Component Parts and Harness Connector LocationNKS003GZ
System DescriptionNKS003H0
Control of the parking, license plate, side marker 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, side marker and tail lamps to illumi-
nate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication lines. CPU (central processing unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs power to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp control unit is controlled, and a tail lamp (LED) is made to
turn ON.
OUT LINE
Power is supplied at all times
through 10A fuse (No. 71, located in IPDM E/R)
to tail lamp relay, located in IPDM E/R and
to CPU located in IPDM E/R,

through 15A fuse (No. 78, located in IPDM E/R)
to CPU located in IPDM E/R.
Power is also supplied at all times
through 50A fusible link (letter M, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 15A fuse [No. 22, located in fuse block (J/B)]
to BCM terminal 42,
through 10A fuse [No. 20, located in fuse block (J/B)]
to rear combination lamp control unit terminal 1,
through 10A fuse [No. 19, located in fuse block (J/B)]
to combination meter terminal 8 and
to unified meter and A/C amp. terminal 21.
With ignition switch in ON or START position, power is supplied
through ignition relay, located in IPDM E/R, from battery direct,
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38,
through 10A fuse [No. 12, located in fuse block (J/B)]
to combination meter terminal 7 and
to unified meter and A/C amp. terminal 22.
With ignition switch 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 terminals 49 and 52
through grounds M35, M45 and M85,
to IPDM E/R terminals 38 and 60
through grounds E21, E50 and E51,
to rear combination lamp control unit terminal 7

to combination meter terminals 5, 6 and 15
through grounds M35, M45 and M85,
to unified meter and A/C amp. terminals 29 and 30
through grounds M35, M45 and M85.
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, side marker and tail lamps to illuminate. This input signal is
communicated to the IPDM E/R through the CAN communication lines. The CPU located in the IPDM E/R
controls the tail lamp relay coil, which when energized, directs power.
