System Diagram

INFOID:0000000003774547

System Description

INFOID:0000000003774548

OUTLINE

Each illumination lamp is controlled by each function of BCM and IPDM E/R.

Control by BCM

• Combination switch reading function
• Headlamp control function

Control by IPDM E/R

• Relay control function

ILLUMINATION CONTROL

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits position light request signal to IPDM E/R and combination meter according to tail lamp ON

condition.

Tail lamp ON condition

- Lighting switch 1ST
- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment (With auto light system)
• IPDM E/R turns the integrated tail lamp relay ON according to position light request signal. It provides the

power supply to each illumination lamp. 

• Combination meter dims the meter illumination according to position light request signal.

Description

BCM

• Detects each switch condition by the combination switch reading function.
• Judges the illumination lamp ON/OFF status depending on the vehicle condition. 

And then it transmits position light request signal to IPDM E/R and combination 
meter (with CAN communication). 

IPDM E/R

Controls the integrated relay according to the request from BCM (with CAN communi-
cation).

Combination meter

Illuminates the meter illumination according to the request signal from BCM (with CAN 
communication).

Combination switch
(Lighting & turn signal switch)
