PARKING, LICENSE PLATE AND TAIL LAMPS
Component Parts and Harness Connector LocationINFOID:0000000001328382
System DescriptionINFOID:0000000001328383
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 parki ng, 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 processi ng unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs pow er to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp cont rol 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 IP DM 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
 to CPU 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 M, located in fuse, fusible link and relay box)

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 ma rker and tail lamps to illuminate. This input signal is
communicated to the IPDM E/R through the CAN communi cation. The CPU located in the IPDM E/R controls
the tail lamp relay coil, which when energized, directs power.
