ILLUMINATION CONTROL SYSTEM : System Description
WARNING: This page is about a different car, the 2011 Nissan 370Z. However, it is still accessible from the selected car via links, so may be relevant.
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 "METER ILLUMINATION CONTROL : SYSTEM DESCRIPTION ".)
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
- Lighting switch AUTO, and the auto light function ON judgment
- 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).
