Part

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 via CAN communication (through the unified meter and A/C amp.). 

IPDM E/R

Controls the integrated relay according to the request from BCM via CAN communica-
tion.

Combination meter

• Enters in the nighttime mode according to the request from BCM via CAN commu-

nication.

• Controls each illumination brightness in the nighttime mode.

Refer to 

MWI-27, "METER ILLUMINATION CONTROL : System Diagram"

.

Total illumination control unit

• Turns each illumination (linked with hospitality lighting system) ON according to tail 

lamp signal from IPDM E/R

• Controls each illumination (linked with hospitality lighting system) brightness accord-

ing to the illumination control signal from combination meter.
