Part
Description
BCM
• Detects each switch condition with the combination switch reading function.
• Judges the headlamp ON/OFF status according to the vehicle condition.
- Requests the front fog lamp relay ON to IPDM E/R (with CAN communication).
IPDM E/R
Controls the integrated relay and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch
(Lighting & turn signal switch)
ECM
Transmits the engine condition signal to BCM with CAN communication.
Combination meter
Transmits the parking brake switch signal to BCM with CAN communication.

AUTO LIGHT SYSTEM
System Diagram
INFOID:0000000009722997
System Description
INFOID:0000000009722998
OUTLINE
• Auto light system is controlled by each function of BCM and IPDM E/R.
Control by BCM
- Combination switch reading function
- Headlamp control function
- Auto light function
- Delay timer function
Control by IPDM E/R
- Relay control function
• Auto light system has the auto light function and the delay timer function.
- Auto light function turns the exterior lamps* and each illumination ON/OFF automatically according to the
outside brightness.
- When auto light system turns the exterior lamps ON with the ignition switch OFF, delay timer function turns
the exterior lamps OFF depending on the vehicle condition with the auto light function after a certain period
of time.
*: Headlamp (LO/HI), parking lamp, tail lamp, side marker lamp and front fog lamp (Headlamp HI and front fog
lamp depend on the combination switch condition.)
AUTO LIGHT FUNCTION
• BCM detects the combination switch condition with the combination switch reading function.
• BCM supplies voltage to optical sensor when the ignition switch is turned ON or ACC.
• Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
• BCM judges outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior
lamp and each illumination according to the outside brightness.
• BCM transmits each request signal to IPDM E/R with CAN communication according to ON/OFF condition
by the auto light function.
NOTE:
ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT. Refer to
EXL-212, "HEADLAMP : CONSULT Function (BCM - HEAD LAMP)"
.
DELAY TIMER FUNCTION
BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
• Turns the exterior lamp OFF 5 minutes after detecting that any door opens (Door switch ON).
• Turns the exterior lamp OFF a certain period of time* after closing all doors (Door switch ON
→
OFF).

AUTO LIGHT SYSTEM
• Turns the exterior lamp OFF with the ignition switch ACC or the light switch OFF.
*: The preset time is 45 seconds. The timer operating time can be set by CONSULT. Refer to
"HEADLAMP : CONSULT Function (BCM - HEAD LAMP)"
NOTE:
When any position other than the light switch AUTO is set, the auto light system function switches to the exte-
rior lamp battery saver function.

• Detects each switch condition by the combination switch reading function.
• Judges the outside brightness from the optical sensor signal.
• Judges the OFF timing according to the vehicle condition.
• Judges the ON/OFF status of the exterior lamp and each illumination according to the
outside brightness and the vehicle condition.
- Requests ON/OFF of each relay to IPDM E/R (with CAN communication).
IPDM E/R
Controls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).

FRONT FOG LAMP SYSTEM
System Diagram
INFOID:0000000009723001
System Description
INFOID:0000000009723002
OUTLINE
Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and relay control function of IPDM E/R.
FRONT FOG LAMP OPERATION
• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog light request signal to IPDM E/R with CAN communication according to the front
fog lamp ON condition.
Front fog lamp ON condition
- Front fog lamp switch ON with headlamp ON (except for the high beam ON)
• IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the
front fog light request signal.
