TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: June 20062007 Versa
Ground is supplied
to front combination lamp LH terminal 5
through grounds E15 and E24,
to rear combination lamp LH terminal 1
through grounds B7 and B19.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power
through BCM terminal 61
to front combination lamp RH terminal 4 and
to rear combination lamp RH terminal 6.
Ground is supplied
to front combination lamp RH terminal 5
through grounds E15 and E24,
to rear combination lamp RH terminal 1
through grounds B117, B132 and B402.
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
HAZARD LAMP OPERATION
Power is supplied at all times
through 40A fusible link (letter g , located in fuse, fusible link and relay box)
to BCM terminal 70,
through 10A fuse [No. 8, located in fuse block (J/B)]
to BCM terminal 57,
through 10A fuse [No. 13, located in fuse block (J/B)]
to combination meter terminal 27.
Ground is supplied
to hazard switch terminal 1,
to BCM terminal 67, and
to combination meter terminals 21, 22 and 23
through grounds M57 and M61.
When hazard switch is depressed, ground is supplied
through hazard switch terminal 2
to BCM terminal 29.
BCM then supplies power
to front combination lamp LH terminal 4 and
to rear combination lamp LH terminal 6
through BCM terminal 60,
to front combination lamp RH terminal 4 and
to rear combination lamp RH terminal 6
through BCM terminal 61.
Ground is supplied
to front combination lamp LH and RH terminal 5
through grounds E15 and E24,

through grounds B117, B132 and D402.
The BCM also supplies input to combination meter across the CAN communication lines. This input is pro-
cessed by unified meter control unit in combination meter, which in turn supplies ground to the left and right
turn signal indicator lamps.
With power and input supplied, BCM controls flashing of hazard warning lamps.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times
through 40A fusible link (letter g , located in fuse, fusible link and relay box)
to BCM terminal 70,
through 10A fuse [No. 13, located in fuse block (J/B)]
to combination meter terminal 27.
Ground is supplied
to BCM terminal 67 and
to combination meter terminals 21, 22 and 23
through grounds M57 and M61.
When the remote keyless entry system is triggered by input from the keyfob, the BCM supplies power
through BCM terminal 60
to front combination lamp LH terminal 4 and
to rear combination lamp LH terminal 6,
through BCM terminal 61
to front turn signal lamp RH terminal 4 and
to rear combination lamp RH terminal 6.
Ground is supplied
to front combination lamp LH and RH terminals 5
through grounds E15 and E24,
to rear combination lamp LH terminal 1
through grounds B7 and B19,
to rear combination lamp RH terminal 1
through grounds B117, B132 and D402.
The BCM also supplies input to combination meter via the CAN communication lines. This input is processed
by the unified meter control unit in combination meter, which in turn supplies ground to the left and right turn
signal indicator lamps.
With power and ground supplied, BCM controls flashing of hazard warning lamps when keyfob is used to acti-
vate remote keyless entry system.

System DescriptionEKS00HYZ
The control of the parking, license plate and tail lamp operation is dependent upon the position of lighting
switch. When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input
signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized,
directs power to parking, license plate and tail lamps, which then illuminate.
Power is supplied at all times
to ignition relay located in IPDM E/R,
to tail lamp relay located in IPDM E/R,
through 15A fuse (No. 52, located in IPDM E/R) and
through 20A fuse (No. 53, located in IPDM E/R)
to the CPU located in the IPDM E/R,
through 40A fusible link (letter g , located in fuse and fusible link block)
to BCM terminal 70,
through 10A fuse [No. 8, located in fuse block (J/B)],
to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 38,
to ignition relay located in IPDM E/R and
through the ignition relay
to the CPU of the IPDM E/R.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 20, located in fuse block (J/B)]
to BCM terminal 11.
Ground is supplied
to BCM terminal 67
through grounds M20 and M61,
to IPDM E/R terminals 59 and 39
through grounds E15 and E24.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives an input signal requesting parking,
license plate and tail lamps to illuminate. This input signal is communicated to the IPDM E/R via the CAN com-
munication lines. The CPU, located in the IPDM E/R, controls the tail lamp relay coil. When energized, the tail

to room lamp terminal 3.
INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System
When room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 seconds) for room lamp ON/OFF.
In addition, when the interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 sec-
ond.
Power is supplied
through 10A fuse [No. 14, located in fuse block (J/B)]
to key switch and key lock solenoid terminal 2.
When the key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM termi-
nal 37.
When front door key cylinder switch LH is unlocked, ground is supplied
to BCM terminal 7
through front door key cylinder switch LH terminal 3
through front door key cylinder switch LH terminal 2
through grounds M57 and M61.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp timer operation condition is met, and turns the room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON),
Power is supplied
through key switch and key lock solenoid terminal 1
to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), the power supply to BCM ter-
minal 37 is terminated. BCM detects that key has been removed, determines that interior room lamp timer
conditions are met, and turns the room lamp ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), voltage at BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM
determines that conditions for room lamp operation are met and turns the room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:
Front door LH is locked (locked front door key cylinder switch LH).
Front door LH is opened (front door switch LH).
Ignition switch ON.
With Intelligent Key System
When the room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 second) for room lamp ON/OFF.
In addition, when interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
through 10A fuse (No. 31, located in fuse and fusible link box)
to key switch and ignition knob switch terminals 2 and 4.
