System Diagram

INFOID:0000000003534165

System Description

INFOID:0000000003534166

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
• 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 (through the unified

meter and A/C amp.) with CAN communication according to the headlamp (HI) ON condition. 

Headlamp (HI) ON condition

- Lighting switch HI with the lighting switch 2ND
- 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.
