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
through 10A fuse [No. 20, located in fuse block (J/B)]
to rear combination lamp control unit terminal 1.
With the ignition switch in the ON or START position, power is supplied

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

COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST (or 2ND) position, and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the parking, license, 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 DescriptionAKS007DU
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 UnitAKS0080X
Refer to LAN-6, "CAN Communication Unit" .
