AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM
System Diagram
INFOID:0000000005259714
System Description
INFOID:0000000005259715
The auto light control system has an optical sensor that detects outside brightness.
When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail and
headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details,
EXL-28, "HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"
.
AUTO LIGHT OPERATION
The auto light system operates the low beam and high beam headlamps, parking lamps, tail lamps and license
plate lamps. The BCM monitors the lighting switch (combination switch) position as a part of the BCM combi-
nation switch reading function. When the lighting switch is in the AUTO position, the BCM automatically turns
the lamps ON/OFF according to ambient light brightness.
NOTE:
Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-III. Refer to
"HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)"

Description
BCM
BCM (Body Control Module) controls auto light operation accord-
ing to signals from optical sensor, lighting switch, door switches,
and ignition switch.
IPDM E/R
IPDM E/R (Intelligent Power Distribution Module Engine Room)
operates parking, license plate, tail and headlamps according to
CAN communication signals from BCM.
Combination switch (lighting switch)
The lighting switch outputs lighting requests to the BCM.

FRONT FOG LAMP
System Diagram
INFOID:0000000005259718
System Description
INFOID:0000000005259719
The front fog lamps are activated with the lighting switch (combination switch). The lighting switch signal to the
BCM is monitored with the BCM combination switch reading function. When the fog lamps are turned ON with
the lighting switch, the BCM sends a front fog lamp request signal via CAN communication lines to the IPDM
E/R. The IPDM E/R grounds the front fog lamp relay coil to activate the front fog lamps.
FRONT FOG LAMP OPERATION
When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP1, 2 ON or the AUTO LIGHT ON. The
BCM sends a front fog lamp request ON signal via the CAN communication lines to the IPDM E/R. The IPDM
E/R then turns ON the front fog lamp relay sending power to the front fog lamps.

System Description
INFOID:0000000005259723
TURN SIGNAL OPERATION
When the turn signal switch is in LH or RH position with the ignition switch in ON position, the BCM detects the
TURN RH or TURN LH ON request. The BCM outputs the flasher signal to the respective turn signal lamp.
The BCM also sends a turn indicator signal ON request via the CAN communication lines to the combination
meter. The combination meter then activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazard indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combination meter then activates the hazard indicator and audible
buzzer.
REMOTE KEYLESS ENTRY OPERATION
The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard
lamps.
