OUTLINE

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

Control by BCM

• Combination switch reading function
• Headlamp control function

Control by IPDM E/R

• Relay control function

Control by combination meter

• Meter illumination control function (Refer to 

MWI-24, "METER ILLUMINATION CONTROL : System Descrip-

tion"

.)

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
• 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 enters in the nighttime mode according to position light request signal. Under the night-

time mode the combination meter controls the illuminance by controlling the each illumination lamp (ground
side).

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

• Enters in nighttime mode according to the request from BCM (with CAN communi-

cation).

• Controls the each illumination in the nighttime mode.
