Control by BCM

• Combination switch reading function
• Headlamp control function

Control by IPDM E/R

• Relay control function

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 (With auto light system)
• IPDM E/R turns the integrated tail lamp relay ON according to position light request signal. It provides the
