Daytime Running Lights (DRL)

The BCM controls the DRL function. The following conditions must be met in order to allow the DRLs to light:
^ Park brake disengaged
^ Transaxle out of PARK
^ Headlamp switch off
When the above conditions are met, the BCM supplies ground to the DRL relay allowing the relay to engage.
