HEADLAMP SYSTEM

System Diagram

INFOID:0000000003773647

System Description

INFOID:0000000003773648

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 function ON judgment)
• 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-8, "System Diagram"

.

Combination meter
(High beam indicator lamp)

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