BCM detects the Nissan Murano vehicle condition according to ignition switch.
BCM detects the parking brake condition by the parking brake switch signal received from combination meter via CAN communication.
BCM transmits the daytime running light request signal to IPDM E/R via CAN communication according to the daytime running light ON condition.

Daytime running light ON condition:
- Ignition switch ON
- Lighting switch OFF or 1ST
- Lighting switch AUTO, and the auto light function OFF judgment
