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-
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.
