies ground to the right
turn signal indicator lamp.
With power and input supplied, BCM controls flashing of RH turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 10A fuse [No. 19, located in fuse block (J/B)]
lto combination meter terminal 3.
Ground is supplied
lto BCM terminal 55 and
lto combination meter terminal 23
lthrough grounds M21, M80 and M83.
When the hazard switch is depressed, ground is supplied
lto BCM terminal 33
lthrough hazard switch terminal 2
lthrough hazard switch terminal 1
lthrough grounds M21, M80 and M83.
When the hazard switch is depressed, BCM receives input signal requesting turn signals to flash.
BCM then supplies power

CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer toGI-50, "
