ILLUMINATION

PFP:27545

System Description

AKS004MG

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. 
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

●

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 F, located in fuse and fusible link block)

●

to BCM terminal 55,

●

through 10A fuse [No. 18, located in fuse block (J/B)]

●

to BCM terminal 42,

●

through 10A fuse [No. 21, located in fuse block (J/B)]

●

to combination meter terminal 21.

With the ignition switch in the ON or START position, power is supplied

●

to ignition relay, located in IPDM E/R, from battery direct,

●

through 10A fuse [No. 1, located in fuse block (J/B)]

●

to BCM terminal 38,

●

through 10A fuse [No. 14, located in fuse block (J/B)]

●

to combination meter terminal 20.

With the ignition switch in the ACC or ON position, power is supplied

●

through 10A fuse [No. 6, located in fuse block (J/B)]

●

to BCM terminal 11.

Ground is supplied

●

to BCM terminal and 52

●

through grounds E13, E26 and E28,

●

to IPDM E/R terminals 38 and 60 

●

through grounds E13, E26 and E28,

●

to combination meter 22, 23 and 24

●

through grounds M14 and M78.

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 22

●

to CVT illumination terminal 1

●

to VDC off switch (illumination) terminal 3 (with VDC)

●

to headlamp aiming switch (illumination) terminal 3 (with headlamp aiming)

●

to AWD lock switch (illumination) terminal 4 (AWD models)

●

to heated seat switch (driver side) (illumination) terminal 5 (with heater seat) 

●

to heated seat switch (passenger side) (illumination) terminal 5 (with heater seat)

EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, and then the illumination lamps
are turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, and illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

CAN Communication System Description

AKS004MH

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.
