PARKING, LICENSE PLATE AND TAIL LAMPS
Revision: 2007 April2007 M35/M45
PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationNKS003SH
System DescriptionNKS003SI
The control of the parking, license plate and tail lamp operation is dependent upon the position of the lighting
switch (combination 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 sig-
nal 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 tail lamp relay
coil. This relay, when energized, directs power to parking, license plate and tail lamps, which then illuminate.
OUTLINE
Power is supplied at all times

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

to CPU located in IPDM E/R, and

to tail lamp relay 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, fusible link and relay block)

to BCM terminal 55,

through 10A fuse [No. 21, located in fuse block (J/B)]

to BCM terminal 42,

through 10A fuse [No. 22, located in fuse block (J/B)]

to key slot terminal 1.

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

to CPU located in IPDM E/R,

through 15A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38.
With the ignition switch in the 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 M16 and M70,

to IPDM E/R terminals 38 and 51

through grounds E22 and E43.
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communi-
cated to the IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls the
tail lamp relay coil, which when energized, directs power

through IPDM E/R terminal 21

to front combination lamp LH and RH terminals 5 (parking)

to front combination lamp LH and RH terminals 7 (side marker)

to rear combination lamp LH and RH terminals 1 (tail and side marker)

to license plate lamp LH and RH terminals 1.
Ground is supplied at all times

to front combination lamp LH and RH terminals 1 (parking and side marker)

through grounds E22 and E43,

to rear combination lamp LH and RH terminals 4 (tail and side marker)

through grounds B5, B40 and B131.

to license plate lamp LH and RH terminals 2

through grounds B402 and B405.
With power and ground supplied, the parking, license plate and tail lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer toBCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST (or 2ND) position, and ignition switch is turned
from ON or ACC to OFF, battery saver control feature is activated.
Under this condition, parking, license plate, side marker and tail lamps remain illuminated for 5 minutes, then
the parking, license plate, side marker and tail lamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003SJ
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 UnitNKS003SK
Refer to LAN-50, "CAN System Specification Chart" .
