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) located in 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 ignition relay, located in IPDM E/R,
●

HEADLAMP OPERATION
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 located in
the IPDM E/R controls the headlamp low relay coil, which when energized, directs power
●
through 15A fuse (No. 76, located in IPDM E/R)
●
through IPDM E/R terminal 20
●
to front combination lamp RH terminal 4,
●
through 15A fuse (No. 86, located in IPDM E/R)
●
through IPDM E/R terminal 30
●
to front combination lamp LH terminal 4.
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.
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 receives input signal
requesting the headlamp high beams 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 headlamp high relay coil, which
when energized, directs power
●
through 10A fuse (No. 72, located in IPDM E/R)
●
through IPDM E/R terminal 27
●
to front combination lamp RH terminal 1,
●
through 10A fuse (No. 74, located in IPDM E/R)
●
through IPDM E/R terminal 28
●
to front combination lamp LH terminal 1.
Ground is supplied
●
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.
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
BCS-3, "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, and 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
in “AUTO LIGHT SYSTEM”.
VEHICLE SECURITY SYSTEM
The vehicle security system will flash the high beams if the system is triggered. Refer to
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.
