HEADLAMP SYSTEM

System Diagram

INFOID:0000000009945098

System Description

INFOID:0000000009945099

OUTLINE

Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
relay 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, and the auto light function ON judgment (With auto light system)
• IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low

beam request signal.

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
• Combination meter turns the high beam indicator lamp ON according to the high beam request signal. 
• IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp ON according to the high

beam request signal.

Part

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges that the headlamp is turned ON according to the vehicle condition. 
- Requests the headlamp relay (HI/LO) ON to IPDM E/R (with CAN communication). 
- Requests the high beam indicator lamp ON to the combination meter (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)

Refer to 

BCS-11, "System Diagram"

 (with Intelligent Key) or 

BCS-96, "System Dia-

gram"

 (without Intelligent Key).

Combination meter
(High beam indicator lamp)

Turns the high beam indicator lamp ON according to the request from BCM (with CAN 
communication).

AUTO LIGHT SYSTEM

System Diagram

INFOID:0000000009945106

System Description

INFOID:0000000009945107

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
- Wiper linked auto lighting function

Control by IPDM E/R

- Relay control function
• Auto light system has the auto light function (with twilight lighting function), wiper linked auto lighting function

and delay timer function.

- Auto light function automatically turns ON/OFF the exterior lamps* and each illumination automatically,

depending on the outside brightness.

- Wiper linked auto lighting function automatically turns ON/OFF the exterior lamps* and each illumination

when the light switch is in the AUTO position, according to a front wiper operation.

- 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 (illuminated as front side marker lamps too), tail lamp, rear side marker
lamp and front fog lamp (Headlamp HI and front fog lamp depend on the combination switch condition.)
NOTE:
The settings of the twilight lighting function and the wiper linked auto lighting function can be changed with
CONSULT. Refer to 

EXL-21, "HEADLAMP : CONSULT Function (BCM - HEAD LAMP)"

.

AUTO LIGHT FUNCTION (WITH TWILIGHT LIGHTING FUNCTION)

Description

• BCM detects the combination switch condition with the combination switch reading function.
• BCM supplies voltage to the 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 detects outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior

lamp and each illumination, depending on the outside brightness condition (standard or twilight). 

• BCM transmits each request signal to IPDM E/R via CAN communication, according to ON/OFF condition by

the auto light function.
