OUTLINE

Turns the front combination lamps on through the LED daytime, parking lamp control module as the daytime running light.
Daytime running light is controlled by daytime running light control function and combination switch reading function of BCM, and relay control function of IPDM E/R.

DAYTIME RUNNING LIGHT OPERATION

BCM detects the combination switch (lighting and turn signal switch) condition by the combination switch reading function.
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
- Parking brake switch OFF
IPDM E/R controls the daytime running light relay (ground-side) to turn ON according to the daytime running light request signal.
Power is supplied from the daytime running light relay to front combination lamp RH and LH, and then daytime running lamps are illuminated.
