PARKING, LICENSE PLATE AND TAIL LAMPS

Revision; 2004 April

PARKING, LICENSE PLATE AND TAIL LAMPS

PFP:26550

System Description

AKS004LB

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 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

●

through 10A fuse [No. 75, 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)]

●

through 15A fuse [No. 73, 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 F, located in fuse and fusible link block)

●

to BCM (body control module) terminal 7.

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

●

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

●

to BCM (body control module) terminal 35

●

through 10A fuse [No. 80, 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)]

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 (body control module) terminal 36.

Ground is supplied

●

to BCM (body control module) terminal 8

●

through grounds E13, E26 and E28

●

to IPDM E/R (intelligent power distribution module engine room) terminals 14 and 45

●

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 37

●

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

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

COMBINATION SWITCH READING FUNCTION

Refer to

LT-251, "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,
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
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.
