HEADLAMP SYSTEM : System Description
INFOID:0000000011413319
SYSTEM DIAGRAM
OUTLINE
Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
Smart FET control function of IPDM E/R.
HEADLAMP (LO) OPERATION
• BCM detects the combination switch condition with the combination switch reading function.
• BCM transmits the low beam request signal to IPDM E/R with CAN communication according to the head-
lamp (LO) ON condition.
Headlamp (LO) ON condition:
- Lighting switch 2ND
- Lighting switch AUTO (auto light function ON judgment)
- Lighting switch AUTO, with the front fog lamp switch ON and the ignition switch ON
- Lighting switch PASS
HEADLAMP (HI) OPERATION
• BCM transmits the high beam request signal to IPDM E/R and the combination meter with CAN communica-
tion according to the headlamp (HI) ON condition.
Headlamp (HI) ON condition:
- Lighting switch HI with the lighting switch 2ND or AUTO (auto light function ON judgment)
- Lighting switch PASS
- Lighting switch AUTO, with the front fog lamp switch ON, the ignition switch ON and lighting switch HI
• Combination meter turns the high beam indicator lamp ON according to the high beam request signal.
• IPDM E/R turns the headlamp ON according to the high beam request signal.
HEADLAMP SYSTEM : Fail-Safe
INFOID:0000000011413320
CAN COMMUNICATION CONTROL
When CAN communication with BCM is impossible, IPDM E/R performs fail-safe control. After CAN communi-
cation recovers normally, it also returns to normal control.
If no CAN communication is available with BCM

AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM : System Description
INFOID:0000000011413321
SYSTEM DIAGRAM
OUTLINE
• Auto light system is controlled by each function of BCM and IPDM E/R.
Controlled by BCM:
- Combination switch reading function
- Headlamp control function
- Auto light function
- Delay timer function
- Auto light adjustment system
Controlled by IPDM E/R:
- Auto light system has the auto light function and delay timer function.
- Auto light function automatically turns ON/OFF the exterior lamps* and each illumination automatically,
depending on 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, side marker lamp, tail 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 and combination meter via 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
BCS-19, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"
AUTO LIGHT ADJUSTMENT SYSTEM
Control part
Fail-safe operation
Headlamp
• Turns ON the headlamp low beam when the ignition switch is turned ON
• Turns OFF the headlamp low beam when the ignition switch is turned OFF

SYSTEM
The auto light adjustment system automatically dims/brightens the display according to brightness outside the
vehicle when lighting switch 1ST, lighting switch 2ND or lighting switch AUTO is operated. Refer to
"AUTO LIGHT SYSTEM : System Description"
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).
• 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
LAMP : CONSULT Function (BCM - HEADLAMP)"
(with Intelligent Key system) or
CONSULT Function (BCM - HEADLAMP)"
(without Intelligent Key system).
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.
DAYTIME RUNNING LIGHT SYSTEM
DAYTIME RUNNING LIGHT SYSTEM : System Description
INFOID:0000000011413322
SYSTEM DIAGRAM
OUTLINE
• Daytime running light is controlled by daytime running light control function and combination switch reading
function of BCM, and smart FET of IPDM E/R.
DAYTIME RUNNING LIGHT OPERATION
• BCM detects the combination switch condition by the combination switch reading function.
• BCM detects the vehicle condition according to ignition switch
• BCM detects the parking brake condition by the parking brake switch signal received from combination
meter using CAN communication.
• BCM transmits the daytime running light request signal to IPDM E/R using CAN communication according to
the daytime running light ON condition.
Daytime running light ON condition:
- Vehicle condition READY
- Lighting switch OFF or 1ST
- Lighting switch AUTO, and the auto light function OFF judgment
- Parking brake switch OFF
• IPDM E/R controls the daytime running light request signal.
• Power is supplied from the IPDM E/R to the daytime lights.
