DAYTIME RUNNING LIGHT SYSTEM

System Diagram

INFOID:0000000001099320

System Description

INFOID:0000000001099321

OUTLINE

• Turns the following exterior lamps ON as the daytime running light.
- headlamp (LO)
- Tail lamp, parking lamp and license plate lamp
• Daytime running light is controlled by daytime running light control function and combination switch reading

function of BCM, and relay control function of IPDM E/R.

DAYTIME RUNNING LIGHT OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.
• BCM detects the engine condition by the engine status signal received from ECM with CAN communication.
• BCM transmits the daytime running light request signal and low beam request signal to IPDM E/R with CAN

communication according to the daytime running light ON condition.

Daytime running light ON condition

- Engine running
- Lighting switch OFF or AUTO
• IPDM E/R turns the integrated headlamp low relay and tail lamp relay ON according to the daytime running

light request signal and low beam request signal. And it turns each lamps ON.

Description

BCM

• Detects each switch condition with the combination switch reading function.
• Judges each lamps ON/OFF condition according to the vehicle condition. Requests 

the each 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).

AUTO LIGHT SYSTEM

System Diagram

INFOID:0000000001099324

System Description

INFOID:0000000001099325

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

Control by IPDM E/R

- Relay control function
• Auto light function turns the exterior lamps* ON/OFF automatically according to the outside brightness.

*: Headlamp (LO/HI), parking lamp, tail lamp (Headlamp HI depends on the combination switch condition.)

AUTO LIGHT FUNCTION

• BCM detects the combination switch condition with the combination switch reading function.
• BCM detects the engine condition by the engine status signal received from ECM with CAN communication.
• BCM receives the light sensor signal [outside brightness (lux) and the light & rain sensor condition] from light

& rain sensor with the light & rain sensor serial link.

• BCM judges ON/OFF condition of the exterior lamps according to the outside brightness and the vehicle

condition. 

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

by the auto light function.

• Judges the ON/OFF status of the exterior lamp 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
