AKS00ALQ

System Description

AKS004LB

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 parking, 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)
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 parking, license plate, side marker and tail
lamps, which then illuminate. 
Power is supplied at all times

to ignition relay, loctated 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.

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

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

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

to BCM terminal 38.

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 52

through grounds E13, E26 and E28,

to IPDM E/R terminals 38 and 60

through grounds E13, E26 and E28.

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

through IPDM E/R terminal 22

to front combination lamp RH terminal 7

to front combination lamp LH terminal 7

to rear combination lamp RH terminal 1

to rear combination lamp LH terminal 1

to license plate lamp RH terminal 1

to license plate lamp LH terminal 1.

Ground is supplied at all times

to front combination lamp RH terminal 5

through grounds E13, E26 and E28,

to front combination lamp LH terminal 5

through grounds E13, E26 and E28,

to rear combination lamp RH terminal 4

through grounds B7 and B20,

to rear combination lamp LH terminal 4

through grounds B7 and B20,

to license plate lamp RH terminal 2

through grounds B7 and B20,

to license plate lamp LH terminal 2

through grounds B7 and B20.

With power and ground supplied, the parking, license plate, side marker and tail lamps illuminate.

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 plate, side marker and tail lamps remain illuminated for 5 minutes,
and 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 Description

AKS004LC

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
