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.
