PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
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
to ignition relay, located in IPDM E/R, from battery direct,
through 10A fuse (No. 71, located in IPDM E/R)
to tail lamp relay, located in IPDM E/R and
