PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationAKS007O7
System DescriptionAKS007DT
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, side marker and tail lamps to illuminate.
This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across
the CAN communication lines. The CPU (central processing unit) of the IPDM E/R (intelligent power distribu-
tion module engine room) 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 unit is controlled, and a tail lamp (LED) is made to turn on.
Power is supplied at all times

through 10A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)]

to tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)] and

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine
room)].

through 15A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine
room)].
Power is also supplied at all times

through 50A fusible link (letter M, located in the fuse and fusible link block)

to BCM (body control module) terminal 55

through 15A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) terminal 42

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 across the CAN communication lines. The CPU in the IPDM E/R controls the
tail lamp relay coil, which when energized, directs power
