INFOID:0000000003762586
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-26, "METER ILLUMINATION CONTROL : System Dia-
.)
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 (through the unified meter
and A/C amp.) 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 enters in the nighttime mode according to position light request signal (through the uni-
fied meter and A/C amp.). Under the nighttime mode the combination meter controls the illuminance by con-
trolling the each illumination lamp (ground side).
