System DescriptionNKS003TH
Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated)
the BCM (body control module) receives input signal requesting the illumination 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) located in the IPDM E/R controls the tail lamp relay
coil. This relay, when energized, directs power to the illumination lamps, which then illuminate.

ILLUMINATION 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 illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil,
which, when energized, directs power

through IPDM E/R terminal 21

to combination meter terminal 13

to LDW switch (illumination) terminal 5 (with lane departure warning)

to VDC off switch (illumination) terminal 3

to trunk lid opener switch (illumination) terminal 3

to combination switch (spiral cable) terminal 24

to door mirror remote control switch (illumination) terminal 16

to AFS switch (illumination) terminal 5 (with AFS)

to rear sunshade front switch (illumination) terminal 5 (with rear control switch)

to A/T illumination terminal 1

to rear control cancel switch (illumination) terminal 4 (with rear control switch)

to clock terminal 3

to multifunction switch terminal 3

to audio unit terminal 9

to DVD player terminal 18 (with DVD player)

to NAVI control unit terminal 61 (with navigation system)

to AV control unit terminal 61 (without navigation system)

EXTERIOR LAMP BATTERY SAVER CONTROL
BCM activates the exterior lamp battery saver control function and turns off the exterior lamps to prevent bat-
tery from over discharge when the combination switch (lighting switch) is in 1ST or 2ND position and/or the
front fog lamp switch ON and the door lock operation is performed by keyless entry system.
CAN Communication System DescriptionNKS003TI
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 UnitNKS003TJ
Refer to LAN-50, "CAN System Specification Chart" .
