AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM
System Diagram
INFOID:0000000007355112
System Description
INFOID:0000000007355113
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,
BCS-21, "HEADLAMP : CONSULT 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 combination switch (lighting and turn signal switch) position as a part of
the BCM combination switch reading function. When the lighting switch is in the AUTO position, the BCM auto-
matically turns the lamps ON/OFF according to ambient light brightness.
NOTE:
Timing for when lamps turn ON/OFF can be changed by the CONSULT. Refer to
CONSULT Function (BCM - HEAD LAMP)"

FRONT FOG LAMP
System Diagram
INFOID:0000000007355116
System Description
INFOID:0000000007355117
The front fog lamps are activated with the combination switch (lighting and turn signal 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

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.

System Description
INFOID:0000000007355125
PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION
When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH 1ST POSITION ON. The
BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The IPDM E/R then
activates the tail lamp relay which sends power to the parking and instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2ND position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes (early production) or 45 seconds (late
production) unless the lighting switch position is changed. If the lighting switch position is changed, then the
headlamps are turned off.
This setting can be changed by CONSULT. Refer to
