System Diagram
Components Description
NOTE:
*: This indicates in a few seconds for the system check during ignition switch ON.
POWER SUPPLY AND GROUND CIRCUIT
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 12, located in the fuse block (J/B)]

to LDW camera unit terminal 1.
Ground is supplied

to LDW camera unit terminals 6 and 12

CAN CommunicationAKS00C6X
SYSTEM DESCRIPTION
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 two
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.

High Beam Operation/Flash-to-Pass Operation
With the lighting switch in the 2ND position and placed in the 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
and low relay coil, which when energized, directs power

through 15A fuse (No. 76, located in IPDM E/R)

FRONT FOG LAMP OPERATION
The front fog lamp switch is built into combination switch. The lighting switch must be in the 2ND position or
AUTO position (headlamp is ON) and the front fog lamp switch must be ON for front fog lamp operation.
With the front fog lamp switch in the ON position, the CPU located in the IPDM E/R grounds the coil side of the
front fog lamp relay. The front fog lamp relay then directs power

through IPDM E/R terminal 37

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the front fog lamp switch is ON, and
the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the front fog lamps (and headlamps) remain illuminated for 5 minutes, then the front fog
lamps (and headlamps) are turned off.
