Daytime Running Lamps

WARNING: This page is about a different variant/trim than selected.

Vehicles with the Daytime Running Lamps (DRL) feature enabled illuminate the clearance (position) lamp bulbs in the upper cavity of the two lower front combination lamp units when the engine is running, the parking brake is released, the headlamps are turned OFF, and the optional automatic transmission gear selector lever is in any position except PARK. The park lamps may be ON or OFF for DRL to operate. For vehicles with a manual transmission, the DRL will operate in any transmission gear selector lever position. The BCM must be programmed appropriately for this feature to be enabled.

Once enabled, anytime the BCM receives an electronic message input over the CAN data bus from the EVCU indicating the engine is running, hard wired inputs indicating the left (lighting) multi-function switch is in any position except headlamps ON and the parking brake lever is released, and from the TCM indicating the automatic transmission gear selector lever is in any position except PARK, the BCM energizes a high side driver, which provides battery voltage to the clearance lamp bulbs through the right and left clearance lamp feed circuits.
