System Description

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

Component Description


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 (with CAN communication).
IPDM E/R
 		Controls the integrated relay according to the request from BCM (with CAN communication).
Combination meter
  • Enters in nighttime mode according to the request from BCM (with CAN communication).
  • Controls the each illumination in the nighttime mode.
