Daytime Running Lamp: Description and Operation
DAYTIME RUNNING LAMPS

parking brake is released, the automatic transmission gear selector is not in the Park position and the exterior lamps are turned off. The FCM must be
programmed appropriately for this feature to be enabled. Once enabled, anytime the FCM receives electronic messages over the CAN data bus from the
PCM indicating the engine is running, from the SCM indicating the status of the left (lighting) multi-function switch input is in the Off or Auto positions
and from the EMIC indicating that the parking brake lever is released, the FCM See: Power and Ground Distribution/Power Distribution

produce illumination at a reduced intensity.
