System Description

AKS007LM

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) 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 headlamp high and headlamp low relay coils. These relays,
when energized, direct power to the respective headlamps, which then illuminate. 

OUTLINE

Power is supplied at all times

●

to headlamp high relay [located in IPDM E/R (intelligent power distribution module engine room)] 

●

to headlamp low relay [located in IPDM E/R (intelligent power distribution module engine room)] 

●

through 50A fusible link (letter F, located in fuse and fusible link block)

●

to BCM (body control module) terminal 7

●

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)]

●

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

●

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. 14, located in fuse block (J/B)]

●

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 

●

●

to combination meter terminal 22, 23 and 24

●

through grounds M14 and M78.

Low Beam Operation

With the lighting switch in 2ND position, the BCM receives input signal requesting the headlamps 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 headlamp low relay coil, which when energized, directs power

●

to 15A fuse [No. 83, located in IPDM E/R]

●

through IPDM E/R terminal 27

●

to headlamp RH terminal 4, and

●

to 15A fuse [No. 84, located in IPDM E/R]

●

through IPDM E/R terminal 21

●

to headlamp LH terminal 4.

Ground is supplied at all times

●

to headlamp RH terminal 5

●

through grounds E13, E26 and E28, and

●

to headlamp LH terminal 5

●

through grounds E13, E26 and E28.

With power and ground supplied, low beam headlamps illuminate.

High Beam Operation/Flash-to-Pass Operation

With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM (body control module)
receives input signal requesting the headlamp high beams 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) in the IPDM E/R controls the headlamp high relay coil, which when energized,
directs power

●

to 10A fuse [No. 86, located in IPDM E/R]

●

through IPDM E/R terminal 24

●

to headlamp RH terminal 1, and

●

to 10A fuse [No. 85, located in IPDM E/R]

●

through IPDM E/R terminal 22 

●

to headlamp LH terminal 1.

Ground is supplied

●

to headlamp RH terminal 5

●

through grounds E13, E26 and E28, and

●

to headlamp LH terminal 5

●

through grounds E13, E26 and E28.

With power and ground supplied, the high beam headlamps illuminate.
The unified meter and A/C amp that received the high beam request signal by BCM across the CAN commu-
nication makes a high beam indicator lamp turn on in combination meter.

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 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

AUTO LIGHT OPERATION

Refer to 

LT-140, "System Description"

  in “AUTO LIGHT SYSTEM”.

VEHICLE SECURITY SYSTEM

The vehicle security system will flash the high beams if the system is triggered. Refer to 

BL-142, "VEHICLE

SECURITY (THEFT WARNING) SYSTEM"

 .

CAN Communication System Description

AKS007LN

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.
